Daily Prompt Pack: Investor Updates – Write the monthly email your backers actually answer

Most investor updates get skimmed because they bury the ask. Today’s pack is about investor updates: one prompt each for Claude, ChatGPT, and Cursor to get a short, honest email out the door in under an hour.

[Claude]

Below are my raw numbers for this month: MRR, new customers, churned customers, cash on hand, and burn. Write a 250-word investor update with sections for Highlights, Lowlights, Metrics, and Asks. Lead with the single most important number. Be plain about what went wrong, and end with exactly three specific asks tied to named goals.

[ChatGPT]

I run a 6-person SaaS startup with 14 months of runway. Draft three versions of the Asks section of my investor update: one for warm intros to enterprise buyers, one for a senior engineering hire, one for feedback on a pricing change. Each ask should be under 40 words and name the exact person type, deadline, and what a yes looks like.

[Cursor]

Build a small Python CLI that reads metrics.csv (month, mrr, customers, churned, cash, burn) and prints a month-over-month table with percent change, runway in months, and a one-line flag for any metric that moved more than 15 percent. Output a markdown block I can paste straight into an email. Add a sample metrics.csv with six months of data.
