Skype cofounders Niklas Zennström and Janus Friis have raised $165 million for their second venture fund which will mainly back European high growth tech startups. Zennström and Friis—who also started Kazaa and Joost—had initially aimed to raise $266 million for the fund a year ago but downplay the shortfall telling the Financial Times, “when we started we had a flexible number” and “we think we have exactly the right amount of money.”

Zennström and Friis started their investment comapny—Atomico Ventures—four years ago. Over the last year, it has backed several startups, including mobile gaming firm Zattikka, music service Rdio, and social games site Playfire.

In its announcement, Atomico loosely lays out the criteria for how it will use the new cash. Zennström: “We will seek to invest in exceptional entrepreneurs who are building exceptional businesses. We will target companies that we believe have the potential to generate significant growth, transform their industries, and deliver strong returns.”
