Artificial intelligence is no longer a distant promise for the public sector. It’s here, and it’s changing how services are designed, delivered and experienced. But as the conversation matures, so does the challenge. Public sector leaders are asking: how do we embed AI responsibly, at scale, and in ways that reflect the values of fairness, transparency and accountability?
At Capita, we believe the answer lies in infrastructure, not just innovation. That’s why we created the AI Catalyst Lab, our dedicated hub for identifying, testing and scaling AI solutions that deliver measurable business outcomes. The Lab is where ideas are explored and validated. But innovation alone isn’t enough – organisations need a way to embed those solutions into everyday operations.
That’s where the AI Catalyst Stack comes in. It’s the framework that works hand in hand with the Lab to turn proven concepts into practical delivery. The Stack is a modular system designed to help public service organisations deploy AI safely, effectively and with measurable impact.
This isn’t about technology for technology’s sake. It’s about enhancing productivity to free up frontline staff, improving outcomes for citizens, and making every decision more transparent. The Stack is already helping teams across government move from experimentation to execution, turning vision into delivery.
From promise to practice
In my previous CSW article, I explored the rise of agentic AI and its potential to reshape government operations. But potential alone isn’t enough. The real opportunity lies in embedding AI into the fabric of public service – without compromising control or trust.
The AI Catalyst Stack is built for this moment. It’s designed specifically for complex, regulated environments, such as central and local government, defence, health and education. It doesn’t require ripping out legacy systems or starting from scratch. Instead, it integrates, orchestrates and enhances what’s already there.
How it works
At its core, the Stack creates a “living digital twin” of your operations. It continuously monitors how things are working, spotting inefficiencies, compliance risks and opportunities to automate. Think of it as a real-time dashboard that sees everything and flags what needs attention.
It connects legacy systems, cloud platforms and AI tools using secure, event-driven APIs. It supports both low-code and pro-code environments, allowing teams to experiment safely while retaining full control. And it’s underpinned by a governed data layer that ensures information is handled securely and ethically.
But what makes the Stack truly different is its human-plus-agent partnership. AI agents handle routine tasks and coordinate workflows, while human experts oversee quality, compliance and empathy-led interactions. It’s not about replacing people – it’s about supporting them to do more of what matters – increasing productivity and improving citizen outcomes.
Designed for public good
Public service is built on values. The AI Catalyst Stack is designed with those values in mind. It’s not just technically robust – it’s ethically grounded.
We’ve embedded strong data governance, human oversight and sector-specific safeguards into every layer. Whether you’re a council leader, NHS manager or education director, you can trust that the Stack works with – not against – your responsibilities.
What’s next
The conversation around AI in the public sector is evolving. We’re moving from pilots to platforms, from isolated use cases to embedded capability. The real opportunity isn’t just to use AI – it’s to use it well.
Capita is proud to be helping public sector organisations make that leap. With the AI Catalyst Stack, we’re not just imagining the future of public service; we’re building it.
