What is an angel network?

An angel investor is typically a high-net-worth individual (HNWI) who backs ambitious, high-growth businesses, often using capital earned through previous exits or entrepreneurial success. Compared to venture capital firms, which invest institutional money, angels provide a more personal and hands-on approach to funding.

Angel networks bring these investors together. They collaborate to discover, assess and back promising startups, usually by pooling their capital into shared funds or syndicating deals. Many also offer follow-on support, industry expertise, and access to valuable business networks, making them a powerful partner for any startup founder.
