Best M&A Advisors for Selling
a $20 Million Company in 2026

Why Deal Size Changes the Advisor Search

At roughly $20 million in enterprise value, most transactions fall into what is commonly called the lower middle market, generally defined as businesses with $5 million to $100 million in revenue or a similar range in transaction value. This size band has its own dynamics:

• Large investment banks (bulge-bracket and most middle-market banks) typically focus on transactions well above $100 million and may not prioritize a $20 million deal.
• Business brokers often work smaller "main street" transactions and may not run the kind of structured, multi-buyer process that maximizes value at $20 million.
• Lower middle market M&A advisors and boutique investment banks are built specifically for this range: sized to give a $20 million deal real attention without the overhead of a large bank. Our companion guide to top lower middle market investment banks covers this category in more depth.

Understanding where your deal falls helps narrow the search before you evaluate individual firms.

Four Decisions in a $20 Million Sale

Our investment bank roster compares firms by reputation and rank. A $20 million seller needs a narrower test. These four questions decide how the sale actually goes.

Who will staff my deal?

At a large bank, $20 million is a small mandate, and small mandates tend to drift to the most junior people on the team. Ask for the name of the person who will write your materials, call buyers and sit across the table at the letter of intent. At Salt Creek Advisory that is Jack and Connor Pitts on every engagement, from the first call to the wire. There is no hand-off to a junior team.

How far will the buyer outreach go?

A business this size draws private equity platforms, add-on buyers, strategic acquirers and family offices. Offers improve when buyers know they are not the only one at the table, so ask how many buyers the advisor contacted on its last comparable deal and how that list was built. Salt Creek maps the buyers worth calling for each business, vetted by hand, and targets first offers within 30 days of launch. A typical lower middle market sale closes in six to nine months. See how a competitive auction process works.

What will I pay in total on a $20 million deal?

Using the Firmex benchmarks covered below, a success fee of 3.4% to 3.9% on a $20 million sale comes to roughly $680,000 to $780,000. Many advisors also bill an engagement fee during the process. Firmex puts the typical one at $5,000 to $10,000 a month; over a six-to-nine-month process (our illustrative assumption, not a Firmex figure), that adds $30,000 to $90,000, which may or may not be credited back at closing. Our advisor fee guide lays out the fee models side by side.

How will the offer be structured?

At $20 million, the headline price is rarely all cash at closing. Offers can carry rollover equity, an earnout, escrow or holdback, a seller note, and a working capital peg that moves the final check. Two offers with the same headline number can leave you with very different amounts. Ask each advisor how it compares offers on cash at close and risk, not just price. Our guide to M&A deal structure covers each piece.

Salt Creek vs. the other kinds of advisor

What Advisors Actually Charge at $20 Million

Fee talk usually stays vague until an engagement letter lands in front of you, which is backwards: the fee structure is one of the few things you can benchmark before you ever take a meeting. The most useful public benchmark is the M&A Fee Guide that Firmex has run annually since 2016 in partnership with Axial and Divestopedia. Its 2023–24 US edition, built from 189 US respondents (six in ten investment bankers, about 30% business brokers), models a success fee of 3.9% on a $20 million deal, against 6.3% at $5 million and 2.0% at $100 million. The more recent 2024–25 global edition, drawing on 456 respondents across 49 countries, models the same $20 million deal at 3.4%, with 4.8% at $5 million and 2.0% at $100 million. Call it roughly 3.4% to 3.9% at this size. The consistent pattern across every edition is that the percentage falls as deal size rises, so a quote well outside that band deserves an explanation.

The structure underneath the percentage varies more than the percentage itself. The single most common approach is a Lehman-style formula in which the rate declines as the price climbs, used by 51% of US respondents in the 2023–24 edition and 41% globally a year later. The classic version charges 5% on the first million, 4% on the second, and so on down to 1% above $5 million; the widely used "Double Lehman" variant starts at 10% and falls to 2%. About a third of advisors skip tiering entirely and charge a flat percentage, and 16% use an accelerator that pays them more above an agreed target price, which can be a genuinely useful way to align an advisor with a stretch outcome.

