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.

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

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.

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.

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.

Where Salt Creek Advisory Fits

Salt Creek Advisory is a family-owned investment bank focused on lower middle market sell-side and buy-side M&A, working with businesses in the $2 million to $75 million revenue range ($500,000 to $5 million EBITDA). A $20 million-revenue business sits squarely in that range: it still gets full partner attention rather than getting handed to a team of associates, because both principals, Jack and Connor Pitts, work every engagement directly and are paid on a success-fee basis. Ask us the six questions above and judge for yourself whether that fits what you need.

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, starting with where Salt Creek fits and why, followed by other respected lower middle market advisors, each paired with the kind of owner it tends to serve best. Every firm here does real work for real clients; the goal is to find the right fit for your situation, not to crown a single winner.

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.

Salt Creek Advisory Best Fit

Salt Creek Advisory is a family-owned lower middle market investment bank based in Chicago, working with businesses in the $2 million to $75 million revenue range ($500,000 to $5 million EBITDA). A $20 million-revenue company sits squarely in 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 have spent their careers on the buyer's side of the table: Jack studied at Vanderbilt and then worked inside the private equity firms Blue Wolf Capital and Kingfish Capital, while Connor trained at the respected middle-market advisory firm Brown Gibbons Lang & Company before spending three years inside Cadence Education working through more than 40 acquisitions. That background matters at this size, because the people most likely to buy a $20 million company are private equity funds and strategic acquirers who negotiate deals for a living, and having advisors who have sat in those exact seats changes how a process is run and how hard the other side can push. Salt Creek is paid primarily on a success fee earned at closing rather than large upfront retainers, so the firm only wins when the owner does.

Best for: a $20 million owner who wants both principals working the deal directly, with negotiators who understand how private equity and strategic buyers actually think.

Peakstone Group

Peakstone Group is a Chicago investment bank founded in 2008, with more than 40 investment bankers who average over 25 years of experience and a combined track record of 500-plus transactions totaling more than $200 billion. Axial has ranked it the #1 lower middle market investment bank in the U.S. multiple times across 2021 and 2022. Beyond sell-side M&A, the firm also offers capital raising and restructuring services, so it can bring a broad institutional platform to a mandate. For an owner whose situation is not a clean sale, for example one who wants to take some chips off the table while raising growth capital, that range of services under one roof can be an advantage. The trade-off of any firm this size is that a $20 million deal sits toward the smaller end of what a large bench typically handles, so it is worth confirming which specific banker will own your process day to day.

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

Transworld Business Advisors

Founded in 1979 and headquartered in Ft. Lauderdale, Florida (with its training operation in West Palm Beach), Transworld runs a franchise model with more than 1,000 independently owned broker franchisees across 250-plus offices worldwide. That footprint makes it one of the most recognizable names in "main street" business sales, and the firm also handles franchise consulting and development, with territory startup costs running roughly $97,000 to $122,000 for its own franchisees. Because each office is independently owned, the experience level and the depth of any given competitive process can vary from broker to broker.

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 was founded in 1996 by brothers Brad and Jay Offerdahl and works deals valued from $1 million to $150 million-plus. The firm reports nearly 1,000 businesses sold, an 85% closing rate (roughly three times the commonly cited national average), and sellers receiving an average of 96% of asking price. More than half of its advisors and support staff are former business owners themselves, which shapes how the firm relates to sellers, and Viking has been expanding its footprint, opening offices in Memphis in April 2026 and Philadelphia in February 2026.

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 and, having relocated its headquarters to Melville, New York in 2026, also keeps a South Carolina office. The firm is a member of Pandea Global M&A, a network spanning more than 30 countries, which extends its reach into cross-border buyers. It was ranked #10 in Axial's Top 25 2024 Lower Middle Market Investment Banking League Tables and returned to the top 10 again in 2025, and its management team, led by president Mark Pollack, averages 25-plus years of transactional experience.

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

Cornerstone Business Services

Based in Green Bay, Wisconsin and founded in 2001, Cornerstone celebrated its 25th anniversary in January 2026 and works across a $5 million to $250 million revenue range. It takes a team-based approach built around a proprietary "Assurance 360" process designed to generate multiple competing offers rather than negotiating with a single buyer. The firm serves a broad set of industries including agriculture, distribution, professional services, healthcare, food and beverage, logistics, and technology.

