About Closo
The operating system for resale sellers.
Closo runs your whole business in one place: list across marketplaces, price and sell with AI, source inventory, and keep the books straight. Resale becomes a real business — not a scramble across a dozen tabs.
Our mission
Turn resale side-hustles and full-time stores into real businesses — with tools once reserved for the big operators.
Why we exist
Reselling grew up. Sellers list on six marketplaces at once, negotiate offers all day, source inventory in bulk, and file taxes at year-end. The tooling never caught up. Closo is the operating system we wished existed — it handles the busywork so you can focus on finding great inventory and moving it.
What we build
One platform for the whole resale business.
Each piece works on its own. Together, they run the whole operation.
AI agents
Price signals, demand insights, and agents that handle offers and sharing for you. They watch every marketplace and act on it — so your listings stay competitive without the manual grind.
Wholesale
Source inventory in bulk and sell dead stock as lots. Bundle slow-movers, set price floors, and reach buyers — a marketplace built for how resellers move volume.
Expenses & Taxes
Sales, fees, and costs from every marketplace in one place, so the numbers add up at filing time. Know your real margin per item — not a guess.
Financing
Working capital built on your real sales history. Buy more inventory when the deal is right, not just when cash is on hand. Funded by a licensed partner — money in your bank in days, no credit-score gate.
Built on your session
The browser extension does the marketplace work through your own logged-in session. Closo never stores your marketplace passwords — by design, not by accident.
The AI agents
Help where the work actually is.
Agents unlock by plan. Free includes 0 AI actions a day, Pro includes 30, and Unlimited is uncapped.
On Pro
30 AI actions / day- Listing Booster — sharpen titles, photos, and details so listings surface and sell.
- Auto-Sourcing Agent — move slow inventory with guided, data-backed nudges.
On Unlimited
∞ AI actions / day- Auto-Pricer — keep prices competitive automatically as the market shifts.
- Auto-Offers — send and answer offers on your behalf, within your rules.
- Auto-Share — keep listings in front of buyers, no manual tapping.
Sourcing Autopilot — spot sourcing deals worth acting on. It's pre-paid: it runs on a budget you approve and fund up front, so it can source for you on any plan.

How we build
Principles behind the product.
01
Sellers first
Every feature earns its place by making a seller's day easier or their business more profitable. If it doesn't, we don't ship it.
02
Your accounts, your control
Closo works through your existing browser session. We never store your marketplace passwords — your accounts stay yours.
03
One place, less busywork
Listing, pricing, sourcing, and bookkeeping shouldn't live in a dozen tabs. We bring them together so your work compounds instead of scattering.
