Sunny Day Fund ☀️

About the Company

Sunny Day Fund delivers the leading financial wellness platform that automates and incentivizes workplace emergency savings. Experts predict 40-60% of all employers will offer emergency savings accounts as a benefit by 2026 driven by Secure Act 2.0, which passed because of growing 401(k) loans and hardship withdrawals and continued financial vulnerability. As a result of the benefit, employers have been able to realize ~10x take-up rate compared to a basic financial literacy application, ~25% higher retention within participants, and half as many 401(k) loans and early withdrawals. Sunny Day Fund especially empowers younger or low and middle-income workers who struggle to handle unexpected expenses or may be living paycheck to paycheck. Additionally, because Black, Latinx, and female workers have disproportionately taken 401(k) loans and early withdrawals, providing a payroll-deducted emergency savings program has become a DEI priority as well. Sunny Day Fund is a Certified MBE and has its SOC 2 Type II certification without qualifications.
