The strategy
We refused to sell everything.
Sotheby's, Christie's and Artsy chase all of fine art — from antiquities to NFTs. That breadth spreads expertise thin and leaves whole categories under-served.
Vault owns a single, authenticatable vertical: Post-War & Contemporary painting. One category, mastered — deeper provenance, sharper estimates, and specialists who know every hand on the canvas.
Browse the current saleDepth over breadth
Every specialist, comparable, and valuation model is tuned to one market — so nothing gets a generalist's guess.
Authenticatable
Catalogue raisonné coverage and documented ownership make this the niche where trust can actually be proven.
Under-served
Mid-market masterworks the majors overlook — the $4k–$14k lots where collectors build real positions.
AI-native
Built around intelligent agents from day one — not a century-old process with software bolted on.
The platform
Everything a serious bidder expects.
We rebuilt the auction stack around trust and speed — the two things the legacy houses make hardest.
Real-time bidding
Live and timed sales sync across every device in milliseconds, with anti-sniping extensions and max-bid automation so a fair fight stays fair.
Transparent provenance
Chain of ownership, exhibition history, and condition reports are published on every lot page. No black boxes, no whisper estimates.
Integrated settlement
Escrow-backed payment, insured logistics, and instant invoicing built in. Win a lot at midnight, settle before you close the tab.
Verified authentication
Catalogue raisonné checks and specialist sign-off on every consignment. Works that fail verification never reach the block.
Members-only access
A vetted room of serious collectors and investors. Private previews and priority on marquee consignments before each public sale.

Collector voices
Built for people who buy seriously.
“The valuation agent answered a provenance question at 2am that my usual house took three days to return. I bought the lot with confidence.”
Eleanor Vance
Private collector, Geneva
“Finally a house that picked a lane. Their depth in post-war painting is the reason two of my consignments beat their high estimate.”
Marcus Thorne
Art advisor, New York
“Transparent fees, escrow settlement, real-time bidding that actually works on mobile. Vault feels built this decade, not the last century.”
Priya Nair
Collection director, Singapore

Questions
Everything you were about to ask.
Focus is our advantage. By owning a single, authenticatable vertical instead of chasing all of fine art, our specialists, provenance research, and AI valuation models go deep rather than wide. Sellers get sharper estimates; buyers get genuine expertise on every lot.
Our valuation agent benchmarks a work against comparable results, edition data, exhibition history, and current demand signals, then hands a structured brief to a human specialist who signs off. It answers collector questions instantly, day or night — but a person always confirms the final estimate.
Every lot passes a documented chain-of-ownership review, condition report, and catalogue raisonné check before it reaches the block. Provenance is displayed transparently on each lot page, and consignments failing verification never list.
Buyers pay an 18% buyer's premium on the hammer price. Sellers pay a 10% commission on completed lots. No listing fees, no hidden charges — the full schedule is shown before you bid or consign.
Timed and live sales update instantly across every device with anti-sniping extensions, so a bid in the final seconds fairly extends the clock. You can set maximum bids and receive alerts the moment you're outpaced.
