About
Most things don't go unsold because they're worthless.
They go unsold because deciding is exhausting. Which app? What price? Is the scratch a problem? What do I even write? Four small uncertainties are enough to keep a perfectly good chair in a spare room for three years.
Why I built GoSell
Selling something you already own is harder than it should be.
You look at an item and immediately face a string of decisions: What is this actually worth? Where should I sell it? Is it worth shipping? How should I photograph it? What should I say in the listing? Am I pricing it too high—or practically giving it away?
I've spent much of my career in product and technology, including work with Walmart, Nike, and Gap, building products and experiences that take complicated information and turn it into something people can actually use. But my background also includes theatre directing and design, learning and instructional design, and a lifelong instinct for looking at something and thinking, How could this be presented better? How could this be easier?
Those worlds came together in GoSell.
I wanted to create something that could look at an item alongside you and help answer the questions that come before the sale—what it's worth, where it belongs, how to present it, and what to do next.
You shouldn't have to become a resale expert just to sell the things you no longer need.
GoSell gives you confidence before you sell.

Principles
How we decide what to build.
Reduce uncertainty
Every screen should leave you more sure than it found you. If a feature adds doubt, it doesn't ship.
One clear decision at a time
No screen asks you two things. Confirm the item, then value it, then pick a marketplace, then write it.
AI explains itself
A recommendation without a reason is just an instruction. We show the comps query, the fees and the ranking logic.
Simple beats clever
A range you understand is worth more than a model output you don't.
The team
The people behind GoSell.
