Caption selects Mangopay to power investor payments

By Vriti Gothi

Paris-based investment infrastructure provider Caption has selected Mangopay to manage payment flows across its investor base and network of professional distributors, as the platform seeks to scale operations and support more complex private market transactions.

Under the agreement, Mangopay will provide a wallet-first payment infrastructure including pay-ins, instant payouts, and know-your-customer (KYC) services. The setup is designed to manage multi-party investment flows while aligning with Caption’s regulatory obligations under its Investment Services Provider (PSI) status.

The move comes as Caption expands both transaction volumes and product structures. The company said it required a payment system capable of decoupling pay-in and payout flows, allowing it to determine when funds are collected and distributed and to progressively evolve toward end-to-end transaction processing. This flexibility is considered critical in private markets, where settlement timing, escrow arrangements, and fee allocation can vary significantly across deal types.

Mangopay also worked with Caption to design money flows and fee structures for a new investment product. The framework enabled Caption to test the product’s commercial viability under live market conditions before validating it for long-term deployment.

Caption operates a curated investment marketplace offering equity and bond instruments, with a focus on profitable SMEs, expanding franchises, and select alternative assets. In addition to its direct-to-investor platform, the firm has developed a B2B arm, Caption Services, which provides regulated infrastructure to asset managers, wealth advisers, and other intermediaries distributing investment products.

To date, Caption has facilitated more than €110 million in fundraising through club deals and private equity and debt transactions, supporting between 25 and 30 companies annually. As its ecosystem has broadened, the need for a unified, compliant payment framework has become more pronounced.

The partnership highlights a wider shift in capital markets infrastructure, as investment platforms increasingly serve diverse participant groups from retail investors to asset managers and distributors within a single digital environment. As private market distribution becomes more fragmented and technology-driven, payment providers capable of handling complex fund movements and regulatory requirements are emerging as critical enablers of scale.
