M&A Technical Due Diligence

What the data room
won't tell you.

We surface the technical risk that standard due diligence misses. Hidden liabilities become your post-close problem if you don't find them first.

The Problem

Technical debt doesn't appear in financial models.

It shows up after the close: missed milestones, integration delays, and replatforming costs that weren't in the model. By then, it's your problem to solve.

πŸ“‰
Overvalued Assets

The code doesn't match the pitch

Undisclosed technical debt and architectural fragility routinely inflate software valuations. We quantify what the seller didn't volunteer.

πŸ”—
Integration Surprises

Six-month plans become three-year programs

System incompatibilities and undocumented dependencies turn straightforward integrations into multi-year ordeals. We find them before you sign.

πŸ—ΊοΈ
Misaligned Expectations

Roadmaps without the team to execute them

Sellers present product roadmaps. We evaluate whether the engineering team, architecture, and infrastructure can actually deliver on them.

What We Do

Technical expertise at every stage of the deal.

From first look to post-close execution, we deliver the engineering insight that moves transactions forward with confidence.
