Investoren-Due-Diligence scheitert regelmässig an ungeklärten IP-Rechten. Ein kryptographischer Zeitstempel löst das Problem in zwei Minuten, bevor es entsteht.
In October 2025, a Geneva-based fintech startup reached the term sheet stage with a Swiss institutional investor. The founding CTO had spent fourteen months building the core algorithm. During due diligence, the investor's legal team asked for a verifiable development timeline. Three contractors had contributed code during the prototype phase. None had signed work-for-hire agreements. No qualified timestamps existed on any early commits. Due diligence stalled for six weeks. The final term sheet came back with a 20% valuation discount.
This is not an edge case. It is the most common preventable mistake in Swiss and European startup financing rounds, and it always follows the same pattern: the IP documentation that would have taken a few minutes per milestone is missing at precisely the moment it is needed most.
Investors now examine IP rights with forensic attention. Four questions dominate every IP audit:
Ownership: Who owns the code, the design, the concept? Freelancers who worked without a clear work-for-hire agreement can assert claims. Founders who brought code from a previous employer can trigger liability.
Creation date: When exactly was the core invention developed? This matters when a competitor launched a similar product shortly before or after.
Documentation: Is there a traceable development path? Commits, revisions, concept sketches with verifiable timestamps?
Litigation risk: Are there potential third-party claims? Without timestamp documentation, the answer is always: possibly.
Swiss ZertES (SR 943.03) and the EU eIDAS Regulation (Art. 41) grant qualified electronic timestamps a legal presumption: the time is presumed correct and the file integrity presumed intact until the contrary is proved.
For a startup, a Swiss Trust Layer timestamp on the first commit of the core algorithm is a first-class piece of evidence before Swiss and EU courts. The opposing party must prove the timestamp is wrong. You do not need to prove it is right.
Swisscom Trust Services, the certification service provider behind Swiss Trust Layer, is both a ZertES-accredited ZDA and an eIDAS QTSP listed on the EU Trust List. One document covers Swiss courts and all 27 EU member states.
Had the founding CTO applied a ZertES-qualified timestamp to each significant commit and each contractor deliverable during the prototype phase, due diligence would have taken days, not weeks. The investor's legal team would have seen a verifiable, court-admissible development timeline. The three contractors' contributions would have been clearly dated and scoped. The 20% valuation discount would not have appeared on the term sheet. The CHF 5 per timestamp would have returned multiples of its cost in valuation preserved.
Not every file needs a timestamp. But the right files must have one:
1. Upload your file: Every format is accepted. The file never leaves your control. Only the cryptographic hash is processed.
2. Receive your timestamp: Swiss Trust Layer transmits the hash through Swisscom Trust Services and receives a ZertES- and eIDAS-compliant timestamp in return.
3. Secure your certificate: You receive a PAdES-compliant certificate with hash, timestamp, issuer, and identity. Store it alongside the original file.
4. Document continuously: Seal at every significant milestone. This creates a version chain that is essential for due diligence processes.
5. Offer validation: Any investor can verify your seals at swisstrustlayer.com/validate, without an account, without login.
The standard for IP due diligence has tightened substantially in recent years. Institutional venture capital, corporate venture arms, and private equity investors now expect structured, traceable IP documentation. It is not an optional extra. It is a condition for a clean transaction.
1. Independent development evidence.
Can the startup demonstrate that the core product was built without using IP from previous employers or third-party sources? Founders from large technology companies face particular scrutiny. Time-stamped development steps from the early phase, before the founding date, are strong evidence of independent development.
2. Clear ownership structure.
Who owns the IP? The company or the founders personally? For investors, it is decisive that IP rights have been formally transferred to the company. Sealed transfer documents with timestamps show when the transfer of ownership occurred.
3. Complete employee and freelancer agreements.
Everyone who contributed to the product should have signed a work-for-hire agreement. Missing or backdated contracts are a frequent deal-breaker. Time-stamped contract versions rule out later disputes over contract content.
4. Traceable patent preparation.
For deep-tech and software IP, investors check whether the startup took early patent preparation steps. Even if no patent is filed, sealed technical descriptions of the core invention approach strengthen the negotiating position against patent trolls and competitors.
5. No unresolved IP disputes.
A pending or potential IP dispute, even if it appears unfounded, is for many investors an immediate stop-loss. A clean IP audit, supported by time-stamped documents, gives investors confidence that no hidden legacy issues exist.
The practical finding: startups that have built their IP documentation proactively and with timestamps complete due diligence processes faster, achieve higher valuations, and negotiate from a position of strength.
Swiss Trust Layer offers Seal Credits Lite from CHF 5 per year. For growing teams, scalable plans are available. The cost of a single timestamp is a fraction of the legal costs an unresolved IP dispute generates. Average Swiss IP disputes cost between CHF 150,000 and CHF 400,000 according to the Swiss Arbitration Association.
"We have everything in GitHub. Is that not sufficient?"
Git commits are modifiable and have no external certification anchor. GitHub logs are not court-admissible evidence. A Swiss Trust Layer timestamp on a repository snapshot, by contrast, is usable in court.
"Our lawyer says NDAs are enough."
NDAs govern confidentiality, not ownership rights. An NDA does not prove when something was developed or who owns it. Timestamps and NDAs complement each other. They do not replace each other.
"We are too early for these processes."
The opposite is true. The earlier you document, the stronger your position. Most IP disputes involve precisely that early phase in which startup teams experiment, hire freelancers, and share ideas with potential partners.
A 20% valuation discount on a Series A round worth CHF 5 million is CHF 1 million. A qualified timestamp on each early commit and each contractor deliverable would have cost under CHF 100. That is the comparison every CTO should make before sharing their first line of code with anyone outside the founding team. Start documenting now: swisstrustlayer.com.

Why the World Needs a Copyright Register Outside the United States
A US Copyright Office filing protects a work only inside the United States. Trademarks and patents got global filing systems years ago. Copyright never did, and that gap is what proof still has to close.
Creators and Photographers: Prove You Made It Before It Gets Scraped
AI crawlers strip metadata in seconds. Sealing an image at export creates a dated, globally recognized record proving you made it, before it turns up in someone else's feed or training set.
The Berne Convention in Plain Terms: You Own It on Creation, So Why Is Proof Still Hard?
Under the Berne Convention, copyright exists automatically the moment you create something, in 181 countries, with no filing required. That right is real. What it does not hand you is a dated record tied to the exact work, and that is what a dispute actually turns on.
Why a US copyright registration does not protect you outside the United States
A US copyright registration is a powerful thing inside one legal system and close to inert outside it. This is why it does not cross the border, what national treatment actually carries with it, and what a European rights holder can rely on instead.
The world has no copyright register, except the United States. Why that matters.
Under the Berne Convention, copyright arises automatically on creation in 181 countries, with no registration required. Almost none of those countries keep a record of it. That gap is invisible until the day somebody disputes who made something first.
