About the Client
Raisal
Raisal is a fintech marketplace that transformed commercial real estate lending by connecting borrowers with specialized lenders through smart-matching technology.
Founded in 2014 and launched in January 2016, Raisal brought transparency to the traditionally opaque commercial mortgage industry, serving the $2.5 trillion CRE market with loan sizes from $500K to $10M.
In November 2019, TODO1 Services Inc. (iuvity) acquired Raisal, fully integrating the marketplace technology into their digital banking suite. Following the acquisition, CTO Fernando Rosario became Head of Engineering at TODO1/iuvity.

Goal & Outcome
Goal
Fernando Rosario's dilemma: Raisal's commercial mortgage marketplace was gaining traction in the $2.5 trillion CRE industry, but the React/Redux codebase was built by developers learning the framework. Technical debt was accumulating fast.
After 21 years at Accenture building financial software, Fernando knew what "maintainable code" really meant. The platform worked. Users loved it. But as the business scaled, every new feature took longer to build. The foundation wasn't built for long-term growth.
Commercial real estate financing is opaque and fragmented — borrowers seeking $500K-$10M loans had no visibility into competitive rates. Raisal was solving this with smart-matching technology connecting borrowers with specialized lenders nationwide. The product-market fit was proven. Now they needed enterprise-grade engineering to match.
Fernando needed senior React engineers who could modernize the platform without disrupting the business — not contractors who'd vanish, not agencies sending juniors after the sales pitch. He needed a team that understood fintech constraints and could write code that would last 5+ years without rewrites.
Outcome
We embedded senior React engineers as part of Raisal's core team through our dedicated team approach, establishing enterprise-grade architectural patterns from day one. Rather than building isolated features, we created a comprehensive component library with reusable UI blocks.
Our technical leadership extended beyond code. We coordinated with backend teams in Argentina, debugged cross-stack issues, and mentored Raisal's developers on React best practices — leaving them with not just working code but the knowledge to maintain and extend it.
The result: clean, maintainable React/Redux codebase with enterprise-grade architecture and zero technical debt.

Chief Technology Officer, Raisal
ProductCrafters worked well with our internal team and were very good at adjusting to our work style. They had a keen eye for detail and were very solution oriented. They thought holistically about solutions and brought up all-encompassing ideas.

Why Raisal Chose ProductCrafters
What made the difference in a crowded development market
Offshore Development Shops
- Timezone misalignment creates 24-hour delays for critical decisions
- Communication barriers lead to misunderstood requirements
- Junior developers gaining experience on your production codebase
Our Difference
Senior engineers (7+ years React/Redux) with overlap in US business hours for real-time collaboration. We led cross-timezone coordination with Raisal's Argentina backend team, turning potential communication gaps into smooth integration.
Large Development Agencies
- Senior architects sell the project, junior developers build it
- Agency overhead and bureaucracy slow decision-making for startups
- Fixed-bid contracts with change order friction
Our Difference
The engineers you meet are the ones who write your code. Lean 2-developer team with senior expertise, making decisions fast without layers of project managers. Monthly dedicated team rate with flexibility to adapt scope.
Independent Contractors
- Limited availability when urgent issues arise
- Inconsistent code patterns across multiple contractors
- No continuity through acquisition due diligence process
Our Difference
Embedded team model with long-term commitment. We stayed through Raisal's entire acquisition journey — from initial development through TODO1's technical due diligence — coordinating vendors and ensuring knowledge transfer to internal teams.
What Sealed the Decision
- ✓Fintech experience: Previous production deployments in lending, payments, and financial services
- ✓Senior-only team: 7+ years React/Redux production experience across financial applications
- ✓Technical leadership: Could architect frontend AND coordinate backend teams simultaneously
- ✓Transparent pricing: Fixed monthly dedicated team rate with no surprise bills or change orders
- ✓Long-term thinking: Clean architecture, comprehensive documentation, zero technical debt approach

FaQ
Can you build commercial mortgage marketplace platforms?
Yes, we specialize in fintech marketplace development for lending and financial services. We build platforms that connect borrowers with lenders through smart matching algorithms based on loan size, location, property type, and lending criteria—automating what is traditionally a manual process.
How do you ensure fintech code quality for acquisition due diligence?
We design systems with acquisition readiness in mind: clean architecture, maintainable code, and full documentation. Our approach includes secure authentication, encrypted data handling, audit logging, and infrastructure aligned with SOC compliance requirements.
What’s involved in building a two-sided marketplace?
Two-sided marketplaces require separate experiences for each user group. Borrowers need tools for submitting requests, uploading documents, and comparing offers, while lenders need discovery tools, filtering, evaluation workflows, and pipeline tracking—all built with intuitive UX.
Can small teams build enterprise fintech platforms?
Yes, with the right architecture. By using reusable components, strong engineering patterns, and focusing on high-impact features, small teams can deliver scalable fintech platforms without accumulating technical debt.
How do you coordinate multiple development vendors?
We establish clear API contracts, handle integration challenges proactively, and act as a bridge between teams. This ensures smooth collaboration across different vendors and time zones while maintaining development velocity.
What industries do you serve for marketplace development?
We build marketplaces across fintech, healthcare, real estate, and other industries, translating complex business requirements into intuitive and scalable digital products.
How long does it take to build a fintech marketplace?
Timelines depend on complexity. Platform rewrites can take around 6 months, while building full-featured fintech marketplaces from scratch typically requires 9–12 months with agile delivery and early prototypes.
What technologies do you use for fintech platforms?
We use React for frontend, Redux for state management, Node.js for backend services, PostgreSQL for data storage, and AWS for scalable infrastructure, following security best practices and OWASP guidelines.
