Zillion Group, based in Norwalk, has $28 million in new capital commitments, with the Norwalk-based company’s platform allowing doctors and insurance companies to use video, text messages and other means to connect with patients.

Under the “Ready. Set. Engage.” slogan, Zillion designed its platform to help health providers engage patients on the smartphones and tablets they use in their everyday lives.

That includes not just physicians or insurers like UnitedHealth Group, but also the makers of sophisticated medical devices like Apollo Endosurgery to help them coach patients directly, with Apollo selling the Orbera balloon to help obese people lose weight.
