FORTUNE — Venture capital firm Andreessen Horowitz today announced that it has closed its fourth fund with $1.5 billion in capital commitments.
This is the same fund Fortune reported on back in January, which at the time was already said to be oversubscribed.
In a blog post announcing the close, A16Z partner and chief operating officer Scott Kupor refers to this as a “multi-stage venture capital fund,” but it’s actually two different funds that can work in parallel with one another. The main early-stage fund was capped at $1 billion, while a $500 million side fund can be used for larger opportunities (i.e., GitHub, Skype, etc.).
From Kupor’s blog post:
Andreessen Horowitz portfolio companies include Actifio, AirBNB, Box, DataGravity, Lyft and Pinterest. It also led a $75 million round last December for Oculus VR, which this week agreed to be acquired by Facebook (FB) for more than $2 billion.
