Lyon Empire: a one-person product house in London

I build and operate my own products. Lyon Empire is a one-person product house in London; everything below is something I made and still run. None of it is client work.

The register

two ventures, one co-founded studio

01

Prasso

A directory of yoga, pilates, reformer and wellness studios across the UK, wrapped around a private record of the classes you actually take.

live, unannounced
no testers invited yet
Nuxt, TypeScript, Postgres

02

Bubba

A cast object with an NFC chip in it, and an iOS app that locks your distracting apps until you get up and tap it. The app keeps a ledger of every break you take, narrated by a bored devil who records it without comment.

live, early access
in testing
React Native, Screen Time

Also: The Reset Rooms, a pilates and wellness studio in Crouch End that I co-founded and that trades today. It is a separate venture, not a Lyon Empire product.

Smaller: two Chrome extensions, both published on the store. Vinted Favs filters and sorts Vinted favourites; Cart Tools for Shopify logs, copies and edits carts and products, and pulls SKUs, for testing themes. Neither is the business, but both are mine and both are in use.

Leave evidence.
Digital work sanitises humanity.

Conviction.
Say who it is not for.

Stick the landing.
If it needs explained, it doesn't work.
