AtomicJar, the Newark-based company behind the popular open-source library Testcontainers, on Monday announced it secured $25 million in Series A funding.
Founded in 2021, AtomicJar offers an integrated testing platform that enables developers to build databases and web frameworks. To date, the open-source offering has helped engineering teams at companies like DoorDash, Spotify, Uber and Google test software, surpassing 100 million downloads last year. The platform aims to make developers more productive, the software they write more resilient and the organizations they work for more agile through Testcontainers and the Testcontainers Cloud.
Insight Partners led the Series A round with boldstart ventures, Tribe Capital, Chalfen Ventures, Irregular Expressions and several individuals also participating. Including the new funding, AtomicJar has raised $29.1 million to date, according to data from Crunchbase.
Testcontainers Cloud offers installations in five minutes and provides consistency in test results, faster execution and elastic resources that it says are always available. The company said the service removes all hardware and software limitations, providing a productivity boost for engineering teams. Benefits include being able to test everything on laptops without worrying about resources, running test suites without scaling up a workforce and enhancing team efficiency by ensuring consistency from development to continuous integration.
