How We Evaluate Investment Potential

Our watchlist scoring framework evaluates cybersecurity startups across five dimensions: growth velocity, product differentiation, enterprise traction, investor signal strength, and founder-market fit. Each dimension is weighted and calibrated against our database of 40+ companies tracked quarterly since 2023.

Companies are assigned one of four status categories based on their score trajectory: Must Watch (sustained top performance), Rising (improving trajectory), Steady(consistent but not accelerating), and Cooling (declining signals). Status changes are reviewed and published quarterly.
