Do your fund’s messages shift from deck to DDQ to first call? This lesson gives you a compliance-grade Message House you can fill, govern, and reuse so every IR touchpoint delivers one consistent, memorable story. You’ll get a precise framework (roof, pillars, proof bricks, guardrails), real-world examples, channel-mapping guidance, and short exercises to test phrasing and compliance. Finish with a repeatable template, version-control cadence, and coaching routines that protect reputations and speed second meetings.
