Lemberg Solutions vs SumatoSoft: overview
Lemberg Solutions
An IoT app is only as reliable as the firmware and cloud it talks to, and Lemberg Solutions is one of the few vendors on this list that builds all three in-house. Founded in 2007, the company has 200+ employees and offices in Lviv, Hamburg, London and Kraków. Its IoT work covers consulting, cloud architecture with device management and OTA updates, iOS, Android and web apps, embedded software, PCB design and prototyping, all backed by an in-house lab. Named clients include Astronics, Caltech, Speede, Ferno, Cellink and Bosch Rexroth, and the published case studies include telemetry for Voltfang's energy storage systems and control software for a 360 kW EV charging station.
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.
