Santa Monica telecom startup CallFire has named a new chief executive.

The company said Friday it has promoted Ron Burr, formerly the company’s chief revenue officer. He replaces CallFire co-founder Dinesh Ravishanker, who has left the company.

A spokeswoman told the Business Journal that Ravishanker has stepped down to focus on new ventures, including two other startups he recently co-founded.

“This was the natural transition of an entrepreneurial co-founder who brought on a seasoned executive to run strategy, and they had always intended for Ron to ultimately take on the chief executive position,” the spokeswoman added.

Burr is co-founder and former chief executive of Woodland Hills Internet provider NetZero. He joined CallFire last year.

Ravishanker co-founded CallFire in 2005 with Komnieve Singh, Vijesh Mehta, TJ Thinakaran and Punit Shah. The company runs Internet-based call centers that can run automated phone campaigns. For example, CallFire worked with the Democratic Party to run phone polls during the 2012 election.

The company has about 200,000 customers, including Public Storage and Pepsi, and has run 200 million campaigns.

Burr was brought in to grow the company further.

“As an Internet industry pioneer who founded and led multiple leading internet companies to highly successful market positions, Ron was the right person to help introduce CallFire to the business community and grow our footprint in multiple markets,” Singh, CallFire’s president, said in a statement. “We are thrilled that Ron is now stepping up to the chief executive position – helping to further scale the business as we move to the next phase of growth.”
