Important: the company that ran WiSEED became insolvent. It entered court-supervised rescue proceedings on 20 October 2025, and on 11 December 2025 the court approved the sale of the business to Advenis Wise, part of the Advenis group. The crowdfunding licence is still in the name of the old company while the two work together during a transition.
What it is
WiSEED is France's oldest crowdfunding platform, started near Toulouse in 2008. Most of what it has sold is property debt: bonds issued by companies that developers set up for a single building project. It also offered shares in startups, renewable energy projects and business bonds, and distributes property funds. The home page shows more than €590 million raised since 2008 (October 2026). New lending has almost stopped: €65.0 million was raised for debt projects in 2022, €11.1 million in 2025 and under €1 million so far in 2026 (as of 14 October 2026).
How it works
You invest from €100 per project. In a property bond you lend to the project company for a fixed term at a fixed rate and are repaid, with interest, when the homes are sold or refinanced. In a startup you buy shares, usually held through a holding company, and wait five to eight years or more for a sale. You choose each project yourself.
Returns
The debt projects funded since 2013 carry an average interest rate of 9.52% a year, weighted by amount (as of 14 October 2026). That is the rate in the contracts, not what investors received after delays and losses. The home page advertises returns of up to 12%. Interest actually paid since 2013 comes to €53.8 million on €418.2 million lent. A figure of 7.42% a year after fees and before tax (30 June 2026) is quoted for WiSEED elsewhere, but we did not find it on the platform's own pages, and it is not clear whether losses are taken off. With the losses below, the real return is well under 9.52%.
Losses and defaults
Losses are high and still rising. By 14 October 2026, 7.93% of all the money lent since 2013 had been lost for good on 79 projects, up from 6.54% in July 2026 (calculated from the platform's own figures). Counting money in serious trouble as well, 22.77% of all money lent was lost, more than six months late, or tied up in insolvency or settlement proceedings with the developer (€95.2 million of €418.2 million, calculated from the platform's own figures). WiSEED counts a project as in default when it is more than six months late or in such proceedings. Delays are common: about two in three projects that have been fully repaid were repaid late. Startup shares are not in these figures; the statistics page lists 62 startup investments that ended at a loss (October 2026).
What secures your money
Each property bond has its own security, which depends on the deal: often a guarantee from the developer or its parent company, a pledge on the shares of the project company, and sometimes a mortgage. The platform publishes no overview of the security across its loans. There is no buyback, reserve fund or insurance. When projects have failed, the security has not brought back much: on the failed projects closed so far, investors got back about 22% of their capital (calculated from the platform's own figures, July 2026). Since April 2025 investors have been asked to pay the legal costs of chasing failed borrowers, stated at 4% to 8% of the sum invested. Startup shares are not secured at all: if the company fails, the shares are usually worth nothing, and no compensation scheme covers them. In plain words, your money depends on each developer finishing and selling its homes.
Who runs it and its licence
The licence holder is WiSEED SA (company number 504 355 520, near Toulouse), since renamed "37500 WISEED" on the French company register. It made a net loss of €2.3 million in 2024 on revenue of €5.36 million. After the court-ordered sale of 11 December 2025, the business is run with Advenis Wise (company number 991 268 012, Paris), owned by Advenis SA. The French market regulator (AMF) granted WiSEED a European crowdfunding licence, number FP-2023-33, on 15 November 2023; the register still showed it in force in August 2026, with no Advenis company holding its own licence. Your bonds are claims on the project companies, not on WiSEED, so its insolvency does not cancel them, but it changes who manages them.
Fees
The payment account and withdrawals are free. Entry fees on bonds and charges on startup shares are set out on WiSEED's help pages; we could not confirm the current amounts for this update. The cost that matters most now is the legal recovery charge on troubled projects, stated at 4% to 8% of the amount invested.
Getting your money out
WiSEED states that bonds cannot be sold or repaid early, and startup shares cannot be sold individually; exits take five to eight years or more. There is no secondary market. In practice property loans have run longer than planned, and money in projects in proceedings may stay locked for years.
Our view
Return: Medium — the loans carry 9.52% a year on average in their contracts, but no measured return after losses is published. Risk: Very High (higher means more risk) — 7.93% of the money lent has been lost for good, more than a fifth is lost or in serious trouble, the operator itself went insolvent and was sold by the court in late 2025, and investors now pay recovery costs. Risk-return: Very Low — a middling contract rate does not make up for this level of losses and the platform's own failure.
WiSEED SA (company number 504 355 520) holds a European crowdfunding service provider licence from the French market regulator (AMF), number FP-2023-33, granted on 15 November 2023, for placing bonds and shares, with passports to Belgium, Germany, Spain, Italy, Luxembourg and the Netherlands. The company entered court-supervised rescue on 20 October 2025 and its business was sold by court order to Advenis Wise on 11 December 2025. In August 2026 the licence was still in WiSEED's name and no Advenis company held its own. No compensation scheme covers the investments.
