How to choose an M&A advisor: A founder's guide to selecting your most important partner

Two years ago I watched a founder lose 1.1x EBITDA because I picked the wrong advisor. We chased a glossy pitch, ignored the fact they had never closed a deal under $10M, and the buyer used every gap to retrade. That mistake cost the founder about $1.4M and nine months.

Here is the thing: how to choose an m&a advisor is not about logo size. It is about fit, incentives, and process discipline. If you want a clean exit, you need someone who will challenge your numbers early and run a competitive process, not flatter you.

Most founders think the advisor's job is to sell the business. I disagree. The real job is to run a process that protects price, timing, and structure.

When clients ask me how to choose an m&a advisor, I listen for who asks hard questions about cash flow, customer concentration, and contract risk. Those questions prevent retrades later and keep leverage on your side.

• 01Build a buyer universe that can credibly pay
• 02Prepare a defensible earnings story
• 03Control timing and information flow

A good advisor runs a tight process. They build the data room, set deadlines, and control information flow. They do not let buyers drift or renegotiate without cause.

When someone asks how to choose an m&a advisor, I ask how they manage cadence, Q&A, and exclusivity. The answer tells you whether they can protect leverage when the pressure hits.

• 01Weekly buyer updates and clear milestones
• 02Structured Q&A tracking
• 03Rules that prevent silent retrades

Schmidt Logistics in Munich had EUR 8.5M revenue and EUR 1.2M EBITDA. The family wanted a quick exit, but the father and son disagreed on timing. A generic advisor pushed speed and buyers sensed governance risk.

We switched to a team that specialized in family logistics deals and reset the narrative. The process took 18 months, and the deal closed at 7.1x EBITDA. The multiple held because the advisor fit the complexity. If you are earlier in the process and considering a broker instead, understanding how business brokers operate will help you decide which model fits your deal size.

• 01Experience with family governance issues
• 02Patience to run a longer, cleaner process
• 03Ability to keep buyers engaged over time
