01 / Products

Two products, built and run in-house.

Each product runs on its own domain with its own focus. They are our products, not client work.

Pelosi Tracker

Live

Track US congressional stock trades, with context.

A subscription app for the web and iPhone: every STOCK Act disclosure from the House and Senate, normalised and rendered as a dashboard instead of a PDF. Email alerts and historical analytics, plus real-time alerts and CSV export on Pro, for the people who actually read the filings.

Leyden

On hold

AI-powered idea capture: speak or type, and it files itself.

Turn fleeting thoughts into structured, connected ideas. Speak or type a raw note; AI titles and tags it, asks follow-up questions when an idea is half-formed, and links related ideas. The core web app was built in early 2026; the project is on hold and not publicly available.

02 / How we work

Small, focused, and built to last.

One job per product: Each product we run earns its keep by doing one thing well, whether that is turning a public dataset into something readable or helping you keep track of your own thinking.
Boring infrastructure: Static-first hosting, deterministic builds, and Infrastructure as Code. Every hour we save on maintenance goes straight into product features you can see.
Clear by default: Plain English, sensible defaults, and answers on the first screen. The dashboard should make sense before you reach for the docs.
