Hjalmar Nilsonne is the CEO of green gadget company Watty, which raised more than 3 million dollars in 2016 and was recently listed as among the 100 hottest startups in Europe by Wired magazine. The company makes a gadget that helps users save money on domestic energy bills and cut down on carbon emissions.

In this episode Hjalmar shares his journey and his hopes for the future. You can support The Stockholmer’s fully independent journalism by making a one-off secure contribution of any amount.
