TypeSafe AI

TypeSafe AI, originally founded as Typesafe in 2011 by Martin Odersky (creator of Scala), Jonas Bonér (creator of Akka), and Paul Phillips, is a software company that provides a platform for building reactive applications on the Java Virtual Machine (JVM). The company's core offerings include the Scala programming language, the Akka middleware, and the Play Framework, along with supporting tools such as the Slick database library and the sbt build tool. Typesafe also offers training, consulting, and commercial support for these technologies. In February 2016, the company rebranded from Typesafe to Lightbend and adopted a new logo. Under the Lightbend name, it continues to lead open-source projects like Akka and has been a core participant in Scala development. The company offers commercial products such as the Lightbend Subscription (24/7 developer support) and the Lightbend Production Suite (service orchestration, monitoring, application resilience, and enhanced availability). Lightbend is also a main contributor to the Reactive Streams initiative and has initiated conferences like Scala Days and Reactive Summit. Lightbend is privately held and has raised funding from investors including Greylock Partners, Shasta Ventures, Juniper Networks, Intel Capital, Blue Cloud Ventures, Bain Capital Ventures, and Polytech Ecosystem Ventures. The company is led by CEO Tyler Jewell and CTO Jonas Bonér. Its technologies are used globally by developers building scalable, resilient systems.
