How the Platform Works

Users create listings by pasting a product link into the app, which uses artificial intelligence to automatically pull item details. Other users can then “call” the item, offering to rent or buy it at a specific price and date. The platform aims to reverse the traditional resale model by identifying future demand for a product before the initial purchase is made.

Business Model and Beta Results

During beta testing, fewer than 300 users listed over 500 items, with 70 percent of “calls” focused on rentals and 30 percent on purchases. The business model charges service fees and protection fees for both buyers and renters, while listers pay no commission on resale items and a 15 percent commission on rentals. Trace recently raised $3 million in a seed funding round led by Serena Ventures, with participation from Shakti VC.

Launch Events

To mark the app's launch, Trace is hosting a pop-up event at the Shopify SoHo location from Friday through Sunday. The event features shoppable edits from eight stylists and includes trunk shows from various women-founded brands, alongside scheduled programming.
