Entrepreneurs can’t sit still for long.

Four months after announcing his departure from Google Ventures (now GV), which he cofounded and led, Bill Maris is reportedly raising a fresh $230 million VC fund that will focus on healthcare investments.

News of the fund first leaked in September in an article on CNBC. Citing anonymous sources, it said Maris had “preliminary plans to raise between $350 million and $500 million, though no amount has been set.”
