Fuse Secures $25M to Revolutionize Outdated Loan Systems for Credit Unions with Powerful AI

In a significant move to modernize the backbone of American lending, fintech startup Fuse announced a $25 million Series A funding round on Monday, June 9, 2025, in Boston, MA. The capital infusion, led by Footwork with participation from Primary Venture Partners, NextView Ventures, and Commerce Ventures, fuels the company’s mission to disrupt the aging loan origination systems (LOS) that thousands of U.S. credit unions rely on. Consequently, this investment highlights a growing venture capital trend targeting foundational financial technology ripe for AI-powered transformation.

Fuse Targets a Critical Gap in Credit Union Technology

A loan origination system serves as the primary system of record for lenders. Importantly, it manages the entire loan lifecycle from application to disbursement. However, legacy LOS platforms, often provided by companies like nCino and MeridianLink, present substantial operational hurdles. Traditionally, these systems require lengthy integration periods, sometimes lasting up to a year. Furthermore, they lock institutions into multi-year, expensive contracts that stifle innovation and flexibility.

Fuse co-founders Andres Klaric and Marc Escapa identified this pain point firsthand. After three years building an automotive lending startup, they recognized the transformative potential of large language models (LLMs). “We realized that LLMs could modernize something even more significant,” Klaric explained. Their subsequent pivot led to the creation of Fuse, an AI-native LOS designed from the ground up to leverage artificial intelligence. The platform aims to help lenders process higher volumes, automate complex underwriting tasks, and dramatically reduce operational costs.

The $5 Million “Rescue Fund” for Credit Unions

To accelerate adoption, Fuse has launched an aggressive onboarding program. The company is allocating $5 million from its new funding as a “rescue fund.” This initiative offers the first 50 qualifying credit unions free access to the Fuse platform. Crucially, this access continues until their existing contracts with legacy LOS vendors expire. Klaric emphasized this is not a marketing gimmick. “Because legacy software costs are high, many credit unions cannot afford to break their current contracts to switch providers,” he stated. This strategy directly addresses the financial inertia that keeps institutions tied to outdated technology.

Investors See a Massive Market Opportunity for AI in Lending

The investor rationale for backing Fuse is clear. Nikhil Basu Trivedi, a co-founder and general partner at lead investor Footwork, pointed to the vast, underserved market. “We know the credit unions are really hurting and want to adopt AI, but have no idea how to do it,” he told Bitcoin World. With over 4,000 credit unions in the United States, the demand for technological overhaul is immense. Basu Trivedi compared the LOS to an enterprise resource planning (ERP) or customer relationship management (CRM) system. He noted it is equally vital for daily credit union operations.

The challenge of swapping an LOS has historically been monumental. Yet, Fuse promises a relatively quick adoption curve, a claim common among new AI-driven enterprise software startups. The company already boasts over 100 customers, validating early market traction. However, Fuse is not operating in a vacuum. It faces competition from other AI-infused LOS startups like Casca and Glide, indicating a burgeoning sector within fintech.

Mission-Driven Focus on the American Middle Class

Beyond pure technology, Klaric articulates a mission-driven purpose for Fuse. He strongly believes in helping credit unions reduce costs because these institutions primarily serve the American middle class. “Credit unions and smaller financial institutions have everything required to win,” Klaric said. “They have the local presence, the local focus, great member experience. They even have branches in very good locations. The only thing they don’t really have is the right technology.” This perspective frames Fuse’s offering not just as a software sale, but as an empowerment tool for community-focused finance.

The Broader Context: AI Reshapes Financial Services Infrastructure

The funding for Fuse arrives amid a wave of AI investment reshaping core financial infrastructure. Legacy systems in banking, built on decades-old code, are increasingly seen as liabilities. They struggle with scalability, data integration, and user experience. Modern AI-native platforms promise agility, deeper insights through data analysis, and automated decision-making. This shift is particularly relevant for credit unions, which often lack the vast IT budgets of large national banks.

The potential impacts are multifaceted:

• Operational Efficiency: AI can automate manual underwriting checks and document processing, freeing staff for complex cases.
• Risk Assessment: Advanced algorithms can analyze alternative data for more nuanced credit decisions.
• Member Experience: Faster loan approvals and a streamlined digital application process improve customer satisfaction.
• Cost Structure: Reducing reliance on manual processes and expensive legacy maintenance can improve margins.

Expert Analysis on the LOS Market Evolution

Industry analysts observe that the LOS market is at an inflection point. For years, innovation was incremental. The integration of generative AI and machine learning represents a step-change. Startups like Fuse are betting that a cloud-native, API-first, and AI-core architecture provides an insurmountable advantage. This architecture allows for continuous updates and easier integration with other modern fintech tools. The key challenge for Fuse will be demonstrating robust security, regulatory compliance, and reliability to gain the trust of risk-averse financial institutions.

Conclusion

Fuse’s $25 million Series A funding marks a pivotal step in the modernization of lending technology for credit unions. By leveraging an AI-native loan origination system, the startup directly confronts the high costs and rigidity of legacy software. Its innovative “rescue fund” strategy tackles the significant barrier of existing contracts. Ultimately, the success of Fuse and its competitors will be measured by their ability to deliver tangible efficiency gains, risk improvements, and enhanced member service for the thousands of community-focused credit unions across the United States. The race to redefine the backbone of lending is now decisively underway.

FAQs

Q1: What is a Loan Origination System (LOS)?
A Loan Origination System is the core software platform lenders use to manage the entire loan process. This includes application intake, credit underwriting, approval, documentation, and fund disbursement.

Q2: Why are legacy LOS platforms problematic for credit unions?
Legacy systems often have lengthy implementation times, costly multi-year contracts, and outdated architectures. They lack flexibility, making it difficult to integrate new tools or adapt to changing market demands, thereby hindering innovation and efficiency.

Q3: How does Fuse’s AI-native platform differ from traditional LOS software?
Fuse is built from the ground up with artificial intelligence and large language models at its core. This design aims to automate complex underwriting tasks, process applications faster, and provide more intelligent data analysis compared to rule-based legacy systems.

Q4: What is the purpose of Fuse’s $5 million “rescue fund”?
The rescue fund is designed to remove the financial barrier for credit unions stuck in long-term contracts with legacy vendors. It offers qualifying institutions free access to Fuse’s platform until their current contracts expire, enabling a switch without penalty.

Q5: Who are Fuse’s main competitors in the AI lending software space?
Fuse competes with other startups like Casca and Glide that are also developing AI-infused loan origination systems. It also aims to displace established legacy providers such as the publicly traded nCino and private-equity-owned MeridianLink.
