I have worked with Raj on a software project about 10 years back and we have been good friends since then. I have also spoken to his co-founder Dhrubo a couple of times. They bring a rare combination of deep domain knowledge in the healthcare industry with the required technical talent to build a great product. They can benefit tremendously from Techstar's help on product and fundraising. I have no hesitation in recommending them to Techstars.
