The most dangerous moment in a startup is when the product is working just well enough to raise money but not well enough to survive what comes after.
Most founders don't find out their codebase has fundamental problems during development. They find out during due diligence, when an investor's technical advisor spends three days in the repository and comes back with a list. Or they find out post-raise, when the team tries to move fast and everything starts breaking in ways nobody can fully explain.
By that point, the cost isn't just technical. It's momentum. It's trust. It's six months of engineering time going backwards instead of forward.
Technical due diligence exists to prevent exactly that — but most founders treat it as something that happens to them rather than something they initiate.
At HiQByte we do pre-raise and pre-engagement technical reviews. Not audits. Not reports designed to justify a rebuild. Honest assessments of where a codebase actually stands — what's solid, what's fragile, what will hold under pressure and what will not.
We look at architecture decisions and whether they were made deliberately or by accident. We look at dependencies and what happens when they break. We look at the areas of the system that nobody on the current team fully understands anymore — because those exist in every product past a certain age, and they are always the first things to fail.
The output is clarity. A founder who knows exactly what they're sitting on makes better decisions — about hiring, about roadmap, about what to tell investors and what to fix before they walk in the room.
We've done this for founders before a raise, businesses evaluating an acquisition, and teams inheriting a codebase from a previous agency. Every single time, the findings changed something important.
If you have a product that's been built and you've never had an outside eye on the architecture — that's worth fixing before the moment it matters most.

Has anyone here gone through a technical due diligence — either pre-raise or post-acquisition? What did you find that surprised you most?
