The AI-Powered Solution Development Company
Provanta is an AI-powered solution development company based in West Berkshire, helping SMEs across the UK build better business systems faster and more cost-effectively. We combine over 40 years of hands-on experience in complex business systems with AI-driven development through ORCA, our proprietary AI-led development engine. We specialise in bespoke solution development, legacy system modernisation, AI integration and agents, rapid solution prototyping, MCP server development, business solution consultancy, and ongoing maintenance and support. Our sector experience spans insurance, finance, ecommerce, healthcare and property. What sets us apart is our prototype-led approach. Rather than months of requirements gathering before you see anything, we deliver fully functioning prototypes in hours — letting you validate the direction, engage stakeholders, and reduce project risk from day one. The result: solutions delivered up to 90% sooner at up to 75% less cost than traditional development. We put human expertise first. AI generates the code, but experienced solution architects design the architecture, understand your business requirements, and ensure the solution genuinely fits how your organisation works. This combination of deep technical experience and modern AI tooling means you get the quality of a senior development team at a fraction of the usual cost and timeline. Our clients trust us with their critical systems — some partnerships spanning over 15 years. We are built on long-term relationships, honest advice, and doing the right thing for your business.
