Beseif is a Spanish fintech that provides a secure payment escrow, shipping, and product-verification layer for peer-to-peer transactions on secondhand classifieds sites like Wallapop and Milanuncios. Founded in 2016 and based in San Sebastián (Basque Country), it protects buyer funds until delivery is confirmed and manages courier pickup, 48-72h shipping, and returns. It closed a €300K seed round led by Easo Ventures via an equity-crowdfunding campaign on Startupxplore that hit its funding cap within 24 hours.
