Just a week after Technology Crossover Ventures closed a $2.23-billion fund, venture capital giant Andreessen Horowitz has closed $1.5 billion for its fourth investment fund. Two years ago, the firm had raised another fund of the same size, according to The Wall Street Journal (WSJ).

Managing partner Scott Kupor said of the concentration of venture money among big companies: "The important thing is that the total number of dollars flowing into this industry is at a rational level. It's not so much about which firms can raise how much. The total dollar amount is more important than whether consolidation is good or bad. In 2000, it was like $110 billion. Now it's like $16 billion to $18 billion per year."

Kupor said the company can use up the remaining cash in its previous fund for a couple of investments before it taps the fourth fund, the report added.

Andreessen Horowitz has backed a varied group of businesses. This year, the firm has expressed interest in the 3D printing, drone tech, consumer mobile, bitcoin, and enterprise infrastructure industries, the report detailed.

The Silicon Valley-based venture capital firm was founded in 2009 by Marc Andreessen and Ben Horowitz. The company currently manages more than $4 billion, WSJ reported.
