SumatoSoft vs Sigma Software: overview
SumatoSoft
SumatoSoft was founded in 2012 and has its headquarters at One Boston Place, with directory headcounts of 51 to 200. IoT is one of its named practices, alongside custom web and mobile development, and its published work centres on monitoring apps, asset tracking and the web dashboards that sit behind them. It does not design hardware, so it suits projects where the devices already exist or come from a hardware partner. It is a sensible mid-budget pick for app and cloud work on top of off-the-shelf sensors.
Sigma Software
Sigma Software dates to 2002 and is part of Sweden's Sigma group, with its legal base in Stockholm and most engineers in Ukraine and Poland. Headcount is in the 1,001 to 5,000 range. Its embedded and IoT unit sits beside automotive, telecom and gaming practices. The Scandinavian ownership appeals to Nordic buyers, while IoT app projects are a modest share of a broad portfolio.
