Investment thesis

Alpha Partners operates a co-investment model focused on later-stage venture rounds. It partners with early-stage VCs by sharing economics, gaining access to pro-rata and follow-on opportunities in their most promising portfolio companies. The firm targets Series B and later US tech growth rounds, positioning itself as a 'venture super-connector' with a network of over 1,000 VC partners and events serving 1,500+ VC professionals annually. Its approach centers on backing established investors ('the legends') rather than sourcing deals directly, participating in later-stage rounds led by other funds.
