Tech Due Diligence for SaaS Acquisitions in 14 Days
Comprehensive tech DD for SaaS acquisitions. We uncover hidden risks, assess reproducibility, and quantify technical debt so you can invest with confidence.
Built for Investors Acquiring B2B SaaS
Our SaaS technical due diligence is purpose-built for venture capital firms, strategic acquirers, and corporate buyers evaluating B2B SaaS platforms with ARR between €1M and €10M. At this stage, technical risk is often the largest unpriced variable in a deal.
We help you answer the questions your term sheet cannot: Is the codebase maintainable? Can a new team run this product? What will it cost to fix? We give you the technical clarity to negotiate better, plan integration, and invest with confidence.

What is reproducibility in SaaS due diligence?
Reproducibility assessment evaluates whether the SaaS product can be reliably built, deployed, and operated by a new team after acquisition. We assess CI/CD pipeline maturity, environment consistency, documentation completeness, and knowledge transfer risk — critical factors that are often overlooked in standard technical reviews.
What types of companies is this service designed for?
Our SaaS IT Due Diligence is designed for venture capital firms, strategic acquirers, and SaaS companies preparing for sale or investment. We specialize in B2B SaaS platforms with ARR from €1M to €10M.
Do you support post-acquisition implementation?
Yes, we offer optional implementation support to address identified issues. This includes technical remediation planning, integration architecture design, and hands-on engineering support during the first 90 days post-close.
How much involvement is required from the target company?
We require initial access setup (typically 2–3 hours from their team), followed by 2–3 technical interviews with key engineering personnel. Our process is designed to minimize disruption to the target while ensuring a thorough assessment.
What is the difference between SaaS IT due diligence and general IT due diligence?
General IT due diligence covers a broad range of IT systems and infrastructure. SaaS-specific due diligence goes deeper into cloud-native architecture, multi-tenancy, subscription billing systems, API reliability, deployment pipelines, and the unique scalability challenges of software-as-a-service businesses.
