Speaking last night at the opening party of StartX OpenX, WhatsApp co-founder Brian Acton addressed concerns about the Facebook acquisition. Many users were worried that Facebook acquired the messaging service for its data on 450 million-plus users. But according to Acton, WhatsApp sees the deal as an investment.

“WhatsApp doesn’t have much data. We don’t have much beyond a phone number to work with. Yeah, on Facebook, you have your name, your age… your email address… We don’t have a lot of data to share to start with,” he said.

Acton said that once the company started to grow, it could either go public or get acquired. He was glad for Facebook’s offer, as he didn’t want to go through the IPO process.
