Should you hire an investment banker to sell your company?

Should you hire an investment banker to sell your company?

If your company is worth roughly $5 million or more and more than one buyer could plausibly want it, yes. Below that size, or when exactly one buyer exists and speed matters more than price, an honest advisor will tell you not to hire them. The rest of this page is the reasoning, including the cases where the answer is no.

The decision turns on one mechanism. Price in a private sale is set by competition, not by negotiation skill. A buyer facing no rival prices your company against your alternatives, which are weak the moment you have decided to sell. A buyer facing two rivals prices it against losing the deal. Everything an advisor does, the buyer research, the positioning, the parallel outreach, the managed timeline, exists to build that second situation and hold it through closing. If your situation cannot support competition, most of the fee buys process management rather than price, and you should weigh it accordingly.

What does an advisor actually change?

Four things, in order of value. First, competition and therefore price: the gap between what a serial acquirer pays in an unbanked bilateral negotiation and what the same business clears in a competitive process is large enough that Windsor Drake publishes its measurement as The Windsor Drake Proprietary Discount Index. Second, survival through diligence: most value lost in a sale is lost after the handshake, through retrades in week six, and an advisor who has seen the playbook defends terms a founder concedes. Third, your own attention: a sale is a second full-time job for six to ten months, and buyers count on deal fatigue, because a founder who has stopped running the business needs the deal to close more than the buyer does. Fourth, a buffer: someone else pushes back hard so that you can keep the relationship you will need if that buyer becomes your acquirer, or remains your competitor.

When is hiring a banker a waste of money?

Three situations, stated plainly. If your company would sell below roughly $2 to $3 million, fee floors consume the economics and a quality business broker is usually the right tool; the difference is explained in business broker versus M&A advisor. If there is genuinely one logical buyer, a strategic that owns your distribution or your platform dependency, a full process cannot manufacture competition that does not exist, though a compressed market check can still test the assumption cheaply. And if you are unwilling to spend the months a process takes, or the business cannot withstand the scrutiny, the honest move is to fix the business first, which is what exit readiness work is for.

What should you look for before hiring one?

Six checks separate advisors, and none of them is the brand on the door. Sector depth: the advisor should name the likely buyers of your specific company in the first meeting, from relationships rather than a database export. Senior attention: the person who pitched you should be the person running your deal, which you ask directly and then fix in the engagement letter by name. Conflicts: a firm that also runs buy-side mandates or lends to acquirers has an interest in the other side of your table; sell-side-only practices exist precisely to remove that. Fees: get the structure in writing before you sign anything, and read how sell-side fees actually work, including the Lehman formula variants most firms quote. Published work: ask to see how the advisor thinks, not who they have banked. Research, data, fees, and process documentation published in public show you the work before you pay for it; a firm that can only show a logo wall is showing you deals someone else may have staffed. Capacity: ask how many mandates the senior banker is running concurrently, and treat a volume shop’s answer as a warning.

What does it cost?

Windsor Drake sets out its fee structure before a founder commits rather than quoting it late in a selection process: a monthly advisory fee and a graduated success fee that rises with transaction value. Terms are set against the size and complexity of the mandate. The balance between advisory fee and success fee is adjusted case by case, including success-fee-only engagements, with total economics held consistent across structures. The comparison that matters is not fee against zero. It is fee against the discount an unbanked process accepts, and that discount is the largest number on this page.

Where do you start if you are only exploring?

Privately, and without committing to anything. Three steps come before any outreach. Get a real read on value from someone who sees current transactions rather than a formula, because the number in your head is the most dangerous input in the process. Assess whether your numbers would survive diligence, since every weakness costs more discovered late than disclosed early. And decide your walk-away terms while nothing is at stake, because deciding them mid-negotiation means deciding them under pressure. Exploration is confidential by construction, which is covered in full in how a confidential sale process works. The worst starting point, and the most common one, is answering a single inbound buyer without knowing what the competitive alternative would produce. That specific situation has its own playbook: Approach Response.

Questions founders ask

Should I hire an investment banker to sell my company?

Above roughly $5 million in value with more than one plausible buyer, yes: competition sets price, and a banker exists to manufacture and hold it. Below that size, or with a single logical buyer and a speed priority, the fee can outweigh the benefit.

What should I look for in a sell-side M&A advisor before hiring them?

Sector depth with live buyer relationships, the senior person running the deal rather than delegating it, a sell-side-only practice without buy-side conflicts, written fees you understand, published work that shows how the advisor thinks rather than a logo wall, and honest answers on concurrent mandate load.

I want to explore a sale. Where do I start?

Three private steps before any outreach: a transaction-grounded read on value, an honest diligence self-assessment, and your walk-away terms decided in advance. Exploring commits you to nothing.

How much does it cost?

Windsor Drake sets out its full fee structure before you commit: a monthly advisory fee plus a graduated success fee that rises with transaction value, so the firm is paid more only by delivering a higher price. Exact terms are stated in writing before any engagement.

A buyer already approached me. Do I still need one?

That is the case where an advisor changes the outcome most, because a lone buyer prices the absence of competition. A compressed market check can create real alternatives without restarting your timeline.
