Technical audit and due diligence for startups and investors
Our experienced CTOs and staff engineers technically de-risk your next funding round. In only 2 weeks. About 90% of funded startups fail within 3 years. The biggest risks are not the pitch or market fit, they are the hidden flaws in the product or the team.
Our technical due diligence explained in 1 minute
We help startups, scale-ups and investors with technical due diligence by objectively evaluating the codebase and the technical team to ensure your next funding round is fully technically de-risked.
Buyers and investors call this work by different names. Software due diligence, technology due diligence and tech DD all describe the same engagement, and in a merger or acquisition it usually runs as the technical workstream alongside financial and legal diligence. The term varies by deal team. The work does not.
Know where you stand
- - Is your software solution ready to scale?
- - How much legacy code and technical debt does your product have?
- - What is limiting velocity?
- - What is preventing the team from delivering higher quality?
- - Can you scale with your current team, technology, and processes?
Our sample report shows exactly how we answer these questions.
Our approach to technical due diligence
Team & leadershipProcessWritten communicationEngineeringProblem & solution
Our unique methodology is based on 5 pillars, because just analysing the code or exploring documentation is nowhere near enough.
Step 1
The Baseline Interview
2-hour call with the CTO
We start with a baseline interview covering key players and areas to focus on. We prepare 3 to 5 key questions and schedule placeholder interviews.
Step 2
Strategic preparation
Planning
After the baseline interview, we know who we want to talk to and the important systems to review. We ask for access to codebases, ticketing systems, and documentation tools.
Step 3
Interviews and code review
Reviewing everything
Our team dives deep, checking for best practices across systems. During interviews, we zoom in on specific details to understand how a team thinks about their work.
Step 4
The report
Documenting findings
We document our observations and concerns, share a draft with the company, then refine the finished version and share it with the recipients.
Step 5
The debrief
Answering your questions
We debrief the report after people have had a chance to read it. We even join board meetings if necessary. From the first interview: 10 business days.
AI readiness, assessed like engineers
“How mature is this team's AI adoption?” has joined the standard questions an audit is expected to answer, and we answer it the way we answer everything else: by looking at the code and talking to the people who write it.
That cuts both ways. A codebase largely written with AI gets the same scrutiny 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.
Why companies call us in
You don't call us when everything's fine. You call when you need clarity about your technology before making a big decision.
“We’re afraid AI-generated code is quietly piling up technical debt.”
“We’re dealing with legacy systems nobody fully understands.”
“Madewithlove was the only party advising us to refactor instead of starting over. With hindsight, this was the right choice. Our customers started feeling the difference right away and didn’t have to…”
Steven Debrauwere, CEO at Contractify
“Our codebase was built with AI and nobody has verified it.”
“We acquired a company and need to evaluate the tech.”
“Madewithlove helped us build the blueprint, not the house. Advice was given in a fair and direct way, while keeping room for discussion and without pushing personal preferences.”
Robin Haegeman, CTO at 3D Aim Trainer
“We want to prepare for our next funding round.”
“Our team says everything is fine, but delivery keeps slipping.”
“A strong partner for tech due diligence: clear, rigorous, and always pragmatic, with reports that are easy to navigate and act on.”

We help our clients succeed
You will not see companies like Amazon among our past clients. You will, however, see the names that will soon rock the SaaS world because we helped them predict risks and avoid failure.
“Madewithlove was the only party advising us to refactor instead of starting over. With hindsight, this was the right choice. Our customers started feeling the difference right away and didn’t have to wait 9 months or longer for improvements.”
Steven Debrauwere
CEO, Contractify
“Madewithlove helped us by providing a critical eye for our situation then got their hands dirty, got involved to fix problems, to put us on a better path.”
Dorian de Broqueville
General Manager, Izix
“Madewithlove’s audit was thorough and fair. They asked insightful questions on both the architecture and purpose of our technology. They quickly understood the value of our vehicle routing and employee scheduling optimization solutions. Afterwards, they provided clear and…” Read more

Happy clients
We have conducted technical due diligence for investors and companies looking to understand the true state of their technology investments.

Contract management simplified through refactoring, not rewriting
We were the only party advising them to refactor instead of starting over. Over 18 months, we modernised their PHP/Laravel stack, established CI/CD pipelines, migrated infrastructure to DigitalOcean, and dramatically reduced bug rates while mentoring their growing team.

Frequently asked questions
Everything you need to know about our technical due diligence service.
Our standard process is designed to be completed within 10 business days, from the initial interview to the delivery of the final report.
No. A code review is only one part of our comprehensive audit. We also examine the structure of your team, development processes, architecture, infrastructure, security, and scalability.
Yes. Software due diligence, technology due diligence, technical due diligence and tech DD are used interchangeably for the same work: an independent assessment of the codebase, the architecture, the engineering practices and the team behind them. Which term you meet depends on who is running the process. Private equity and corporate development teams tend to say technology due diligence, venture investors more often say technical. In a merger or acquisition it is one workstream among several, sitting alongside financial and legal diligence. The scope is the same whatever your deal checklist calls it.
Our service is designed for both investors seeking to de-risk an investment and for SaaS startups or scale-ups preparing for a funding round, merger, or acquisition.
We operate under strict NDAs and handle all client information with the utmost confidentiality. Any access you provide us with is revoked immediately upon completion.
We deliver a detailed report and conduct a debrief session to ensure all stakeholders understand our findings. We can also join board meetings to present results.
