I make your work my world.

Jacob Irontree. Fifteen years hands-on working with the people who design software, the people who build it, and the people that run their businesses with it. I do all three. This fall I rebuilt a decade of my designs as working software in a few days, mostly for the love of the game. They're running on this page.

2026 to now

$35.7B in tickets sold through Ticketmaster in 2023, on a platform whose pricing I designed. 89% fewer support tickets for 75 million grocery shoppers. A law firm's traffic 8x the month after a rebuild I designed and coded myself.

One person who does it all

Most teams need a designer, an engineer and someone who knows how the business runs. I do all three.

01 Design
I learn your domain until I can argue with your experts.

Pricing floors, pharmacy counters, grocery carts, a courtroom's worth of case law. I sit with the people doing the work, then design like the product is mine. If it doesn't feel right, it doesn't ship.

02 Engineering
I build what I design, so the first review is running code.

Fifteen years of front end, from a lead developer role to shipping production sites and apps. Your engineers get a spec written by someone who has had to implement it with real users, and prove how designs would actually profit.

03 Business
One number, agreed up front, decides what ships.

I've asked executives to shelve my own project because the research said otherwise so we can build the right thing, first. That's how a pricing tool became the profit engine behind ticketmaster.com.

About

Brown computer science, RISD design. I studied computer science and emerging technologies at Brown, then became one of the first undergraduates admitted to RISD's Digital Media graduate program. I started my career in design & engineering, moved into UX, and have spent the last decade leading design on software that prices, sells, and supports billions in revenue and profit. I know it end to end because I finish what I start, and I am way too ambitious for my own good.
