Why Technology Due Diligence
In Corporate Investments like Mergers & Acquisitions, Technology Due Diligence is critical to assess and validate the strengths, weaknesses, opportunities, and risks of the target’s tech stack.
TDD is also key to assess the quality and security of outsourced technology services and is a precious aid to help selling founders to prepare for an investor Due Diligence process.

Outcome: Identified critical risks and vulnerabilities, provided a roadmap for post-acquisition improvements.
A venture capital firm required a cybersecurity assessment before investing in a FinTech startup
Solution: We performed a vulnerability scan, compliance review, and risk assessment.
Outcome: Delivered actionable recommendations to strengthen the startup’s security posture.
A venture capital firm required a cybersecurity assessment before investing in a FinTech startup
An Enterprise software house considered the acquisition of a niche SaaS company, whose solution offered a feature missing in our client suite which would have allowed our client to address a new market sector. They were concerned about maintainability and integration of the target solution to their own suite
Solution: Whilst “on paper” the target solution seemed state of the art, a detailed TDD did reveal significant issues with the code base, presenting security and maintainability risks, and making the integration too complex and expensive.
Outcome: Following our recommendations, our customer decided to proceed with the purchase at a revised price, re-build a new version of the solution, and focus on addressing the urgent security and maintainability concerns for the transition period until migration of the target customer platform to the new solution.
