Buildkite is a CI/CD platform company whose hybrid architecture runs pipelines on customer infrastructure via a cloud control plane, with products spanning build automation, test analytics and package management.
Buildkite, founded in Australia in 2013, builds CI/CD infrastructure for engineering teams that prefer to keep control of their own compute. Its platform runs a hybrid model: a cloud control plane orchestrates pipelines while agents execute on customer infrastructure, allowing workflows to be composed to fit the team rather than the reverse. The design has attracted customers including OpenAI, Anthropic, Uber, Airbnb, Canva, Shopify and Pinterest.
The engineering agenda is defined by scale problems. Massive parallelization cuts build times by as much as 90% on the fastest pipelines; across its customer base, the company counted over 18,000 years of developer time saved in 2023. The product portfolio has expanded deliberately: Test Analytics launched in 2021, and the 2023 acquisition of Packagecloud added native package and artifact management - the company's first acquisition.
Buildkite was bootstrapped in Australia and has retained the architectural independence that choice implies, taking a path distinct from its larger competitors. It has raised $59m in total, comprising a $28m Series A in 2020 and a $31m Series B in 2022. The company operates globally, and its stated mission is to unblock developer innovation.
