When Should You Hire an Investment Banker?

The honest answer: earlier than you think, and for fewer things than you might expect.

Investment banking has a reputation problem in the lower middle market. Too expensive. Too slow. Adds a layer between you and the buyer. Takes a percentage of a deal you could have done yourself. Some of that reputation is deserved — for some deals, with some bankers. But the question of when to hire one is worth thinking about carefully, because the cost of getting it wrong runs in both directions.

What a banker actually does

At its core, an investment banker in a private company transaction does three things: runs a process, creates competition, and manages the information asymmetry between you and buyers or investors.

Process matters more than most founders appreciate. A well-run sell-side process — controlled outreach, phased information disclosure, coordinated timing across multiple buyers — creates competitive tension that a direct bilateral negotiation almost never does. The difference between one interested buyer and three is not just better terms. It's better information about what your business is actually worth.

Information asymmetry management is subtler but often equally important. Buyers and investors do this for a living. They have seen hundreds of companies in your category. They know what the market clears at, where the bodies are buried in businesses like yours, and which terms to push on. A banker who has been on the other side of that table understands what's being done and can push back.

When you need one

For a sell-side M&A process involving a meaningful transaction — generally above $5 million in deal value — the math almost always works in favor of representation. The question is not whether the banker fee is large. It's whether the banker generates enough additional value (through price, structure, or terms) to cover the fee and then some. In competitive processes, the answer is usually yes.

For equity raises above $2 to $3 million, the calculus is similar. A banker with real investor relationships and a disciplined process can get you in front of the right investors faster, with better positioning, than you can do yourself while also running your company. The opportunity cost of a founder spending six months managing a raise is real and often underestimated.

The cost of getting the banker question wrong runs in both directions.

For restructurings and distressed situations, you almost always need one — both for the financial expertise and for the credibility it signals to lenders and counterparties that you are managing the situation professionally.

When you don't

For very early-stage raises — friends and family, angels, pre-seed — the fee structure of professional banking rarely makes sense and the relationships that close those rounds are usually personal. You don't need a banker; you need introductions.

For a direct bilateral negotiation where you already know the buyer and have reason to believe it's the right deal at the right price, the value of a full process is lower. You may still want legal and financial advice, but a formal banking mandate may be more structure than the situation requires.

For strategic conversations that are genuinely exploratory — you're talking to a potential acquirer and want to understand whether there's something there — you can often run that conversation yourself. If it progresses to a real process, that's when you bring in representation.

The timing problem

The most common mistake is hiring a banker too late. By the time a founder has a term sheet in hand, the process is already determined. You're negotiating against a buyer who has done their diligence, formed their view on price, and constructed terms favorable to them. Walking in a banker at that stage is difficult and often counterproductive.

The right time to engage is before the process starts — ideally 60 to 90 days before you want to be in front of buyers or investors. That window allows for proper preparation: positioning the business, building materials, identifying the right universe of counterparties, and structuring the outreach so it creates competition rather than desperation.

What to look for

Relevant transaction experience in your sector and size range. References from founders who have actually closed deals with them — not just started processes. A principal who will be on your deal personally, not a senior partner who signs the engagement and hands it to a junior team. And honest advice about whether a process makes sense, not just enthusiasm about starting one.

The best banking relationships I've seen start with a frank conversation about whether a transaction is the right move, whether the timing is right, and what the realistic range of outcomes looks like. A banker who tells you what you want to hear is not doing their job.

The question isn't whether bankers are worth it in the abstract. It's whether the right banker, at the right time, for the right transaction, creates more value than they cost. Usually the answer is yes. Rarely is the answer yes for everything.
