Best Boutique M&A Firms
for Founder-Led Lower Middle Market Companies (2026)

What Makes an M&A Firm “Boutique”

Boutique M&A firms are smaller advisory businesses that specialize in a segment of the M&A market and use lean deal teams. Regional boutiques often advise on transactions worth less than $50 million to $100 million, though no universal cutoff applies. Some boutiques advise on transaction sizes comparable to those handled by large banks. The label describes a business model more reliably than a fixed deal-size category.

Staffing often shapes an owner’s experience more than firm size alone. A specialist boutique may keep a partner or founder involved throughout the transaction. Large banks commonly divide those responsibilities between junior and senior bankers. Junior staff may handle more of the daily work on smaller mandates. Public comparisons of M&A advisor staffing models discuss how firms assign work, but you should confirm who will actually run your engagement.

Boutique investment banks often specialize in a defined market segment. Large regional and bulge-bracket banks usually offer broader services that may include capital raising, securities underwriting, research, and wealth management alongside M&A advisory. Boutique investment bank categories include small regional firms and larger industry specialists, so two firms using the same label may serve very different clients.

A boutique structure does not guarantee greater attention or stronger industry knowledge. Before hiring an advisor, confirm who will work on your transaction. Ask about each advisor’s workload and experience with companies of your size.

How Boutique Fee Structures Typically Work

Boutique M&A firms usually earn most of their compensation through a success fee paid when a transaction closes. Some firms also charge an upfront or monthly retainer for preparation and buyer outreach. Advisors commonly credit those payments against the success fee, although each engagement letter sets its own terms. Other firms use a success-fee-only model with no upfront retainer. Salt Creek Advisory follows this approach for standard M&A engagements, earning its advisory fee only when a transaction closes.

Advisors may calculate success fees with a tiered formula often called a Lehman scale. Under the original formula, the advisor earns a declining percentage on each additional portion of transaction value. Modern versions use different percentages and breakpoints, so the actual formula matters more than its label. Some firms instead charge one percentage across the full transaction value or add an incentive fee above an agreed valuation threshold. Lehman-style structures vary widely, and firms usually negotiate them for each engagement.

Fee percentages generally decline as transaction size rises because the fee applies to a larger value base. Axial’s 2026 M&A Fee Guide, which surveyed 331 advisory firms in the second quarter of 2026, found average effective success fees of about 3.4 percent on $20 million transactions and 2 percent on $100 million transactions. Deal size benchmarks from that survey provide context, but they do not replace a written proposal.

You should confirm how the advisor treats debt, earnouts, rollover equity, reimbursable expenses, and minimum fees. The engagement letter should define the fee calculation base, including whether it uses enterprise value or equity value and how it treats proceeds received.

Disclosure and Methodology

Salt Creek Advisory created this article. We selected firms using publicly available information from company websites and other primary sources.

We evaluated each firm based on its stated deal size focus, service model, level of principal involvement, and disclosed fee structure. When a firm did not publish specific information, we noted that limitation rather than making an assumption. We did not assign scores or ratings.

Salt Creek Advisory leads this comparison as the strongest fit for founder-led lower-middle-market companies. The remaining firms appear alphabetically, since owners may choose among them based on their companies, transactions, preferred fee structures, and desired levels of senior attention.

Boutique M&A Firms at a Glance

Use the table to narrow the field by company size, transaction needs, and preferred service model before reviewing each firm’s detailed profile.

Salt Creek Advisory

Overview

Salt Creek Advisory is a family-owned M&A advisory firm based in Chicago. Our founders, brothers Jack and Connor Pitts, remain directly involved throughout each engagement rather than handing the work to a junior team.

Best Fit For

Salt Creek suits owners who want senior attention during a lower-middle-market sale. Our service model may also appeal to owners who value targeted, confidential buyer outreach and candid advice about when to sell.

Typical Client or Transaction Size

Typical clients generate about $2 million to $75 million in annual revenue and at least $500,000 in adjusted EBITDA. Adjusted EBITDA estimates operating earnings after removing interest, taxes, depreciation, amortization, and certain unusual expenses.

Industries Served

Salt Creek focuses on early childhood education, manufacturing, industrial services, distribution, business services, managed IT services, and pet care. Sector familiarity helps us identify relevant buyers and explain the business in terms those buyers understand.

Geographic Coverage

Salt Creek serves privately held companies across the United States while maintaining a Chicago and Midwest presence.

