Three audiences. One evidence base.
Arc serves the book's three audiences – marketers and communicators, business leaders and executives, and policymakers. The evidence never changes between them; the questions do. A marketer asks whether the message will land. A business leader asks where the value sits. A policymaker asks who is being missed. Same tables, same citations, different reading – and the tools below are signposted for each.
Marketers and communicators
You're here toMake campaigns land beyond the green bubble – with the 84% of Britain the category's marketing keeps missing.
- 1Profile the customer you're briefing for
the trigger brief, the say and don't say, the frame
- 2Run your copy through the Message Lens
which segments it naturally appeals to, and the language working against you
- 3Check where the category sits
cited evidence, the adoption curve, and how each segment hears it
Watch forAppeal is relative, not moral – leaving a segment cold can be a deliberate choice. Arc's job is to make it a choice, not an accident.
In build for youSegment-targeted copy adaptation – pick the audiences, and an AI grounded in the trigger briefs reworks the prose, showing its inputs.
Business leaders and executives
You're here toFind growth that creates value fairly – for the customer first, with a fair share captured as profit.
- 1Size the category opportunity
what is proven, what is stalling, and what the rest of the world already fixed
- 2Read the customer's transition headroom
what remains of their journey, and where the joint win sits
- 3Understand the models underneath
what each lens sees, what it misses, and what is in build
Watch forValue follows carbon, never wealth – headroom is the opportunity to serve the next step, not a screen. That rule is published on the method page and it stays.
In build for youThe Value Lens commercial view – cited £ ranges per headroom step, arriving only with citations.
Policymakers
You're here toMove adoption and distribute the transition fairly – spending public money where it actually changes behaviour.
- 1Start with the category barriers
the spark gap, the space problem, and international proof that policy moves markets
- 2See who current framing misses
test the public messaging; watch which segments go wary
- 3Read the population honestly
seven segments with population shares, evidence states, and no forced conclusions
Watch forThe engine says less when it knows less – insufficient information renders as insufficient information, never as a confident answer. Policy deserves the same honesty.
In build for youA per-segment policy view – where each segment is supported by existing schemes, and where they fall through the gaps. Researched and cited, like everything else.
Whoever you are, the working is always on the page – every number cited and dated, every rule published, every gap shown rather than filled.
