About
Trust, engineered from first principles.
A UK privacy-first technology company. We build software, advise on compliance, and publish evidence-driven research.
Company
A UK company, building in the open.
Incorporated in August 2025 in England and Wales (Company No. 16627148), headquartered at 20 Wenlock Road, London.
We operate at the intersection of privacy, compliance, and AI. Our portfolio includes Social Neuron, TheVPNMatrix, and Hearth, a local-first AI runtime currently in private development.
Values
Four principles that guide everything.
Privacy first
Privacy is an architectural constraint, not a feature you bolt on at the end. It shapes how data is stored, how it is processed, and what ships by default.
Evidence-driven
Every claim has a source. Every score has a record. The VPN evidence methodology cites 3,469 records and counting; the research articles cite the statutes they argue from.
Transparent
We publish methodologies and explain our reasoning in the open. Trust comes from showing the work, then letting the reader check it.
Independent
No affiliate revenue. No paid placements. Our products and research are not shaped by vendor relationships.
