The professional buyer no longer opens your Excel. They open your API.
Until 2023 a mid-market M&A deal worked like this: NDA signed, information memorandum exchanged as PDF, two months of email Q&A, a couple of in-person visits and a valuation based on what the buyer assumed was true.
In May 2026 that sequence no longer exists. Serious buyers — PE funds, family offices and sophisticated strategics — come to the table with three things they didn't bring before:
- A proprietary AI model trained on thousands of deals in your sector. It knows what discounts to apply before reading your memorandum.
- Technical capacity to audit your stack live. If you grant CRM or accounting access, their agent analyzes cohorts, retention and margin in hours, not weeks.
- A defensible opinion on what you're worth — before you open your mouth.
Founders who don't know this lose the deal before it starts.
Three concrete things that have changed in 18 months
1. Due diligence now takes 3 weeks, not 3 months
A European mid-market fund told us this week they went from 11 weeks to 23 days of average DD on their last 4 closed deals. The difference? A 2-person in-house team + agentic AI that extracts, normalizes and cross-references dataroom information against proprietary benchmarks.
The collateral effect is brutal: the founder who shows up with messy numbers can no longer hide in process slowness. What used to be "we'll send it later" for weeks is now an explicit discount the following Monday.
2. Red flags surface without anyone asking
The buyer's agent doesn't get tired, doesn't forget and isn't polite. If your real margin per business line doesn't reconcile with your annual accounts, it detects. If your reporting mentions "external consultant" without a contract, it flags. If your top client represents 31% but the deck says "concentration under 25%", it shows up highlighted in red on the investment committee dashboard.
Buyers no longer search for data. They verify it.
3. Negotiation starts with your valuation, not their offer
In 6 of the last 10 closed deals we've seen in the market, the first document exchanged after the NDA was a buyer-side valuation memo — partly generated by AI — with their own range. No more "send us your pricing". It's "this is what we think you're worth and here are the 4 adjustments we're making. Anything to add?".
If you've never sat in that position, you arrive lost. If you've done a serious Phase 1 before going to market, you arrive with your own quantified adjustments — and the conversation shifts from fight to model comparison.
What this means for your company, today
If you're thinking about selling in the next 24 months, three things are no longer optional:
A) Your reporting has to be machine-readable
A decent P&L isn't enough. You need structured exports, reconciled, with metadata. If the buyer has to ask their team to normalize your spreadsheets for a week, that week turns into a DD discount of 5-15% of initial valuation.
B) Your growth narrative has to survive automated cross-checking
If your memorandum says "MRR grows 8% monthly sustained" but backend data shows 4% real and 4% from accounting reclassification tricks, the buyer's agent will find it. And then you don't buy the deal at a good price — you lose trust, which is the only thing that justifies a high multiple.
C) Your team has to be able to speak with live data
Buyers want interviews with your 3-4 key executives. Before it was theater: the CEO spoke, the others confirmed. Now they prepare questions with their AI after auditing the dataroom and compare every answer against data. If your CFO doesn't know real CAC over the last 6 months, you lose valuation every time they hesitate.
The part no one tells you: your own AI analysis is now an advantage
The same shift that makes buyers more sophisticated opens a brutal lever for you:
- You can simulate how each buyer type will see your company before they see it. That's what we do in Phase 1: we run your numbers through the benchmarks a mid-market fund would use and show you the discount they'd apply — so you fix it first.
- You can document critical processes at AI speed instead of consultant speed. What used to take 6 months now takes 8 weeks with a small team and good models. That's the heart of Phase 2.
- You can audit your own growth narrative against the same red flags the buyer's agent would detect. If it doesn't hold up, you discover it first — and fix, not hide.
The uncomfortable point
AI won't buy your company. Humans will, at human tables, with human fears and human egos. That hasn't changed.
What has changed is that those humans come to the table with a level of information you don't yet have about yourself. That asymmetry gets paid for, and it gets paid in closing price.
The founder who understands this and prepares — with us or any other serious team — walks into the deal with the conversation leveled. The one who doesn't discovers the discount when it can't be negotiated anymore.
In 2026, the big difference between the top and bottom quartile of mid-market closings is not the sector, the macro cycle, or luck. It's how much AI work you've done on yourself before the buyer does it.
If you believe your company will be on a deal table in the next 24 months and you've never done that exercise, that's exactly the conversation we have in the 15-minute strategic call. No pitch. No commitment. If you don't fit our profile, we tell you where to start.
