Case studies
From high-performance marketing sites to full SaaS platforms — see what we've built for clients across the UK.
Custom Software DevelopmentDonation Management System (DMS)
We built Insyte for CFP Lottery & Raffles: a Django platform that ingests scanned donation forms, extracts them with Document AI, routes them through human QA, processes payments, reconciles banking and generates thank-you letters — with a read-only portal for the charities it serves.
Custom Software DevelopmentCharity SaaS Portal
We built the With Thanks portal: a charity platform that automatically produces personalised thank-you videos for donors, delivers them by email, and measures opens, clicks, plays and watch-time — with a Blackbaud CRM sync that turns new gifts into thank-yous on autopilot.
Custom Software DevelopmentMulti-Tenant SaaS Platform
We designed and built Ofyse, a multi-tenant SaaS platform that replaces the spreadsheet stack coworking operators rely on — unifying bookings, member CRM, recurring billing with regional tax, and multi-gateway payments behind one fast, modern workspace.
