About

A studio for audience evidence, not slide filler

Castly Wavehub Institute began as a private workshop circuit for CRM and media leads who tired of personas built from assumptions. Today we host structured programs that insist on provenance tables, diary rubrics, and overlap audits before any brief hits a channel plan.

Principles we defend in critiques

  • Evidence before polish—pretty decks without provenance get sent back.
  • Operational kindness—cohorts move fast, but calendars stay humane.
  • Transparent limits—we say when a method is the wrong tool for the job.
  • Shared vocabulary—CRM, media, and product read the same matrix.

Milestones

  1. 2019 — First invite-only workshop for CRM leads rebuilding lifecycle journeys after a merger.
  2. 2022 — Hybrid studios launched with bilingual mentor notes and glossary tabs baked into every module.
  3. 2025 — Audience Evidence Studio track introduced after CFO reviews kept blocking persona decks without provenance.
