Atomico, which began raising its fourth fund eleven months ago, has closed it with $765 million making it one of the Europe's single largest venture capital funds.

While it is a huge step up from Atomico's third fund which was closed with $476.6 million in 2013, TechCrunch reports that the company's pace of fundraising highlights a major difference between Europe and the U.S. where LPs often feel pressured while committing quickly to top funds. Atomico's current stakes include the popular Finnish game maker Rovio, the travel site GoEuro and the "unicorn" payments company Klarna.

The U.S. has a "much longer tradition" of investing in venture capital firms, notes the general partner Mattias Ljungman and on the other hand, institutions in Europe are only "sort of now starting to look at it".

According to Atomico, originally founded by the Skype cofounder Niklas Zennstrom, European venture capital has the potential to reach the same kind of breakout velocity at some point. Meanwhile, the firm is currently one of the best-funded firms in Europe, its central office being in London but people working in different countries including Tokyo, Beijing, Sao Paulo, New York and Stockholm. The firm also offers services to its portfolio companies.

Over the years, the firm has developed a platform with an in-house "value creation team" which includes seven partners who advise on things like marketing and communications and support the firm's eight full-time partners. The firm also employs various associates, advisors and a head of research. Also, a healthy percentage of its employees are women.

As told by Ljungman, Atomico's limited partner base is made up of pension funds and sovereign wealth funds. A small but growing percentage of its relationships are with companies that see the firm as a bridge between older and new parts of the economy and want to better understand how technology would disrupt their businesses before it happens.
