Here at Uncapped, we believe founders shouldn’t have to give away ownership of their company to fund growth. That’s why we provide no-security and no-equity investments from £10k - £2 million to founders and companies who are changing the world. We charge a flat fee of 6-12% on the capital provided and get repaid through a revenue share. There are no pitches, cap tables or coffees required. So founders can apply online, receive an offer and focus on growing their business! We’re a fully remote company and backed by Europe’s top investors including Seedcamp, Global Founders Capital, Whitestar, and Mouro Capital (Santander Bank) - early investors in other fintechs such as Transferwise, Revolut, and Funding Circle.
