About
PropelAuth is a Mountain View-based authentication infrastructure company specializing in B2B SaaS authentication — providing pre-built team and organization management features (multi-tenant organizations, team invitations, role-based access control, SSO/SAML, and user management) that B2B SaaS companies need but are time-consuming to build from scratch. Founded in 2021 and backed by Y Combinator (W22) with $3.09 million raised from Tiger Global, 8-Bit Capital, and others, PropelAuth generated $1.1 million in revenue in 2024 with a 7-person team.

About
Stably AI is a San Francisco-based AI test automation platform — backed by Y Combinator — reaching $1 million in annual revenue in December 2024 with a 5-person team — providing engineering teams with an AI platform that auto-generates, runs, and maintains end-to-end tests in CI/CD pipelines with zero-flakiness guarantees and self-healing capabilities that automatically repair tests when UIs change, replacing the brittle Playwright and Cypress test suites that break with every UI update. Founded in 2023 by ex-Google Chrome infrastructure engineer Jinjing Liang (CEO) and ex-Uber Safety ML engineer Neil Parker (CTO), Stably enables customers like OpenArt (which scaled to $16M ARR with a 10-person engineering team using Stably) to achieve test coverage without dedicated QA engineers.
