For investors and acquirers

Technical due diligence before you invest or acquire

A pitch deck describes the product; the repository is the product. A technical due-diligence reviewer reads the actual source, the infrastructure and the delivery process, sizes the tech debt, and turns findings into a list the seller can fix before closing, so the buyer doesn't inherit them.

From our experts

Selected cases from these experts’ profiles.

Source-code due diligence across dozens of apps before acquisition

An acquisition holding was buying consumer apps and needed to know what it was really getting. One of our experts, as CTO for M&A code review, read the source of dozens of apps across Swift, Java, C#, Python, Kotlin and React Native, sized the tech debt, and handed the list to sellers. Hundreds of engineer-days of tech debt were found and pushed to the seller side to fix before acquisition.

Due diligence: is the AI in the pitch real?

An investor is about to put money into a company that sells "advanced AI". The expert opens the repositories, documents and transaction records and checks each claim made in negotiations. Sometimes the "neural network" in the pitch is a simple statistical formula.

You get

A yes/no answer on each claim, not a list of nice-to-have fixes.

One-week express audit as technical due diligence

Founders preparing to raise, and investors evaluating a company, need an unbiased technical picture fast. One of our experts runs a one-week express audit: the client picks focus areas (security, compliance, infrastructure cost and reliability, development practices, UX), the expert gets read-only access under NDA, and after a week delivers an actionable report and walks through what to tackle first. Deeper audits and help with fixes follow if needed.

Getting through investor due diligence from the company side

The company went through several technical due-diligence audits by major investors, including a large bank and a large internet group. One of our experts prepared the engineering side: architecture, CI/CD, monitoring with Grafana and Prometheus, incident SLAs and data-protection compliance. They now know both sides of a due-diligence table.

Acceptance requirements that sped up onboarding of acquired apps

After each purchase, the internal R&D team had to take over an app built by someone else, and acceptance dragged. One of our experts wrote clear system requirements that acquired apps had to meet for the internal team. The acceptance pipeline with sellers ran roughly twice as fast.

Questions buyers ask

How long does technical due diligence take?+
A focused review of one product can be done in about a week when the team gives prompt access to code, infrastructure and a technical contact. Larger portfolios are reviewed product by product with the same checklist, so results stay comparable.
What do you get at the end of a tech due-diligence review?+
A written report covering architecture, code quality, security, infrastructure, delivery process and team risks, with the tech debt sized in engineer-days and split into must-fix-before-closing and can-fix-later.
What does a technical due diligence review of an app look like before an acquisition?+
A reviewer reads the actual source code of each app (often across Swift, Kotlin, Java, C#, Python and React Native), estimates the tech debt in engineer-days and lists the fixes the seller should make before closing. One of our experts has reviewed dozens of apps this way for an acquisition holding, which let sellers fix issues before the deal instead of the buyer inheriting them.
What does technical due diligence actually check?+
Whether what the company told investors is true. A due-diligence expert checks the claims made in negotiations against primary sources: the code repositories, documents and real transactions. The answer is close to yes or no: accurate, not accurate, or sincerely mistaken. Recommendations on what to fix are a separate job, an audit. One of Invental's experts does this for investors before they commit.

How it works

  1. Tell us what you need — the repo or system, the question, and the deadline.
  2. We match an expert to your code or system, with a second reviewer where it helps.
  3. Scoped work, contracted through Invental — review per pull request, a fixed-scope audit or architecture review, or ongoing capacity.
