AppNexus, a New York City-based real-time ad platform for global ad networks, demand-side platforms (DSPs), and other online advertising companies, has raised $50m in Series C funding.
Investors include all Series B venture capital backers Venrock, Kodiak Venture Partners and First Round Capital. Microsoft, a longstanding AppNexus client, also joins as an investor.
The company will use the funds to further invest in its technology infrastructure, new product development, and continued global expansion.
AppNexus provides single-point buying access to the major real-time ad exchange offerings like those available through Google and Microsoft, and to other major inventory aggregators.
In addition, the company provides a comprehensive set of ad management capabilities for executing and optimizing both real-time and directly negotiated media buys.
