BankMobile is aiming to help its millennial customers start investing via an upcoming partnership with free stock-trading service Robinhood.

The mobile-first arm of Phoenixville, Pa.-based Customers Bank, BankMobile is just under a year old but has already made its name a byword for innovation and experimentation.

It has brand ambassadors on college campuses, street campaigns in the big cities, and offers a full-featured mobile app that includes, perhaps uniquely for mobile-only banks, a credit component.

In August, the bank also launched its own technology company, BankMobile Technologies, in a move reminiscent of CBW Bank and Yantra Financial Technologies.

But another major arrow in the bank’s quiver is partnerships. Customers Bank, BankMobile’s parent, inked a deal with business loan marketplace Biz2Credit for small business loans in October. Last month in Tel Aviv at Bank Innovation Israel, Luvleen Sidhu revealed BankMobile had its own partnership in mind: free stock-trading app Robinhood.

Jay Sidhu praised Robinhood this summer as a company that had “cracked the code” of attracting millennials, which is the trick BankMobile itself hopes to achieve. Robinhood grew rapidly and won the affection of millennials with its commission-free stock trades. Its waiting list grew to 500,000 just a few months after launch.
