FAQ

A technical audit is an in-depth review of your software architecture, technical debt, security, and development practices. It helps you spot risks, validate an investment decision, and get recommendations you can actually act on. At CO-CTO, every audit is run by an experienced CTO who has personally built and scaled production systems.

A strategic technical audit is for CEOs and boards who want to understand the health of their own system. Technical due diligence happens as part of a financial deal (fundraising, acquisition): it's about validating or challenging the tech valuation of a target company. The two have different goals and deliverables, but they complement each other.

The cost depends on the size of your company, how complex your architecture is, and the type of audit you need (strategic, due diligence, compliance, operational). At CO-CTO, our audits are run by experienced CTOs at rates built for startups and scale-ups. Get in touch for a quote tailored to your situation.

A standard technical audit usually takes 2 to 4 weeks, including the debrief and recommendations. For due diligence tied to an acquisition, we adapt the timeline to your constraints and can move in accelerated mode if needed.

There are a few key moments: before a fundraise, to prep for due diligence; when you're seeing warning signs (late releases, recurring bugs, infrastructure costs spiraling); during a change in technical leadership; or as part of an acquisition. It's always better to run an audit before a crisis hits than to react to one.
