When, Why, and How to Bet on New Growth Channels
Lenny Rachitsky interviews growth and marketing leader Adam Grenier about choosing and testing emerging acquisition channels, defining the modern “growth CMO,” and navigating burnout and depression in high-growth tech careers.
Adam shares a three-part framework for deciding whether to invest in new channels (like TikTok, OTT, influencers, Clubhouse), emphasizing channel–customer–company fit, channel maturity and incentives, and a startup’s own capabilities and risk profile.
He argues most product-led companies need CMOs who are deeply data-driven, experimentation-minded, and tightly integrated with product, rather than traditional campaign-first marketers.
They close with an honest discussion of mental health, how to distinguish burnout from depression, and practical practices—therapy, community, introspection—to build a sustainable career in tech.

Study a channel’s DNA—maturity, stability, and monetization—to size the risk.
Early-stage channels change rapidly, break often, and may disappear; understanding where they are in their lifecycle and how they plan to make money helps you decide how much to invest and how to partner with them.

Look for directional momentum, not perfect attribution, when testing new channels.
Early experiments are about “fishing” for signs of traction—growing room sizes, improving engagement, cheaper installs—not statistically perfect models; if you see no directional improvement within a quarter, pause and reallocate.

Re-evaluate product–market fit whenever the broader market shifts.
Economic or contextual changes can invalidate yesterday’s product–market fit; assuming you still have it and trying to ‘fix’ growth with a new channel is dangerous if your underlying customer and value proposition have shifted.

Modern CMOs in product-led companies must operate like growth leaders.
Effective “growth CMOs” are data-driven, iterative, and deeply integrated with product development, treating brand and campaigns as ongoing experiments rather than one-off events, and sharing an agile roadmap with product.

Burnout and depression often look similar—watch your adaptability and motivation.
Adam distinguishes exhaustion (still energized by new challenges) from depression (withdrawing from activities you normally love) and recommends therapy, openness with friends/partners, and self-awareness to diagnose and address the root cause.

One of the biggest pieces of advice I'm giving to people that are like, "How should we adjust our marketing with the economic changes?" And things like that, I was like, "Start by assuming you no longer have product-market fit." (laughs) Because you had product-market fit in a different market. It's a different market now, so you have to start over, and, and then hopefully you do, or it's pretty close to it, and you just have to adjust a couple of things, and you could be right back on track. But, like, if you just assume, like, you need to launch a new channel to fix this problem, like, you're gonna be wrong. Because, like, your entire customer base changed, not just the next 10% of customers that you're looking for. (instrumental music)
Welcome to Lenny's Podcast. I'm Lenny, and my goal here is to help you get better at the craft of building and growing products. I interview world-class product leaders and growth experts to learn from their hard-won experiences building and scaling today's most successful companies. Today, my guest is Adam Grenier. Adam was head of growth marketing and innovation at Uber, where he basically built their growth marketing infrastructure and the team from the ground up. Then he went on to VP of product and marketing at Lambda School, and most recently, he was VP of marketing at MasterClass. These days, Adam advises companies large and small on growth and marketing strategy. In our conversation, we cover how to decide when to try new and emerging acquisition channels like TikTok, VR, newsletter ads, and how to go about testing them out. We get into the growth CMO role, which is an emerging role that Adam has helped pioneer, and we get into some real talk about burnout and depression and mental health issues that often come with working in tech. This was a really powerful and insightful conversation, and I learned a lot from Adam, both as an operator and as a human. I can't wait for you to hear this episode. And so with that, I bring you Adam Grenier. This episode is brought to you by Whimsical.
