Case Studies
From Hype to Red Flag
Situation
An investor syndicate approached us with an early-stage deeptech opportunity. Our role: examine the deal structure and documentation, achieve clarity, and support due diligence around a EUR 300k+ decision
Our Role
- Reviewed the full investor deck, SHA, financial projections, and technical roadmap
- Engaged with the founding team and advisors
- Recorded project maturity, governance, risks
- Produced a fast-turnaround red-flag report highlighting objective risks
Outcome
Red-flag report showed a concentration of structural and behavioral risks, and gave the investor syndicate the clarity required for their ultimate investment decision.
From $25M Dream to $10M Reality
Situation
A founder team building a GPT-based tool sought feedback on their deck and fundraising plan. The seeked valuation was too high for the product and market and the deck was quite messy.
Our Role
- Flagged inflated TAM and inaccurate client positioning
- Repositioned valuation logic and go-to-market story
- Shared benchmarks for AI pitch expectations
Outcome
Though not formally engaged, the founders implemented our feedback - revised their valuation ask to $10M and materially improved pitch credibility - resulting in succesful funding of their pre-seed round.
Let’s talk about your due diligence.

Request a consultationWhy We Do This
Npercent was built to answer a problem we kept seeing on both sides of the table: founders struggle to position themselves credibly, and investors lack the time or context to cut through the noise - especially in the day where everyone can make fancy slides.
What sets us apart is how we combine perspectives. Jean's deep technical knowledge breaks down technical claims and product narratives - not just at face value, but by stress-testing what’s under the hood. Alberto’s decades-long experience in buy-side finance interrogates financial assumptions, strategic market logic, and structuring coherence with an investor’s eye.
We don’t stop at “nice deck” or “strong team.” We ask: does the data hold up? Does the story make sense in this market? Are the numbers structured to support a raise - or just to impress?
Our clients don’t come to us for cheerleading. They come to avoid wasting time, missing red flags, or walking into a raise that’s dead on arrival. We work fast, we go deep, and we tell you what others won’t.
We believe no ticket size is too small for proper due diligence: whether it’s 20 thousand or 2 million, you deserve to know what your money is buying.
