SHA Key Clauses for German Startups: What Matters in Your First Round

A German first-round legal package splits into two documents that do different jobs. The notarised Satzung (articles of association) sits in the commercial register and binds the world. The SHA (Gesellschaftervereinbarung) sits between the shareholders themselves and binds them as a contract. Investors push the heavy mechanics into the SHA because it is faster to amend and cheaper to notarise, and most German VCs have stopped trying to fit liquidation preference and drag-along into the Satzung.

The substance is what determines whether you sign a founder-friendly round or a structurally hostile one. Below are the clauses that actually move the needle in a German pre-seed or seed.

What sits next to the Satzung, and why

The SHA does not replace the Satzung; it operates in parallel. Three reasons matter for founders:

The Satzung must be notarised under § 15 GmbHG and § 53 GmbHG, so any change touches a notary appointment, a shareholder resolution, and a registry filing. The SHA can be amended by signed counterparts. That speed gap is why investors front-load the SHA.

Some shareholder rights cannot be moved into the SHA. § 51a GmbHG grants every shareholder information and inspection rights, and § 51a (3) GmbHG explicitly forbids restricting them in the Satzung. The prevailing view in the leading commentaries (Baumbach/Hueck; Scholz, GmbHG) is that the right is effectively non-waivable, and SHA constructs that try to dilute it are exposed to challenge. Investor reporting in the SHA stacks on top of § 51a; it does not replace it.

The voting and exclusion rules in the SHA are tested against § 138 (1) BGB (good-morals invalidity). The BGH Hinauskündigung jurisprudence (II ZR 173/04 of 19.09.2005, "Managermodell"; II ZR 342/03 of the same date, "Mitarbeitermodell"; II ZR 281/05 of 07.05.2007) applies to vesting, leaver clauses, and drag-along by analogy. A clause that lets a majority eject a co-shareholder without an objective justification is void.

The four control clauses

Vesting and leaver mechanics are the longest negotiation in most rounds. Four-year reverse vesting with a one-year cliff is the German market default, with good-leaver and bad-leaver definitions allocated to specific facts. After BAG 19.03.2025 (10 AZR 67/24), bad-leaver forfeiture of vested shares is contestable as an unreasonable AGB term; the vesting and bad-leaver article covers the redraft architecture in detail.

Information rights split into two layers. § 51a GmbHG sits underneath as a non-waivable floor. On top of that, the SHA usually grants the lead investor monthly KPI reports, quarterly financial statements, and an annual audited account. Founders should resist mid-month observer demands and any clause that treats § 51a-style requests as restricted by the SHA's reporting cadence.

Reserved matters (Zustimmungsvorbehalte) are where investor control compounds. A typical pre-seed list includes budget, hiring above a threshold, debt above a threshold, related-party transactions, IP transfers, and any new financing round. The Beck'sches VC-Handbuch (Bank/Schaper/Ullrich/Ahlert) treats this list as the most-frequently-overdrafted clause in German seed practice. Founders should push back on day-to-day operational items and limit the trigger to material decisions.

Founder lock-up and transfer restrictions usually apply to the founders only, not to investors. Reichert/Walz in the Beck'sches Formularbuch flag this asymmetry as standard but recommend an exit-trigger or sunset.

The four exit economics clauses

Liquidation preference defines who gets paid first at exit. The German market default in healthy 2026 rounds is 1x non-participating: the investor takes the higher of (a) the original investment back plus accrued amounts, or (b) the pro-rata share of proceeds. CMS, Heuking, and LUTZ|ABEL all report 1x non-participating as the founder-friendly baseline. Participating preferences (the investor takes the preference and shares pro-rata afterwards) appear in down rounds and certain late-stage extensions; treat them as a yellow flag.

Anti-dilution protection adjusts the investor's conversion ratio if a future round prices below the current round. Broad-based weighted-average is the German standard; the formula factors all shares on a fully diluted basis, so the adjustment scales with the size of the down round. Full-ratchet adjusts retroactively to the new price regardless of round size and is, in the words of practitioner literature, "absolutely atypical" for German seed deals. If a term sheet asks for full-ratchet, the round itself is signalling stress.

Drag-along forces a minority to sell when a defined majority decides to exit. The orthodox view applies the BGH Hinauskündigung doctrine by analogy: a drag that effectively expels a minority without an objective justification or temporal limit can be sittenwidrig under § 138 (1) BGB. A counter-current in the literature (Weitnauer; Goette in MüKo-GmbHG) argues that an equal-price drag is not a Hinauskündigung at all, because the minority is not expelled but exited on equal economic terms. Even authors holding that view recommend the same drafting safeguards because litigation risk is asymmetric. The DNotI position is that drag-along clauses survive scrutiny when they include a minimum price, equal economic treatment, and an objective trigger (a third-party bona-fide offer for 100 percent of the shares at a reasonable valuation).

Tag-along is the founder's mirror image of drag. When a majority shareholder sells, minority shareholders can join on the same terms. Most German SHAs include both. Founders should make sure the tag-along covers partial sales (not just full-exits) and is symmetric with drag thresholds.

Where I see this go wrong

Most of the SHAs I review for founders before signing have the same two soft spots. Reserved matters drift into operational territory, and founders end up needing investor sign-off on the kinds of decisions a seed-stage CEO should make weekly. The fix is a thresholded list (e.g. spend over EUR 50,000 per item, not budget overall) with a clear escalation route. The other soft spot is drag-along without a minimum price floor, which puts the entire SHA on shaky § 138 (1) BGB ground if any minority shareholder ever litigates. Adding a fair-market-value floor and a third-party-offer trigger is a fifteen-minute drafting fix that closes most of the BGH risk.

Pro-investor vs. pro-founder defaults

SHA review checklist

Bottom line

The SHA is the document that defines what your round actually does. The German market in 2026 is founder-friendly enough that 1x non-participating, broad-based weighted average, and four-year vesting with one-year cliff are the defensible defaults, and any deviation should be a deliberate trade for something else of value. The BGH Hinauskündigung doctrine (II ZR 173/04, II ZR 281/05) is the legal backstop that makes overly aggressive drag-along and bad-leaver clauses contestable. Pair this checklist with the pre-seed fundraising fachbeitrag for the broader process; if you also have a VSOP pool or a holding structure above the operating GmbH, both interact with the SHA in ways the term sheet rarely spells out.
