DAC.digital vs Intellectsoft: overview

DAC.digital

DAC.digital has been based in Gdańsk since 2009, and directories put its team somewhere between 50 and 250 people. Its profiles describe work across embedded systems, IoT, computer vision and the back-end platforms that collect device data. For IoT app buyers the appeal is the mix of edge processing and cloud work in one EU-based team. Consumer mobile design is less visible in its public portfolio than industrial and data work.

Intellectsoft

Intellectsoft was founded in 2007 and most directories list New York as its headquarters, with offices in the UK, Norway, Ukraine and Latin America. Its team is estimated at 150 to 300 people. IoT is one of five labs the company advertises, and client reviews mention IoT integration within full-stack projects.
