## Who we speak to
Pro traders. Never "creators". They are quantitative, sceptical, and short on time.

## How we sound
Precise. Evidence first. No hype. We state what the platform does and what the numbers prove, then stop.

## The lines
Tagline: Prove the edge. Then trade it.

Descriptor: The professional workspace for building institutional-grade quantitative strategies. Validate against four years of SONAR cross-venue data, then run it on your own account at your own broker.

Supporting lines:
- Four years of data before a dollar of risk.
- You keep the alpha. We handle the rails.
- Validated, versioned, and execution-ready.
- Run it on your own account, at your own broker.

## Say this
Pro trader. Validate strategy. Run it on your own account. Backtested on four years of data.

## Never this
Creator. Unlock your trading potential. Guaranteed returns. Get rich with AI signals. Revolutionary alpha.

## Rules
1. Lead with the number, not the adjective.
2. Name the mechanism. "Deflated Sharpe gate" beats "smart validation".
3. Never promise a return. Ever.
4. No emoji, no exclamation marks.
5. Sentence case everywhere except mono labels, which are uppercase.
