SeedLegals was founded in London in 2016 by Anthony Rose and Laurent Laffy. It reports 60,000 registered startups and investors, more than 2,300 funding rounds completed and €2 billion invested through the platform (seedlegals.com, "Our mission" page). On Trustpilot, the company holds a 4.8 out of 5 rating from 1,030 reviews, 93% of them five stars (fr.trustpilot.com, checked on September 15, 2026).
The French version runs from a single online account. You can manage your cap table, issue BSA Air and BSPCE, prepare the paperwork for a funding round and reach a legal expert by chat. This review covers what the platform does, what it costs, and how issuing a BSA Air works step by step, based on the documentation SeedLegals publishes.
What SeedLegals offers
SeedLegals sells annual subscriptions to startups and investors so they can draft, sign and store their legal documents without hiring a law firm for every transaction. You fill in a questionnaire, the platform generates the documents, you get them signed electronically, and they stay stored in your account.
Main features
A SeedLegals account brings together four building blocks:
- the cap table, updated with every transaction (share issue, share transfer, BSPCE exercise);
- customizable contract templates: shareholders' agreement, BSA Air, term sheet, employment and service contracts;
- built-in e-signature, so you can finalize a document without printing anything;
- a data room for sharing documents with your investors.
A SeedLegals legal expert answers questions by chat on the Standard plan, with unlimited access on the Funding plan (pricing page). This support covers how to use the platform and what the terms mean. For a complex negotiation or a dispute, you still need a lawyer.
User interface
Each document is built through a step-by-step form. SeedLegals asks the questions in order, explains each term as it comes up, then generates the document. The dashboard lists your open processes and how far along each one is. The Standard plan includes an online course of around fifty videos (pricing page), and the help center is available in both French and English, which matters if one of your investors doesn't read French.
SeedLegals credits its in-house legal experts with drafting its templates and reports more than 2,300 funding rounds completed on the platform ("Our mission" page). That volume is the main assurance you're paying for: documents that French investors have already signed thousands of times.
Pitching and investor introductions
The Funding plan gives you access to a database of more than 400 investors and covers all the paperwork for a round: term sheet, BSA Air agreements, founder agreements and unlimited share transfers. SeedLegals waives fees on the first €10,000 raised, then charges closing fees on top of the subscription (pricing page).
One tier up, the Roadshow & Pitch offer (priced on quote) adds a fundraising strategy, a tailored investor list, qualified introductions, pitch coaching, monthly pitch sessions in front of investors, access to lawyers at preferential rates and partner perks (AWS, HubSpot and Stripe, among others), again according to the pricing page.
SeedLegals won't build your deck for you, so you'll still need a presentation tool. Our guide on how to build a winning pitch deck covers that part.
Setting up a BSA Air
The BSA Air is France's fast-track investment contract: the investor pays in the funds now and receives shares at the next funding round, at a discount. On SeedLegals, you issue it from the "Financement" tab, using the "BSA Air" card, in eight steps described in the help center.
Documentation process
Here are the eight steps from the help center: create the BSA Air group; fill in the key terms; generate the president's report and the unanimous shareholder resolutions; create the fast-track investment agreement and share it with the investor; sign the report and the resolutions; sign and share the agreement, the subscription form and the president's decisions; close the BSA Air; close the group and sign the president's supplementary report.
In step 2 you set the key terms: the valuation cap, the floor, the discount and the long-stop date. On rounds under €150,000, SeedLegals sees an average discount of 18 to 20%. Above €150,000, it drops to 15%, and 6% of startups offer no discount at all (SeedLegals, BSA Air guide). In the vast majority of cases, the long-stop date falls around 24 months after signing (investor help center).
The payment deadline governs everything else. The investor has 30 days after signing the fast-track investment agreement to transfer the funds and sign the subscription form. After that, the agreement lapses (investor help center).
Conversion and legal support
The BSA Air converts into shares at the first qualifying funding round, or on an IPO, a dissolution or liquidation, or a change of control of the company. If none of these happens, it converts on the long-stop date (investor help center). The SeedLegals legal expert helps you set the cap and floor, but the negotiation with the investor is up to you. Our guide to negotiating a BSA Air gives you the typical ranges and scripts.
How SeedLegals compares
In the French market, three names come up when you look for an alternative.
Alternatives in France
Legalstart reports more than 900,000 entrepreneurs served since 2014 (legalstart.fr) and focuses on company formation and administrative filings. LegalPlace reports more than 300,000 and also sells business address services (legalplace.fr). In 2025, LegalPlace announced a €70 million raise and the acquisition of Legalstart (Infonet). Captain Contrat, for its part, connects you with lawyers for custom contracts.
None of the three builds its offer around fundraising, whereas SeedLegals ties together the cap table, BSA Air, term sheet and investor database in one account. For setting up a company or getting a registered business address, Legalstart and LegalPlace are the better fit.
Strengths and limitations
The strengths show in the published figures: 4.8 out of 5 on Trustpilot from 1,030 reviews, 2,300 funding rounds completed on the platform, and a legal expert on chat included in the subscription.
The main limitation is the entry price. The Funding plan costs €1,250 per year excluding VAT, plus closing fees. The Standard plan, which doesn't cover fundraising, costs €675 per year excluding VAT (pricing page, checked on September 15, 2026). If you only have one transaction in the year, compare that with a specialist lawyer, whom our complete BSA Air guide puts at €1,500 to €5,000 per document. The subscription pays for itself from the second transaction onward.
Features specific to French startups
SeedLegals France handles instruments unique to French law: BSA Air, BSPCE, BSA Advisor and unanimous shareholder resolutions. The Options plan, at €1,990 per year excluding VAT, covers unlimited BSPCE and BSA Advisor creation, option pool management and a dashboard for each beneficiary (pricing page).
If you're preparing a first BSA Air round and want feedback from founders before you sign, apply to swanbase: long-term support for founders, €0, by application, and swanbase takes equity.

Can SeedLegals replace a lawyer?

30 days after signing the fast-track investment agreement. If the funds haven't been transferred and the subscription form hasn't been signed by then, the agreement lapses (SeedLegals help center).

4.8 out of 5 from 1,030 reviews, 93% of them five stars, on fr.trustpilot.com as of September 15, 2026.
What are the French alternatives to SeedLegals?
Legalstart and LegalPlace for company formation and administrative filings, and Captain Contrat for custom contracts drafted with a lawyer. None of the three builds its offer around fundraising.