Then there is the part owners tend to overlook. In the US edition, three-quarters of advisors charge some sort of engagement fee, and the typical engagement letter built from the most common answers includes a monthly work fee of $5,000 to $10,000; roughly a quarter charge nothing upfront (the newer global edition puts the no-work-fee share at 19% among North American firms). Firmex also found that ongoing monthly fees have become more common than the one-time upfront retainer most firms charged the year before. In practice, an engagement fee is owed while the engagement runs and usually is not refunded if the deal never closes, which moves real risk from the advisor onto you. The detail that matters most is whether that money comes back to you: only 54% said they credited the engagement fees paid towards the success fee, so nearly half keep it on top. Ask two specific questions of every finalist: what is the engagement fee, and is it credited against the success fee. Get both answers in writing.

None of this makes retainers illegitimate. A firm doing serious preparation work deserves to be paid for it, and a nominal retainer can be a reasonable test of whether a seller is genuinely committed. The point is that "success fee" and "no retainer" are not interchangeable claims, and the difference between a credited and a non-credited work fee on a $20 million deal can run into six figures.

What "Best" Actually Means at This Size

Instead of chasing a generic ranking, evaluate advisors against the criteria that actually affect your outcome:

• Relevant deal experience. Has the firm closed transactions in a similar revenue range and industry, or adjacent ones?
• Who does the work. Will a managing director or partner run your deal day to day, or will it be delegated to junior associates once you sign the engagement letter?
• Process discipline. Ask how many buyers the firm actually contacted on its last closed deal in your size range, not just how many expressed interest.
• Buyer network fit. Does the firm have real relationships with the strategic acquirers, private equity firms, and search funds that actually buy businesses like yours?
• Fee structure. Does the advisor make most of their money from a success fee paid at closing, or would you still owe substantial retainers even if the deal never closes?
• Communication style. Do you get direct answers on a call, or a sales pitch that avoids specifics?

The reason these criteria beat a generic ranking is that a $20 million sale is not a commodity transaction. Two firms can both be excellent and still be wrong for each other, one built for cross-border strategic buyers, the other for regional financial buyers, and the mismatch only shows up months into a process when it is expensive to switch. Judging advisors against the factors above forces the conversation onto the things that will actually move your outcome: who runs the deal, how they run it, and whether their buyer relationships overlap with the acquirers most likely to pay a premium for a business like yours.

What the League Tables Do and Do Not Tell You

Several firms in this article cite a ranking, and those rankings are not all the same thing, so it is worth being precise about which ones carry weight. The most credible source in this segment is Axial, a lower middle market deal network that publishes a quarterly Top 25. Axial states that its rankings are "based entirely on first-party Axial data drawn from every stage of eligible deals marketed on the platform" and that "no self-reported data or paid placements factor into the results," scoring firms on client quality, buyer targeting, and process effectiveness rather than raw deal count. That is a materially better methodology than a directory that sells placement, and when a firm below cites an Axial rank, we treat it as a real signal.

It has one structural limit worth understanding, and Axial is open about it. Only "active investment banking and M&A advisory members of the Axial platform" in good standing that "marketed at least one deal that received investor interest during the ranking period" are eligible. So the Top 25 is a rigorous ranking of firms that use Axial and ran a qualifying deal that quarter, not a survey of every advisor in the country. A strong firm that sources buyers through its own relationships and never lists on the platform cannot appear, and neither can one that had a quiet quarter. Salt Creek Advisory is not on these tables. Read a high Axial rank as real evidence of process effectiveness within that pool, and read its absence as no evidence either way.

Treat other signals more carefully. Awards are verifiable when the awarding body publishes its own winners, which is why we link to the awarding organization rather than the firm's press release wherever possible. Self-reported statistics (close rates, aggregate transaction volume, "#1" claims) are not independently audited, and we label them as self-reported throughout rather than repeating them as established fact.

How We Evaluated These Firms

Every firm below was assessed against five criteria that determine whether it fits an owner selling a business around $20 million. First, does its stated deal range genuinely include a company this size, rather than treating it as an outlier at the bottom of the range. Second, who does the work: does a principal or managing director run the process, or does it pass to junior staff after signing. Third, is the fee structure disclosed clearly enough to compare against the benchmarks above. Fourth, does the firm have demonstrable reach into the buyers most likely to acquire a business in your sector. Fifth, is its claimed track record verifiable from a source other than its own marketing.

Where a claim comes only from a firm's own website or press release, we say so and cite it to that firm rather than presenting it as independent fact. Where a figure is a career-long total across a team's whole working history rather than the firm's own deal count, we flag the distinction, because the two get conflated constantly in this industry. Where we could not confirm something, we left it out instead of filling the gap with marketing language. We also include firms that compete directly with us and describe honestly what they do better than we do.

