Introduction

RapidFi was founded with a mission to help millions of Americans access the healthcare they need—without being burdened by high insurance deductibles or upfront costs. The company set out to build a patient-first financing platform that would allow individuals to receive critical medical treatment today and pay over time with flexible terms.

As a young company tackling a heavily regulated space, RapidFi needed to move fast, stay compliant, and remain nimble enough to iterate their product as they learned from early customers. That’s where LendAPI stepped in.

Challenge

Like many upstart fintechs, RapidFi faced the classic hurdles of launching a lending product in a highly complex vertical: limited engineering bandwidth, the need for rapid deployment, and a lack of in-house expertise around compliance, infrastructure, and underwriting operations.

The founders didn’t have the time—or budget—to build their own decisioning engine, fraud tools, KYC/KYB workflows, or compliance infrastructure from scratch. At the same time, they couldn’t afford to make costly regulatory mistakes or delay time-to-market by waiting on long resource planning cycles and third-party vendor queues.

RapidFi also anticipated the need to pivot quickly, experiment with pricing and risk strategies, and support various partners across medical providers and insurance networks. Flexibility wasn’t a nice-to-have; it was essential.

Solution

LendAPI offered a complete solution to RapidFi’s technical and operational challenges through its industry-first “Do-It-Yourself and Launch-Yourself” fintech infrastructure platform. Designed from the ground up for fintech founders, LendAPI provided RapidFi with a plug-and-play foundation to build, deploy, and scale their lending product with full control and speed.

From day one, RapidFi leveraged LendAPI’s Rules Studio—a visual logic builder that allowed them to create complex underwriting and pricing models without relying on developers or DevOps teams. This flexibility meant that as their go-to-market strategy evolved, their product could too—without months of lead time.

Compliance and security were also built into the core of the platform. LendAPI provided versioning, decision logging, audit trails, and enforced policy controls out of the box. This allowed RapidFi to operate with the level of trust and transparency required in healthcare financing—without needing to hire a full-time compliance or infosec team.

In addition, RapidFi tapped into LendAPI’s fully integrated KYC and KYB tools to verify not only their business partners but also their end clients. Fraud prevention, identity verification, and onboarding workflows were fully operational with minimal lift—allowing the team to focus entirely on user growth and servicing patients.

Results

With LendAPI, RapidFi was able to go live in under 60 days—cutting months off of a traditional fintech product timeline. The platform’s flexibility allowed them to test and optimize pricing strategies and underwriting rules in real-time, without vendor backlogs or expensive change fees.

Most importantly, RapidFi stayed focused on their mission. Instead of getting distracted by infrastructure concerns, the team concentrated on building relationships with healthcare providers, improving user experience, and expanding access to care.

As RapidFi grows, LendAPI continues to serve as both a technology backbone and a compliance partner—providing ongoing guidance, tooling, and innovation to keep RapidFi competitive and secure in a complex regulatory environment.

Vivek Kumar, CEO of RapidFi, emphasized the importance of LendAPI’s role in their journey:

"Our mission at RapidFi is simple: we want to help millions of Americans access the care they need—without being trapped by high insurance deductibles or financial stress. LendAPI allowed us to stay focused on that mission. We didn’t have to worry about infrastructure, compliance, or tech—we just built what our customers needed."

Timothy Li, CEO of LendAPI, reflected on the broader impact:

"RapidFi is exactly the kind of startup we built LendAPI for. Fintech founders shouldn’t have to spend years and millions on tech, compliance, or risk infrastructure. LendAPI is the industry’s only DIY and Launch-Yourself FinTech Product Deployment platform. We're here to make sure the next generation of fintech startups—including those solving real problems like RapidFi—can launch faster, pivot smarter, and scale securely."
