    Bill Warner is a serial entrepreneur who founded Avid Technology and Wildfire Communications. Since 2000, Bill has focused on helping entrepreneurs through mentoring, angel investments, and as a long-time trustee of the Massachusetts Technology Leadership Council. Co-Flow Investing, LLC is Warner's entity for direct investing in early stage entrepreneurs. This is for Warner's personal investments and he does not have outside investors. Warner prefers investments of about $25,000, and generally likes to be the very first money into the company. Warner is willing (and even prefers) investing so early that the only traction is in the entrepreneur's head. He chooses his investments based mainly on the entrepreneur, and not on the details of the idea. Warner is also an investor and mentor with TechStars Boston (see profile). He also operates an Accelerator inside the Cambridge Innovation Center (see profile). The Anything Goes Accelerator Lab, will not take equity in the startups it admits, and it will not evaluate candidates based on business plans. The program's 80-or-so so slots will be filled by founder teams that show potential. Each will pay $350 a month for three months to get office space in the CIC's co-working environment, access to tools developed by Warner and colleagues, and a network of informal mentors.
