M&A advisor vs. business broker vs. investment bank.
Deal size decides. Business brokers list companies under $5M on marketplaces. M&A advisors run confidential, competitive processes for $3M–$100M companies. Investment banks serve deals above $50M. For a founder-led software company in the $3M–$50M range, a specialized M&A advisor is almost always the right model.
Which type of firm fits which deal size?
Each of the four tiers of M&A representation has a defensible economic model — but each model only works at specific deal sizes. The costly mistake is applying the wrong tier to your deal: paying for capacity you won't use, or economizing on a process that demands institutional discipline.
| Firm Type | Typical Deal Size | Fee Structure | Process Model | Best For |
|---|---|---|---|---|
| Business Broker / Marketplace | Under $5M | 10–15% commission, no retainer | Public listing; inbound buyers | Micro-SaaS and small digital businesses |
| M&A Advisor (boutique specialist) | $3M–$100M | Retainer + 2–7% success fee, retainer credited at close | Confidential, competitive auction | Founder-led software companies |
| Mid-Market Investment Bank | $50M–$500M | Retainer + 2–4% success fee | Institutional process, PE sponsor coverage | $100M+ deals needing institutional scale |
| Bulge Bracket Bank | $500M+ | 1–2% success fee | Global coverage teams | Mega-deals and sale-vs-IPO dual tracks |
What does a business broker actually do?
A business broker lists your company on a marketplace, screens inbound buyers, and facilitates negotiations as they come in. It's a listing model, not a strategic process — there is no equivalent of a competitive auction in the brokerage world.
The buyer pool is transactional: search funders, individual investors, and small platforms shopping listings. And the listing itself is public — discoverable by employees, customers, and competitors. For most software founders, the confidentiality difference alone makes the choice.
None of this makes brokers wrong — below roughly $3M–$5M in enterprise value, the deal is genuinely too small to support advisory economics, and a marketplace is the rational route. The problem is applying the listing model to a company that institutional buyers would compete for.
What does an M&A advisor do differently?
An M&A advisor runs a structured, confidential, competitive process with institutional buyers — a phase-gated timeline from preparation through buyer outreach, management meetings, LOI, diligence, and close.
Confidentiality is engineered into every step: blind teasers that don't name the company, NDA-gated confidential information memoranda, and outreach limited to a curated list of qualified acquirers. Advisors maintain ongoing relationships with strategic buyers and PE platforms — they call named partners at named firms, rather than waiting for inbound interest.
The difference shows up hardest in negotiation. Advisors run multiple buyers in parallel to create competitive tension, then negotiate the full structure — earnouts, escrow, indemnification, rollover equity, and management protections — against professional counterparties. Synoptic M&A™ is how iMerge structures that process.
When do you need an investment bank?
Above roughly $100M in enterprise value — and almost never below $50M. Mid-market investment banks (Houlihan Lokey, William Blair, Baird) engage at $50M–$100M+ with dedicated software teams and deep PE sponsor coverage. Bulge bracket banks (Goldman Sachs, Morgan Stanley) hold minimums of $500M+.
The fee economics are the tell. When a large bank accepts a mandate below its minimum, the deal gets junior staffing and partial attention — the senior team that won the pitch isn't the team running your process. For lower-middle-market software deals, bulge-bracket tactics fail on attention, not capability.
The exceptions are narrow: $500M+ tech deals and dual-track sale-versus-IPO situations, where global coverage genuinely matters. More on the mid-market dynamics in Investment Banking for Lower-Middle Market Software.
Is hiring an M&A advisor worth the fee?
The data on outcomes is unusually clean: represented sellers achieve materially higher valuations and better terms than unrepresented sellers — by margins that are many multiples of the fee.

How should a $3M–$50M software founder choose?
Apply the size rule. Under $3M–$5M in enterprise value — usually below $1M–$2M ARR for SaaS — the brokerage model can make sense. Above that line, an advisor-run process produces materially better outcomes on price, structure, and confidentiality. Above $100M, mid-market banks enter the conversation.
In the $3M–$50M range, a boutique software specialist is the only tier where you are simultaneously a priority deal and the firm has institutional-grade infrastructure to run a competitive auction — senior partners running the deal personally, with software-specific buyer networks.

Frequently asked questions.
What's the difference between an M&A advisor and a business broker?
An M&A advisor runs a structured, confidential, competitive process with institutional buyers — blind teasers, NDA-gated materials, curated outreach, and negotiated deal structure. A business broker lists your business on a marketplace and facilitates inbound interest. There is no equivalent of a competitive auction in the brokerage model.
Do I really need an investment banker to sell my SaaS company?
Yes, in almost every case above $3M to $5M ARR. A University of Alabama and Portland State University study of over 4,400 transactions found represented sellers received valuation premiums of around 25% — many multiples of the typical 4–6% fee. Even 99% of PE firms hire external advisors when selling their own portfolio companies.
How much does each type of firm charge?
Business brokers charge a 10–15% commission on smaller deals, with no retainer. M&A advisors charge a retainer plus a 2–7% success fee, with the retainer credited against the fee at close. Investment banks charge a retainer plus 1–4% depending on deal size, with minimums that price out most deals under $50M.
Can a business broker sell a $10M software company?
Technically yes, but the model works against you. A listing-based process isn't designed to price recurring revenue, retention, or the metrics institutional software buyers pay premiums for. Founders in the $5M–$50M range who take the brokerage route consistently leave 30–50% of value on the table versus a competitive advisory process.
When is a business broker the right choice?
Below roughly $3M–$5M in enterprise value — for SaaS founders, usually under $1M–$2M ARR. At that size the deal is too small to support advisory economics, and a marketplace listing to individual buyers and search funds is the rational route.
Will a broker's public listing expose my sale to employees and competitors?
It can. A marketplace listing is discoverable by anyone — employees, customers, and competitors included. M&A advisors run the opposite model: blind teasers that don't name the company, NDA-gated materials, and outreach limited to a curated buyer list. For most software founders, confidentiality alone decides the question.
What questions should I ask before hiring an M&A advisor?
Ask the same five questions of every candidate: closing rate over the last 24 months, active engagements per senior advisor, who runs the deal day to day, the last 10 closed transactions in your size range, and their approach to AI positioning if it's relevant to your company. Specificity in the answers is the test.
