Evnex makes charging solutions for electric vehicles. Ed talks about spending a year developing their first electric charger, then working out how to turn a technology into a company: better understanding the market, learning how to raise money and how to hire people. Now there are a lot of competitors & a slowdown in the market so he needs to think deeply about how to win. Ed's advice for success: play to win – narrow your focus to something at which you can be the best.
