Heyzap, which built a social platform for mobile games, has raised $4.3 million in Series B funding.
The round was revealed in a regulatory filing (first spotted by The Next Web). Co-founder Jude Gomila confirmed the news over email and said the funding comes from existing investor Union Square Ventures and Qualcomm.
Heyzap was incubated by Y Combinator and started out as a platform for Flash games before refocusing on mobile. It has been rolling out a number of new features over the past few months, including player leaderboards and achievements, and the company says it now has 9 million registered users.
Gomila said the new funding will be used to hire engineers and salespeople: “Our leaderboards, achievements and ads SDKs are taking off and we want to fuel the growth there.”
Heyzap has now raised more than $8 million total.
