Zühlke vs SumatoSoft: overview
Zühlke
Zühlke has engineered products from Schlieren, near Zurich, since 1968 and now employs roughly 1,500 to 2,000 people across Europe and Asia. Its connected-product work leans toward regulated and industrial clients: medical devices, laboratory equipment and machinery, where the app must pass audits as well as user tests. The firm handles product strategy, hardware, firmware, cloud and apps. Swiss and German pricing puts it at the top of the cost range on this list.
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.
