Upstream Labs
Built by people who lived the pain.
Upstream was founded by engineers who spent careers at Stripe, LaunchDarkly, and Statsig watching smart teams cause outages with badly-timed feature rollouts. We knew the tooling was broken. We built the fix.
Our mission
Make safe, fast software delivery a default — not a privilege of teams with dedicated SRE staff.
Upstream Labs, San Francisco CA — founded 2021
Founding team
8 people. One shared scar.
Every founder has shipped a flag that triggered a 3am page. That's not a coincidence — it's the product spec.
Spent 4 years building Stripe's internal deploy safety tooling. Left to build the version every team deserves, not just Stripe-scale teams.
Architected LaunchDarkly's edge evaluation layer. Knows where the performance cliffs are, and how to avoid them.
Led Statsig's Experimentation Platform product. Obsessed with the question: "what does healthy look like, and how do we encode it?"
Values
How we build.
Correctness over cleverness
A rollback that works beats a prediction that's almost right. We optimize for the boring outcome: nothing breaks.
Transparent by default
Every rollout decision is logged with a reason. You should always know why Upstream did what it did.
Quiet when things are fine
We earn trust by not pinging you unnecessarily. Noise is a bug. A healthy rollout produces one notification: done.
