About us

ObjectBox (Techstars ’17) is a company that helps app developers develop faster apps faster by ensuring data is where it is needed when it is needed. The core of this solution is our superfast lightweight, embedded database with super easy native language APIs for Java, Kotlin, Swift, Dart (Flutter), Go, and C / C++. On top of the database, we’re building a data synchronization solution (currently in Early Access and so far demonstrated great efficiency – above alternatives).

We are also the team behind the open source projects greenDAO and EventBus.
