Hammerworth is the operating system for auction houses and appraisers — intake, AI-assisted appraisals, catalog handoff, and a CRM that turns relationships into hammer prices. One platform, from inquiry to settlement.
From old masters to estate silver — software that respects the work.




Stop stitching together email, spreadsheets, paper contracts, and sticky notes. Hammerworth runs the entire consignment lifecycle in one place.
A mobile-friendly consignor form and a single triage queue. Category-specific fields, photo checklists, and tracked requests for what’s missing keep every inquiry moving.
Draft appraisal research, object context, comparable records, and a value range in one workspace. Your qualified staff reviews every conclusion before placing the finished PDF in the client vault.
Match incoming lots to collectors based on purchase history, then prepare focused campaign drafts for staff review and handoff to your existing marketing workflow.
Estimates, reserves, condition notes, and photography checklists flow into a clean, export-ready record — built to hand off to Bidsquare and the platforms you already sell on.
The same flow your team already follows, with one record from intake through settlement and a clear review point before client-facing work leaves the house.
Consignors and appraisal clients submit item details and provenance through one branded form, with photo follow-up handled by staff.
AI researches comparables and drafts values. Staff accept, decline, or generate a paid appraisal.
Staff reviews collector matches and campaign drafts, then prepares catalog records for export.
Records hand off as Bidsquare-ready CSV files; imported results update consignor history and settlement records.
Start with intake and appraisals; add the full collector CRM as you grow. No per-lot fees.
Start a trial, make the workspace yours, import your history, and bring the team in. Complex data or integration needs begin with a scoped onboarding plan.
Two fields and a card — Stripe holds it, and day 15 is the first charge. Cancel before then and pay nothing.
Apply your logo, colors, and house identity across client-facing intake and portal views.
Past sale CSVs become private comparables, a buyer list, and an unsold pool ready to re-offer.
The owner invites staff and appraisers; clients get a passwordless portal — nothing for them to manage.
