What is the difference between Rascasse and GWI?

GWI is survey research published in four waves per year, covering attitudes, lifestyle and motivations across 50+ markets with more than fifteen years of trended data. Rascasse observes behavioral signals, updates monthly, resolves to postal-code level and covers 500,000+ entities, but does not measure attitudes.

Is Rascasse a GWI alternative?

For audience location, partner discovery and demand tracking, yes — and at higher cadence and finer geography. For attitudinal segmentation, lifestyle research and long-run trended analysis, no. The two are more often complementary than substitutable.

How often is each dataset updated?

GWI publishes four waves of data per year. Rascasse updates monthly. The relevant question is how often the decision being supported is actually made — annual strategy is well served by waves, continuous in-market decisions are not.

Which has broader market coverage?

GWI states 50+ markets; Rascasse has 31 built-out markets. On entity coverage the relationship reverses, because a survey can only ask about brands included in the questionnaire while behavioral coverage extends to any entity with observable activity.

Rascasse vs. GWI: Waves or Continuous Signals?

The short answer

GWI is built for strategic consumer understanding: deep attitudinal and lifestyle profiling with more than fifteen years of trended data behind it. Rascasse is built for in-market decisions: which entities an audience overindexes on, where it concentrates geographically, and how demand moved this month. If the question is "what kind of people are these?", GWI. If it is "where and with whom do we act now?", behavioral.

Where GWI is stronger

Attitudinal and lifestyle depth. Values, motivations and self-reported lifestyle are the core of the offering, and they are not derivable from behavior.
Trended history. More than fifteen years of consistently instrumented data is a genuine asset for long-run analysis, and it cannot be reconstructed retrospectively.
Market breadth. 50+ markets against our 31 built-out markets.
Consistency of instrument. A stable questionnaire across waves and markets makes cross-market comparison clean in a way that behavioral coverage, which varies by market, does not.
Segment definition by attitude. Segments can be built on stated values, which behavioral data can only approximate through interests.

Where Rascasse is stronger

Cadence. Monthly against four waves a year. For anything in-market — campaign response, demand shift, seasonality — a quarterly wave arrives after the decision was needed.
Geographic resolution. Postal code against market and region. Site selection, out-of-home and regional test design all happen below the level a survey sample supports.
Entity breadth. 500,000+ entities against a questionnaire's brand list. For partner discovery this is the decisive difference: the interesting property is usually one nobody would have thought to include.
Public verifiability. Profiles are open without a login, so a figure used in a pitch can be checked by whoever receives it.
Machine access. A REST API, and MCP access where it is part of the agreement, so the data is queryable directly rather than exported into a deck.

The cadence question, concretely

Four waves a year means a change occurring in February is visible in the wave published for that quarter and confirmable in the next — a lag measured in months. That is entirely appropriate for strategic questions, where quarter-to-quarter noise is a distraction. It is the wrong instrument for noticing that a competitor's demand rose sharply in a specific region six weeks ago.

The distinction is not speed for its own sake. It is whether the decision is made once a year or continuously — and most sponsorship, media and location decisions are made continuously.

Used together

These two combine cleanly, because they barely overlap. GWI describes what kind of people a segment contains and what they say motivates them; behavioral data shows where those people are and which properties, brands and events they engage with disproportionately right now. A segment defined attitudinally in GWI and located geographically through behavioral data is a stronger brief than either produces alone.
