How to Select an Investment Banker for the Sale of a Vertical SaaS Company

The banker you hire is not the banker who pitched you. The senior partner with the tombstones and the great stories runs the pitch meeting; a vice president and an analyst run your deal. Most founders select on the partner and live with the associate for nine months. The single most useful question in the whole selection is who, by name, will write the CIM, call the buyers and sit next to you in the management presentations, and how many other live deals those people are carrying this quarter.

The second thing founders get wrong is timing. They call bankers when they have decided to sell, which means the selection happens in three weeks under pressure and the first real conversation about valuation is a pitch. Bankers pitch high to win the mandate. That number becomes an anchor in your head, and it is the most expensive anchor you will carry into the process, because every real offer is measured against it and every one feels like a loss.

Start twelve to eighteen months out. Talk to four or five firms informally, share your numbers, and ask each what the company would need to look like to be an easy deal for them. The ones who tell you something you did not want to hear are the ones worth keeping on the list.

The goal: A banker chosen on evidence — transactions closed in your band, the named team who will do the work, their real buyer relationships — under an engagement letter you negotiated with counsel, with the process design agreed in writing and a weekly cadence running from the day you sign.

Background

What a banker actually does. A good sell-side banker does four things you cannot do yourself: builds and works a buyer list you do not have access to, writes the materials that position the company, runs a process that creates competition and deadlines, and stands between you and the buyer in the negotiation so that you can remain the person the buyer will work for afterward. The fee pays for the competition. A process with one buyer is a negotiation, and you can hire a good M&A lawyer for that. And a banker is not a finder. Anyone who offers to introduce you to "a few buyers" for a fee, without running a process or standing behind the materials, is selling your own contacts back to you.

How bankers are paid. Terms vary widely by deal size and firm, so treat these as the shape rather than the price.

1. Retainer. A monthly or upfront fee, commonly credited against the success fee at close. It keeps the banker committed and it is the fee you pay if the deal dies. Negotiate it down and make sure it is credited.
2. Success fee. A percentage of transaction value paid at close. In the lower middle market it is usually a single-digit percentage, higher on smaller deals and lower on larger ones. Some firms use a Lehman-style ladder, with a higher percentage on the first tranche of value and stepping down; others use a flat rate with an incentive ratchet above a target value. A ratchet that pays the banker more for value above an agreed number aligns interests, provided the number is ambitious rather than the price they expect anyway.
3. Minimum fee. A floor paid regardless of deal size. Fine in principle; check what it implies as a percentage at your realistic value, not the pitched one.
4. Tail. The period after the engagement ends during which a deal with a buyer the banker introduced still earns the fee. Twelve months is reasonable; longer is a negotiation.
5. Expenses. Legal, travel, data room. Cap them.

Process design. The banker will recommend one of three shapes. A broad auction contacts a large list of strategics and sponsors, maximizes tension, and maximizes the number of people who know you are for sale. A targeted process goes to a curated list of perhaps twenty to forty buyers who fit, and trades a little tension for confidentiality and speed. A negotiated sale works one to three buyers who have already shown interest. Strategic buyers pay for the past and the future and usually fit vertical SaaS best, but they are slower, because a champion has to sell the deal internally to a board. Financial buyers pay for the past, move faster to an LOI because fund deadlines and return models drive them, and close faster. The right design follows from the buyer archetype in your Meaningful Exit Plan, not from the banker's habit.

