French Tech Visa for Founders without an Incubator: the 2-Letters-of-Support Route
Founders without an incubator can apply for the French Tech Visa — officially the Talent permit for porteur de projet économique innovant — using two ecosystem support letters instead. DRIEETS Île-de-France accepts this configuration under Article L421-16 CESEDA, but practitioners consistently report a higher rejection rate on the two-letter route than the incubator path. Letter quality and signer credentials are the decisive variables.
The French Tech Visa for Founders — the Talent residence permit for porteur de projet économique innovant under Article L421-16 of CESEDA — does not require incubator membership. Founders who cannot obtain an incubator support letter can substitute two letters from qualifying ecosystem actors: research organisations, public laboratories, accredited higher education institutions, major enterprises, or “qualified personalities” (personnalités qualifiées) with recognised standing in the French tech ecosystem. DRIEETS Île-de-France accepts this configuration, but practitioners consistently report a higher certification-refusal rate on the two-letter route compared to the incubator path. The variable is not the route itself — it is letter quality. A well-prepared letter from a clearly credentialled signer is treated equivalently to an incubator endorsement; a generic letter from a borderline signer triggers DRIEETS requests for additional information or refusal.
Why the incubator route is the default — and why it isn’t always possible
Most online guides assume incubator sponsorship because it provides built-in institutional credibility. A French Tech–labelled incubator or BPI France–endorsed accelerator has already evaluated the project, so DRIEETS treats the letter as professional certification rather than individual opinion. The practical problem is access: gaining entry to a competitive French incubator programme (Station F, Wilco, NUMA, TheFamily) typically takes two to four months of applications, interviews, and cohort acceptance. Founders who are already operating, already generating revenue, and have no structural reason to join a startup school are not well-served by a process designed for early-stage teams seeking mentorship.
The two-letters route exists for this profile: founders who have real traction, existing sector relationships in France, and a project that speaks for itself — but who haven’t gone through a formal incubator selection process.
The legal basis: Article L421-16 CESEDA
The relevant provision is Article L421-16 of the Code de l’entrée et du séjour des étrangers et du droit d’asile, in the consolidated version introduced by Loi 2024-42 of 26 January 2024 (Loi Darmanin), which abrogated the former L421-17 and rolled the porteur de projet category into L421-16. The permit — officially talent — porteur de projet since Decree 2025-539 of 13 June 2025 — requires certification that the project qualifies as innovative and contributes to the French economy. That certification can come from:
- A recognised incubator or accelerator affiliated with the French Tech network, or
- A research organisation, public laboratory, accredited higher education institution, or major enterprise, or two qualified personalities (personnalités qualifiées) who can attest to the project’s innovative character and economic relevance to France.
Option 2 is the two-letters route. DRIEETS does not publish a pre-approved list of signatories for option 2. It evaluates each signer’s authority on a case-by-case basis, which is why signer selection is the highest-risk step in this route.
Who qualifies as a letter writer
Research and academic sector
CNRS, INSERM, CEA, and INRAE researchers whose domain intersects the applicant’s technology are strong signatories. Professors at Grandes Écoles (École Polytechnique, HEC Paris, ESSEC, CentraleSupélec) or research universities with publication records relevant to the project sector carry weight. Public laboratory directors are accepted when the project has clear scientific or technical overlap with their lab’s mandate.
Corporate sector
Innovation directors, R&D executives, or programme leads at established French companies — particularly CAC 40 and SBF 120 constituents — are accepted when their role gives them specific authority to evaluate technology or market innovation. A generic HR or partnership letter from a large company does not qualify. The signer must be the person who actually works in the domain the founder operates in.
Qualified personalities (personnalités qualifiées)
This is the most flexible category but also the most scrutinised. Accepted signatories in this category include:
- Founders of successful French tech companies with public profiles (previous exits, significant venture-backed businesses) who can credibly evaluate the innovation angle
- Managing partners or general partners at established French venture capital firms — Partech, Eurazeo (formerly Idinvest), Elaia Partners, Kima Ventures, Daphni — who have evaluated companies in the applicant’s sector
- Board members or officers of France Digitale, La French Tech network committees, or similar recognised industry bodies with demonstrable public-sector engagement
What does not work as a signer: generic endorsements from business contacts with no public standing in innovation; letters from international companies unless the individual signer has recognised authority within the French ecosystem; letters from individuals who cannot document their own credentials in writing.
