Angel Investor: Role, Criteria and Importance in Early-Stage Startup Funding
Why Do Startups Need Them?
An angel investor – also known as a business angel or seed investor – is a high-net-worth individual who invests their own capital in early-stage startups. But it’s not just about money. Many angels also provide hands-on support, sector knowledge and access to valuable networks.
They fill the funding gap between friends-and-family rounds and institutional investors such as venture capital (VC) funds.
