Declassified: What a One-Sided Investor NDA Actually Costs
A anonymised case study of a startup that signed an investor NDA with hidden IP and survival traps — and what structured review would have flagged.
Scenario
A seed-stage SaaS founder received a five-page investor NDA before a diligence call. The template looked standard. They signed the same day.
Six months later, a portfolio company in a adjacent space raised concerns about overlapping product direction. The investor's counsel cited broad confidentiality language and a residuals-style exception the founder had not noticed.
Identities and figures are anonymised. The clause patterns are common.
What the template contained
- Unbounded confidentiality — "any information disclosed in connection with the evaluation"
- Residuals language — use of concepts "retained in unaided memory"
- Five-year survival after termination
- Delaware exclusive jurisdiction (founder based in the EU)
Estimated Burn Score if reviewed today: 72 (critical).
What negotiation achieved
After counsel involvement (cost: several thousand euros):
- Confidentiality limited to marked materials and diligence dataroom content
- Residuals clause removed
- Survival reduced to three years
- Jurisdiction moved to founder's EU member state
What structured AI review would have shown
Uploading the original PDF to NDAShield would have flagged:
- Critical: residuals + broad definition combination
- High: survival period vs industry norm
- High: jurisdiction mismatch

Lesson
Investor NDAs are not ceremonial. Run clause glossary checks on unfamiliar terms before you sign.
