The funding will be used to accelerate Silo AI’s expansion in the Nordics and in Europe, supporting the company’s vision of building safe, human-centric AI.

Silo AI was founded in 2017 to connect leading AI scientists with real-world problems and help companies succeed in building cutting-edge AI.

Silo AI has sustained exceptional growth over the last few years, with an impressive and continuously expanding client list of global industry leaders, such as Allianz, Danske Bank, Körber, Philips, Rolls-Royce, Sandvik and the United Nations. Silo AI had a revenue in 2021 just north of EUR 12m.

On our long-term commitment to build a European AI flagship, we’re still in the very beginning. I am more than honored to continue this exciting journey with all Silonauts, and to welcome Altor onboard.”
