Mobile gaming firm Scopely raised $55 million in its latest funding round, which it said will “fuel further investment in its product slate and developer ecosystem”.

It said in a statement it will continue to invest in its top grossing games, The Walking Dead: Road to Survival and Yahtzee with Buddies, which both launched last year. The Walking Dead has been installed by more than 20 million players to date, added the company.

Scopely describes itself as a mobile entertainment network which “brings the traditional entertainment model of blending in-house development with hand-picked second-party talent and intellectual properties to build out a catalog of carefully cultivated franchises to mobile free-to-play games”.

“We have a differentiated, scalable model in the games industry that can create durable long term revenue streams across multiple genres,” said Walter Driver, CEO and co-founder of the company.

“Scopely’s growth has been driven by our focus on publishing and monetising products which we can do systematically and sustainably.”

Led by Greycroft Growth Fund, the series B funding round means the company has now raised $98.5 million in total.

Scopely said it has been growing revenue by “more than 500 per cent over the past 18 months”, and described itself as a “rising force in the $25 billion mobile games market”.

Other investors involved in the funding are Elephant Partners, Evolution Media Capital, Highland Capital, Sands Capital Ventures and Take Two Interactive.
