Ran marketing ops and analytics at three companies between $2M and $80M ARR. I write the spreadsheets, then I write about them.
About Growth Metrics Lab
Prove what marketing is worth — with numbers that hold up.
Growth Metrics Lab covers growth & marketing analytics: roi, ltv, cac, channels. The publishing rule we hold ourselves to is simple: if we can't show the math — the formula, a worked table, and the assumptions behind it — we don't publish the claim. "Industry benchmarks" without a denominator don't count as evidence.
How we work
Every framework starts life as a spreadsheet defending a real budget. We spell the formula out in the article, work it through with concrete numbers you can copy, and list the assumptions in a box so you can disagree with them. When we quote a benchmark, we say where it came from, who's in the sample, and whether the sample only contains the survivors.

Independence
We're part of an openly-operated portfolio of trade publications and some vendors we cover sponsor us. That relationship is disclosed, sponsor links are tagged as sponsored, and no sponsor gets editorial input. The details are on our editorial standards page.