What DRIEETS looks for in a support letter
DRIEETS is not evaluating a character reference. It is evaluating a professional certification of two things: (1) the project’s innovative character, and (2) the signer’s authority to make that assessment.
A letter that passes DRIEETS review consistently contains:
Signer credentials (opening paragraph). Full name, title, institutional affiliation, and two to three sentences on the signer’s domain expertise. For a personnalité qualifiée, this paragraph establishes standing — it must be specific enough that a DRIEETS evaluator unfamiliar with the person can verify the credentials independently.
Context of how the signer knows the project (second paragraph). Specific interaction: “I reviewed the applicant’s technical documentation in January 2026,” “We met at the AI Regulation conference in Paris in March 2026 and I subsequently reviewed the product demo,” “The applicant participated in our accelerator screening process.” Vague phrases like “I have followed their work” or “I am familiar with their company” are insufficient.
Technical innovation description (core of the letter). This is where most letters fail. The signer must describe why the project qualifies as innovative — not in marketing terms but in technical or business-model terms. “The applicant has developed a generative-AI-based supplier risk scoring system that uses proprietary training data unavailable to existing procurement software vendors” is the right register. “The applicant has an innovative AI company” is not. DRIEETS evaluators read dozens of dossiers — they will not infer innovation from a generic sector description.
Explicit endorsement. A clear sentence: “I support [name]‘s application for the talent — porteur de projet permit under Article L421-16 CESEDA. I believe this project meets the criteria for recognition as an innovative economic project and will contribute to the French tech ecosystem.” The phrasing should mirror the statutory language.
Professional contact and signature. Official letterhead, the signer’s professional email and phone number, wet or digital signature consistent with the institution’s standard.
Length: one to two pages per letter. Shorter can look dismissive. Longer than two pages often signals the writer is compensating for weak substantive standing.

The most common failure modes
A letter from a well-positioned contact writing about the wrong thing. An innovation director at a major bank writes that the applicant “is a talented entrepreneur with a promising product.” The signer is credible in principle but has written a character reference, not an innovation certification. DRIEETS returns a motif that the letter does not describe the innovative character of the project.
A letter from a marginal signer writing a strong letter. A startup community manager at a co-working space writes a detailed, technically credible endorsement. The content is good; the signer’s authority is not. DRIEETS may reject on the grounds that the letter writer is not a personnalité qualifiée for this sector.
Two letters that together would be strong but each individually is weak. DRIEETS evaluates each letter independently. One strong letter and one weak letter is not equivalent to two adequate letters — the weak one is still a weak one.
The pattern that emerges from DRIEETS feedback: letter quality is high-variance, which is why practitioners report higher refusal rates on the two-letter route than the incubator route. The incubator path uses a standard letter format that most accredited incubators have already refined through repeated DRIEETS submissions. The two-letter path requires the applicant (or their representative) to actively manage letter quality — which most self-prepared filers underestimate.
Comparing the two routes
| Incubator route | Two-letters route | |
|---|---|---|
| DRIEETS acceptance rate | Higher (institutional standard) | Lower (letter quality varies) |
| Time to prepare | 2–4 months (incubator admission) | 2–6 weeks if signatories cooperate |
| Ongoing commitment | Incubator involvement typically expected | None after the letter is submitted |
| Best fit | Pre-revenue founders wanting ecosystem access | Operating founders with existing sector relationships |
| Cost | Incubator fee (€0 to €10K+/year depending on programme) | No direct fee; time cost to source and brief signatories |
When to choose each route
Choose the incubator route if you are early-stage and would benefit from the mentorship, network, and structured support an incubator provides; you have time (two to four months minimum for admission); or you have been previously refused on the letters route and need stronger institutional backing.
Choose the two-letters route if you are already operating, have clients, and incubator participation would be purely administrative; you have existing professional relationships with qualifying French ecosystem actors; speed matters and you can move faster through letters than through incubator admission; or your sector is narrow enough that a domain-specific research institution or VC firm’s endorsement carries more weight than a generalist incubator.
The borderline case: if your only accessible signatories are from large organisations outside your direct sector, consider whether their authority over your technology domain is demonstrable. A weak letter is worse than no letter — it gives DRIEETS grounds to question whether your project has genuine ecosystem recognition. In this case, spending two extra months to secure incubator admission may produce a stronger dossier overall.
