Last month, Skydeck released the beta version of its mobile phone app. By the end of the year, the 1-year-old company plans to formally launch the application and itself, according to CEO Jason Devitt.

Skydeck's software allows users to keep track of and search through their cell phone calls much as they would their e-mail.

Devitt declined Tuesday to say how many people have signed up to use the software. But at a dinner of venture capitalists and startup execs, he said the take up has been good and is meeting his expectations.

The early adopters are professionals, such as sales people, lawyers and real estate agents, he said. The company expects to make money by offering business applications, including one to work with Salesforce.com software.
