Ian Blaine, thePlatform's chief executive, said today that Comcast purchased his company for an undisclosed amount.
The 70-person Seattle company helps media companies and broadband and wireless service providers deliver video to consumers. Comcast Interactive Media, which bought the company Tuesday, was using thePlatform's service to deliver video over the service called The Fan.
The news was first mentioned on PaidContent.
Blaine said that thePlatform, which had raised more than $12.5 million in venture capital, wasn't looking to be sold.
"We really weren't," he said. "We were very focused on building our business and things were going well. We have been a provider to Comcast for years and knew them well, and they knew us well. This came out of that relationship."
thePlatform will be a wholly owned subsidiary of Comcast in Seattle. Blaine said thePlatform will continue to grow agressively and could have as many as 100 employees in the next six months.
