How Credit Unions Can Steal SoFi’s Playbook
A Guide to Member Acquisition, Relationship Depth, and Long-Term Value
SoFi built a $38 billion deposit franchise by turning student lending into a relationship strategy. New research from Cornerstone Advisors and LendKey reveals how SoFi turned student lending into a growth engine powering 13.6 million members and $38 billion in deposits—and why credit unions are well-positioned to replicate and outperform that model.
Drawing on survey data from nearly 1,200 SoFi members and 9,300 U.S. consumers, the report explores the acquisition, cross-sell, deposit, and loyalty strategies behind SoFi's success. It also highlights how changes in the federal student lending market are creating a new opportunity for credit unions to attract younger members, deepen relationships, and drive long-term growth.
What You’ll Learn in This Report
- Education financing is a relationship strategy, not just a lending product. SoFi used student lending as a gateway to broader, long-term member relationships.
- The next member growth opportunity is emerging now. Federal student lending changes are creating new demand for private lending and refinancing solutions.
- Trust, convenience, and personalization drive deposit growth. Competitive rates matter, but experience and proactive engagement matter just as much.
- Credit unions already have the brand advantage. The biggest gap isn't trust—it's execution across digital experience, onboarding, cross-sell, and member engagement.
