Case Studies

From Hype to Red Flag

Situation

An investor syndicate approached us with an early-stage deep-tech opportunity. Our role: act as an intermediary, review the deal structure and documentation, and help decide whether to commit €350K.

Our Role

  • Reviewed the full investor deck, SHA, financials, and technical roadmap
  • Engaged with both the founding team and legal counsel from both sides
  • Assessed maturity, governance, and risk disclosures
  • Produced a 10-page red-flag report and go/no-go summary

Outcome

Despite early interest, we recommended not proceeding with the investment. The signals pointed to structural and behavioral issues that could create downstream risk. Our clarity helped the syndicate avoid potential complications and redirect their focus.

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.

Why 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 finance interrogates financial models, market logic, and strategic 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 20'000 or 2 milion, you deserve to know what your money is buying.
