Doctor house call app Heal of Santa Monica raised a $26.9 million Series A round led by Legendary Pictures chief executive Thomas Tull’s company Tull Investment Group.

The company will use the funds to expand outside California and improve its software. The startup claims that by automating many of the administrative tasks typical in a brick-and-mortar health center, it can provide care much cheaper and more effectively, said Nick Desai, Heal chief executive.

“These doctors, when they are able to go into your house and see your environmental context, they are able to much more accurately subscribe a course of treatment,” he said, noting the annual cost of wasted prescription drugs not taken by patients. “The doctor is able to see your pill bottle and what medications you take and don’t take.”

The Heal service offers in-house doctors’ visits throughout California for a $99 fee. Heal doctors see about 15 patients a day, versus the typical doctor’s schedule which average around 40 patients a day, said Desai. The company has about 12 full time doctors but is looking to expand to nearly 30 by January, he added.

Sometimes the startup’s doctors will treat more than one person per visit, often children and parents together, said Desai, adding, “The number one group we have right now as users are adults who are ages 32 to 48 with young children.”

Other investors in Heal’s Series A round included Breyer Capital Qualcomm Executive Chairman Paul Jacobs, and early investors Hashtag One, March Capital Partners, and Slow Ventures. The startup has raised $40 million in total.
