1) RightCare, a Horsham patient-evaluation software maker, has raised $4 million from NewSpring Capital, Radnor, to build a national sales and marketing system. RightCare, which says it developed its Discharge Decision Support System (D2S2) software "through a decade of research" at Penn's Nursing school, was founded by CEO Eric Heil and Dr. Kathy Bowles. As part of the deal, NewSpring's Brian G. Murphy joins the RightCare board.

3) Cloudnexa, a Navy Yard-based cloud managed services provider that's an authorized reseller in the Amazon Web Services (AWS) Partner Network, says it has struck a deal with machine-data specialist Sumo Logic, security software maker TrendMicro and business software monitor AppDynamics to market a joint solution to government, healthcare, construction and other AWS clients. The deal allows the companies "to bundle with our managed-services solution," Cloudnexa chief executive Joel Davne told me. "A key part was getting them to convert their existing pricing models into utility pricing," with no lock-in requirement, "so they don't get soaked with professional service fees from traditional system integrators. It positions us nicely to meet more customer requirements." The company employ 15 and expects rising sales and a new investment round will fuel growth.

Picwell claims a string of Penn professors who specialize in business and healthcare -- Jonathan Kolstad and Robert Town at Wharton, Tom Baker at Penn Law -- as part of its "executive team," along with Wharton grad Anirudh Vemprala, Picwell's chief technology officer.
