Grounding Type: Product Marketing

The Message House Schema

Ask five AI tools for your product's positioning and you'll get five slightly different answers — because none of them have anything authoritative to check against. A Message House fixes that for product marketing: instead of copywriters and SDRs prompting AI with generic templates, MsgStack structures your brand positioning into a machine-readable schema that governs generation, the same structure every other canon domain follows.

Brand Grounding via Schemas

A Message House isn't a slide — it's a schema. Each pillar, claim, and proof point is a real row an AI tool can query, not a bullet point it has to guess the intent of.

Value PillarsArray<PillarNode>

Persona MappingsArray<String>

Locked Claims (Proof Points)Array<ClaimNode>

Channel ConstraintsDictionary<String, String>

FIELD VALIDATORValue Pillars

The structural pillars of the product narrative. Typically 3 to 4 distinct themes that categorize messaging claims.

Derived Artifacts (Skills)

The Message House is the source of truth; everything else is generated from it on demand, not written from scratch each time.

Competitor Battlecards

Pulls your locked proof points and known objections, so a battlecard never invents a stat your legal team hasn't cleared.

Outbound Copy

Generates emails and LinkedIn posts from the same locked pillars, so the stat in the email still matches the one in the deck.

Press & Briefs

Structures launches into press releases and partner briefs, with every claim and proof point traceable back to this domain.

Say it once. Say it right, everywhere.

Structure your positioning once, and every battlecard, email, and press release generated from it stays locked to the same facts.
