SAFE Notes in Germany — What Founders Need to Know

Almost every German founder who has spent time in the US ecosystem comes back asking the same question: can we just use a SAFE? The instrument is short, free, well-understood, and signed by email in fifteen minutes. Compared with the German default — a notarised convertible loan with three lawyers in the room — it looks like a gift.

The honest answer is: not really, not the way Y Combinator wrote it. The SAFE was drafted around Delaware corporate law and US securities exemptions. Drop it onto a German GmbH and a handful of structural assumptions break at once. This guide walks through what actually happens, what to use instead, and the narrow situations where a SAFE-shaped instrument can still earn its place in a German cap table.

What a SAFE actually is

A SAFE — Simple Agreement for Future Equity — is the instrument Y Combinator introduced in late 2013 and re-cut as the post-money SAFE in 2018. It is not a loan. It has no maturity, no interest, and no repayment claim. It is a contractual right to receive shares in a future priced round, usually at a discount, a valuation cap, or both. If the priced round never happens, the investor in principle gets nothing back; if there is a liquidity event before conversion, the SAFE pays out at the cap.

That structure is elegant in Delaware because Delaware corporate law lets a company commit to issue future stock with very little ceremony. Authorised but unissued shares sit ready, the board approves issuance at conversion, and the cap table updates. No notary, no court, no minimum capital ritual.

Why German law treats SAFEs differently

The dominant German startup vehicle is the GmbH (Gesellschaft mit beschränkter Haftung) and its smaller sibling the UG (haftungsbeschränkt). Both are governed by the GmbH-Gesetz (GmbHG), and both carry one feature that turns the SAFE on its head: the notarisation requirement.

Under § 15 Abs 3 and Abs 4 GmbHG, the assignment of a GmbH share — and any obligation to assign a GmbH share in the future — must be recorded by a German notary (notarielle Beurkundung). The Bundesgerichtshof has read § 15 Abs 4 broadly: a contractual promise to transfer or to subscribe for a share is itself a transaction that needs notarisation, not just the eventual closing.

A SAFE is, at its core, exactly such a forward promise: in exchange for cash today, the company commits to deliver shares at some future trigger. That promise on a GmbH share, signed on plain paper or DocuSign, sits in a grey zone where many practitioners take the view that it is unenforceable for want of form (formnichtig under § 125 BGB). You can debate the academic question for hours. No founder wants to be the test case.

The capital increase mechanic adds a second layer. In Germany, new GmbH shares are not pulled from a pool of authorised stock the way they are in Delaware. Each capital increase (Kapitalerhöhung) requires a shareholder resolution recorded by a notary, an amendment to the articles, and registration with the commercial register (Handelsregister). At conversion, the company has to actually walk that process. Wrapping the future shares in a SAFE does not skip any of it.

The notarisation problem in plain numbers

Notarial fees in Germany are set by the GNotKG and scale with transaction value. For a typical seed-stage SAFE of, say, EUR 250,000 with a EUR 5,000,000 cap, the notarisation cost is not symbolic — it is the kind of expense that comes in materially higher than the legal cost of the equivalent US SAFE, and it has to be paid each time the instrument or its conversion is recorded. Add lawyer time on top and the "free, fifteen-minute" promise of the SAFE evaporates.

This is not a reason to avoid raising in Germany. It is the reason German practice converged on a different instrument.

The Wandeldarlehen — Germany's working alternative

The instrument German founders and angels actually use is the Wandeldarlehen: a convertible loan with a conversion right. Structurally:

• It is a loan (Darlehen) under §§ 488 ff. BGB, with a principal amount, a (usually low or 0%) interest rate, and a maturity date.
• It carries a conversion right that triggers on a qualified financing, on maturity, or on an exit.
• The conversion mechanics — discount, valuation cap, most-favoured-nation — mirror SAFE economics closely enough that the cap table outcome is broadly the same.
• The loan agreement itself does not require notarisation, because it is a debt instrument, not an obligation to transfer GmbH shares. The notarial step happens later, at the capital increase that converts the loan.

That last point is the structural unlock. By framing the instrument as debt with an option to convert rather than as a forward equity commitment, the parties stay outside § 15 GmbHG until the actual capital increase. The notary appears once, when shares are genuinely issued, instead of twice.

Typical Wandeldarlehen terms

A standard German seed-stage Wandeldarlehen in 2026 looks roughly like this: principal EUR 50,000–500,000 per investor; interest 0–4% p.a., often deferred and added to the conversion amount; maturity 18–36 months; valuation cap negotiated with the lead; discount of 15–25% on the next priced round; qualified financing threshold typically EUR 1–3 million. Subordination clauses (Rangrücktritt) are common to avoid triggering insolvency obligations at the company level if the balance sheet looks thin.

When a SAFE-shaped instrument can still fit

None of this means a SAFE is impossible in a German context. There are three patterns where founders can still get something close:

1. The "SAFE-style" Wandeldarlehen

You can draft a Wandeldarlehen that economically mimics a post-money SAFE: long maturity (5+ years), 0% interest, post-money cap mechanics, no repayment expectation, and conversion-only exit rights. The label says "loan", the substance says "SAFE", and the form requirements stay manageable. Most German venture firms accept this hybrid without much pushback.

