About the company

PM Technologies runs an online marketplace for rare coins and precious metals where buyers, sellers, and dealers trade through a bid/ask system similar to a stock exchange. Items are authenticated at a Los Angeles processing facility using XRF technology and proprietary software before being sent to buyers, with buyers able to buy at the lowest ask or sellers to sell at the best bid, or place bids/asks for future matching. It differentiates itself with transparent price discovery, formal authentication, and a platform that serves collectors, stackers, coin shops, and online dealers, supported by Y Combinator participation and seed investors. Its goal is to reduce fragmentation and opacity in the collectibles and precious metals markets by enabling a trustworthy, data-backed, peer-to-peer marketplace for physical assets.

Simplify's Take

What believers are saying

  • Pure claimed over $45 million monthly transactions on LinkedIn in August 2026.
  • Vault Shipping beta in August 2026 reduces buyer friction and expands repeat purchasing.
  • Y Combinator support and seed backing from Pioneer Fund and Ludlow Ventures validate the thesis.

What critics are saying

  • Heritage Auctions and APMEX already dominate liquidity, brand trust, and speed.
  • Pure has only 1-10 employees, making ops failures and fraud hard to absorb.
  • If buyer volume stalls, verification costs and shipping complexity can kill unit economics.

What makes PM Technologies unique

  • Pure runs a live order book, not dealer spreads, for coins and metals.
  • Pure authenticates every item at its Los Angeles facility before buyer shipment.
  • Pure pairs trading with a 7-million-record pricing index across 72,000 coin varieties.

Introducing the Vault Shipping Feature (Beta)

Introducing the Vault shipping feature (beta). On February 25, 2026 Introducing the Vault feature (now live for beta users). Collectpure is excited to roll out its new Vault System, a secure way for users to store their precious metals directly with Collectpure instead of shipping them out right away. This feature was built for collectors and investors who want an easier way to manage their metals without worrying about storage, shipping, or handling every time they make a move. What is the Vault System? The Vault System lets you keep gold safely stored in its secure facility while still maintaining full ownership and control. Once your metals are vaulted, you can manage them right from your account - whether that means listing them for sale, transferring them to another user, or requesting delivery whenever you choose. Collectpure plan on allowing other metals to be stored in its vaulting system when the vault feature is fully built out. How it works. When a vaulted item arrives, it's received, verified, and securely stored on your behalf. From there, you can view and manage your vaulted metals directly in your dashboard. No extra steps, no need to handle the product yourself, and no need to arrange storage elsewhere. Why it's in beta. The Vault System is currently available to a limited group of beta users while Collectpure continue testing and improving the experience. This phase helps Collectpure make sure everything runs smoothly and gives Collectpure the chance to gather feedback before expanding access to more users. Built for what's next. This is an important step toward making metal ownership more modern and flexible. Over time, Collectpure'll continue adding features and improvements that give you more control over how you store, manage, and move your metals on the platform. Get started. If you're part of the beta group, you can start using the Vault System today from your account dashboard. Collectpure'd love to hear what you think as Collectpure continue shaping the feature ahead of a full release.
