Tech and security diligence, rebuilt for the way deals actually run

3PMA was built by a CISO who has led tech and security due diligence on both sides of the M&A table. It's the platform we wished existed, built because nothing else did the job at deal speed.

Why We Built It

A founder note

Every M&A deal involves tech and security due diligence. In practice, almost none of it gets done well.

I've been a CISO for over a decade. I've sat on the buy side, running diligence on targets we were considering acquiring. I've sat on the sell side, watching prospective buyers parachute in their consultants and produce reports that arrived after the deal closed. And every time, I had the same thought: this whole process is held together with PDFs and goodwill.

The CISO consultants do good work, slowly. The spreadsheet trackers don't survive close. The general-purpose GRC platforms were built for ongoing compliance, not one-shot diligence with a 3-week clock and a thesis attached.

"The whole process is held together with PDFs and goodwill."

So I built the thing I wanted to use. A platform that runs at deal speed, that scales from a 2-day pre-LOI screen to a 3-week confirmatory deep dive, and that doesn't disappear at close. The same workspace runs DD, integration planning, and post-close vendor disposition.

3PMA exists because the deal teams running tech and security diligence today deserve better tools than the ones they have. Every feature in the platform exists because it was needed in a real deal, not because it sounded good in a roadmap.

If you're running diligence on a target right now, or running integration on one you just closed, I'd love to walk through it with you.
