Turning Complex Insurance Logic into a Business-Critical Digital Client Portal

Meet the Client

Paratus is a specialist insurance provider operating at the intersection of renewable energy, infrastructure and complex risk modelling.

The organisation underwrites highly technical assets, including solar farms and emerging energy projects, where financial performance is driven by detailed assumptions, market variables and carefully constructed risk models.

Paratus’ competitive advantage centres on proprietary calculation methodologies. Their protected pricing frameworks, projection engines, and modelling tools underpin business operations and drive differentiation in a competitive market.

As the company grew, leadership determined that Paratus’ digital engagement must fully reflect its technical capabilities. Sonin’s partnership enabled this vision, creating a unified client portal alongside broker and consumer websites and an internal intranet, each tailored for its target audience yet upholding rigorous standards of quality and operational precision.

Key Features

Secure KYC Digital Onboarding – Clients complete structured Know Your Customer forms directly in the portal, eliminating manual documentation and streamlining onboarding.

IRR and Scenario Modelling Tools – Users can model renewable energy investments by adjusting market variables and viewing projected returns in real time. Complex financial assumptions are translated into intuitive visual outputs.

API-Driven Insurance Calculators – Front-end components integrate with proprietary back-end APIs, ensuring accuracy while maintaining strict protection of intellectual property.

Enterprise-Grade Authentication – Robust identity management and secure access controls provide confidence without compromising usability.

Responsive Data Visualisation – Rather than simplifying or removing complex charts on smaller devices, Sonin redesigned their presentation to ensure clarity and usability across desktop and mobile environments.

High-Performance React and Next.js Architecture – The portal achieved Lighthouse benchmark scores of 100 across performance, accessibility, best practices and SEO, a standard rarely reached in data-driven financial platforms.
