Honest comparison vs. Gavelry.

Gavelry is the most-similar competitor at this scale. Their pricing is flat-rate; ours is sandwich-style with per-auction usage. The math:

Auctions per monthHammerwerksGavelry Starter (≤200 lots)Gavelry Pro (unlimited)
1$148$149$349
2$197$149$349
4$295n/a (>200 lots)$349
6$393n/a$349
12$687n/a$349

Where we win: AI lot drafting (Gavelry has none), per-tenant data isolation, 24 white-label themes, founder access. Where Gavelry wins: cheaper at very low volume (1–2 auctions/mo), flat-rate predictability at very high volume (6+/mo). At 3–5 auctions/month with multi-vertical catalogs, we're meaningfully cheaper.
