Brad Feld (Managing Partner at Foundry Group) blogs about his firm's experience of running a syndicate on AngelList and why they are stopping the experiment.
Ultimately, we’ve decided that the effort that we are putting into FG Angels is too great for us to continue on in the way that we’ve have been for the past two years. However, by running the experiment, we’ve better understood the leverage points at the angel / seed level that AngelList and Syndicates create, which for some investors, and many entrepreneurs, is very powerful. Finally, we’d like to believe that we’ve contributed to the evolution and dynamic of angel / seed investing through this effort. While we are no longer going to be actively making FG Angels investments, every now and then we might do something out of FG Angels. We continue to believe that AngelList Syndicates is an effective platform for companies and investors.
