Per JJ Maclean (GP, Side Door Ventures): "We rarely lead rounds but co-invest alongside trusted venture partners out of 4 funds. Our Opportunity Fund is a permanent capital vehicle regularly writing 15-20 checks annually ($1M-$8M per ticket). Our $30M Seed Fund typically writes 10-12 first checks per year with 75% earmarked for follow-on investments. The $20M web3/blockchain fund invests first checks of $250K into 20 companies per year. Last, our YC Fund has only YC Alumni LPs and invests strictly in current YC companies where our network can be most helpful."