Core Services

Sell-side M&A advisory is the primary service. Salt Creek also provides preliminary valuations, buyer identification, transaction preparation, offer evaluation, due diligence coordination, negotiation support, and closing support.

Notable Strengths

Clients work directly with Jack and Connor throughout the sale process. Salt Creek charges no upfront retainer for standard M&A engagements and earns its advisory fee only when a transaction closes.

We use our own software and AI tools to research buyers and organize market information and deal activity. Jack and Connor retain responsibility for financial analysis, relationships, confidentiality, and negotiation.

Potential Considerations

Salt Creek is smaller and serves a narrower company-size range than a large institutional investment bank. Owners pursuing transactions that require extensive cross-border or capital-markets work may need the broader staffing and services of a larger firm.

Owners should still review fee and termination terms in the full engagement agreement, including any post-termination obligations.

Amherst Partners

Overview

Amherst Partners is a Michigan-based financial advisory firm with an established Midwest presence. The firm reports more than 450 completed domestic and cross-border engagements representing more than $20 billion in transaction value.

Best Fit For

Larger family-owned companies may find Amherst well suited to complex transactions that require broader financial advisory capabilities. The firm also works with private equity firms, independent sponsors, and corporations.

Typical Client or Transaction Size

Amherst does not state a narrow transaction range in the information reviewed. Its experience and service model suggest a stronger fit for larger or more complicated middle-market mandates.

Industries Served

Public information presents Amherst as serving a broad client base rather than concentrating on one industry.

Geographic Coverage

Amherst operates from Michigan and serves clients across the United States. Its cross-border experience can support transactions involving international buyers or counterparties.

Core Services

The firm advises on mergers and acquisitions and capital raising. Amherst also provides restructuring and management advisory services.

Notable Strengths

Amherst combines significant transaction experience with hands-on senior advisor involvement. Its capital-raising capabilities and cross-border resources can help when a transaction requires more than a standard company sale.

Potential Considerations

Smaller sellers may not need Amherst’s broader, more institutional service model. Public information reviewed for this article does not clearly disclose its retainer or success-fee practices, so owners should ask about fee terms and minimum engagement expectations.

Why Included

Amherst represents the more institutional end of boutique M&A advisory in the Midwest. Its experience with private and family-owned companies makes it relevant for owners evaluating larger or structurally complex transactions.

ButcherJoseph & Co.

Overview

ButcherJoseph & Co. advises founder-owned, family-owned, and employee-owned businesses. The firm supports third-party sales, employee stock ownership plan transactions, capital raises, valuations, and fairness opinions.

Best Fit For

Owners considering an ESOP or comparing employee ownership with a third-party sale should consider ButcherJoseph. Its broader capabilities may also fit larger or structurally complex transactions that require several financing or ownership options.

Typical Client or Transaction Size

Public information provided for this review does not specify a typical transaction size. Its institutional service model appears oriented toward larger or more complex mandates.

Industries Served

ButcherJoseph presents its work around ownership type and transaction structure rather than a narrow industry specialty.

Geographic Coverage

Public information provided for this review does not define a specific geographic range.

Core Services

The firm advises on sales to strategic and financial buyers, ESOP transactions, debt and equity capital, valuations, and fairness opinions.

Notable Strengths

ButcherJoseph combines investment banking execution with deep employee-ownership expertise. Its valuation resources and ability to evaluate several transaction structures can help an owner compare alternatives before choosing a path.

Potential Considerations

Owners committed to a straightforward third-party sale may not need the firm’s ESOP and capital advisory capabilities. A deeper execution bench may also provide a different client experience than a small firm built around continuous founder involvement. Public information provided for this review does not specify its fee structure.

Why the Firm Was Included

ButcherJoseph offers a distinct option for founders and families evaluating employee ownership alongside a conventional sale. Its range of transaction capabilities separates it from boutique M&A firms focused mainly on selling companies to outside buyers.

Calder Capital

Overview

Calder Capital combines business brokerage and M&A advisory with digital marketing, buyer outreach, and technology-enabled business development. Its broad transaction range distinguishes it from firms that focus on a narrower part of the market.

Best Fit For

Owners of manufacturing, construction, distribution, and business services companies may find Calder’s industry presence and buyer network useful. Its model can accommodate both smaller business sales and larger M&A engagements.