Questions to Ask Before You Hire

Once you have narrowed the field, a short, direct conversation tells you more than any pitch deck. These six questions are designed to surface how a firm actually operates rather than how it markets itself.

1. How many transactions has your team closed in my industry or a similar one?
2. Who exactly will be handling my deal day to day, and how often will I actually hear from that person?
3. What does your typical buyer outreach process look like: how many buyers, and how are they sourced?
4. What is your fee structure, and how much is contingent on a closed transaction?
5. Can you walk me through a recent process, without disclosing confidential details, from engagement to close?
6. How long, realistically, should I expect this process to take from start to close?

What Matters Most at $20 Million

Beyond the advisor's resume, a few practical factors tend to matter most for a $20 million sale:

• Alignment of incentives. A success-fee-based structure generally means the advisor is only paid when you are.
• Bandwidth. A firm handling too many deals at once may not be able to give yours the attention it deserves.
• Confidentiality practices. Ask exactly how the firm keeps your name out of the market before a buyer signs an NDA.
• Cultural fit. You'll be working closely with this person through months of due diligence and buyer negotiations, so make sure it's a relationship you actually want, not just a resume you're impressed by.
• Buyer-side perspective. Advisors who have worked inside private equity firms or as acquirers often anticipate the questions, diligence requests, and negotiating tactics a buyer will use, which can help you prepare before those pressures arrive rather than reacting to them mid-process.
• Industry-specific reach. A generalist can run a competent process, but a firm that already knows the active acquirers in your sector can often reach the right buyers faster and frame your business in the language those buyers use to value companies like yours.
• Valuation grounding. Before you compare advisors, it helps to know roughly what your business is worth and how buyers will price it. Our guides to EBITDA and valuation basics and the best business valuation firms for a sale cover how that number gets built, and strategic versus private equity buyers explains why two credible bidders can value the same company differently.

None of these factors is decisive on its own. The point is to weigh them together against your specific situation, rather than defaulting to whichever firm has the largest logo or the longest track record on paper.

Best M&A Advisors for a $20 Million Company Sale

Owners selling a $20 million company tend to research the same short list of firms before deciding who to call. Below are twelve worth knowing. Salt Creek Advisory is our top pick for a founder-owned $20 million sale, for the staffing, buyer outreach and fee reasons above. The other eleven are respected lower middle market advisors, each paired with the kind of owner it tends to serve best, and several are the better call for the situations we name.

As you read, it helps to notice what distinguishes these firms from one another, because at a glance many of them look similar. A few, like Peakstone and Madison Street, are larger platforms with deep benches and international reach. Others, like Hill View Partners and Salt Creek, are deliberately small so that the senior people stay on your deal from first call to close. Some specialize by transaction type, such as Prairie Capital's ESOP focus, and others by industry, such as Caber Hill in healthcare and facility services or The Advisory in essential-services trades. A handful are franchise or network models that trade consistency for reach. None of these approaches is inherently better; the question is which one matches the business you are actually selling and the outcome you care most about, whether that is the highest headline price, the most certainty of closing, or a specific structure like employee ownership.

Comparison at a Glance

Before the profiles, here are all twelve firms side by side. Ranks shown are Axial league-table placements, which carry the methodology and the eligibility limits described above; everything else is each firm's own stated focus. Salt Creek Advisory is our pick for best overall; the other firms follow the order of the profiles below, which is not a ranking among them.

Salt Creek Advisory Best Overall

Salt Creek Advisory is our pick for the best M&A advisor for a founder-owned company selling at around $20 million. It is a family-owned lower middle market investment bank based in Chicago, with Midwestern roots and national reach, working only for sellers with $2 million to $75 million in revenue ($500,000 to $5 million EBITDA). A company selling for around $20 million, or one with $20 million of revenue, sits inside that band, which means it gets the founders' direct attention rather than being routed to a rotating cast of associates. Co-founders Jack and Connor Pitts run every engagement personally, and both know the buyer's side of the table. Jack graduated from Vanderbilt, worked in private equity business development at Blue Wolf Capital and Kingfish Capital, and worked in investment banking at ButcherJoseph & Co. Connor spent about five years in corporate development at Cadence Education across two stints, with a few months in investment banking at Brown Gibbons Lang & Company in between, and worked on more than 40 transactions from the buyer’s side, mostly at Cadence. That background matters at this size. The people most likely to buy a $20 million company are private equity funds and strategic acquirers who negotiate deals for a living. Having advisors who have sat in those exact seats changes how a process is run, and how hard the other side can push. The firm is paid a success fee at closing, with no retainer and no monthly fees; some engagements begin with a small deposit that is credited against that fee. That structure ties almost all of what we earn to your deal closing.

