SumatoSoft vs Infinum: 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.

Infinum

Infinum was registered in Zagreb in May 2005 and reported more than 370 people in 2025. Its best-known IoT project is HomeID for Versuni, the Philips appliance maker, which replaced several separate appliance apps with one device companion app and community hub. A Clutch review also describes IoT development and DevOps for a machinery manufacturer on Azure. Infinum is an app and product agency first, with strong design, and does not build hardware.
