A new fintech partnership offers new and innovative ideas for credit unions.

Reseda Group, a wholly owned CUSO of Michigan State University Federal Credit Union (MSUFCU), announced it has acquired Tandem, an Ann Arbor, Mich.-based fintech app that helps couples manage shared finances. The deal reflects Reseda Group’s strategy to build an integrated family banking ecosystem serving every stage of financial life.

Tandem, co-founded by Michelle Winterfield and Dan Couvreur, enables users to easily plan, spend and split expenses. The platform manages hundreds of millions of dollars in shared costs and has become a favorite among Gen Z and millennial couples seeking a more transparent, modern approach to joint money management.

“We built Tandem to make managing money together easier and less stressful,” Winterfield said. “Joining Reseda Group allows us to expand our mission — from couples to families and helping people navigate every stage of shared financial life.”

Reseda Group was an early investor in Tandem and now brings the app fully into its portfolio. The move supports MSUFCU’s broader digital banking vision, connecting individual, joint and dependent accounts into a single family-focused experience.

“With Tandem now part of our ecosystem, we’re advancing a more collaborative and transparent digital banking model,” April Clobes, president/CEO of Reseda Group and MSUFCU, said.

Winterfield and Couvreur will join Reseda Group as vice presidents to continue developing Tandem and future family banking products. The acquisition underscores credit unions’ growing investment in fintech partnerships to meet evolving member expectations for personalized, digital-first solutions.
