About StarSling: DevOps should be as agentic as coding.
We're building AI agents for the work developers shouldn't have to do. CI is where we're starting: the bottleneck every fast-moving team eventually hits.
Our story
Daniel led a 12-person engineering team at Netflix that built their Internal Developer Portal (IDP) called Netflix Console. Netflix Console was the "command center" for Netflix's 3,000+ engineers, managers and leaders and became the highest DAU internal tool for developers at Netflix. Prior to that he was a Software Engineer at Facebook where he worked on the AI Camera team on a computer vision library that currently powers camera effects for 100M+ DAUs across IG, FB, and WhatsApp.
Yonas was previously Founder & CEO of StackShare, a community of over 1.5M developers and engineers. StackShare let developers compare and discuss tech stacks and it became the top destination for anyone choosing between developer tools. StackShare's enterprise SaaS offering was used by Fortune 500s to scan across thousands of internal codebases to surface tech stack data via dashboards and APIs. StackShare was acquired by FOSSA in 2024.
We've been friends for over 10 years and decided to start StarSling in 2025 after realizing how far behind production DevOps tooling was compared to local coding agents. Developers typically lose ~20% of their day on annoying tasks outside of coding: investigating CI pipelines, fixing exceptions, improving app and database performance, resolving incidents, and more. So we thought, what if agents could take these tasks off your plate so you could spend all your time building features and products.
We joined YC's first Spring batch in April 2025 with a vision to build AI agents for all the DevOps tasks developers have to take on. StarSling is headquartered in San Francisco, California.
While building those agents, we ran into the same wall as everyone else: coding agents now write a change in five minutes, but CI still takes ten or more. CI had quietly become the bottleneck on how fast we could ship.
So we built the CI we wanted: fast on the first run, and faster over time as agents read your workflow logs, timing, and telemetry, then open optimization PRs you review and merge. We introduced StarSling Runners on April 30, 2026, and they became generally available on June 29, 2026 after running over one million CI jobs for teams including Better Auth, Mastra, and Partcl.
