The only original IRR which was semi-published was the first fund (300 mil). If I recall it was a 200 ish % because of Nicira, Skype, Instagram, and FusionIO.

The only original IRR which was semi-published was the first fund (300 mil). If I recall it was a 200 ish % because of Nicira, Skype, Instagram, and FusionIO. You can get somewhat of an idea of the IPOs and acquisitions here: https://www.crunchbase.com/organization/andreessen-horowitz/exits https://www.crunchbase.com/organization/andreessen-horowitz/... I would expect the IRR is quite good as the follow up funds tend to be oversubscribed and are full of original LPs. As to the expenses...the marketing is quite inexpensive and has more than paid for itself. No idea on the costs around the services to the portfolio companies. Full disclosure: I've worked for quite a few of their portfolio companies.
