Cat DB is a marketplace built to make selling catalytic converters fast, easy, and reliable.
Instead of guessing, calling, posting, or driving around for quotes, the app instantly shows you top catalytic converter prices based on how you’re selling — and connects you with buyers nationwide who offer app displayed prices or above.
Everything is aligned upfront, so selling is simple, smooth, and seamless.

Cat DB uses a unique pricing system to show you high catalytic converter offers based on how you’re selling.
Instead of displaying raw market indicator numbers that require long negotiations, Cat DB uses your seller profile to surface top live offers from marketplace buyers. Then we connect you with buyers who work with sellers like you and can pay app displayed prices or above.
The process is simple:
You answer a few quick questions about how you plan to sell
Cat DB shows a top offer available now for your seller profile using current marketplace buyer offers
You add cats to your cart and tap “view all buyers” to see a list of buyers who can pay that price (or higher), and contact the buyer you want to work with
You’ll be asked a few questions that help match you to the best offer and the right buyers, such as:
How many catalytic converters you sell at a time
Whether you’re a business or an individual
If you’ll be using the app to sell vs. buy and resell
These answers matter because buyer pricing often depends on quantity minimums and compliance requirements.
The price shown is a top offer currently available for your seller profile — based on the details you provided.
You’ll also see which marketplace buyers can pay this advertised price or above that offer by tapping “view all buyers” in your cart. Buyers may offer more depending on market conditions, seller loyalty, and the logistics of the sale.
Buyer offers can update up to 3 times daily as they follow the PGM market. Offers also depend on seller qualification (including required compliance paperwork & logistics). The choice to purchase and final price is ultimately determined by the buyer.
Cat DB doesn’t just show prices — it matches seller level to buyer capability.
That means:
Smaller sellers are matched with buyers who accept smaller quantities, have low or no minimums, and are set up for piece-based sales
Larger sellers are matched with buyers who require higher minimums and are equipped for volume shipping, logistics, and even assay-based transactions
This helps avoid wasted time contacting buyers who aren’t a fit for your quantity, terms, or licensing.
No. You can price here, and sell anywhere.
Cat DB shows you a list of marketplace buyers who fit your selling method and can pay at or above the offer shown — you can sell to them or use Cat DB offers as a reference point when comparing prices from buyers outside the marketplace.
Note: Purchase approval and final pricing are determined by the selected buyer and may depend on compliance requirements and item details.
Traditional cat selling has meant calling multiple buyers, posting online, driving around, even meeting multiple buyers, and still ending up with low or unreliable offers.
Cat DB makes it easier because it:
Shows top catalytic converter offers based on your real selling qualifications
Filters buyers by fit (quantity minimums, shipping/transit, piece vs assay, compliance)
Reduces back-and-forth and wasted calls
Connects you with a wide selection of cat buyers nationally
The result is quicker, smoother transactions for both sellers and buyers.
Yes. The system is designed to scale — whether you’re selling a single catalytic converter or shipping large volumes.
By adjusting both offer visibility and buyer matching, Cat DB supports sellers at every level.
You can update your pricing settings anytime by going to Settings → Prices, then retaking the questionnaire or selecting the pricing view that best fits.
If your quantity changes or you switch from piece-based sales to assay, the offers and buyer matches will update accordingly.
Live Market refined prices are available upon request for qualified recyclers. We also offer an Enterprise Plan for custom assay pricing based on your hedge, return rate, fees, and interest margin.
