Write a monthly investor update email for {{company}}, covering {{month}}.
Inputs:
Highlights: {{highlights}}
Lowlights: {{lowlights}}
Key metrics: {{key_metrics}}
Asks: {{asks}}
Structure (in this exact order):
1. One-paragraph TL;DR (3–4 sentences, lead with the strongest signal).
2. Key metrics as a small table-shaped block — MRR, customers, runway-months, growth %.
3. Highlights (3–5 bullets, factual, no marketing-speak).
4. Lowlights (2–3 bullets, candid; investors trust honest founders).
5. Asks (each ask is one sentence with a clear who/what).
6. One-line sign-off with date of next update.
Tone: confident, factual, conversational. Under 450 words.'Lowlights' is the underrated section — investors stop reading sugar-coated updates. The candid section builds trust over time.
