About the Company

PM Technologies

Online bid/ask marketplace for rare coins

PM Technologies runs an online marketplace for rare coins and precious metals where buyers, sellers, and dealers trade through a bid/ask system like a stock exchange. Items are verified at a Los Angeles processing facility using XRF technology and proprietary scanning software before being shipped to buyers, and users can either accept the best bid/lowest ask for immediate trades or place bids/asks to wait for a match. The platform emphasizes price transparency and authentication, supports a large database of historical pricing records, and serves collectors, stackers, coin shops, and online dealers, with YC-backed seed funding. The goal is to reduce fragmentation and opacity in the collectibles and precious metals market by offering a trustworthy, data-backed peer-to-peer marketplace for physical assets.
