Startup Founder Brief

Use this skill when the user needs a compressed strategic readout, not a full framework walkthrough.

Use when

• A founder needs a brief to align internal or external stakeholders.
• The startup strategy has been discussed and now needs synthesis.
• The user wants a crisp memo that states the thesis and risks clearly.

Do not use when

• The startup still lacks even basic problem and segment framing.
• The task is a detailed product or delivery artifact.

Brief failures to avoid

• summarizing everything with no prioritization
• hiding the biggest strategic risk
• turning weak assumptions into confident claims
• producing a pitch instead of a decision memo

Workflow

1. State the thesis

Write:

• what startup we are building
• for whom
• why it could matter now

2. Name the strategic choices

Include:

• primary segment
• value proposition
• GTM motion
• revenue logic if relevant

3. Surface the risk picture

Call out:

• weak assumptions
• execution risks
• external threats

4. Attach metrics and proof

Summarize:

• North Star direction
• leading indicators
• what evidence currently supports the thesis

5. End with next tests

Do not end with generic "continue learning." Name the few next validation steps that matter most.
