Quorum vs Placer.ai: which one fits your question?

Short answerUse Placer.ai when your question is about places: trade areas, site selection, competitive visit share, market research. Use Quorum when your question is about your own media: which CTV, web, programmatic or billboard exposure drove households into your stores. Both offer foot-traffic attribution; they start from different data.

Where Quorum is the better choice

You run streaming, programmatic or billboard media and need to know which of it drove visits.
You want web traffic and store visits on the same household spine, so every channel reports the same number.
You want to turn the households that converted into a targeting audience.
You want to ask the data questions from your own AI assistant instead of a dashboard.

Using both

They do not conflict. A retailer can use Placer.ai to decide where to open and Quorum to measure the media that fills the store.

Questions

What is the difference between Quorum and Placer.ai?

Placer.ai is a location intelligence platform built around visitation data for places, used for site selection, trade areas, market research and campaign lift. Quorum starts from an advertiser's own media: it ingests CTV and programmatic impression logs, website pixel traffic and billboard placements, resolves them to about 74.6 million opt-in U.S. households, and measures whether those households visited stores.

Is Quorum a Placer.ai alternative for ad attribution?

For measuring which of your own ads drove store visits, especially CTV, web and billboards measured on one household graph, yes. For site selection and broad location research, Placer.ai is built for that and Quorum is not.
