Fine Art Market Intelligence and Subscription Platform
A dedicated WeyBee team builds and modernises a global art-market data platform: 4M+ users, 300,000+ personalised alerts a day, 54+ microservices, a new dealer product and an AI market-insights chat.
AIPrice alert: artist sold above estimateThe client runs one of the art world's longest-established market-data platforms. It tracks auction results, works for sale, artist histories and exhibitions across more than 950,000 artists and tens of thousands of auction houses, galleries and venues. Collectors, advisors, dealers, galleries and auction houses rely on it daily, on a freemium subscription model.
- Keep a very large, data-heavy platform growing while its user base passed 4 million.
- Replace a legacy alert system that could no longer handle hundreds of thousands of personalised emails a day.
- Give the internal team one reliable system to manage artists, artworks, auctions, imports and moderation.
- Launch new revenue lines, including a self-service product for art dealers and AI-powered market insights, without disrupting the core platform.
WeyBee provides a dedicated team that works as part of the client's product organisation. The team works across a .NET, Python and Next.js stack on AWS. It has delivered five major streams: the core platform, the internal content management system, a rebuilt alert engine, a completely new dealer product, and an AI chat for premium subscribers. Over time the platform moved to 54+ microservices across 9 business domains.
Search millions of artworks, follow artists, view price trends and manage personal collections, with premium data gated by subscription tier.
The system the operations team uses daily for artists, artworks, auctions, accounts, campaigns, bulk imports, moderation queues and deduplication.
A rebuilt, scalable pipeline sending 300,000+ daily emails, with timezone-aware delivery, tier-based content rules, user filters and an operations dashboard.
A new end-to-end product: public dealer presence, inventory and listing management, image uploads and buyer-inquiry leads, with its own admin CMS, authentication and deployment pipeline.
Premium subscribers ask questions in plain language and get structured answers with artist overviews, price charts and live auction data. Every session is logged for cost and quality review.
Stripe and PayPal subscriptions, engagement analytics and SSO for internal staff.
An AI market-insights
chat for premium subscribers
Premium subscribers ask about artists and prices in plain language and get structured answers with charts and live auction data. We built the chat as a product feature, with cost and quality tracked from the first session.
Each answer combines an artist overview, price charts and current auction lots from the platform's own database.
LLM providers sit behind an abstraction layer, so models can be switched or combined without touching the product.
Every session is logged with its running cost, so the feature stays profitable as usage grows.
The chat is part of the premium plan, turning AI into a reason to upgrade rather than a cost centre.
