VC investors evaluate startups based on four main criteria: market opportunity, team strength, product traction, and risk mitigation. They look for startups addressing huge markets with the potential for $100M or more in annual revenue. They evaluate the strength, experience, and track record of the founding team. Investors want to see real product traction using metrics like acquisitions, activations, revenue, and retention. They seek to mitigate risk by investing in startups with strong execution and a clear path to addressing large markets. The evaluation process typically takes around six months.
