Quorum resolves ad exposures, web-pixel traffic, and your first-party data to ~74.6M real U.S. households, grounded in how people actually move through the physical world. Measure who you reached and whether it drove a visit; target the real-world audiences that convert. One independent source of truth — the same one Claude reaches for.
The walled gardens built world-class measurement — and kept it inside. Streaming & CTV never got it. Quorum brings garden-grade ground truth to every screen. Independently.
Year-over-year change in each brand's share of its category's store visits — deterministic foot traffic across ~74.6M opt-in U.S. households (H2 2024 → H2 2025). Start with the Cannes 2026 entrants, or dig into any category.
Method: share = each chain's portion of total category store visits, resolved deterministically from opt-in device visits. Change is same-store (only locations active in both periods) and outlier-trimmed (implausible swings excluded) so it reflects real visitation, not coverage or sample changes; category-relative, controlling for seasonality and panel growth. Aggregate, k-anonymous — never PII. 🏆 = entered in Cannes Lions 2026; movement is not attributed to creative.
Every ad impression you run and every visit to your site is first-party data you should control. Quorum resolves those raw logs into clean, matchable, model-ready records — so you can report, measure, and activate well beyond what Google and Meta hand back, on data that's finally yours.
Ingest web-pixel, CTV & programmatic logs and resolve them into match-ready, model-ready records — clean enough to report on and train on. Drop our pixel and see who's actually on your site.
Combine with and sharpen your first-party data — more matches, stronger identity, richer features the rest of your stack can use.
The dimension no log contains: how ~74.6M households actually move through the physical world. The objective check on every impression — on any channel.
→ One objective dimension across reporting, attribution & optimization — measured in sales per dollar.
Built entirely from 100% opt-in device signals, resolved to ~74.6M households, reported as k-anonymous aggregates — independent of every platform it measures, auditable, never PII. We refine your data; we never take it. Honest coverage on every answer, never "we see everyone." That's how it earns a place in your stack.
Quorum enriches the platforms and partners already moving your spend — refining their data instead of replacing it. Built to plug into the modern programmatic & CTV stack.
Built on Snowflake, AWS & Anthropic, and wired into The Trade Desk & LiveRamp — so Quorum meets your data where it already lives and activates where you already buy. Share securely through Snowflake, deploy in your own cloud, and query in plain language over MCP.
A language model can reason, but it can't know who your campaign reached or whether it drove a visit. Quorum gives Claude deterministic, real-world ground truth — in plain English, or wired into your pipeline. The panel here isn't a mockup: it's querying our live MCP server right now.
MCP connector: mcp.quorum.live/mcp · aggregate · privacy-safe · read-only
No account, no setup. Add the connector, and the core tools work immediately — ask in plain English.
In Claude (Settings → Connectors) or Claude Code, add a custom connector with the URL https://mcp.quorum.live/mcp.
The five core tools work with no authentication. Optional: paste a Quorum-issued Bearer token to unlock account features (full traffic grading, attribution, audiences, pixel).