Who should pick someone else. Because both founders work every deal, we run a small number of engagements at once, and there are periods when we cannot take a new mandate. Our sector depth is in early childhood education, business services, industrials, MSP and IT services, and pet care; an owner selling a healthcare services business or a specialty manufacturer in a vertical we do not know well is better served by a firm that already knows those acquirers. We are a young firm without a decades-long transaction list or a league-table rank, and some owners will want that history. If you need an ESOP, a genuine cross-border auction, or a capital raise alongside a partial sale, several firms below are a better fit, and we would rather say so here than three months into a process.

Best for: a founder-owned company selling at around $20 million that wants both principals working the deal directly, sell-side only, with no retainer or monthly fees. If you need an ESOP specialist, cross-border reach, or deep expertise in a sector we do not cover, choose accordingly from the firms below.

Peakstone Group

Peakstone Group is a large Chicago investment bank that Axial ranked #1 in the lower middle market in Q2 2021, full-year 2022, and full-year 2024, and #15 in Q3 2026; it also offers capital raising and strategic advice alongside M&A. Its stated client range starts at $10 million of revenue and runs past $500 million, so a $20 million deal sits toward the smaller end of what it typically prioritizes, so confirm which specific banker will run your process day to day. Full profile: Peakstone Group.

Best for: owners who want a large, deeply staffed platform and are comfortable being one mandate among many.

Transworld Business Advisors

Transworld Business Advisors is a franchise network of 1,000-plus brokers across 250-plus offices, built for smaller main-street sales rather than a $20 million, multi-buyer process. Because each office is independently owned, experience varies by franchisee, so confirm the specific broker's track record at your size before engaging. Full profile: Transworld Business Advisors.

Best for: owners of smaller, simpler businesses who want a local broker and don't need a structured, multi-buyer investment-banking process.

Viking Mergers & Acquisitions

Viking Mergers & Acquisitions works deals from $1 million to $150 million-plus out of Charlotte, North Carolina, reporting 950-plus businesses sold and an 85% close rate (self-reported). It fits owners in Viking's Southeast and Mid-Atlantic footprint who value advisors who have owned businesses themselves. Full profile: Viking Mergers & Acquisitions.

Best for: owners in Viking's Southeast and Mid-Atlantic footprint who value working with advisors who have run companies themselves.

Protegrity Advisors

Protegrity Advisors focuses on the $10 million to $100 million revenue range from Melville, New York, and belongs to the Pandea Global M&A network spanning 30-plus countries, useful if your buyer pool may extend overseas. Axial ranked it #10 in 2024 and #12 in 2025. Full profile: Protegrity Advisors.

Best for: owners who want access to an international buyer network alongside a focused lower middle market practice.

Cornerstone Business Services

Cornerstone Business Services, based in Green Bay, Wisconsin, works a $5 million to $250 million revenue range with a team-based "Assurance 360" process built to generate multiple competing offers, a fit for owners who want a larger internal deal team rather than a single point of contact. Full profile: Cornerstone Business Services.

Best for: owners who want a larger internal team and a defined process aimed squarely at driving competitive offers.

Prairie Capital Advisors

Prairie Capital Advisors, based in Oakbrook Terrace, Illinois and itself majority ESOP-owned, specializes in ownership-transition and ESOP advisory, with M&A Atlas Awards from Global M&A Network between 2018 and 2024. If an ESOP is on the table at $20 million, this is the specialist worth calling. Full profile: Prairie Capital Advisors.

Best for: owners specifically exploring an ESOP or a structured ownership transition.

