FanDuel has set its focus on mobile expansion after acquiring app developer Kotikan.

The deal, worth an undisclosed sum, was announced just days after the daily fantasy US market leader revealed that it had raised $275m (€250m) in its latest round of funding.

Both companies are based in Scotland, with Kotikan, which has a turnover of £2.4m and employs 56 staff, having worked on FanDuel’s iOS and Android platforms since 2013.

“At FanDuel we set the bar consistently high and hire only the best talent - this acqui-hire of Kotikan strengthens our existing team and will help drive forward the business,” said FanDuel chief executive Nigel Eccles.

The purchase, along with other recruitment in Scotland and the US, will see FanDuel’s workforce rise from 100 to more than 500 in less than a year.

Kotikan was founded in 2007 and has also developed apps for clients including Skyscanner and Standard Life.

Chief executive Gavin Dutch added: “Since we started working with FanDuel in 2013, it became more and more apparent that the two companies were incredibly well aligned in both values and culture, so this move feels very natural.

“The whole team at Kotikan are hugely excited to join FanDuel and pursue our shared ambition of creating a stratospheric success story for Scottish technology. We all care about the same things and are excited to make products that are loved by millions.”
