I invest in, and/or consult to, early stage technology startups, particularly in AI but also other areas.  I am often the first money in, and usually am very active as a strategic advisor as well as assisting with introductions to adjacent founders, angel investors, potential employees, and/or potential venture capital investors.  When I invest, I also sometimes have advisory stock (options on common) in addition to pure investment.  In other cases, I am solely an advisor.
