About
Evidor is a product. Nexusdesk is the company. Both live in Singapore.
Evidor.ai is the AI compliance plane built by Nexusdesk Pte Ltd, a Singapore-incorporated deep-tech company. We build infrastructure for regulated firms that need to use AI without losing track of what their AI did with their data. Founded in 2025. Backed by Enterprise Singapore. Patent-pending.
Origin
Compliance specialists who got tired of writing policy memos that nobody could enforce.
Anson Zeall founded Nexusdesk after a decade in compliance and regulatory technology, where the same problem kept appearing: policies are written, audits are passed, then a tool with no audit trail walks into the firm and breaks the chain. AI is the latest version of that problem at industrial scale.
The team gathered the technical foundation to actually fix it: classification, redaction, hash-chained audit, model routing. Evidor is what got built. The patent (US provisional 63/885,250) covers the core architecture.
We are pre-revenue and selective. The first three customers will be discovery partners we learn from. The product they help shape is the one we ship to the next thirty.
