It started at a kitchen table, with a few spare dollars.
SpareDollar isn't a startup. It's a homecoming: the seller tools Tomas first built for Kate's eBay listings in the year 2000, rebuilt by the same hands for 2026.
List once, sell everywhere, and never lose control. The technology changed. The mission didn't.
You might remember us.The name wasn't branding. It was the truth.
Kate started selling her things on pre-2000 eBay. Tomas was running network operations at a telco, writing little apps off-hours to make it easier for her to list and sell. She just wanted to make a few extra dollars. Spare dollars.
Twenty-five years later, she's selling again, from her iPhone this time. Different marketplaces, same hustle. She's still the user. She's still the reason.
Right now she takes the photos, uploads to eBay, then does it again on Depop, then again on Poshmark. One item at a time. Three times each. Same photos, same item, different app, over and over. That's the problem SpareDollar exists to solve. One photo. One listing. Every platform. Done.
Simple was the answer in 2000, before "UX" was even a job title. Simple is the reason now. The technology changed. The mission didn't.
Twenty-five years, one mission.
The kitchen table
Kate starts selling her things on pre-2000 eBay. Tomas, running network ops at a telco, writes little apps off-hours to make listing easier for her. The name came from the goal: make a few spare dollars.
eBay for Dummies
Marsha Collier features SpareDollar in eBay for Dummies. The first outside validation: the tools actually work for real sellers, not just the people who built them.
The platform expands
SpareDollar's tools merge into a dedicated seller platform serving tens of thousands of eBay and Amazon sellers. The technology scales. The mission stays the same.
Wix acquires the business
Wix buys the platform to add marketplace selling tools to its suite. The seller tools keep running. But a website builder and a reseller platform are very different products.
The platform shuts down
After twenty years, the platform closes with less than a month's notice. Tens of thousands of sellers are left without a home. The inbox fills fast.
SpareDollar comes home
NowThe same tools, rebuilt from scratch for where selling is going. Every marketplace. AI-written listing drafts. One listing, every platform. No revenue cut. The mission hasn't changed in twenty-five years.
Early by five to fifteen years: sold or shelved before the market caught up. That's not a failure story. It's the resume of someone who's been right about this market longer than almost anyone.
Every bet we placed for twenty-five years converges on 2026.
AI has collapsed the cost of listing friction to nearly zero. Marketplace fatigue is real. Sellers know they are sharecroppers on someone else's land.
This time, we're not selling early. SpareDollar started at a kitchen table and it ends up right back there: full circle, for the person who just wants a few spare dollars.
"Every tool here started as something we wanted for ourselves. Then we gave it to everyone else. That has been the only plan for twenty-five years."
The seller tools you remember.
Rebuilt for 2026.
