Andreessen Horowitz has invested more than $80 million in Twitter via purchasing stock in secondary markets.
When called about it by BoomTown, a spokeswoman at the high-profile Silicon Valley venture firm confirmed the purchase.
The move is an interesting one, since Andreessen Horowitz was not part of the recent $200 million round on venture funding at the San Francisco microblogging company, led by Kleiner Perkins and which valued it at $3.75 billion.
