MobiDev vs Jelvix: overview

MobiDev

Mobile apps with an applied AI or computer vision component are MobiDev's specialty, delivered from R&D centers in Poland and Ukraine under a company incorporated in both the US and UK since 2009. The company has built a visible specialization in mobile app development and computer vision work for startups and mid-size product companies. That dual-country R&D structure spreads delivery risk but means, like several peers, Ukraine is a delivery location rather than the company's registered domicile.

Jelvix

Jelvix lists headquarters across four cities at once, Tallinn, Kharkiv, Stuttgart, and London, an unusually distributed structure for a company founded in 2011. It positions itself as a general custom software and staff-augmentation vendor for mid-size businesses, with case studies leaning toward standard web and enterprise application work rather than a named technical specialization. That distributed footprint can make it harder for a buyer to pin down which legal entity they would actually be contracting with, worth confirming directly before signing.