2. AG and SE structures

If the company is an Aktiengesellschaft (AG) or Societas Europaea (SE) rather than a GmbH, share transfers are not subject to § 15 GmbHG. AGs can issue authorised capital (genehmigtes Kapital, § 202 AktG) and conditional capital (bedingtes Kapital, § 192 AktG) in advance, which is closer to the Delaware model. A genuine SAFE is still unusual in AG practice, but the structural blockers are weaker. The trade-off is that operating an AG is meaningfully heavier — supervisory board, formal accounts, higher minimum capital (EUR 50,000) — so very few seed-stage German startups choose this path.

3. The Delaware flip

Founders raising primarily from US investors sometimes set up a Delaware C-corp parent above the German operating GmbH. The SAFE is then issued by the Delaware parent, where it works as designed. This is an effective answer for international rounds, but it is a meaningful structural decision with tax, IP, and exit implications, and not a tool to reach for casually mid-raise.

SAFE vs Wandeldarlehen vs KISS — side by side

Tax and accounting — the bits founders forget

A Wandeldarlehen sits on the German balance sheet as a liability (Verbindlichkeit) until conversion. Interest, even if deferred and capitalised, is in principle deductible at the company level under § 4 EStG, subject to the interest-barrier rule (Zinsschranke, § 4h EStG) for larger groups. At conversion, the loan is contributed into equity (Sacheinlage), and the difference between principal-plus-interest and the par value of the new shares lands in the capital reserve (Kapitalrücklage).

For investors, gains realised on conversion or on later sale of the converted shares typically fall under the Abgeltungsteuer regime for private investors (currently 25% plus solidarity surcharge plus, where applicable, church tax), with possible benefits under the Teileinkünfteverfahren for shareholders holding at least 1%. The tax treatment of a SAFE — which is neither clearly equity nor clearly debt under German categories — is far less settled and tends to provoke long memos from advisers.

The practical takeaway: tax certainty alone is a strong reason to stay with the Wandeldarlehen pattern in Germany. You buy a known answer instead of a defensible one.

Prospectus rules and the EUR 8 million ceiling

Whether a Wandeldarlehen or SAFE-style instrument requires a prospectus depends on whether it qualifies as a Wertpapier (security) under the EU Prospectus Regulation (Regulation (EU) 2017/1129) or as a Vermögensanlage under the German Vermögensanlagengesetz (VermAnlG).

The headline thresholds founders should know: under Article 1(3) of Regulation (EU) 2017/1129, an offer of securities to the public with a total consideration in the EU below EUR 1,000,000 over twelve months is exempt; Germany has used the optional national uplift to extend this to EUR 8,000,000 for offers exclusively in Germany under § 3 Abs 2 WpPG (in conjunction with the German implementing rules). Convertible loans that fall under the VermAnlG benefit from a separate exemption regime under § 2a VermAnlG (Schwarmfinanzierung / crowdfunding) up to EUR 6,000,000, subject to per-investor limits.

For a normal seed round of EUR 250k–2m placed with professional or semi-professional angels, none of these thresholds will bite, but the form of the instrument changes which exemption you rely on. Get this categorisation wrong and the instrument can be an unauthorised public offer — a regulatory mess no one needs.

What good German practice looks like in 2026

The pattern that has settled across DACH seed rounds is roughly: a single Wandeldarlehen template, adjusted only on cap, discount, and maturity per investor; subordination by default; conversion at the next round above a defined qualified-financing threshold; signing electronically (the loan does not require notarial form); a notarised capital increase at conversion that bundles all converting investors into one shareholder resolution. That last bundling step is what keeps notarial costs from compounding linearly in the number of investors.

For founders who want SAFE-style speed, the lever is the template, not the legal form. A pre-negotiated Wandeldarlehen with locked terms, signed electronically, can move at SAFE pace. The Anglo-American label is not the thing doing the work; the standardisation is.

Key takeaways

• The YC SAFE was drafted around Delaware corporate law. On a German GmbH it collides with § 15 GmbHG and the German capital-increase mechanic, and is widely treated as form-defective.
• The German market default is the Wandeldarlehen — a loan with conversion right that mirrors SAFE economics while staying outside the GmbH notarisation trap until the actual capital increase.
• If you genuinely need a SAFE, the realistic routes are an AG/SE structure, a Delaware parent above the German operating company, or a SAFE-styled Wandeldarlehen that copies the economics under a German legal label.
• Tax treatment of a Wandeldarlehen is settled; tax treatment of a literal SAFE in Germany is not. That alone is usually decisive.
• Exemption thresholds — EUR 1m / EUR 8m under Regulation (EU) 2017/1129 and § 3 WpPG, EUR 6m under § 2a VermAnlG — are generous enough for a typical seed round, but the categorisation of the instrument decides which exemption applies.
• Speed in a German seed comes from a hardened template and one consolidated capital increase at conversion, not from importing a US-shaped instrument that the local form requirements were never designed to accept.
