19: Rank Group (2016)

Rank Group has moved into the top 20 following a 12-month period in which CEO Henry Birch’s digital transformation really began to take shape.

Earlier this year the firm undertook a major migration from its OpenBet platform to one provided by Bede Gaming and, despite this upheaval, still managed to post an 11% increase in full-year revenues.

The year also saw Rank push forward with its omni-channel strategy as it looks to better utilise its retail strength and revealed plans to launch a new bingo brand, thought to be called Luda, next year.

While the operator added a Kambi-powered sportsbook to its Grosvenor brand in May, Rank joined forces with 888 to try and form a three-way merger with William Hill. Although unsuccessful, the move illustrates the scale of Rank’s ambition.
