Willem co-founded Gorilla in 2018 to address one of energy retail’s most persistent challenges: how to price, forecast and protect margin in markets where inputs move faster than the existing technology systems can keep pace with.

Today, Willem leads Gorilla’s customer organisation across the UK, Europe, Australia and North America, working with energy retailers ranging from challenger brands to major incumbents. His focus is helping retailers build the data, operational and commercial capabilities required to improve decision-making and protect realised margin.
