Tallinn Estonia GitHub Actions runner platform using gaming CPUs for 2x faster CI at lower cost; YC W23 $500K with $330K ARR competing with Depot and Blacksmith for CI/CD performance optimization infrastructure.
BuildJet is a Tallinn, Estonia-based continuous integration (CI) performance platform — backed by Y Combinator (W23) with $500,000 raised from YC in 2023 — providing developer teams with GitHub Actions runners powered by gaming CPUs (AMD Ryzen and Intel Core processors optimized for high single-core clock speeds) that execute CI/CD builds 2x faster and at lower cost than GitHub's standard hosted runners, enabling companies to reduce their CI infrastructure spend and development cycle time simultaneously. Founded in 2022 by Adam Shiervani and Lian Duan and generating $330,000 in annual recurring revenue as of September 2025 with a 3-person team, BuildJet serves the developer community's need for faster and more affordable GitHub Actions compute.
OpsLevel is a developer portal and service catalog for tracking service ownership, maturity scorecards, and production readiness across microservices.
OpsLevel is a developer portal platform that gives engineering organizations visibility into the services they operate, who owns them, and how mature they are relative to internal engineering standards. At its core, OpsLevel maintains a service catalog that maps every microservice, repository, and infrastructure component to a team owner, populating metadata automatically from integrations with GitHub, GitLab, PagerDuty, Datadog, and cloud providers. This catalog becomes the authoritative source of truth for answering questions like who to contact about a service, what tier of reliability it requires, and what dependencies it has — questions that are often unanswerable at engineering organizations that have grown past the point where everyone knows everything.
