WiSEED is the oldest crowdfunding platform in France, started in Toulouse in 2008. Most of what it sells today is property debt: you lend from EUR 100 to a company set up by a property developer for a single scheme, usually for 12 to 36 months, at a coupon of 8% to 12%, and get your money back with interest at the end.
It also runs a smaller legacy business in startup shares, renewable energy and SME bonds, and distributes property funds and a life insurance contract.
It has raised more than EUR 590 million across roughly 927 projects, with 225,178 registered members but only around 32,600 who have actually invested.
WiSEED holds a French AMF crowdfunding licence, number FP-2023-33, granted on 15 November 2023, alongside an older investment services authorisation.
The important fact for 2026 is that the business itself failed: the operating company was placed in court-supervised rescue on 20 October 2025 and sold to the Advenis group by court order on 11 December 2025.
Advenis does not yet hold the licence in its own name, so the two are operating jointly during a transition.
Anyone over 18 who is not a US resident can invest.
Cash waiting to be invested sits at licensed payment firm Lemonway, but no deposit guarantee or compensation scheme covers what you lend. Investing is free above EUR 1,000.

There are two stages. First WiSEED's 200,000-plus members can question the developer and vote on whether a project should be funded — the feature the platform was built on in 2008. Then an in-house team reviews the developer's finances and the scheme's economics and gives a letter grade from A to E. The grade has been heavily criticised as not predicting much: reviewers point to projects graded A that ended in liquidation, and the scoring method is not published. Reviewers also describe a loss of rigour as volume rose to around ten new projects a month, security that was often a personal guarantee rather than a mortgage, and offer documents missing pre-sales data.
WiSEED was founded in 2008 by Thierry Merquiol and Nicolas Seres in Toulouse. Both are gone from the top. The registered president since 27 February 2026 is Anne Smolen, with Mathilde Iclanzan as managing director since August 2021 — the change of president being the visible result of the takeover. Control now sits with Advenis Wise, a company created on 11 September 2025 to receive the business, run by Rodolphe Manasterski and owned by Advenis SA. Headcount has roughly halved, from about 40 in 2023 to around 20 at the time of the court decision, with about 30 posts preserved in the sale.
Until 2025 WiSEED monitored projects, chased late developers and paid for legal action itself. That changed on 17 April 2025, when it told investors that legal and procedural costs would be theirs: money is set aside up front on new deals from May 2025, and on existing deals WiSEED asks investors for cash to fund litigation, at a stated 4% to 8% of the sum invested. If investors do not pay, no legal action is taken. In practice the bills have run higher — one investor reported being asked for EUR 1,080 on a EUR 2,000 investment. One reviewer reports the policy was reversed after Advenis took over, though this could not be confirmed. There is no safety fund, no buyback and no resale market.
Bonds, including property deals, carry a 0.9% entry fee below EUR 1,000 and nothing at or above that. Startup shares are far more expensive: 0.9% entry below EUR 1,000, 5% management on the total invested, and an exit charge of 10% to 20% of what the vehicle distributes, plus a widely quoted 10% of any gain. Property funds and life insurance carry their own charges. The payment account and withdrawals are free. The cost that actually matters in 2026 is the recovery levy of 4% to 8% of the amount invested on troubled projects. French residents also pay a flat 30% tax made up of 12.8% income tax and 17.2% social charges.
This is the defining fact about WiSEED in 2026 and it is national trade-press coverage, not investor grumbling. The operating company was placed in accelerated court-supervised rescue on 20 October 2025 by the Toulouse commercial court and sold by court order on 11 December 2025 to Advenis; the registered company has since been renamed. Separately, the April 2025 decision to bill investors 4% to 8% of their investment to pay for legal action on projects WiSEED itself chose produced a sustained backlash on French forums, with complaints that no itemised costs were given, that cash calls went out before the bondholder votes meant to approve them, and that amounts diverged from the stated formula. Trustpilot has fallen from 3.8 out of 5 in January 2024 to 2.3 to 2.5 across more than 1,200 reviews. Recurring themes are silence on troubled projects, A-graded projects going into liquidation and rising write-offs. No regulator has sanctioned WiSEED.
The 22.52% is measured by amount on lending that has reached its due date; a separate 6.9% counts projects more than six months late. They are not alternatives and several review sites confuse them. Also keep the context: French property crowdfunding as a whole had a bad 2025, with one project in two showing significant difficulty. WiSEED sits at the worse end of that band rather than outside it — but its realised write-offs of 6.54% are the highest of any French platform.
