One verified, structured view of the UK and Ireland public sector market. Every figure linked back to its source.

Who's buying, who's selling, and what they're spending — across 300,000+ companies and 1,000+ public sector buyers in the UK and Ireland.
Arcamus aggregates and structures data from Contracts Finder, Find a Tender, Companies House, public sector buyer websites, and supplier filings — turning fragmented sources into one verified, queryable view. Every record links back to its original source, so you can see exactly where every insight came from.
The result: a clear, filterable view of the public sector market that helps teams identify trends, size opportunities, prioritise the right accounts, and make faster, more confident decisions.
A public sector contract is permission to spend, not a guarantee that money flows. Arcamus tracks the actual invoice payments from each public body — so you can map real revenue and market share, not just announced contract values. Validate targets earlier, stress-test theses faster, and bring the rigour of a £200k due diligence process forward to origination.
Strategy meetings shouldn't run on anecdote. Arcamus gives you a structured view of where public sector spend is growing, where competitors are concentrated, and where the whitespace is — across regions, sectors, and frameworks. Build three-year plans on what's actually happening in the market, not what was true two years ago.
Most of the accounts your team is chasing aren't ready to buy. Arcamus shows you which buyers are actually spending, which competitors are already in the room, and which sectors are worth the focus. Qualify in minutes, prioritise by real signal, and win more of the bids you choose to chase.
Walking into a bid blind is one of the most expensive things your team does. You walk in knowing the incumbent, the contract value, the renewal date, and the competitor track record before you commit a single hour of pre-sales effort. Track frameworks and renewals early — so the opportunities that matter are on your radar long before the tender drops.
Arcamus is powered by AI, but grounded in real public records. Every insight links back to its source — so you can always see where it came from.

Every data point in Arcamus opens to the underlying record — the contract, the filing, the tender notice. So you're never trusting the model. You're checking its work.

We use AI for what AI's good at — research, summarisation, finding patterns across thousands of documents. The data and citations stay untouched.

Every answer comes with its working — sources cited, data points linked. Take it to the board. Take it to the IC. Take it to procurement.
The data layer underneath Arcamus deepens every week — new buyers, new contracts, new spend records, new connections between them. Customers who sign up today get every improvement that comes after. The longer you're with us, the sharper the picture.
