Startup Fundraising in France 2026: Seed, Series A, Term Sheet — Complete Legal Guide

Fundraising is one of the most structuring operations in the life of a startup. Between signing a term sheet, negotiating a shareholders' agreement and finalising a capital increase, each step durably commits governance, dilution and future valuation. This 2026 guide details the applicable French legal framework, the instruments available at each stage (seed, Series A, Series B/C) and the contractual pitfalls to anticipate.

1. General legal framework

Fundraising through a capital increase is governed by Articles L. 225-127 et seq. of the French Commercial Code for joint-stock companies (SA) and L. 227-2 et seq. for simplified joint-stock companies (SAS), now the dominant form in the startup ecosystem. The capital increase requires a collective decision of shareholders, generally by a two-thirds majority or unanimously depending on the bylaws.

The Ordinance of 24 June 2004 liberalised composite securities (BSA, ABSA, CB, OCEANE), allowing sophisticated financial engineering. The PACTE Law of 22 May 2019 further relaxed several regimes (BSPCE, preference shares, vesting), facilitating VC operations.

Key stages of a financing round

Pre-marketing / teaser: solicitation via investment memorandum.
NDA: prerequisite for sensitive information sharing.
Term sheet: non-binding letter of intent (except exclusivity, confidentiality, fees).
Due diligence: legal, tax, social, IP, data audit.
Definitive documentation: SPA, shareholders' agreement, amended bylaws, side letters.
Closing: signing, fund transfer, publicity formalities (BODACC, RCS).

2. Financing stages and their specificities

Stage	Average ticket	Post-money	Typical instruments	Investors
Pre-seed	€100K–500K	€1–3M	BSA Air, SAFE, CN	Angels, family office
Seed	€500K–3M	€3–10M	Preferred, BSA Air	Seed funds, BPI

Series B	€15–40M	€50–200M	Preferred with liquidation preference	Growth funds
Series C+	€40M+	€200M+	Preferred, convertible debt	Late-stage, corporate VC

3. The term sheet: critical clauses

The term sheet crystallises economic and legal terms. Although mostly non-binding under French law, it constitutes the de facto basis for all definitive documentation: any concession at term sheet stage is extremely difficult to renegotiate later.

3.1. Economic terms

Pre-money valuation: determines dilution.
Option pool: reserve for future employees (typically 10–15%), generally created before the round.
Liquidation preference: 1x non-participating is European market standard; avoid participating or multiples.
Anti-dilution: prefer broad-based weighted average over full ratchet.

3.2. Governance terms

Board composition: at Series A, typically 1 investor seat, 2 founders, 1 independent.
Reserved matters / veto rights: budget, key hires, new debt, M&A.
Information rights: monthly/quarterly reporting.

3.3. Exit terms

Drag along: 50–75% threshold to force minority sale.
Tag along: minority co-sale right.
ROFR: pre-emption right.

4. Seed instruments: BSA Air, SAFE, Convertible Notes

The BSA Air replicates the US SAFE: BSA subscribed against immediate payment, converted at next qualified round with discount (15–25%) and valuation cap. SAFE is now used in France despite no specific legal qualification — usually qualified as conditional promise to issue shares. Convertible bonds (Art. L. 228-91 et seq.) combine bond remuneration and equity upside, favoured in bridge or pre-IPO.

5. Due diligence: data room

Classic sections: Corporate (bylaws, K-bis, share register, BSPCE/BSA issued), Contractual (major customer/supplier, leases, SaaS), Social (employment, collective agreements, disputes), IP/Tech (trademarks, patents, source code, IP assignments), Tax (returns, ongoing audits), Compliance (GDPR, AMF, sanctions).

6. Frequent contractual pitfalls

Participating liquidation preference: very unfavourable on moderate exits.
Full ratchet anti-dilution: massive founder dilution.
Founders' vesting too short: 4 years with 1-year cliff is standard.
Poorly defined bad leaver: risk of losing vested shares.
Overly broad investor vetoes: can paralyse management.

7. Recent case law

Cass. com., 22 March 2023, no. 21-22.547: validity of well-drafted drag along clauses in SAS.
Cass. com., 11 January 2023, no. 21-12.582: sanction of manifestly disproportionate bad leaver clause.
CA Paris, 14 February 2024: enforceability against bad faith third parties (complicity of breach).

8. Internal linking

Conclusion

Fundraising is a high-density legal exercise where every term sheet clause conditions the capital trajectory for 5 to 10 years. Specialist VC counsel secures valuation, preserves founder room for manoeuvre and anticipates optimal future exit conditions.
