Claim, a platform that is both a rewards app and a social network, has raised $4 million in a seed funding round led by Sequoia Capital. The startup is on a mission to make shopping fun, rewarding and social. The app launched on an invite-only beta in January and is currently focused on university and college students in Boston. With Claim, users and their friends can earn cash back, exchange rewards and even redeem them together. The platform is a social network that aims to focus on real-world value and communal experiences rather than manufactured content and reposts. The startup was founded by CEO Sam Obletz and CTO Tap Stephenson in November 2021. The duo met when they became roommates at Yale and came up with the idea for Claim when they reunited in business school at Harvard.
