An investor never takes a founder's word for it. Before signing, they score technical debt, security, GDPR compliance, and code ownership on a structured grid. Many CEOs discover this grid exists the moment it gets applied to them, not before.
In Belgium, the twenty largest tech fundraises accounted for 83% of all capital raised in the first half of 2026, according to an analysis by La Libre citing Agoria. Funding is concentrating around a smaller number of companies, and IT due diligence has become one of the filters that decides who gets the check.
IT due diligence is a review of a company's information system, carried out before a fundraise, an acquisition, or a leveraged buyout. It covers architecture, technical debt, security, scalability, the team, infrastructure costs, GDPR compliance, and code ownership. Each area gets a score, and a low overall score triggers deal conditions or a valuation adjustment.
What actually matters isn't what founders assume
Most founders prepare for due diligence by trying to look flawless: zero technical debt, zero incidents, a perfect team. Technical debt exists in every company, to varying degrees. What an experienced investor actually looks for is the team's clarity about that debt, how precisely it's measured, and whether a costed remediation plan exists.
A startup that shows up with an average score and a dated correction plan reassures more than a founder who insists everything is fine without proof. An investor who spots that kind of vagueness asks a simple question: can this team deliver what the business plan promises? When the answer is unclear, the deal slows down or the valuation drops.
The part nobody documents in time
A technical team that ships for clients every day never stops to formalize its own debt, its access controls, or its GDPR register. That work never gets a dedicated sprint, until the day an investment fund asks for it with a two-week deadline.
A Brussels scale-up preparing for a Series A discovered, six weeks before due diligence, that its architecture diagram was two years old and no longer matched the real system. Rebuilding that diagram, sorting outdated dependencies, and documenting access took longer than expected, right when the team should have been focused on the negotiation.
What Nightborn can do upfront
A CEO preparing a deal doesn't always have a senior CTO to run this diagnostic alone, or their technical team is too absorbed in client delivery to audit itself objectively. Nightborn can run this technical review upfront, with a perspective from outside the team, on architecture, infrastructure, and security, through targeted DevOps work focused on the areas most often flagged.
A pre-audit run six months before the deal leaves time to fix what can be fixed, and to document a costed plan for what can't be fixed in that window. No company arrives with zero technical debt. The ones that arrive with a clear measure of that debt change the conversation with the investor.
IT due diligence never punishes one isolated red flag the way it punishes a lack of preparation. If a deal is on the horizon in the next twelve months, the real work is knowing exactly what your tech is worth today, before someone else calculates it for you.
