Apriorit vs Intellectsoft: overview

Apriorit

Apriorit has been building low-level and security software since 2002, with a US legal entity in Delaware and engineering teams in Ukraine and elsewhere in Europe. Its specialties are drivers, kernel work, reverse engineering and cybersecurity, and it applies those to IoT device security and embedded projects. Public figures put the team at 300 to 500 (per company website; independently unverifiable precise figure). Buyers with security-sensitive devices get more from it than buyers who mainly need a consumer app.

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. It is a general digital agency first, so IoT depth is lighter than at the specialists above it.
