Sphera, a Web-hosting software maker, attracted $20 million in its second round of financing, the company said Thursday. The round includes a $5 million infusion from Vision Capital and Bank of America Equity Partners, on top of the $15 million raised earlier in the round from lead investors TLcom Capital Partners and Jerusalem Venture Partners. Gemini Israel Funds also contributed. Sphera's main product, HostingDirector, helps automate the Web-hosting process and reduces costs, it said, by allowing customers to manage hosting services themselves.
