Samsby
Business software that does the heavy lifting. Sam answers the phone; every job stays in one place.





Made for the bench
Samsby is for trades run from a phone between jobs. It grew inside a carpentry business in Perth, so every screen meets a real job before it meets anyone else.
Velochat
The social app for cyclists. Every ride gets its own chat, every club its own home.




LiftGauge
An honest training log for lifters. Log a set in seconds, then watch the graph climb.
Try it: log a set of squats
Volume so far: 0 kg

About Ruitan
I'm Ruitan Huang, a product and systems designer. I design whole systems, and the AI that works inside them, then build and ship them.
Samsby is the largest: one system for a trade business, from Sam, the AI receptionist that answers the phone, to enquiries, jobs, quotes, invoices and follow-ups that AI drafts and the owner sends. Velochat and LiftGauge bring real-time chat, sync and offline use to riders and lifters. The longer story is on its own page.
