Built for the loft, the cupboard, the box of mystery cables.

Most households sit on a few thousand pounds of perfectly sellable stuff. The PS4 in a drawer. The breadmaker that seemed like a good idea. Outgrown kids' clothes. Two pairs of skis from when someone briefly tried skiing.

We don't sell it because the listing flow is a punishment. Pick a marketplace. Take photos. Write a title. Write a description. Pick a category. Fill in twelve attribute fields. Set a price. Wait. Do it all again on Vinted because eBay didn't bite. Half an hour gone. Nobody bidding.

Haulder collapses thirty minutes into thirty seconds. Snap the thing. Haulder works out what it is, picks the category, writes a proper title and description, fills in every attribute, tidies the photos, and posts to eBay, Vinted, Depop, Gumtree and Facebook Marketplace at once. Sells on one, vanishes from the others. Your job is pressing one button.

Here's the trick. Every photo you took to sell something is also a photo of something you own. So while you're clearing out, Haulder is quietly building a catalogue of your house. Stick a sticker on a box. Scan it to see what's inside. Find the green crate even when you forgot it was green. Most inventory apps die after the first weekend because cataloguing your house by hand is a chore nobody finishes. Ours lives because you're already taking the photos. The catalogue happens whether you meant it to or not.

Small team. We use the app ourselves. We're building the version we wished existed the night we tried to sell a spare monitor and gave up at attribute field nineteen.