Typical Client or Transaction Size

Calder advises transactions with enterprise values generally ranging from $1 million to $100 million.

Industries Served

The firm has a strong presence in manufacturing and industrial services. Calder also serves construction, distribution, and business services companies.

Geographic Coverage

The available information does not define a limited geographic service area. Owners should confirm Calder’s buyer coverage and transaction experience in their specific market.

Core Services

Calder provides business brokerage, M&A advisory, digital marketing, buyer outreach, and technology-enabled process management.

Notable Strengths

Calder supports a wide transaction-size range and maintains an established buyer and investor network. Its educational content and digital marketing capabilities can help attract buyer interest, while its technology supports outreach and process organization.

Potential Considerations

The combination of brokerage and M&A advisory deserves close review if you want a confidential, targeted process rather than a listed-business approach. Owners should ask how Calder structures outreach, assigns senior professionals, and separates its brokerage model from its investment banking work.

Why the Firm Was Included

Calder represents a distinct model among boutique M&A firms. Its broad size coverage and combination of brokerage, advisory, digital marketing, and technology make it relevant for owners comparing different sale processes.

Dresner Partners

Overview

Dresner Partners is a Chicago investment bank focused primarily on sell-side M&A for lower-middle-market and middle-market companies. The firm brings more than 30 years of operating history and a FINRA-registered investment-banking platform.

Best Fit For

Larger founder-owned and family-owned companies may benefit from Dresner’s institutional capabilities, especially when a transaction requires senior banker attention or access to international buyers.

Typical Client or Transaction Size

Dresner serves lower-middle-market and middle-market companies. Public information does not provide a specific transaction value range.

Industries Served

The firm emphasizes industry specialization and deep sector experience, though the available information does not identify its full sector coverage.

Geographic Coverage

Dresner has a strong Chicago presence and reaches buyers across the United States and international markets.

Core Services

Its services include sell-side M&A, capital raising, restructuring, valuation, and strategic consulting.

Notable Strengths

More than three decades in business give Dresner established credibility in Chicago. Senior banker involvement, cross-border capabilities, and significant transaction experience support larger or more complicated mandates.

Potential Considerations

Dresner operates with a more institutional orientation than some smaller boutique M&A firms. Owners at the smaller end of the lower middle market should ask how their engagement would rank among the firm’s other mandates and which senior bankers would handle the work. Companies seeking a straightforward sale may not need its broader capital advisory and restructuring capabilities.

Why the Firm Was Included

Dresner represents the established end of the boutique investment bank category. Its history, senior-level service, and domestic and international buyer access make it a relevant option for owners evaluating a larger or more complex sale.

MelCap Partners

Overview

MelCap Partners is an independent investment banking firm founded in 2000 and based in Greater Cleveland, Ohio. The firm advises privately held middle-market companies.

Best Fit For

Owners of established companies may consider MelCap when a transaction requires middle-market experience and access to international buyers.

Typical Client or Transaction Size

MelCap works with companies that generally have $10 million to $250 million in sales. Companies below $10 million in revenue may fall outside its typical focus.

Industries Served

MelCap works across industries. Publicly disclosed transactions include specialty food ingredients, but the firm does not present itself as limited to that sector.

Geographic Coverage

The firm maintains a strong presence in Northeast Ohio and the Great Lakes region. Its Globalscope membership connects it with 53 firms and more than 600 investment bankers across 42 countries.

Core Services

MelCap provides sell-side and buy-side M&A advisory, private placements, distressed transaction advice, business valuations, and feasibility studies.

Notable Strengths

Globalscope gives MelCap international reach while preserving a boutique service model. That network may help owners whose buyer pool includes overseas strategic acquirers or investors.

Potential Considerations

MelCap does not publicly disclose whether it charges an upfront retainer or relies on a success fee, so owners should ask about engagement terms. Securities are offered through its broker-dealer affiliate, M&A Securities Group, Inc., and owners should understand that entity’s role.

Why Included

MelCap combines a Cleveland middle-market presence with international buyer access. Its stated company-size range makes it relevant for larger founder-owned and family-owned businesses considering a sale or recapitalization.

Peakstone Group

Overview

Peakstone Group is a Chicago-headquartered investment bank that advises entrepreneur- and family-owned companies. Its services include M&A advisory, capital raising, and strategic advisory.

Best Fit For

Larger founder- and family-owned businesses should consider Peakstone when a transaction requires experienced senior bankers, broader capital options, or access to international buyers.

