Industry Mainstay

Keeper.app is a verified, high-growth B2B SaaS company backed by Y Combinator (W21). External data confirms a team size of ~57 employees and estimated annual revenue in the $5M–$10M range, positioning it significantly above the calibration baseline. The software solves a critical workflow problem for bookkeepers with features like automated error detection and client communication. However, the submission itself contained low-effort, hyperbolic claims (e.g., 'most people have used my product', 'audience: everyone') which negatively impacted the Quality Factors for Reach and Traction. Despite the poor submission quality, the underlying business fundamentals are strong.
