Investor Update Generator
The investor update, drafted from the numbers you already track and gated before it sends.
01 the number that stalled
Startups that send consistent investor updates are twice as likely to raise follow-on funding (Visible platform data). The update is the first thing that slips when the month gets hard, and the silence reads as a signal even when the business is fine. Going quiet costs real odds.
02 the system, specced
The generator turns operating data into the investor update, on a cadence that holds. Point it at the numbers you already track and each month a ready letter arrives: the metrics with their movement explained, the wins, the asks, the honest flags. The draft generates live via the Anthropic API and lands in the founder's voice. You read it, fix the one thing it flags, and send. Nothing sends without you.
The checking stays under the hood: every figure traces to a source before the draft reaches you, and a claim that fails its check surfaces as one plain fix, with a button that applies it. The record view keeps the streak, one line per month, and carries every ask forward until it closes. I have written the monthly update from the operator's seat, and the system is built around the part that actually stalls: the blank page on a busy day.
