Sarasota, Florida-based Voalte, which equips healthcare provider teams with its iOS-based clinical communication offering, has raised $6 million in a strategic round of funding led by an undisclosed healthcare information technology leader and an unnamed major healthcare system.

The company plans to use the funds to add 100 new employees to its team, which would see its ranks tripling from 50 employees today to 150 in about 18 months time. Last year Voalte received a $250,000 grant from Sarasota's Economic Development Corp. to help create 50 new jobs at the company over the next three years.

Voalte's technology enables care teams to exchange voice calls, text messages and field incoming alerts right from their iOS devices.

Voalte's healthcare provider customers include Massachusetts General Hospital, Texas Children's Hospital, and Nebraska Medical Center among others, while its developmental partners include Cedars-Sinai, Sarasota Memorial Health Care System, and Huntington Medical Center. The company claims to have about 20,000 clinician users and about 5,000 iPhone deployed across the country. Voalte first launched its services in 2009 after its founding in late 2008.

While Voalte declined to disclose the name of the HIT company that co-led its strategic round of funding, the company already has partnerships in place with Philips' Emergin, Rauland-Borg, Epocrates, and AirWatch.
