AppNexus Raises $60M Round Valuing The Ad-Tech Company At $1.2B

Ad tech company AppNexus just announced that it has raised an additional $60 million.

The company said that the round, which could eventually reach $100 million, valued AppNexus at $1.2 billion. The money came from an unnamed “large, Boston-based public equity and asset management firm.”

Co-founder and CEO Brian O’Kelley told AdAge that the company just saw its first profitable quarter, and that the recent, underwhelming performance of ad-tech companies on the public markets didn’t factor into his decision to raise the money.

O’Kelley and his team┬áhave built a platform for buying and selling ads through real-time bidding. The company says 30 billion ad impressions are transacted on the platform each day, with more than $1 billion in ad spend on the platform in 2013. AppNexus also said it has nearly 600 employees.

This brings the total capital invested in the company to just over $200 million. A few months ago, the Wall Street Journal reported that Alibaba was one of several potential investors.
