Features

Your whole store in one platform
with nothing to stitch together

Products, stock, payments and AI agents run on one live record, so a change in one place shows up everywhere.

One catalog, every channel

Products, prices and stock live in one place. Change something once and every channel shows it.

Stock that never oversells

Inventory updates the moment an order lands, so you never sell what you don't have.

Payments, secured

Strict security practices by default, so you don't build them yourself.

Built for AI shopping agents

Agents search your live catalog, check out inside the conversation, and their orders land with every other order.

How it works

From import to first order
in one afternoon

Bring your products across, switch on your channels and take your first order the same day, without extra tools.

Import your catalog

Bring products across from a spreadsheet, a CSV or your old store.

Switch on channels

Pick where you sell, from storefront to marketplaces. Everything stays in sync.

Take your first order

Orders from every channel land in one list, ready to pack and ship.

Developers

One call to take an order
in the language you already use

Create products, take payments and stream orders with a few lines of code. Every SDK is open source.

Customers

Stores that sell everywhere
in their own words

Teams that moved from stitched-together tools to one catalog, and what changed for them.

“We used to update prices in four places and hope they matched. Now I change it once and it is live on the site, the app and every marketplace before my coffee cools. Launching a new channel went from a project to an afternoon.”

Marcus OkaforHead of Ecommerce · Fernwood Goods

+38%more orders across channels in the first month

“We opened on two marketplaces in a day. Same catalog, no spreadsheets, no copy and paste.”

Daniel ReyesFounder · Halden & Co

“We stopped overselling. Stock drops the moment an order lands, whichever channel it came from.”

Rohan NairOperations Lead · Loom & Lane

“The API did what the docs said. Our checkout was in test mode in a week and live the week after.”

FAQ

Questions, answered
before you ask

The things store owners ask us most before switching. Anything else, we are a message away.

Most stores are live in an afternoon. Import a CSV or connect your existing store, check the mapped fields, and switch on the channels you want. Your old store keeps running until you flip the switch.
