A little startup called Firespotter Labs has some major backers and big ambitions in the voice space. The company was at ITEXPO (News - Alert) Miami earlier this year telling its story. And its CEO, Craig Walker (founder of Google Voice and Dialpad), was among the judges at the colocated event, StartupCamp 7.

Firespotter (News - Alert) Labs, now a two-year-old enterprise, this summer closed a $15-million Series B round, which was led by Andreessen Horowitz, with participation from existing investor Google (News - Alert) Ventures. That is helping fuel Firespotter Labs’ ambitions to expand its profile in audioconferencing and beyond.

Conferencing is a multibillion dollar industry, noted T.R. Missner, head of telephony at Firespotter Labs. But it’s not the end-all for the company, he added. Firespotter Labs expects to do more for SMB and enterprises in the voice space.

Missner declined to elaborate on what that means. But he did provide details on the company’s existing audioconferencing service.

Known as UberConference, the service launched last May. The UberConference line includes free, paid and enterprise-grade versions. The $10/month paid option enables users to select a local number and can support up to 100 users on a call (the free version tops out at 20). The enterprise version, meanwhile, allows an administrator to manage multiple UberConference users through a single account.

And the company in December came out with an Android (News - Alert) app that has seen 10,000 downloads.

What’s unique about UberConference, according to Missner, is that it was built with quality and ease of use as the central goals. He said the team at Firespotter Labs, which includes former Google and Microsoft (News - Alert) employees, is “good at design and blending voice with awesome Web design.”

Firespotter Labs, which now has about 27 employees and recently moved its offices to downtown San Francisco, is also looking to rapidly expand its ranks.

“We are hiring like crazy,” said Missner.
