Diadem Capital is a fundraising marketplace and warm introduction network designed to connect startups with investors and lenders, aiming to make funding rounds faster and more efficient. The platform utilizes AI to match high-growth companies with capital providers. They charge a 1% fee on the round or a 3% fee on capital introduced for equity funding, and a 1% success fee on debt and non-dilutive raises. Their target clients are venture-backed companies or founders with prior VC experience in specific geographies (USA, Canada, Western Europe, Israel, Australia) seeking $2M-$100M in equity or $100K-$100M in debt. The platform boasts over 1,000 investors and 250+ lenders, with a stated goal of closing rounds 5x faster. They emphasize a founder-aligned process that combines technology with personal relationships, differentiating themselves from traditional brokers and placement agents who charge high upfront fees.
