UK-based engineering firm Revolve Technologies was formed by an MBO in 2007 when Roush Industries (an engineering arm of the Roush empire that is perhaps best known for Roush Racing and NASCAR) decided to divest its European operations. Revolve says it has a diverse portfolio of multi-tier automotive and non-automotive clients across a broad spectrum of industries including car and commercial vehicles, transportation, infrastructure, agriculture, defence and energy. Dave Leggett recently spoke to John Mitchell, Managing Director, and Chairman Andrew Williams, to find out more about the business.
