About

A UK software studio, built deliberately small.

Vantara Labs Ltd is a UK-registered software studio. We build small, focused web apps. Some of them turn public datasets into readable dashboards, starting with Pelosi Tracker . Others help you keep track of your own thinking, such as Leyden .

Story

Why this exists

A lot of valuable public data is stuck behind bad interfaces. Regulatory filings live in PDF. Government disclosures live in Excel. Parliamentary registers live in semi-structured HTML. Reading any of it well is a job, not a browsing experience.

A lot of valuable private thinking is stuck behind bad interfaces too. The half-formed idea you had on a walk, the connection between two thoughts you had three months apart, the note you cannot find when you actually need it. These are workflow problems that modern AI is genuinely good at solving, provided somebody builds a calm, focused tool.

Vantara Labs builds small, focused web apps that tackle both kinds of problem. Each product does one job well, with the option to dig deeper if the reader wants to.

The studio exists to let each product stay small without having to re-invent infrastructure, design, or legal every time. Shared tooling lives here; each product lives on its own domain with its own focus.
