Proxibid brings reach, and it’s real — especially on equipment, vehicles, and heavy iron. We’re not going to pretend we match it. But the bidders you spent years earning register to the marketplace, not to you — and the catalog and the books are still yours to sweat at midnight. Hammerwerks is that layer underneath: it drafts the lots, keeps the list in your name, and settles the sale. Plenty of folks run both.
The honest framing first, because it saves everyone time. Proxibid is where a lot of bidders come from. Hammerwerks is how the catalog gets built, reviewed, and settled — and how the list stays yours. This is rarely an either/or.
A pool of registered bidders and a storefront to list into. That reach is real, and on some verticals it’s the whole point. We’re not here to talk you out of it.
You shoot phone photos of each lot — or text a helper a no-login capture link — and the AI drafts the title, description, category, condition, and a value range, each with a confidence score. A second AI reviews it. You approve every one, and the list stays in your name.
Catalog through us, list to a marketplace for the audience, then settle here when the last lot hammers. Adding us is a published monthly line you can plan around — not another cut of your gross.
Capability by capability. Where we can’t verify a Proxibid detail from public information, we say so rather than guess — this is as of 2026, based on what they publicly document.
| Capability | Proxibid | Hammerwerks |
|---|---|---|
| Registered-bidder reach / marketplace audience | Large and established, as of 2026 — a genuine strength | We don’t have it, and won’t claim to |
| Reach for industrial, heavy equipment, vehicles | Particularly strong in these verticals, as of 2026 | Not our strength — list to a marketplace for it |
| AI drafts each lot from photos, with a confidence score | We haven’t found a comparable feature | Core — AI drafts, a second AI reviews, you approve every lot |
| Says “I don’t know” on coins, jewelry, art, thin markets | We haven’t found this | Flags its uncertainty instead of inventing a number |
| No-login capture link for a helper | We haven’t found this | Scoped, revocable link — text it to a helper, no account |
| Recall check (NHTSA/CPSC) + identifier lookups (VIN/ISBN/marks/UPC) | We haven’t found this | Run automatically as the lot is drafted |
| You own your bidder list | Bidders register to the marketplace’s pool, as of 2026 | Your list stays yours — export it any time |
| Branded bidder site on your own domain | Marketplace-branded storefront, as of 2026 | White-label on your domain |
| Settle against a signed consignment contract + reconciled books | We haven’t found this | Settle to a tamper-evident agreement; trust balance and 1099 worksheet reconcile |
| Run the back office by talking to ChatGPT | We haven’t found this | MCP server — operate the workflow from ChatGPT |
| Published pricing | Generally a percentage of the gross plus fees, as of 2026 — confirm current terms with them | Tiers at $99 / $299 / $799 a month. No cut of the hammer, ever. |
Not on reach — on the part that’s yours to carry no matter where the bidders come from: the list, the cataloging nobody does for you, and the settlement math.
You can spend twenty years earning a buyer’s trust and still watch that name quietly become the marketplace’s asset, with a slice coming off every hammer besides. Here the list stays in your name and exports any time, your catalog runs white-label on your own domain, and we never take a percentage of what the gavel brings.
You know the Sunday-night scramble — one person typing lot after lot so the sale can open Monday, and the quiet fear that some tool will invent a price and burn your credibility. Photos in, drafted lots out, each with a confidence score, a second AI reviewing, you approving every one. On coins, jewelry, and art it says “I don’t know” instead of faking a grade.
Settlement math shouldn’t eat your evening, and a consignor shouldn’t be able to dispute the commission six weeks later. Settle against the agreement they e-signed and you countersigned — fingerprinted and provable — at each seller’s rate. A lot won’t pay out before its buyer money lands, and the trust balance, 1099 worksheet, and sales-tax report reconcile as you go.
No, and we’d usually tell you not to. Proxibid brings the audience; we build and settle the catalog and keep the list yours. Most operators run both — catalog through us, list to the marketplace for reach.
Not many, and we won’t claim otherwise. Our pool is small; a marketplace like Proxibid has the reach, as of 2026, and that’s a real reason to keep it. Where we earn our keep is the workflow — cataloging, owning your list, squaring the books — not raw audience.
Partly. For buyer reach on heavy verticals, a marketplace like Proxibid is genuinely strong and you’ll likely want to keep it. Where we help is cataloging speed, recall and identifier checks, and getting the books settled — and you can do both.
It drafts each lot with a confidence score and a second AI reviews it, but you approve every one. It saves the typing, not the deciding. On items where authenticity or grade matters — coins, jewelry, art — it says it’s unsure instead of inventing a number, so you can open at a set bid rather than publish a fantasy estimate.
Ours is published and tiered: Solo is $99/mo for 200 lots, Growth is $299/mo for 1,000 lots and 500 AI credits, Scale is $799/mo for 5,000 lots and 3,000 AI credits.

There’s a one-time $499 setup, waived with a promo code, and a 30-day money-back guarantee. No cut of the hammer, ever. Marketplace pricing is generally a percentage of the gross — check their current terms directly, since we won’t quote numbers we can’t verify.
Yes. Start at app.hammerwerks.com/signup, or book a call and we’ll walk your actual workflow. The 30-day money-back guarantee and full data export mean you can run a real sale through it and walk away with your data if it’s not for you.
