The Annotation Platform for Consistent Training Data


When developing safety-critical systems, the performance and reliability of your software are of utmost importance. As machine learning systems are programmed through their training data, the training data determines the behaviour of your product. Despite this, a major bottleneck for most machine learning teams is access to consistent data.

The hardest part of creating consistent training data is getting people to agree at scale. Solving this challenge is at the core of Annotell and why we were founded in the first place.

We enable the automotive industry to develop safe autonomous vehicles by providing our clients with accurate, precise and consistent training data. We can do this by ensuring agreement at scale.
