Mostly Metrics

What it is.

CJ Gustafson writes Mostly Metrics for 75,000 readers, and the audience skews finance. That's the reason to read it: these are the definitions your CFO is using.

Issues run several times a week and cover metric definitions, public company breakdowns, and the awkward operational stuff like comp transparency and auditing an AI bill.

It's free to read and the archive is open, so you can look up a definition before a board meeting.

What you get.

  • Metric definitions with the math worked through
  • Public company and S-1 breakdowns, useful as benchmarks
  • Writing on AI cost, which is now a line item marketing gets asked about
  • Operational pieces on comp, hiring, and managing upward
  • Free access with an open archive

Why do finance and marketing disagree on CAC?
Strengths
  • Gives you the definitions your CFO is already using, so the argument gets shorter.
  • 75,000 readers including finance leaders, which is a different room from marketing.
  • Shows the math instead of asserting a benchmark.
  • Free, with an open archive you can look things up in.
Limitations
  • Finance-led, so a chunk of every month is IPO and public company material.
  • Several sends a week, which is a lot if you only want the definitions.
  • Little here on channels, creative, or campaign execution.
  • No stated schedule, so the volume varies week to week.
Skip this if
  • Skip it if finance and marketing already agree on your definitions.
Ideal for
