From Fragmented Tools to a Unified Fraud Prevention Platform

Four separate risk products. Four different interfaces. Bank teams toggling between all of them to assess a single borrower. I redesigned them into one unified decision engine — and validated the concept with seven banks before any production code was written.

The platform that wasn't a platform

Accumn is an AI-powered platform designed to help underwriters and risk management teams at banks and fintechs monitor borrower health and prevent fraud after a loan is disbursed. It's a significant product operating in a ₹30,520cr market.

The problem: it wasn't really one platform. It was four separate products — Explore, Insight, Fulfilment, and Risq — each built independently, each looking and behaving differently, and each requiring bank employees to sign in separately to get different data on the same borrower.

Four products, four separate UIs — a bank analyst assessing a single borrower had to context-switch between all of them.

Information without insight
The products surfaced data but didn't synthesize it. Spotting potential fraud required a user to mentally connect the dots across multiple screens.
Same borrower, four apps
Bank teams had to switch between multiple applications to build a complete picture of a single borrower's risk profile.
No brand consistency
Each product had its own visual language. There was no coherent system — just four things that happened to solve related problems.
No direct user access
Our research team had been let go. We were shipping features based on internal assumptions, with no feedback loop from actual bank users.
The situation became critical when our research team was let go. Our direct line to users was gone, and we were building new features based on guesswork — an unsustainable model that put the entire product line at risk.

Finding a way in

With no formal user research channel, I had to find an unconventional path to the people who actually used the product. The Sales team had the only direct access to clients — so I started there.

Rather than asking for favors, I offered value first. I noticed their presentation decks were outdated and weren't doing the products justice. I redesigned them. The gesture built trust, and that trust opened doors: I was invited to join client calls, and eventually an in-person visit with a major bank.

Redesigning the Sales team's presentations wasn't the brief — it was the move that earned access to real clients.

What I heard on those calls reframed the entire problem. Clients didn't need more data — they needed to understand the data they already had. The problem wasn't what the products could do; it was how they presented it.

Designing an insight-first decision engine

With that framing locked, I designed a unified platform from the ground up. The goal wasn't to merge four products into one for the sake of tidiness — it was to turn a data dump into a decision engine. Three guiding principles shaped every screen.

Show what's important first

The new dashboard leads with an Overall Risk Score — the most critical answer to the most critical question a bank employee has: "How risky is my portfolio right now?" Color and size communicate health at a glance, before the user has read a single number.

Visual-first analysis

I replaced dense spreadsheets with an interactive treemap that lets analysts explore their loan portfolio by industry, geography, or risk tier — and drill into problems with a single click. The chart does the synthesis that used to happen in the analyst's head.

Action-oriented borrower profiles

Each borrower profile now tells a story. The most critical signals — risk score, red flags, recent changes — lead. Supporting detail is available on demand. Users move through a borrower's profile in the order that matters for a decision, not the order the data arrived.

Validated before a line of code was written

Once the prototype was ready, it became our most powerful sales tool. The reaction from potential clients was immediate.

7 bank MOUs signed

Reflection

This project reinforced something I'd been learning: the designer's leverage isn't just in what they design — it's in who they talk to and how they earn those conversations.

Constraint breeds creativity
Losing the research team forced me to build a new path to users. That path — through Sales — turned out to be more strategically valuable than a conventional research program would have been.
Lead with value to influence
Helping the Sales team with their presentations wasn't a detour. It was the key that unlocked direct client access. To change what a team does, start by solving something they actually care about.
What I'd do differently
I'd involve engineering earlier on the interactive chart. The treemap visualization was technically complex, and surfacing those constraints sooner would have reduced risk in the build phase.
