The Weekly CFO Newsletter
The CFO Tech Stack weekly newsletter delivers one email every Monday with the week's most important benchmarks, founder finance playbooks, and CFO tool reviews — written for founders and finance leaders at high-growth companies.
What you get every Monday
One email. Sent Monday morning. Written by the CFO Tech Stack team — operators who have run finance at Series A and Series B startups, not generalist finance journalists. Each edition covers one benchmark drop, one founder playbook (the kind of thing a fractional CFO would charge $500/hour to explain), and one short note on a CFO tool we tested in the past week.
The newsletter is deliberately focused on startup finance — not personal finance, not crypto, not the broader economy. We cover the metrics that move at the seed-to-Series-B stage: burn multiples, runway policy, CAC payback, net revenue retention, fundraise timing, board pack cadence, and the software choices that change how finance work gets done at a 20-person company.
We cap the email at 600 words so it reads in under five minutes. No tracking pixels beyond the unsubscribe link. No upsells in the body — when we have a relevant paid product, we mention it in a single line at the bottom and move on.
Past editions have covered median burn multiples by stage, the post-HiBob migration playbook for Mosaic users, founder-friendly 13-week forecast templates, AI CFO versus fractional CFO pricing resets, CAC payback benchmarks for B2B SaaS, and annotated walkthroughs of the board decks investors actually read. The full archive is included below so you can scan recent issues before subscribing.
