How to transition to the venture side of startups?

A lot of the people in venture have come up through the traditional finance/consulting ranks with 0 operational experience or have been very successful founders. If you're not one of these, your best hope is to get an EIR role and prove high ROI for a fund. The other way is to be a successful angel for a decade and hope that your track record allows you to become a partner at a smaller firm. Angelist syndicates can help you start such an endeavor.

Don't. There's enough shitty ass people on the finance side. Make your company work, then invest in good companies later.
