Periscope CEO on Android users flooding in

Periscope CEO: Our most important metric

Android users haven't been this excited in a while.

Periscope, the Twitter-owned live streaming app, just launched for Android devices on Tuesday after having only been available on iOS for two months. But Android users aren't acting bitter.

Periscope CEO and co-founder Kayvon Beykpour said Thursday that the uptake from Android users in under 48 hours has been fascinating.

"It's been unbelievable to see," he told CNBC's "Squawk Alley." "What's really exciting for us about Android is it gives us exposure to markets that we don't have as much penetration on with iOS." Asia in particular remains a big opportunity for Periscope, where Android devices have performed better relative to other markets. Beykpour noted Turkey as a good example, now one of Periscope's top five countries by users.

But as more users have Periscope made available to them, the more piracy concerns could grow as well. Just last month Periscope came under fire after users live streamed the pay-per-view fight between Manny Pacquiao and Floyd Mayweather. But Beykpour says he isn't concerned, as media companies start to see the appeal of partnering with Periscope.

"We tried to make it clear that piracy doesn't excite us in any way," he said. "What we are legitimately excited about is working with our partners like these media companies—like CBS, HBO, Showtime—to actually create compelling new original content."
