Raj Date, the former deputy director of the Consumer Financial Protection Bureau, appears to be a Bitcoin believer.

Date, who helped start the CFPB and served as special advisor to then-Treasury Secretary Timothy Geithner, has joined the board of digital currency startup Circle Internet Financial in Boston, according to a press release Thursday.

"Products that use digital currency have the potential to remove significant friction from our financial lives, and to expand financial inclusion for the underbanked around the world," Date said in the release. "Circle is well-positioned to lead innovation in the space and to champion mainstream adoption of promising new technologies like Bitcoin."

Circle Financial touted Date's appointment as evidence of its commitment to consumer protection, privacy and regulatory compliance.

"As an executive who has worked in both industry and government leadership positions within consumer finance, [Date] brings Circle incredible perspective and vision," Jeremy Allaire, Circle's chairman and chief executive officer, said in the release.

Date founded Fenway Summer, a financial advisory and investment firm, after stepping down from his position at the CFPB earlier this year. He has also served as managing director in the financial institutions group at Deutsche Bank Securities and as senior vice president for corporate strategy and development at Capital One Financial (COF).