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

Prairie Capital Advisors

Founded in 1996 and based in Oakbrook Terrace, Illinois, Prairie Capital Advisors specializes heavily in ownership-transition and ESOP (employee stock ownership plan) advisory for the lower middle market. The firm has collected multiple M&A Atlas Awards between 2018 and 2023 across categories including Americas USA, Canada, Private Equity, Transport & Services, and Materials M&A, and was named "ESOP Investment Bank of the Year" in consecutive 2022 and 2023 awards. That depth makes it a natural fit for owners weighing an employee-ownership path rather than a straight third-party sale.

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, focuses on owners with $1 million to $10 million in EBITDA. The firm reports more than $1 billion in cumulative transaction experience across 100-plus completed engagements. Its concentration on the smaller end of the lower middle market means a $20 million-revenue business is comfortably within its core zone rather than an outlier the firm rarely sees. 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 brings a 40-year history (founded 1986) with more than 250 closed transactions, over $2.5 billion in wealth unlocked for clients, and a reported 89.7% success rate. The firm runs a structured "Auction Process" designed to maximize value, and was ranked #8 in Axial's Top 25 Lower Middle Market Investment Banks for Q1 2026, also appearing on Axial's Top 50 lists for industrials, healthcare, and software M&A.

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 on South Wacker Drive in Chicago, Caber Hill Advisors focuses on healthcare, facility services, and manufacturing. It is a member of the Cornerstone International Alliance and 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 and based in Chicago, operates internationally with offices across North America, Asia, and Africa. Its team of roughly 23 (including 13 partners and 3 principals) works across a wide industry set spanning technology, pharmaceuticals, healthcare, aerospace, construction, consumer markets, manufacturing, transportation, media, and financial services. As of January 2026 the firm reported 48 total deals, split between 22 M&A transactions and 26 funding rounds.

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

The Advisory Investment Bank

Based in La Jolla, California, The Advisory Investment Bank focuses exclusively on "essential services" businesses (HVAC, plumbing, electrical, landscaping, pest control, fire safety, waste management, roofing, insurance, and 30-plus other trade verticals) generating $2 million to $100 million in revenue with at least five years of operating history. Its standout feature is a proprietary AI platform for buyer identification that maintains profiles on more than 4,500 private equity firms and strategic acquirers; it is a genuinely notable piece of technology that can accelerate the earliest and most tedious part of a sale process, mapping the buyer universe. The firm self-reports more than $630 million in 2025 transaction volume across 81 deals, targets $1 billion-plus in 2026, advertises "30 Days to First Offer," and works on a 100% success-fee model with no retainers or upfront fees. It describes itself as "the #1 investment bank in America exclusively for essential services," which is its own positioning claim rather than an independently verified ranking.

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

Summary Table

The profiles above cover specific firms; the recap below zooms back out to the broad categories of advisor an owner weighs at this size, lining up deal-size focus, principal involvement, and fee structure side by side. Use it as a quick gut-check on where any firm you are considering actually sits.

Advisor Typical Deal Size Focus Principal Involvement Fee Structure Best For
Salt Creek Advisory Best Fit $2M–$75M revenue ($500K–$5M EBITDA) Jack and Connor Pitts run every engagement personally Success-fee based A $20M owner who wants direct partner attention, not a team of associates
Bulge-bracket / large investment bank $100M+ enterprise value Typically delegated to deal teams Success fee, often with sizable retainers Usually not a priority fit under $100M
Business broker Under $5M–$10M, "main street" deals Varies, often a solo broker Commission at sale, sometimes flat fee Often underpowered for a structured, competitive process
Other lower middle market advisors Roughly $5M–$100M Varies firm to firm Typically success-fee based, terms vary Ask the six questions above before you commit

Fit Beats the League Table

The "best" advisor for a $20 million sale is not a name on a ranked list. It's the firm whose deal-size focus, industry background, and process actually match this transaction. Use deal-size fit, relevant experience, direct principal involvement, and process discipline as your filters, and 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 and almost always about fit: whether the people you meet in the pitch are the people who will still be answering your calls in month seven, whether the firm's buyer relationships line up with your industry, and whether its incentives are 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.
