Henry Hyder-Smith and Steve Denner started UK-based Adestra in 2004. Adestra is a digital marketing software that helps big companies handle email campaigns, among other things.

The company grew nicely. By 2016, it had around $9 million in revenue and a client list that featured some of the U.K.'s best companies. Hyder-Smith and Denner decided it was time to go beyond their borders and enter the U.S. and Asian markets. To fund the effort, they raised $7.2 million from the Business Growth Fund (BGF), one of the U.K.'s largest private equity groups. BGF's investment valued Adestra at around $35 million — a little shy of four times revenue.
