Three Guardrails That Keep Acquirers Honest During Diligence

I've never found the start of a diligence process in a fundraise or M&A transaction stressful. The stress comes at the end.

You have one acquirer in the mix. You're locking down final terms. Deal docs are starting to get drafted.

And then, with the finish line in view, one last diligence request comes in.

Your acquirer asks for direct access to your engineers, your source code, and your production environment. They want to meet with your head of AI to better understand the algorithms that drive your product.

You want to prove you have nothing to hide. You believe full transparency will clear the path to a close.

Here's the risk.

Their junior engineers start pinging your developers on Slack at all hours. Your CTO gets pulled into a series of unstructured calls. Their engineers start nitpicking your team's code in every meeting.

Even if you're running low on cash, a structured approach to tech diligence can save a deal.

If you don't control the flow of information, they extract the blueprint, kill the deal, and build it themselves.

Here's how you protect your IP and still get the deal done.

👉 Define strict guardrails for communications

Don't let the acquirer's team talk directly to yours without a gatekeeper. Every request goes through your CFO, COO, or banker. No exceptions.

If a member of their team tries to go around you, make sure your team immediately flags it and redirects the inquiry. You need to set the flow of information, not them.

👉 Constrain access to your systems and IP

Deny root access, downloadable source code, and admin credentials to any production environment until the deal is signed. This is not negotiable.

When you do show the technology, your technical lead shares their screen. You walk them through the architecture. Nobody gets credentials.

If they absolutely need hands-on access to non-sensitive data, set up a locked-down, read-only environment. They can look, but they can't copy or download.

👉 Don't underestimate the power of reps and warranties

Diligence means verifying the asset exists. Knowledge transfer happens after the deal closes.

Never let them blur together.

Your acquirer will insist that they need to have full access to your code to prove it works as advertised. That's not true. Those M&A agreements come with reps and warranties you'll sign. You're personally on the hook if the tech isn't what you said it was.

Those legal protections are powerful. Your acquirer knows that. Use them to protect your code and your team until the deal is done and the cash is wired.

This isn't just about protecting your code; it's a test. If an acquirer dismisses strong reps and warranties and still demands unfettered access to your source code, they aren't trying to buy your company. They're trying to steal your roadmap.
