With texting apps from Line to Viber to Facebook's WhatsApp vying for teens' attention, is there a messaging start-up bubble set to pop? Chris Best, co-founder and chief technology officer of Kik, thinks there may only be room for one major mobile chat platform.
"I do think in the race to become the dominant chat platform, there may be a winner-take-all. And we've seen that in WeChat in China," Best said on CNBC's "Squawk Box" Wednesday.
Best is betting that Kik will be that winner in the U.S.
