Matt Lerner on Why 90% of Your Growth Work is Wasted Effort

There Are Only Six Channels in the World

Most founders overthink channel strategy. They'll debate paid versus organic, content versus influencer, product-led versus sales-led until they've burned half their runway.

Matt Lerner cuts through it: "There's really only like 6 channels in the world. If you think about how are the ways you find out about stuff, you hear from a salesperson, some partner brings you in 'cause to enable you to do something, you see some ads, you do a Google search, or there's some content or inbound paid ads, or maybe hear about it from an influencer. That's really kind of it."

If you just take these 6 channels and like cross off the 4 or 5 that probably don't work, you've got your channels. And that's like 1% of the challenge. 99% of the challenge is getting it to work.

Can't afford salespeople? Cross it off. No one's Googling anything related to your product? SEO is out. Tight unit economics with long payback? Paid won't work. In an hour with your co-founders, you can eliminate most channels and focus on the one or two that might actually move the needle.

Your North Star is Probably Wrong

The biggest mistake Lerner sees? Startups choosing revenue as their North Star metric. It sounds logical. You're a business, you need money. But it's a trap.

"There's so many ways to deliver revenue without actually delivering customer value," Lerner explains. "And as an early stage startup, decreasing password sharing or bundle or upsells, things like that, you know, they'll make you a little more money, but no one's gonna hypergrow because they shut down password sharing."

The second problem: alignment. Tell six functional heads to brainstorm ways to make money, and you'll get six different strategies pulling in six directions. A startup can't move in six directions. But ask everyone how to increase weekly active users or tables shared, and suddenly they're having a productive conversation about the same value chain.

Lerner's test: "How would a normal customer behave if they absolutely loved your product? And how many of them are behaving that way? And track it in cohorts and make it go up over time." That's your North Star. Not revenue. Not vanity metrics. Behavioral proof of value delivery.

Friction Can Be Your Friend

The growth world loves to optimize for frictionless experiences. Fewer form fields. Shorter onboarding. One-click everything. But Lerner points to companies like Noom and Calm, which put users through 20 to 30 questions before they see the product.

"These long flows are actually really good at building intent," he says. "And they A/B test and optimize the shit out of these flows. And it is more of an onerous user experience."

If you go to the doctor and you say, well, it hurts here. And then the doctor says, well, does it hurt when you do this? And does it hurt more at night? And if you're like, yes, yes, yes, then you believe whatever the doctor says is more likely to be accurate. So they're actually showing that, yes, we understand you. And that builds intent.

This isn't about making things harder for the sake of it. It's about recognizing that if you sell a $10-per-month product, you can't afford salespeople to answer objections and build intent. Your onboarding flow has to do that work. Each question qualifies the lead, surfaces their specific pain, and demonstrates that you understand their problem. By the time they hit the paywall, they're pre-sold.

The Three Types of Founders Who Fail

After years at 500 Startups seeing hundreds of companies up close, Lerner identified three patterns of failure. First: overthinkers. Usually former VPs of product from big companies or strategy consultants. They measure twice, cut once, then measure again. They debate for months. Speed isn't in their DNA because they've never needed it before.

Second: underthinkers. They have a bias for action, which sounds great. They build something, it doesn't work, so they build the next thing. And the next. The problem? "Each time you build something else, you're making the product more complex, you're making the experience more complex, you're making the organization more complex, you're making the sales process more complex, the value proposition, and it's slowing you down at a time where you need nothing more than speed."

Third: hire-and-delegate types. They're humble. They admit they're not experts. So they hire six functional heads to run their best practices. But without clear product-market fit, those six people will optimize six different things, and the trade-offs bubble right back up to the founder. "A startup needs to be good at 1.5 things tops," Lerner says.

Find the Locksmith Moment

Early in his PayPal days, Lerner walked home to his San Francisco apartment and found a sticker over the gate lock: "24-hour emergency locksmith" with a phone number. Someone had squirted glue in the lock. The locksmith could have bought transit ads or sponsored podcasts. But she found the exact moment of highest need and put herself there.

I thought, that's the key. So every successful startup finds this kind of exact moment of highest need and figures out a way to insert themselves there.

To find your locksmith moment, Lerner uses survivorship bias. Interview people who actually signed up for your product. Use jobs-to-be-done interviews to understand their problem. Pull out the verbs. What were they trying to do? A good headline completes the sentence "now you can." Now you can close out your quarter in minutes, not days. Now you can file VAT returns without an accountant.

Then test those messages fast. Mock up landing pages. Run cheap ads for $500 in a week. See what resonates. The 10% of work that will drive 90% of your growth isn't hiding in some complex strategy deck. It's in those customer interviews and rapid tests, finding the moment when someone realizes they need you more than anything else.
