Peak was acquired by Zynga for $1.8bn in 2020, becoming Türkiye’s first unicorn exit.

Earlier in her career, she worked at Morgan Stanley and private equity firm Turkven. She holds a BA in Economics from Harvard University.

Spyke Games is an Istanbul-based mobile games developer founded by Rina Onur Şirinoğlu, Remi Onur, Barkın Başaran, Fuat Coşkun and Mithat Madra. The founding team brought together senior experience from Peak Games, Zynga and Riot Games.

The studio initially experimented with social casino game Royal Riches before shifting its focus towards puzzle games. Its breakthrough title, Tile Busters, launched in 2022 and became Spyke’s most successful game, establishing the studio in the competitive tile-matching category. The company subsequently expanded its portfolio with titles including Blitz Busters and Yarn Loop. Released in late 2025, Yarn Loop has emerged as another significant title for the studio, building momentum in the fast-growing sorting puzzle category.

Spyke raised $55m in a seed round led by Griffin Gaming Partners in January 2022. In 2024, Moon Active invested approximately $50m for a minority stake in the company, taking Spyke’s total funding around $105m. The investment has supported the studio as it expands its portfolio while maintaining its focus on free-to-play casual mobile games.
