Three roles, one triangle
Every role here covers product, engineering, and design. Each one is just anchored somewhere different, and the overlap in the middle is where the work ships.
How we work
We keep the team compact and the pace high. These are the habits behind it.
Ship fast
Weekly releases, not quarterly. Done beats perfect.
Own it
No task is beneath anyone. See a problem, fix it.
Think AI-first
Every feature should work with or without a screen.
Customer obsessed
Five-star reviews don't happen by accident. We earn them daily.
Sustainability matters
Growth only counts when it also cuts waste.
Small by design
Real impact, real ownership, real accountability for everyone.
We're building the future of sustainable commerce
SELLIT9 exists to keep usable items out of landfills while putting money back in people's pockets.
Every year the world generates more than 50 million tonnes of e-waste. Most of it starts as something fixable sitting in a drawer, because selling is inconvenient, offers are too low, and the process feels hard to trust.
We're changing that.
- $3.0M+Completed trades
- 4,800+Trusted customers
- 337,500 kg+CO₂ avoided
The people behind every trade-in.
A small, focused crew building the software layer that turns used tech into instant value for sellers, merchants, and brands across North America.
