Five metrics reveal whether an AI business is viable, a post argues

A post proposes five tests for an AI business: gross retention, net revenue retention, usage, pilot win rates and gross margin. For Legora, the author reports 95% gross retention and 300%-plus net revenue retention. The reported ratio of daily to monthly active users exceeds 50%, with the average active user spending 17 hours a month in the product. The author also reports a 78% pilot closed-won win rate for August 2026 and says Legora’s gross margin is positive and improving every quarter. The central argument: adding customers who cost more to serve than they pay is not a sustainable path to growth.
