Promwad vs Integra Sources: overview

Promwad

Founded in 2004 and headquartered in Essen, Germany, Promwad runs additional engineering centers in Latvia and Serbia — both established nearshore-Europe delivery hubs offering lower engineering cost than Western Europe while remaining EU-adjacent (Latvia is an EU member; Serbia is an EU-accession candidate with strong engineering talent at competitive rates). This multi-country nearshore structure lets Promwad offer German-market client-facing presence with Baltic and Balkan delivery cost.

Integra Sources

Integra Sources, founded in 2014, is a compact turnkey hardware-and-firmware shop with public sources disagreeing on both its exact headquarters (most list Astana, Kazakhstan) and current headcount (roughly 24 to 51 employees). Kazakhstan is an unusual but genuine offshore-cost outsourcing base — outside the more commonly discussed Eastern Europe/South Asia corridors — and the firm reports 250+ completed IoT and embedded projects, a useful volume signal for a small team at this cost tier.
