here's a rough summary of my track record (personal / professional)
1) my angel investments ($300K portfolio, 2004-2008 vintage): 3 exits (Mint, Mashery, SlideShare) @ $100M+ out of 13 -- roughly 3.5X cash on cash in ~8 years
2) my investments at Founders Fund (~$3M portfolio, 2008-2010): 3 unicorns (Credit Karma, Lyft/ZimRide, Twilio) + 3 large wins (Wildfire, SendGrid, Life360) out of ~40 investments via FF Angel + fbFund -- roughly $50-60M appreciation in value over 7-8 years, >100% Gross IRR
3) 500 Startups main funds: $30M Fund I / 265 companies / 19% Net IRR / 2010-11 vintage, $45M Fund II / 325 companies / 23% Net IRR / 2012-13 vintage -- so far, 2 unicorns (Twilio, Credit Karma), 2 half-unicorns (Ipsy, Udemy), 30+ "centaurs" (>$100M+ value). Fund III is $85M / vintage 2014-15 / 650+ companies -- still pretty early but so far Net IRR trending ~20%
our LPs have been happy with our results so far. my/our track record is likely upper quartile, and at least for my years at Founders Fund top decile. Peter and I may differ in approach & stage, but likely more in agreement than not about the #s, altho he would likely consider or strategy more brute force and inelegant than his. that said, I think made enough money for him at FF & found him 3 unicorns, so hopefully he doesn't think I'm an idiot ;)
Good question - we don't have much IRR data on 500 Startups' funds (most of them are still open), but they never have trouble raising more money for new funds, so I assume their LPs are happy.
