Delfi has secured a strategic investment from Members 1st Federal Credit Union as the New York-based fintech expands its artificial intelligence-powered balance sheet management technology for financial institutions. The investment was made through Delfi’s Credit Union Service Organization, or CUSO, which is designed to bring advanced financial analytics and capital markets capabilities to credit unions. Financial terms of the transaction were not disclosed.
Expanding Delfi’s Credit Union Strategy
Members 1st is a member-owned financial institution serving more than 630,000 members and managing approximately $8 billion in assets, giving Delfi a significant strategic partner within the credit union sector. The Pennsylvania-based organization invests in fintech companies and CUSOs that can improve financial performance, operational capabilities, and value delivered to credit union members. Its backing of Delfi reflects a broader effort to give credit unions access to sophisticated technology traditionally associated with larger financial institutions.
Delfi CEO and co-founder Daniel Ahn said stronger balance sheet decisions can generate additional earnings and capital that credit unions can ultimately redirect toward their members and broader missions. The company intends to work with Members 1st and other credit unions to further develop tools tailored to the financial and operational requirements of member-owned institutions. Members 1st Chief Revenue Officer Stuart Bretz highlighted Delfi’s ability to support proactive risk identification, financial oversight, and more informed institutional decision-making.
AI-Powered Balance Sheet Management
Delfi has developed an AI-native platform that enables banks and credit unions to analyze their balance sheets, test financial scenarios, manage risk, and identify potential capital markets opportunities. Its technology combines balance sheet intelligence with execution capabilities, allowing institutions to move from financial analysis toward actionable decisions within a single platform. The company positions the system as an alternative to fragmented financial tools and processes that can make institutional balance sheet management more complex.
The platform includes Overwatch Essentials, which supports balance sheet analysis, scenario testing, and reporting, alongside Overwatch Predictive, which provides more advanced probabilistic modeling and scenario analysis. Delfi Exchange connects insights generated through the platform with selected capital markets opportunities and transaction execution, extending the product beyond financial analytics alone. Delfi has also introduced an AI Agent that allows users to interact with financial data, interpret outputs from its economic models, and generate recommendations using natural-language queries.
Building Momentum Across Credit Unions
The investment follows Delfi’s launch of its CUSO earlier in 2026 alongside One Washington Financial and Maps Credit Union, marking an increased focus on serving the credit union market. Since then, the company says it has facilitated approximately $100 million in transactions through its platform while expanding integrations with credit union balance sheet planning processes. Delfi has also participated in industry initiatives including the Filene Research Institute’s FiLab program and the Circuit Accelerator.
For Delfi, the Members 1st partnership provides both capital and direct strategic involvement from a large credit union as it develops products for the sector. This structure can give the company deeper insight into how credit unions approach areas including liquidity, interest-rate exposure, financial forecasting, capital allocation, and long-term balance sheet planning. It also gives Members 1st an opportunity to participate in the development of technology intended to strengthen decision-making across the wider credit union ecosystem.
The strategic investment from Members 1st strengthens Delfi’s position as it seeks to expand AI-driven financial decision-making technology across banks and credit unions. By combining balance sheet analytics, predictive modeling, natural-language AI capabilities, and capital markets execution, the company is building a platform intended to help financial institutions respond more effectively to changing market conditions. The partnership also highlights growing interest among credit unions in supporting fintech infrastructure that can improve financial resilience while generating greater value for their members.
