Technical Due Diligence

The independent technical assessment an investor or acquirer pays for before a round or acquisition: code, architecture, team, security, scalability, and key-person risk.

Technical due diligence is what a serious investor or acquirer commissions before money changes hands. It answers one blunt question: does the technology actually support the valuation, or is the story better than the codebase. A proper review covers code quality and maintainability, the architecture and whether it scales past the next order of magnitude, the security posture, the state of the test suite and delivery pipeline, the team’s real depth, and the key-person risk that sits in one founder’s head.

For the buy side, tech DD is risk pricing. You are not looking for perfect code; every company at this stage has debt. You are looking for the gap between what the deck claims and what the repository shows, and for the landmines that turn into post-close emergencies: a single engineer who knows how everything works, a license that poisons a commercial product, a compliance hole, an architecture that cannot survive the growth you are paying for.

For the sell side, getting your own tech DD done before the room does it for you is one of the cheapest ways to protect a valuation. Surprises during diligence cost you leverage; findings you already understand and have a plan for do not. Founders who run a pre-emptive review walk into the data room with answers instead of explanations.

Wavect runs technical due diligence as a senior operator, not a checklist auditor. We have done it on both sides of the table, including data-heavy and regulated platforms, and we write findings a non-technical board can act on. It pairs naturally with our fractional co-founder work, where the same person who assesses the risk can help fix it.

It scales with codebase size, architecture complexity, and how deep the buyer wants to go. A focused review of an early-stage startup runs days; a full assessment of a mature platform with regulatory exposure runs weeks. The cost is trivial next to overpaying for a round on a technology story that does not hold.
Code quality and maintainability, architecture and scalability, security posture, test coverage and delivery pipeline, the depth and stability of the team, and key-person risk. The output is a findings report that prices technical risk in terms a board can act on, not a line-by-line code critique.
Yes, if the round is meaningful. A pre-emptive review turns diligence surprises into prepared answers and protects your valuation. The findings you already understand and have a remediation plan for cost you nothing at the table; the ones the buyer’s team finds first cost you leverage.
