Grenier's model for why traditional CMOs fail at product-led companies and what a 'growth CMO' does differently. The core shift is treating marketing like agile product development: every investment (even brand) is data-instrumented and immediately iterated on, experimentation applies to the whole funnel rather than just new channels, and marketing is fused with product rather than siloed. The timeless craft of understanding customers stays the same; only the operating cadence changes.
Origin
Adam Grenier's synthesis from watching world-class traditional CMOs join startups and fail to fit. He recommends the book 'Hacking Marketing' (Scott Brinker) on running marketing on agile, and points to Reforge and Maven courses.
Core principles
- 01The old four-Ps world treated product as a slow, separate science group; today product and marketing are one and the same and must be married at the hip.
- 02Brand is a consistent ongoing investment to be iterated, not a one-off campaign with terminal learnings.
- 03Data-driven means instrumenting even hard-to-measure things — retention, brand, the consideration funnel — not just landing-page clicks and sales.
- 04Almost any strong marketing leader can become a growth CMO; the differentiators are comfort with chaos and willingness to get back in the weeds.
How to run it
- 1
Instrument everything with data
Make data part of the DNA of all marketing, including retention, brand, and the consideration funnel — things you can't measure exactly like a click but absolutely can measure.
Pro tip Separate 'data-driven' from 'performance' — in marketing, 'performance' wrongly reads as anti-brand; being data-driven includes brand.
- 2
Adopt an agile iteration cadence
Keep long-term vision but run everything — landing pages, sales storytelling, logo, brand — on an agile, regularly-iterated basis validated by data, because real-time product-driven markets change fast.
Pro tip Learn agile product development directly (e.g. via 'Hacking Marketing', Reforge, or Maven) so you can apply sprint thinking to events, brand, and campaigns.
Watch out If you aren't iterative and thoughtful as a marketing leader in a product-driven company, you'll get eaten alive.
- 3
Experiment across the whole funnel
Extend experimentation beyond 'try a new channel' to the brand, the funnel, and every internal and external element — not just the top of the funnel.
Pro tip Treat trying a new channel as only one narrow form of experimentation; ask how you experiment with brand and the full funnel too.
- 4
Marry marketing to product
Integrate marketing with product as one function rather than two teams that merely 'work together', since in product-led companies the product is the company and marketing touches every piece of it.
Pro tip When hiring, probe how a candidate from a non-product-close background plans to adapt to working with the product team — good ones will figure it out with you in the interview.
Watch out If your CMO and product leader aren't married at the hip, you miss huge opportunity and consistency; renaming everything 'growth' or 'PLG' just dilutes marketing's value.
In the wild
Grenier watched multiple companies bring in absolute world-class traditional CMOs who didn't fit or succeed. Probing why, he found they tried to run marketing the way a traditional CMO would for a company at a different stage — treating brand as campaigns with terminal learnings rather than continuously iterated investments.
→ The mismatch quickly eroded trust with the marketing organization; product-led companies need a growth CMO instead.
Grenier advises marketing leaders worried about their fit to go learn agile product development via a book like 'Hacking Marketing' and courses at Reforge or Maven, without needing to become a product manager themselves.
→ Understanding those systems makes leaders think differently about running marketing and become exponentially better at working with the product org.
Common mistakes
Treating brand as a campaign with terminal learnings
Traditional CMOs drive learnings and stop; a growth CMO immediately follows each brand investment with the next iteration. Treating brand as a one-off action forfeits the compounding of fast product-style iteration.
Keeping marketing and product in separate silos
Operating marketing and product as two wildly different things — even while claiming to 'work together' — misses tons of opportunity, because in a product-led company the product is the company and marketing is integrated with every piece of it.
Is it for you?
Best for
Founders hiring marketing leadership at product-led startups, and marketing leaders adapting from traditional environments.
Not ideal for
Direct-to-consumer brands where a more traditional CMO remains well suited.
From the transcript
“we've brought in CMOS that in all ways are like absolute world-class CMOS and they don't last they don't fit”
“everybody when they think about brand they think of it as an action not as like a consistent ongoing investment”
“a growth CMO is looking at each brand investment is how do you then immediately follow that up with the next one”
“when we take things like like retention and and even brand and like the consideration funnel and yes you can't you can't measure those exactly…”
“the idea of experimentation is like trying a new channel it's not like how do we experiment with our brand how do we experiment with…”
“product is no longer a part of marketing but it's actually like they're married at the hip”
“if you're CMO and you're product leader aren't married at the hip you're just missing out on just tons of opportunity”
“there's a a book called hacking marketing I think I'll I'll confirm that but it's essentially like how to run a marketing team on agile”
