We are building Lion Market, DoorDash for collectibles.

Selling valuables directly to another person is hard.

When it comes to Pokémon, sellers have three options. The first is Facebook Marketplace, where people meet at police stations or in parking lots with cameras running, handing thousands of dollars back and forth in person. The second is selling to a local shop or vendor, which buys at 50 to 80% of market price. The third is an online marketplace, which means photographing, listing, answering messages, packing, and driving to the post office, with no visibility into what happens next and payment that lands much later.

What if selling were as easy as taking a photo? Finding the buyer, negotiating, pickup, and payment all happen for you, so your only step as a seller is that photo. And what if, when something goes wrong, someone held video of every moment in custody, so a dispute took minutes instead of weeks?

Lion Market is where that happens. AI negotiates the deal, finds when both sides are free, plans the route, and dispatches a driver to the door. The item is packed on camera and delivered, and every step is recorded, so disputes are settled by checking what happened.

When selling is this easy, everything in every closet becomes worth selling.

We are reimagining how buying and selling work in the AI era, where AI handles the complexity and robots will eventually handle the delivery.
