When Krishnan Ganesh’s father-in-law was diagnosed with cancer two years ago, Ganesh had to “run from pillar to post” to get quality medical care at home, a concept that is not prevalent in India. That’s when he hit upon the idea of a home healthcare service.

The Bangalore-based entrepreneur, who founded online tutoring company TutorVista in 2005 and sold it to British publisher Pearson for $213 million, then bought start-up Portea Medical in July 2013.

Portea Medical and start-ups such as Health Care at Home India, Homital and India Home Health Care provide at-home services ranging from geriatric and post-surgery care to physiotherapy and general doctor visits.

“Demand is large and technology can be used for innovation and disrupting the status quo, and basically address a large problem like we had done in TutorVista for education,” Ganesh said.

India’s home healthcare industry, which consists of home-based medical devices and home services, is worth $2 billion and growing at 20 percent annually, according to accounting firm PricewaterhouseCoopers (PwC).
