Capstone has grown beyond accountancy. Today we build specialist software across financial services, wellbeing & performance, and business operations — each division engineered by domain experts who live the work every day.
The tools UK accountancy runs on. Client management, HMRC deadlines, automated emails, time tracking, and billing — engineered with practising-accountant insight.
The Forge is our AI-powered training operating system — adaptive programmes, real-time coaching, and precision analytics for HYROX, CrossFit, and serious athletes.
Internal tools, workflows, and systems that help businesses run smarter — built by operators who've scaled companies and know where the friction lives.
We don't build generic software and hope it fits. Each Capstone division is shaped by professionals who've lived the challenges our products solve.
MTD ITSA, CIS, VAT, and Companies House workflows designed by people who've filed the returns, chased the clients, and run the practices.
Training science, periodisation, and recovery built into every programme — engineered by competitors who understand what it takes to perform at the highest level.
Operational workflows, team systems, and automation designed by people who've built and run real businesses — not generic SaaS bolted on after the fact.
