The Tropos Index · Scored every day since 30 June 2026
Day 93
Every day, Tropos Index measures how 80 culturally exposed brands are received, and by whom. Then we do what no one in this category does: we publish our forecasts before the outcome is known, with a date and a probability, and grade every one in public. Including the ones we get wrong.

Pulled a children’s Halloween costume critics said evoked minstrel caricature. Its shares closed down 3.8% the following day.
Its chief executive apologised for a co-branded ad that Callaway had approved. The partnership was over within a week.
Pulled an ad after a U.S. congressman asked, publicly, how it had cleared approval.
Each one passed review. Each one was read as an attack by a specific group of people. And each was foreseeable, to anyone who knew how that group reads the world.
That isn’t a creative problem. It’s a measurement problem. Brands track reach, sentiment and share of voice. Very few can say which constituencies their coverage reaches, how those constituencies are taking it, or how that has changed since last month.
of senior executives say they know where negative sentiment about their brand is concentrated. Two years earlier, it was 56%.

A 0–100 score for each brand, computed every day from the coverage it actually receives, across three dimensions: Cultural Capital, Velocity and Resilience. Every day’s score is kept exactly as published. We never go back and revise the past.
38 named constituencies, groups defined by what they value, not by age or income: Counter-Establishment Critics, Boycott Coalitions and 36more. Each brand’s coverage is mapped to the constituencies it reaches, so you can see who is carrying your story, and who is turning on it.
When we see something forming, we write it down as a yes-or-no forecast, with a deadline and a probability, fingerprint it, and publish it the same day. Then we grade it. Anyone can check any forecast against the public record, in one click.
Don’t take our word for it
We do. Every forecast we make is on a public ledger: dated before the outcome, fingerprinted, and anchored every day in a public repository we can’t quietly edit. Open any forecast and press “Check this forecast.” Your own browser verifies it. Not our server. Yours.

Founding Pilot · Three places
There’s no fee. In return: a 30-minute recorded conversation about what was useful and what wasn’t, permission to cite the engagement (named or anonymised, your choice), and first right to a Founding Partner seat if it’s worth continuing.
Three places. When they’re taken, they’re taken. Your score never changes because you're a client, and no fee ever depends on it.The builder

Tropos Index is being built as a sovereign operation: methodology-first, founder-led, accountable to the brands and institutions that will eventually license the Index as a benchmark.
