Daily Prompt Pack: Investor Updates – Write Updates Investors Actually Read

Most founder updates read like a changelog nobody asked for. Here is how I write mine so investors actually respond, with three prompts you can run today.

I run a B2B SaaS with 14 customers and $38k MRR. Draft my monthly investor update from these raw notes: [paste metrics, wins, misses, asks]. Structure it as: 1) one-line headline, 2) what shipped and why it matters, 3) the one metric that moved, 4) the honest miss, 5) one specific ask. Keep it under 350 words, no fluff, no corporate filler. Output as a plain-text email I can send as-is.

Here is my last investor update: [paste]. Rewrite it so a busy angel can skim it in 30 seconds. Lead with the single most important number, cut every sentence that does not carry information, and end with one clear ask. Keep my voice, do not add hype. Output two versions: a 200-word email and a 3-bullet Slack-style summary I can post in our investor channel.

Build a reusable investor-update template as a markdown file in this repo. It must have sections for headline, metrics table (ARR, churn, burn, runway), shipped items, risks, and asks. Add a script that reads a metrics.json file and fills the template automatically, flagging any metric that changed more than 20% month over month. Output the template file and the script.
