Technical due diligence services for investors and acquirers
Commission an independent technical due diligence audit
When you are about to invest in or acquire a SaaS company, you need an objective read on the technology, the team, and the code before the money moves. That is what our technical due diligence services deliver: an independent third-party assessment you can put in front of an investment committee or a board.
This is the engineering half of the diligence. Quality of earnings work and a SOC 2 assessment answer other questions, and a serious deal often needs all three. We do not sell the other two, and we will tell you when they are what you are missing.
We don't rely on magical formulas or famous influencers' opinions. We give you an in-depth technical analysis that goes beyond surface-level assessments, covering code quality and security, architecture and scalability, team and process, so you understand exactly where the risks and the opportunities sit.
Whether you are pricing a seed round, running the technical stream of a series A/B investment, or diligencing an acquisition, the report gives you the clarity and the confidence to make the call.
We are not a typical audit company
We started doing due diligence because investors and VCs have asked us to do so. And after three years, we've done due diligence for 190+ startups all over the world: the Benelux, the DACH region, Scandinavia, the UK, the US and beyond. We are the market leader in Belgium and the Netherlands, and we work remote-first, so where your target company sits does not change how we run the audit.
The same service is described in German and in French. For a German engagement the first call can be held in German, with the audit and the report in English.
Whether you're preparing for a seed round, eyeing a series A/B investment, or approaching a crucial merger or acquisition, our team is here to illuminate the path forward. By partnering with us, you'll gain clarity and confidence to secure your next investment, but also the strategic insight to optimise your technology for long-term success. If you want to see what we assess first, our technical due diligence checklist sets out the five areas and the red flags that matter.
Our 5-pillar methodology
We audit startups and scale-ups using our 5-pillar methodology to produce a due diligence report where we assess 60+ items that help you transition to a quality-first mindset. If one breaks, that promising business you've invested in can soon follow.
01
Team & leadership
Psychological safety, feedback culture, communication flows, and the ability of leadership to scale with the business.
02
Process
Hiring practices, code review workflows, release processes, and whether they balance speed with quality.
03
Written communication
Whether knowledge is documented and accessible, or trapped in people's heads and Slack threads.
04
Engineering
CI/CD pipelines, test coverage, code quality, infrastructure, and the ability to deliver safely and quickly.
05
Problem & solution
Whether the product vision aligns with user needs, and whether the roadmap reflects real business priorities.

Up to 8 interviews & in-depth code review
Deep audit
For Series A/B investments or M&A due diligence. A comprehensive examination of architecture, codebase, team dynamics, and processes, producing a detailed report with 60+ assessed items.
AI readiness, assessed like engineers
Investors now treat AI adoption as a structural question. A team that is not on top of AI carries risk on the balance sheet, and intake forms have started asking for an AI-readiness assessment by name. Our audits answer that question with evidence rather than impressions, in the same report as everything else.
The same applies in reverse. When the codebase itself was largely written with AI, we verify it with the same rigour as any other, plus the questions specific to how it was made.
What we look at:
- →How the team actually uses AI today, checked against the repository rather than taken from the interview.
- →Whether guardrails and review discipline exist, or AI-generated code lands unchecked.
- →Where source code is allowed to go, and whether those controls are proportionate to the other risks we find.
- →Whether what is being spent on AI matches the adoption we can actually observe.
- →How dependent the product is on a single model provider.
- →Whether the codebase is documented well enough for AI tools to work on it safely.

Accelerator program
We like to share what we've learned about startups and scale-ups in the last 15 years.
We can provide technical advice during open office hours, moderate discussions, host workshops, or help put out fires.
Why technical due diligence matters
For SaaS founders, technical due diligence is a critical part of the investment process. It can significantly influence the outcome of funding rounds and strategic partnerships.
Risk mitigation
Early identification of technical issues allows for timely rectifications, reducing potential risks in investments.
Investor confidence
A solid tech DD report reassures investors of the technological soundness and scalability of your SaaS business, making it a more attractive investment opportunity.
Strategic planning
The findings from Tech DD can inform strategic decisions, guiding technology roadmap and resource allocation to align with business goals.

Frequently asked questions
A madewithlove technical due diligence covers five pillars: team and leadership, process, written communication, engineering, and problem and solution. In practice that means interviews with the founders and engineers, a review of the codebase and architecture, and an assessment of security, scalability, and the way the team actually ships. We pull the findings together into a single written report, so you get a rounded view of the technology and the people behind it rather than a shallow checklist.
No. Financial due diligence and quality of earnings work examine revenue recognition, ARR quality, churn cohorts, and the accounts, and that is a job for an accountancy firm. A SOC 2 or ISO 27001 assessment certifies that security controls exist and are operating, which is a job for a compliance auditor. Technical due diligence answers a third question: whether the software, the architecture, and the engineering team can carry the business plan you are underwriting. Most SaaS deals need more than one of the three. We do the engineering one, and we will say so plainly when what your deal actually needs is an accountant or a certification body.
Around two weeks end to end. We validate the key questions with you, run the interviews (up to eight one-hour interviews), carry out an in-depth code review, then fact-check the findings and debrief you. We scope the exact timeline up front and work to your deal timetable.
Investors, acquirers, and boards. Venture capital firms use it to price risk before a seed or series A/B investment. Acquirers use it to understand what they are buying before a merger or acquisition closes. Boards commission it when they want an independent read on the technology behind a company they are backing. In each case you are relying on an objective third party rather than the target company's own account of its technology.
You get a written technical due diligence report. It sets out our findings across the five pillars, flags the technical risks and their likely impact, and highlights the strengths worth protecting. It is written to be read by an investment committee or a board, so it stays clear about what matters for the decision in front of you. We talk you through the report so you can act on it with confidence.
We started doing due diligence because investors and VCs asked us to, and we've now audited 190+ startups worldwide. We don't rely on magical formulas or famous influencers' opinions. Because we have run engineering teams and built software ourselves, we assess the code, the architecture, and the team the way a technical partner would, and we give you an honest read on the risks rather than a reassuring score.
Yes. A growing share of the codebases we assess were written largely with AI tools. We verify quality, security and maintainability with the same five-pillar methodology, and we add the questions specific to AI-built software: whether the generated code is covered by tests, whether anyone reviews what the tools produce, and whether the team can still explain how the system works.
Yes, as a standard part of every audit. We look at how the team uses AI today and check it against what is in the repository, because what shows up in commits, pull requests and documentation is regularly more than what came up in the interviews. We also look at whether guardrails and review discipline exist, where source code is allowed to go and whether those controls are proportionate to the other risks we find, how dependent the product is on a single model provider, whether spending on AI matches the adoption we can observe, and whether the codebase is documented well enough for AI tools to work on it safely.
More often a mismatch than an absence. A pattern we keep seeing: serious money going into AI infrastructure and experimentation while practical adoption in the product stays thin, alongside strict rules to keep source code away from public models while broad production access, shared credentials and secrets sitting unencrypted on machines get far less attention. That goes in the report as one finding about alignment, with the evidence behind it, because what has to change is the order of priorities rather than the tooling.
