About us

We build an open image annotation platform to facilitate and accelerate the development of AI models

At LabelFlow, we build an open image annotation platform. Our mission is to facilitate and accelerate the development of AI models at scale thanks to top-notch labelling tools and a public library of image datasets.

LabelFlow is being built with the experience accumulated by Sterblue (Y Combinator S18), where we have learned first-hand the importance of quality datasets to automate wind turbine and powerline visual inspections.

We are a small team based in Nantes and Lisbon and we are going full remote. For timezone convenience, the positions are opened in Europe only at this time. We are product driven engineers and developers committed to move fast and execute the best work of our lives!

We are proud of being among the first top 10% of startups rated by Earlymetrics (rating agency for startups and SMEs).
