Growth is the worst time to discover your product can't handle it. More users, more marketing spend or a new investor all put weight on the same code and infrastructure, and cracks that were invisible at small scale become expensive fast. A technical due diligence is a structured audit that tells you what will break, what it will cost to fix, and what is safe to build on, before you commit the money.
What a technical due diligence covers
- Architecture and scalability: will it hold up at 10x the users, or does it need rework?
- Code quality: is it maintainable, or will every change get slower and riskier?
- Security: exposed data, weak access control, and the risks that become headlines
- Infrastructure and cost: what you run, what it costs, and where that cost explodes at scale
- Team, documentation and ownership: could someone new pick this up, or is it in one person's head?
Signs you need an audit now
- You're about to raise, and investors will run their own technical due diligence
- You're about to spend big on marketing and need the product to survive the traffic
- Releases keep getting slower and small changes keep breaking things
- You inherited the code or the original developers are gone
- Costs are climbing and no one can explain exactly why
What you get out of it
- A clear picture of what's solid and what's fragile, in plain language
- Risks ranked by impact, so you fix what matters before what doesn't
- A realistic estimate of what fixes cost and how long they take
- A go, fix-first, or rebuild recommendation you can actually act on
- Confidence to scale, raise or hand over without nasty surprises
You don't have to commit blind
A full due diligence is a proper piece of work, but the first read doesn't have to be. Most of the time a short conversation about your stack, your traffic and where it hurts is enough to tell you whether you have a small tune-up or a real problem on your hands. That's exactly what our free 30-minute consultation is for: an honest, senior read before you spend anything.
