Clutch runs a working brick-selling business every single day. Everything in it exists because a real order, a real shortage, or a real price drift demanded it.
Clutch started as an internal tool: one seller, thousands of lots, two marketplaces, and a spreadsheet problem that was getting worse every month. The sync engine came first. Then the conflict queue — because silent overwrites cost money. Then the order pipeline, the pricing rules, the BrickStore import.
By the time it became a product, every feature had survived real orders. That is still how it develops: features ship when sellers need them, and the app is updated constantly based on what users actually say.