Typical Client or Transaction Size

Peakstone states that its clients generally produce approximately $10 million to more than $500 million in revenue. That range places the firm above many smaller business brokers and lower-middle-market advisors.

Industries Served

The firm works across industries. Its recent experience includes pet services, where it advised family-owned Paws Pet Resort on its January 2025 sale to Best Friends Pet Care.

Geographic Coverage

Peakstone operates from Chicago and maintains relationships with buyers and capital providers globally.

Core Services

The firm provides sell-side and buy-side M&A advice, capital raising, and strategic advisory services.

Notable Strengths

Peakstone brings an established transaction history and an institutional service model to founder-owned company sales. Its recent pet resort transaction may interest owners in boarding, daycare, training, and related pet services.

Potential Considerations

Companies below $10 million in revenue may fall outside Peakstone’s stated focus. Owners closer to the $2 million to $10 million range should ask how the firm would staff and prioritize their engagement, since its broader platform may provide more infrastructure than a smaller transaction requires.

Why the Firm Was Included

Peakstone represents the more institutional end of the boutique M&A category. Its Chicago presence, broad revenue range, and ability to handle larger or more complex transactions make it a relevant option for established founder- and family-owned companies.

How to Choose the Right Option

Start with the advisor’s usual transaction range. Your company should represent a meaningful engagement for the firm, since attention and staffing often follow deal economics. Larger banks generally focus on large, complex transactions, while boutiques often serve founder-owned companies at smaller enterprise values, according to a comparison of advisory models.

Industry experience matters when buyers assess specialized revenue or regulatory issues and the company’s customer relationships. A sector-focused boutique may already know the relevant buyers and common diligence issues. A broader firm may fit better when your company operates across industries or could attract several distinct buyer groups.

Geography should match the likely buyer market rather than your headquarters alone. A local advisor may work well when buyers are concentrated nearby. A company with national or international appeal may need an advisor with wider buyer relationships and experience coordinating outreach across regions.

Match the firm’s capabilities to the transaction you are considering. A standard company sale requires different experience than an employee stock ownership plan or a recapitalization in which you retain equity. Ask who will handle business valuation, buyer outreach, negotiations, and due diligence before signing an engagement. A step-by-step guide to choosing an M&A advisor can help frame these questions before the first call.

Personal priorities should shape the final choice. Direct access to senior advisors may matter if you want close involvement in each decision. Salt Creek Advisory is designed for owners who prioritize that access, with Jack and Connor Pitts involved throughout the engagement. Fee structure, confidentiality practices, communication style, and sensitivity to employees or family expectations can also affect your experience.

Use these questions to compare firms.

• Does the advisor regularly represent companies of your size and complexity?
• Can the firm identify credible buyers in your industry and target geography?
• Has the advisor handled the transaction structure you are considering?
• Who will perform the daily work and lead negotiations?
• How do retainers, success fees, minimum fees, and reimbursable expenses affect your total cost?
• Does the proposed process reflect your priorities for confidentiality, employees, legacy, and closing certainty?

Frequently Asked Questions

What does “boutique” mean in M&A?

A boutique M&A firm usually focuses on advisory work within a defined segment of the M&A market and uses a smaller staffing model than a large investment bank. Salt Creek operates as a founder-led boutique for lower-middle-market business owners, with Jack and Connor Pitts directly involved throughout each engagement. Working directly with Jack and Connor Pitts may give you more senior attention and a sale process suited to the size of your company.

How do boutique M&A fees compare with larger investment banks?

Boutique fees commonly combine a closing-based success fee with an upfront or monthly retainer, although terms vary by firm and transaction. Salt Creek charges no upfront retainer for standard M&A engagements and receives its advisory fee when a transaction closes. This structure reduces the owner’s upfront cost, but the engagement agreement still determines minimum fees, expense reimbursement, fee calculations, and post-termination obligations.

Can a boutique firm run a competitive process for a smaller deal?

A competitive process identifies suitable buyers, controls outreach, compares offers, and supports negotiations through closing. Salt Creek approaches qualified strategic buyers, private equity firms, family offices, and other acquirers for founder-owned lower-middle-market companies. You can evaluate multiple options while keeping outreach targeted and confidential.

Talk to Salt Creek Advisory

The right advisor should match your company’s size, transaction structure, likely buyer market, and need for senior involvement.
