The deal will allow Yodlee to offer its technology on the Personal Finance channel of AOL's subscription service, as well as on CompuServe and Netscape's Netcenter Web portal.
AOL representatives declined to comment on the deal.
Yodlee lets users create personalized account information on a single page. When a person enters a password, Yodlee aggregates summaries of personal information from bank accounts, credit cards and other sources.
"Consumers want a way to manage all their personalized content and activities from one trusted Web site," Anil Arora, chief executive of Yodlee.com, said in a statement. "Together, Yodlee.com and America Online will work to deliver the ultimate personal experience."
For Yodlee, the deal comes months after it inked similar agreements with 17 other companies, including Web portal AltaVista, personal finance software maker Intuit, and Sabre Business Travel Solutions. The company's main competitor is VerticalOne, which also offers account aggregation services for Web sites and has signed deals with CNBC, iVillage, Ameritrade's OnMoney, Go Network, MotleyFool and several others.
AOL adds Yodlee to a list of partnerships as it works to further enhance its services. The company also is testing new versions of its proprietary software and a satellite broadband offering with Hughes Electronics' DirecPC.
AOL is in the process of acquiring media and entertainment giant Time Warner in a multibillion-dollar deal. Executives expect the acquisition to close by year's end.
