Official opportunity
We retain the official notice, buyer, deadline and visible requirements.
Know before you bid.
Find the opportunity. Check the evidence. Decide clearly.
Citrine helps UK suppliers identify relevant public procurement opportunities, assess fit from public evidence and see what still needs confirming before they invest bid time.
A trust-first screen
Useful evidence without pretending unknowns are answers.
Supplier evidence
We compare the opportunity with specific facts from supplier-owned pages and public corporate records.
Controlled next step
We identify the questions that still need a supplier or tender-pack answer. You decide whether to proceed.
Citrine Opportunity Evidence Map
Public evidence, clearly scoped.
We provide source-linked opportunity screens and evidence maps. Written scope confirmation comes before any paid work.
