With 300 fintech innovators already taking advantage of Yodlee’s 10-month old accelerator program, the company’s sights are set on still more companies coming on board. In fact, Yodlee anticipates growth of more than 50% by the end of the year.

One of the key features of the program is free access to Yodlee’s API, which brings with it the ability to draw from a wealth of financial data, from bank accounts to rewards campaigns. Program companies have taken this data and run with it, building everything from eWallets to new lending services.

Aside from its role in “paying it forward” (fintech edition), Yodlee has been a very successful outfit in its own right. The company has more than 40 million users and $100 million in capital, with 20% of its customers coming from outside the United States.

It’s worth pointing out that Yodlee’s accelerated startups include a handful of Finovate alumni such as EZBOB and FreeAgent (both companies fresh from appearances at FinovateEurope). Other alumni taking advantage of Yodlee’s platform include Credit Karma, Xero, and LearnVest.

Success with the accelerator program, which was launched in May 2012, may be what has encouraged the company to launch its API incubator program to cater to a different subset of startups. So far, Yodlee has been able to incubate 10 companies, including Finovate alumn, Planwise.

Yodless was last on the Finovate stage in September 2012 as part of FinovateFall in New York. Watch a demo of Yodlee in action here, as they present their small business platform.