Steps

1. Open informal conversations twelve to eighteen months before your target go-to-market date. Share your financials under NDA and ask each banker the same question: what would make this company an easy deal for you in a year? Take notes on what each one tells you to fix, and compare the lists. Put their answers into your Exit Roadmap if they are right.
2. Build the long list from closed transactions, not reputations. Pull every disclosed sale of a vertical software company in your size band and adjacent verticals over the last three to five years and note which firm advised the seller. Ask your board, your investors, your lawyer and founders who have sold for the names of bankers they would hire again and the ones they would not. A firm that has closed three deals the size of yours in your vertical is worth more than a famous firm for which your deal is small.
3. Cut to three or four and interview each one properly. Two hours, with the CFO and one board member in the room, and insist the people who will work the deal attend. Ask:
   • Who, by name, will do the work day to day, and how many live mandates are they running?
   • Which deals like ours have you closed in the last three years, and what did the seller net against the first IOI?
   • Name ten buyers you would call first, and tell us when you last spoke to someone senior at each one.
   • What would you advise us not to do, and what would make you walk away from this mandate?
   • What is your valuation range, what is it built on, and what would the low end of it look like?
   • Tell us about a process that failed and why.
   • How will you handle a known buyer who has already approached us?
4. Call the references they give you and the ones they do not. Ask two sellers from their recent deals what happened after the LOI, whether the price held, and whether the team that pitched stayed on the deal. Ask one buyer who has been across the table from them whether they ran a real process. A banker who ran tight, honest processes is known for it on both sides.
5. Discount the valuation pitch deliberately. Write down each banker's range and then set it aside. Choose on team, buyer access and process discipline. The banker who pitches the highest number is the one most likely to be negotiating you down from it in month seven, and the one you should trust least on price.
6. Negotiate the engagement letter with your own M&A counsel, not alone. The points that matter:
   • Fee structure, the retainer credit, the minimum fee and any ratchet threshold.
   • What counts as transaction value — whether earnouts, escrows and rollover equity carry the fee at close or only when paid. Push for fee on contingent consideration only when and if it is received.
   • Term, usually twelve months, with your right to terminate on notice.
   • Tail, limited to buyers the banker actually contacted, with a written list delivered at termination.
   • Carve-outs for buyers who approached you before the engagement, at a reduced fee or none, named in a schedule.
   • Exclusivity and what happens if you raise capital or do a recapitalization instead of a sale.
   • An expense cap and indemnification terms your counsel is comfortable with.
7. Agree the process design and write it down before you sign. The buyer universe and how it is split between strategics and sponsors, the target timeline from launch to LOI, who contacts which buyers, what the teaser and CIM will and will not disclose, and which buyers are excluded because they are competitors you will not let see your data. Settle this now, while you still have leverage over the banker.
8. Decide what you will keep for yourself. The banker runs the process; you decide the buyer, the structure and the walk-away. Share your Floor and Enough from the Meaningful Exit Plan only as a floor the banker must clear to bring an offer forward; keep Temptation to yourself and your board.
9. Run the relationship on a fixed weekly call from the day you sign until close. Same day, same hour, thirty to sixty minutes, founder, CFO, banker lead, and a board member when decisions are live. A standing agenda: buyer activity and status by name, diligence requests outstanding and who owns them, documents due this week, issues found, and the one decision needed. The CFO owns the action log and circulates it within a day. When a week passes with nothing to report on buyer activity, that is the finding, and the call should be about why.

Troubleshooting

A strategic has already approached us, so why pay a banker? Because one buyer is not a process, and the buyer knows it. Without an alternative you are negotiating against your own impatience. If you are confident in the buyer, hire a banker on a reduced fee to run a short, targeted check of five or six alternatives, or hire experienced M&A counsel for a negotiated deal. Either way, carve the approaching buyer out of the full fee in the engagement letter.

The big-name bank wants the mandate, and the name will impress buyers. Buyers are impressed by competition, not by letterhead. Ask the big-name bank who will run your deal and how many deals below their usual size they closed last year. If the answer is a junior team and not many, the smaller specialist who closes your size every quarter will work harder and know more of the right buyers.

The banker wants a large retainer. A retainer is reasonable; an uncredited one is not. Pay it, credit it against the success fee, and cap it. If a banker needs a large uncredited retainer to take the mandate, they are telling you how much they believe in the deal.

We picked a banker and three months in the process is going nowhere. Look at the weekly log. If buyer contacts are thin and the named team has changed, raise it directly and in writing. If it does not change within a month, use the termination right you negotiated, and be glad you limited the tail to buyers actually contacted.
