Until you open the box, deep tech is a black box. Groundbreaking science and sophisticated science fiction look identical — and a single technical oversight can wipe out an entire investment.
Groundbreaking science and sophisticated science fiction look remarkably similar from the outside. Traditional due diligence tools each miss critical dimensions of the picture.
We give you the technical clarity to act with confidence — whether you are making an investment decision, strengthening a portfolio company, or preparing your team.
A technical due diligence that only looks at code misses the full picture. We evaluate all three dimensions that determine whether a deep tech startup will actually succeed.
What the methods, code, data, and results actually mean. Is the approach defensible? Is the architecture scalable? Do the claims hold up under independent scrutiny?
How the technology can solve real problems and create commercial value. Does it address the stated use case? Could it be applied elsewhere or sold as separate products?
Skillset, team cohesion, and transparency. Have key people left? Is the team capable of executing the roadmap? Are they being straight with you?
Other approaches either lack technical rigour or lack commercial context. We sit at the intersection of both — which is exactly where deep tech investment decisions live.
Every stage demands different depth. We calibrate our approach, timeline, and deliverables to match where you are in the investment lifecycle.
Every audit is led by a domain-specific expert — someone who has published in, built in, or led teams within the exact technology being assessed.

"Outstanding performance."
Technical due diligence is our core offering — but our experts cover a wider range of needs for investors, corporates, and technology teams.
Expert-led sessions that give investment teams, boards, and executives genuine working knowledge of deep tech — so they can ask sharper questions and make better decisions.
Targeted assessments for specific technical risks that go beyond a standard due diligence — for when you need depth in one dimension, not breadth across three.
Domain-specific assessments for sectors where regulatory complexity, clinical validity, and technical risk intersect in ways that general technology due diligence cannot fully address.
Eight domain clusters. The specific, named risks that appear most often in deep tech deals — and that standard financial due diligence consistently misses. This is what our experts are trained to find.
For each risk identified, we assess its severity in the context of the specific deal — distinguishing a hard red flag that warrants walking away from a manageable issue that can be mitigated with targeted fixes, contractual protections, or post-investment remediation. Every finding comes with a clear recommendation: block, negotiate, or remedy.
Identifying these risks is exactly our job. Tell us about your deal and we will tell you what to look for.
Brief Us on Your DealStill unsure? Reach out directly — we are happy to scope your engagement before you commit to anything.
Send an email →Technical due diligence is a structured expert assessment of a startup's technology — covering IP defensibility, architecture, scalability, team capability, and the validity of technical claims. For deep tech investments it is essential: groundbreaking science and sophisticated science fiction look deceptively similar, and a single oversight can wipe out an investment.
Pre-seed engagements can be completed same-day. Seed to Series A typically take two weeks. Growth-stage assessments run three weeks. M&A engagements are scoped individually. If you have a hard deadline, tell us — we accommodate urgent timelines.
You receive a structured SWOT report covering defensibility, scalability, and claims verification, plus a competitive benchmark. For technical audits, the report adds a prioritised action roadmap. We also debrief you after each call. You are welcome to attend all calls with the startup team.
When you brief us, we review the technology and identify an expert with direct hands-on experience in that specific field — not adjacent knowledge. For deals spanning multiple domains, we deploy a multi-expert team.
Yes. Our Technical Audit service is designed for startups and their investors who want a concrete roadmap to make the technology more defensible and scalable. It delivers the same SWOT analysis as a due diligence, plus specific action points.
Absolutely. All engagements are governed by an NDA before any information is shared. Our domain experts are bound by the same confidentiality obligations. We have extensive experience operating within strict VC confidentiality requirements.
We offer expert-led masterclasses on AI, Cybersecurity, and Quantum Computing to help investment teams, boards, and LP audiences build genuine working knowledge of deep tech. If you need your team to ask smarter questions of founders, a masterclass with one of our domain experts is the most efficient path.
