Justin Jarvinen is a world-class innovator, business designer and 0→1 operator.
Line shopping is six apps and a math quiz — and the number moves while you're doing it.
One board that watches every book and lights the best price. Tap it and the slip loads in your book, number and all. It's live.
Your AI writes a fine deck. Ask it to design one and it's a crap shoot — system fonts, committee color, charts from 2009.
A shelf of premium, AI-ready design: palettes, type systems, chart motion, master prompts. A few dollars a piece, cheaper bundled — build a System and drop it into your agent.
Production gear travels as a pile — cases, carts, someone's trunk. The pile doesn't fit through a doorway.
The Tyo Worksystem™ — rugged, modular, serialized, engineered as one system, down to the wheels. It rolls through a doorway and sets up where it stops.
The signals are public — filings, job posts, ad copy, options flow. Reading them all is a desk job nobody staffs.
One screen that reads the tape and hands you the play — the alpha, the edge, the window. Building it now.
Youth hockey runs on a coach's memory. The numbers that make a player die in a spreadsheet nobody opens.
A broadcast-grade player desk for an academy — every shot, shift, and sprint scored, so development is a number you can watch move.
The plan dies in the group chat. Nobody books, everybody's "in," and one guy fronts four grand.
You pick the weekend. GROOMS handles the part you hate — the plan, the table, the rooms, the money. Nobody gets chased. Everybody shows up.
A small deposit locks everyone in. The headcount holds. You stop chasing anyone the week before.
The card's already loaded. The money just arrives. Chased on Venmo? The fund asks for you.
She books the table you couldn't get, and answers before you've set the phone down.
When you're serious — an idea, a patent, a mess — I'm easy to find.
