CFA?

Well, no doubt it would be a plus given your IT background. Having a genuine interest in finance and holding a certification that supports some of the "basic" functions of finance will definitely go a long way to show that you really want to be successful, but a CFA isn't required to get into the VC industry. The most important thing would be having contacts and/or alumni in the industry in order to get your foot in the door. It's hard to say just how useful it will be because each firm would be subjective to the firm's focus, but I would think a CFA would be most useful in investment banking, then private equity, then VC (being last).

Some firm's focus on practically nonexistent companies (start-ups), so there would be little, if any financial analysis that needed to be performed. Other's look at later stage ventures where there might be a bit more analysis done, but VCs are generally looking to invest in a great idea and often disregard or discount the finances of the company because the company is usually in it's infancy.

Essentially, I don't think it will really help you break-in but having the IT background and holding the CFA designation would/could be what a VC is looking for, if you find the right one. Good luck to you.
