Challenge

Building a Complex Fintech Product Without Slowing Down

Loanbook — a global B2B fintech platform — set out to transform how financial institutions lend, invest, and trade in the secondary loan market. Their goal: create a digital marketplace where banks, NBFCs, and institutional investors could seamlessly connect and transact.

To bring this to life, they needed to:

Build a cross-functional engineering team experienced in complex fintech workflows

Accelerate development of a scalable MVP for their core product, XChange

Operate lean without compromising on backend robustness or frontend polish

Avoid the long ramp-up times and overheads of traditional hiring

With time-to-market and domain depth both critical, they needed more than just freelancers or contractors — they needed engineers who could take ownership.

Solution

01 | A Custom-Built Tech Team, Ready in 6 Weeks

Expertise on demand — not outsourced execution

Loanbook had product vision, a strong founding team, and deep market insight. What they lacked was the right development muscle — engineers who could build complex transaction logic, interface with financial institutions, and ship production-grade software, fast.

M91 assembled a blended team of full-stack developers, product engineers, and frontend specialists. Our structured hiring process ensured alignment with both their tech stack and product complexity — with a strong focus on Python, React, and fintech-specific patterns like custodian accounts and transaction ledgers.

The team was reviewed and selected by Loanbook's internal leadership. Once hired, they worked directly under Loanbook’s CTO, integrating seamlessly into their roadmap and daily rituals.

02 | Engineering Enablement Without Operational Drag

All focus on product. No distraction from delivery.

From day one, our goal was to support — not override — Loanbook’s internal processes. We provided ready-to-code engineers who could adapt quickly, pick up financial workflows fast, and work directly with product leads.

Each engineer joined with access to structured onboarding materials, infra support, and sprint-level clarity. Whether integrating with SWIFT protocols, enabling multi-stakeholder account logic, or supporting data visualization dashboards — the team delivered without slowdowns or extra layers.

We also supported platform evolution — contributing to features like:

Partner bank onboarding workflows

Deposition & custodian account logic

Real-time offer visibility & negotiation modules

Marketplace intelligence through data-led APIs

All while keeping the IP and velocity fully in Loanbook’s hands.

Key Results & Long-Term Wins

MVP Built in Half the Time

What could’ve taken 4+ months with local hiring or distributed contractors, took just 6 weeks to get started — with an MVP release that hit deadlines and investor expectations.

Team That Owns Delivery

Every engineer worked as part of Loanbook’s internal rhythm — reporting to their CTO, participating in planning, and building for outcomes. No dependency loops. No misalignment.

Lean, Scalable Execution

With our engineering support, Loanbook scaled tech without bloating the core team. That meant fewer distractions, better focus on product-market fit, and faster iterations on mission-critical features.
