Investment thesis

Gateway Ventures operates a digital business angel platform that lets private investors participate in curated startup deals from a minimum ticket of €10,000, far below typical VC fund minimums. An in-house venture team and co-investor network source and screen opportunities, and only a small fraction of startups pass a multi-stage due diligence process. The firm prepares pitch decks, data rooms and term sheets on its platform, introduces founders at online meet-ups, handles legal closing documents, and provides ongoing reporting and update calls after investment. Investors pay no membership or due-diligence fees upfront; the firm charges 5-7% transaction and portfolio-management fees only when an investment is made.
