Annotell is a provider of a platform that makes creating high quality training data for supervised machine learning a radically smoother process.

Annotell allows mobility companies to ensure high-quality performance of self-driving cars’ perception systems.

Annotell was founded in 2018 by Daniel Langkilde and Oscar Petersson. The company is headquartered in Gothenburg, Vastra Gotaland County, Sweden.


Annotell combines highly automated annotation with detailed quality analytics and data browsing, and reduces the development cost and shortens the production timeline without compromising on safety.


Annotell’s approach to complementing what machine learning can teach systems is as progressive as autonomous systems are today: in part it tests and formalizes the limitations of systems that by their nature are not designed to be fully autonomous.


Annotell works with several AD companies such as Zenseact (fmr. Zenuity), a subsidiary of Volvo Cars, and Volvo Group and have a global client base and offices in Gothenburg, Sweden as well as Munich, Germany.


Annotell is backed by Metaplanet, NordicNinja, Ernström & Co, Sessan AB, and others. The company raised $24M in Series A round on Feb 03, 2022. This brings Annotell's total funding to $30.8M to date.