Hill View Partners

Hill View Partners, founded in 2016 by Arthur Petropoulos and based in Providence, Rhode Island, splits its practice into two explicit tracks: a core group serving owners with $5 million to $20 million of EBITDA, and a separate "1-to-4" track built for owners with $1 million to $4 million of EBITDA (Hill View). That structure is worth noting, because it means a smaller business is served by a team organized around smaller businesses rather than squeezed into a process designed for larger ones. The firm reports more than $1 billion in cumulative transaction experience across 100-plus completed engagements, and Axial ranked it #3 on its Top 25 Lower Middle Market Investment Banks for Q1 2026 (Axial). A company selling for around $20 million usually has a few million dollars of EBITDA, which puts it in the 1-to-4 track rather than Hill View Core, but either way it is a size the firm sees regularly rather than an outlier. That focus is worth weighing carefully: an advisor who works this size band every week tends to have realistic expectations about valuation, buyer behavior, and timelines at this level, instead of applying assumptions borrowed from much larger transactions where the buyer universe and negotiating dynamics are different.

Best for: owners at the smaller end of the lower middle market who want a boutique that lives in that range every day.

ACT Capital Advisors

ACT Capital Advisors, based in Mercer Island, Washington, brings a 40-year history (founded 1986) with more than 300 deals and over $2.5 billion in wealth unlocked for clients (ACT), and reports an 89.7% success rate, a figure the firm calls "industry-leading" and that is not independently audited. The firm runs a structured "Auction Process" designed to maximize value, and Axial, an independent M&A network, ranked it #8 on its Top 25 Lower Middle Market Investment Banks for Q1 2026 (ACT). It has also appeared on Axial's Top 50 sector lists for industrials (2026), healthcare (2023), and software (2022) M&A advisors.

Best for: owners who want a long-tenured firm with a formal, competitive-auction methodology.

Caber Hill Advisors

Founded in 2014 by Craig Castelli and based in downtown Chicago (Caber Hill), Caber Hill Advisors focuses on healthcare, facility services, and manufacturing. It is a member of the Cornerstone International Alliance (Cornerstone International Alliance) and, per Axial's Top 25 Lower Middle Market Investment Banks for Q1 2026, was ranked #20 (Axial). It positions itself deliberately between local business brokers and large investment banks. That middle position can suit owners who want more process than a broker typically runs but less overhead than a national bank. Its industry concentration is the thing to weigh here: a firm that already knows the active acquirers in, say, healthcare services can often reach the right buyers faster and speak their valuation language, which matters more in specialized sectors than a generalist's broader but shallower reach.

Best for: Chicago-area owners in healthcare, facility services, or manufacturing looking for a specialized boutique.

Madison Street Capital

Madison Street Capital, founded in 2005, is now headquartered in Austin, Texas, with additional offices including Chicago (Madison Street), and reports a presence across North America, Africa, and Asia, though it does not name a specific Asian office. Axial, an independent M&A network, ranked it #5 on its Top 25 Lower Middle Market Investment Banks for Q1 2026 (Axial) and #4 for Q3 2026 (Axial). The firm works across a wide industry set spanning technology, pharmaceuticals, healthcare, aerospace, construction, consumer markets, manufacturing, transportation, media, and financial services.

Best for: owners who specifically need international buyer reach or a mix of M&A and capital-raising support.

The Advisory Investment Bank

The Advisory Investment Bank focuses exclusively on essential-services trades from $2 million to $100 million in revenue, backed by a proprietary AI buyer-sourcing platform; Axial ranked it #1 overall for Q1 and Q2 2026 and #2 for Q3 2026. It is a strong fit for a $20 million trades business, and a mismatch for anything outside its niche. Full profile: The Advisory Investment Bank.

Best for: owners of trades and essential-services businesses who want deep vertical focus and an AI-accelerated buyer search.

Fit Beats the League Table

The best advisor for a $20 million sale is not the top name on a league table. It is the firm whose deal-size focus, staffing, buyer reach and fees match this transaction. For most founder-owned companies at this size, that is Salt Creek Advisory, for the staffing and fee reasons laid out above. Hold us to the same test as everyone else. Call two or three firms, ask them the six questions above, and choose based on how they actually answer, not how their marketing reads.

Most of the firms profiled here are credible operators with real track records; several would do a capable job with the right client. The differences that matter at $20 million are rarely about competence in the abstract. They are about fit. Will the people you meet in the pitch still be answering your calls in month seven? Do the firm's buyer relationships line up with your industry? Are its incentives tied to closing your deal at the right number? A short, honest comparison against those questions will tell you more than any league table, and it costs nothing but a few conversations before you sign anything.
