Mackenzie Burnett on Founder

Mackenzie Burnett@ciaomack

announcing @AmbrookAg's $30M series B, led by lachy groom. instead of a fundraising video, we typed up a letter - if you're curious, give us your address (link in thread) and we'll send you some snail mail. like our customers already know, some good things take time.

Why it worked

Opens with a short, self-contained line that is easy to take in at a glance.
Uses concrete numbers instead of vague claims, which makes it credible and quotable.
Points at real customers, users or results as evidence rather than assertion.
Ends on a short line that is easy to quote and repeat.
Written from experience rather than as advice, which is harder to argue with.
Short enough to read in full without expanding, which removes a step before the point lands.

The mechanics

Hook: Announcement
Structure: Hook → Landing
Style: Conversational paragraphs at a steady pace.
Tone: concrete, corporate
Mechanisms: Specificity, Social proof
