BLAST, also called Blast Club, is a French paid-membership club for investing in startups, founded in 2022 and run from Paris by BLAST SAS. You must pay a yearly membership before you can see or join any deal. Blast says its members have invested €300 million since 2023 in more than 250 startups, and that more than 14,000 members have registered (October 2026). The 250 count includes each company in the Y Combinator groups it invests in; independent databases record about 46 to 48 separate investments.
You pick a membership tier, from €1,500 a year (Bronze) to €10,000 (Diamond); the fee cannot be used for investing. You then invest from €500 per deal, up to a limit set by your tier: Bronze allows €2,000 per deal and €10,000 a year, Diamond has no limit. Each deal runs through its own French holding company, so you own shares in that vehicle, not directly in the startup. There are four programmes: young Y Combinator companies (seed and Series A), large late-stage companies before a stock-market listing, and European startups from seed to Series B.
Blast publishes no return for its whole portfolio. It shows target multiples by programme: 10 to 15 times the money over 8 to 10 years for Y Combinator seed deals, 10 to 12 times for Series A, 2 to 5 times for late-stage companies and 3 to 10 times for European startups. These are goals, not results. It also shows selected deals: Groq returned 3.3 times the money (104% a year), Flease 2.6 times (34% a year) and Akka 8 times (exit completed in the first half of 2026), all before fees, taxes and currency effects; Blaxel is valued at 6.8 times on paper. Its home page claims €24 million of "earnings generated by members" (it was €14 million in August 2026), without saying what is counted. Against €300 million invested, that is about 8% in total, not per year, calculated from the platform's own figures.
Blast publishes no figure for failed or written-down companies. Its portfolio page marks three exits and no failures among about 69 named companies. That is not a realistic picture for young startups, where many usually fail. Most of the money was invested in 2025 and 2026, while the stated holding periods are 3 to 10 years, so failures are likely still ahead and cannot be known yet.
Nothing secures your money. You own shares in a holding vehicle that owns a minority stake in a young company, with no collateral, buyback, insurance or compensation scheme; the platform itself warns that the main risk is losing everything you invest. Your voting and information rights are exercised through the vehicle, not directly in the company. Cash waiting to be invested is held by the payment institution Lemonway, not by Blast. Fees already paid are not returned if a company fails.
BLAST SAS (Paris, company number 915 236 640, founded 5 July 2022) is authorised by France's markets regulator, the AMF, as a crowdfunding service provider under the EU crowdfunding rules (no. FP-2023-12, since 21 August 2023), with a passport to Belgium and Luxembourg. It is led by Anthony Bourbon (president) and Samuel Guez (managing director). No public accounts had been filed for the company as of August 2026, although it handles hundreds of millions of euros of members' money. In July 2024 French financial press described one €30 million raise as largely a sale of shares by founders, on which Blast earned a 9% commission. No regulator action is known. Public review score 4.9 out of 5 (2,113 reviews, August 2026).
Fees come in four layers. The yearly membership costs €1,500 to €10,000. Each investment carries a one-off structuring fee of 5% (Bronze and Silver), 4% (Gold and Platinum) or 3% (Diamond). The investment vehicle pays 1% to 2% a year to Blast for 5 to 10 years, depending on the startup. Blast also takes 20% of any gain when shares are sold. For a Bronze member investing €2,000 in the first year, the membership alone is €1,500. Fees on the resale market are not stated.
Usually you cannot get out when you want to. There is no maturity date; money comes back only when the company is sold or listed, or when you sell to another member. Blast runs a members-only resale market for European deals; it says more than €15 million has changed hands there (undated), but it does not promise that you will find a buyer. Shareholder agreements allow resale after five years. Expect to wait 5 to 10 years.
Return: Very High — the targets go up to 15 times the money and some deals have returned 2.6 to 8 times, but no result for the whole portfolio is published. Risk: High (higher means more risk) — no failure figures are published, the track record shows only winners, the headline earnings figure is undefined, and the company files no accounts. Risk-return: Medium — for startup shares we weigh the winners more than the failures, which places it between High risk and Very High return; even if half the companies fail, a portfolio can do well if a few return ten times the money.
License / Regulation: BLAST SAS (Paris, RCS 915 236 640) is authorised by the French Autorité des Marchés Financiers (AMF) as a crowdfunding service provider under Regulation (EU) 2020/1503, no. FP-2023-12, since 21 August 2023, for equity placement through project owners or special purpose vehicles and order transmission, with a passport to Belgium and Luxembourg. No deposit guarantee or investor compensation scheme covers investment losses.
Yes. BLAST SAS is authorised by France's markets regulator, the AMF, as an EU crowdfunding provider (no. FP-2023-12, since 21 August 2023), with a passport to Belgium and Luxembourg. Regulation does not protect you from losing money on a company.
Lemonway, a French payment institution authorised by the ACPR, holds members' money; Blast acts as its agent. Once you invest, your money goes into a holding vehicle for that deal, which buys the startup shares.
€500 per deal, but only after paying a yearly membership of at least €1,500. So the smallest first-year outlay is €2,000.
No portfolio return is published. Selected deals returned 2.6 to 8 times the money before fees (Groq, Flease, Akka), and Blaxel is valued at 6.8 times on paper. No failures or write-downs are published. Most of the €300 million was invested in 2025 and 2026, so results are still years away.
Nothing. You own shares in a holding vehicle with a minority stake in a young company, with no collateral, buyback, insurance or compensation scheme. If the company fails you can lose everything, and fees already paid are not returned.
Only to another member on the members-only resale market, which covers European deals; a buyer is not promised. Shareholder agreements allow resale after five years. Otherwise money comes back only when the company is sold or listed.
A yearly membership of €1,500 to €10,000; a one-off structuring fee of 3% to 5% per investment, by tier; 1% to 2% a year charged to the holding vehicle for 5 to 10 years; and 20% of any gain when shares are sold.
If a company fails, shareholders are paid last and usually get nothing. Your shares are held through a separate vehicle for each deal, not by Blast itself, but no compensation scheme covers losses, and Blast files no public accounts to show its own financial strength.
A figure on the home page, before income tax, without a definition or date; it rose from €14 million in August 2026. Blast does not say whether it counts cash from exits, paper gains or sales between members. Against €300 million invested it is about 8% in total.
