What is technical due diligence?
Technical due diligence is an independent review of a company’s technology before an investment or acquisition. Stack18 assesses architecture, code quality, security, scalability, infrastructure cost, team strength, AI claims and IP ownership, and reports red flags, their cost to fix and questions for management, usually within two to four weeks under NDA.

Most Technical Due Diligence projects start with a Discovery Sprint (1–4 weeks, fixed price), which fixes the scope, team and price before you commit. Due Diligence Report takes 2–4 weeks at a fixed price. Post-deal Tech Plan takes 2–3 weeks at a fixed price. Prices exclude GST.

How long does technical due diligence take?
Two to four weeks for most startups and mid-size companies, depending on codebase size and access. Urgent reviews can be scoped to one week with a narrower focus.
Will the target company see the report?
That is your decision. We usually share factual findings with management to confirm accuracy, while the risk rating and recommendations stay with the investor.
Do you need access to source code?
Read-only access to repositories, cloud consoles and documentation gives the most reliable result. Where access is limited, we say what could not be verified.
Can you assess AI and machine learning claims?
Yes. We check whether models exist, how they were evaluated, what data they rely on and how dependent they are on third-party providers.
Do you provide Technical Due Diligence across India?
Yes. Stack18 is headquartered in Jaipur, Rajasthan, and delivers Technical Due Diligence for businesses across India, including Delhi NCR, Mumbai, Bengaluru, Pune, Hyderabad and Ahmedabad. Work runs remotely with weekly demos, and on-site workshops are arranged for key milestones.
