The Moat Myth: Why Network Effects Are Overrated and Product Quality Is Underrated

Are network effects or product quality the stronger competitive moat?

Ask a venture capitalist about moats and they'll immediately say "network effects." It's become the default answer -- so reflexive that it's lost most of its meaning. Every marketplace claims network effects. Every social product claims network effects. Every platform with more than two users claims network effects.

But Hamilton Helmer, who literally wrote the book on competitive strategy, has a sobering correction: most companies that claim network effects don't actually have them in any meaningful sense. And meanwhile, companies like Superhuman, Stripe, and Granola are building durable competitive advantages through something the strategy textbooks barely mention -- product craft so exceptional that it creates its own distribution.

The moat conversation needs a reframe. Here's what the best builders and strategists actually think.

Are network effects the primary source of competitive advantage, or can product quality and craft serve as a genuine moat?

The 4 Positions

1 / 4

Network Effects Are Overstated -- Most Companies Don't Have Them

Hamilton Helmer (Author of *7 Powers* · Strategy Capital)

Advocates: Hamilton Helmer (Author of 7 Powers, Strategy Capital)

Hamilton Helmer draws a distinction that should make most platform companies nervous. There's a difference between "network effects" (the product gets better with more users) and "network economies" (a structural power that creates both a benefit and a barrier). Most companies have the former without the latter.

"I think you could turn almost anywhere and get some modest network effects and any platform business would probably likely have some modest network effects. You asked me about Uber and Lyft, I'd say that they probably have network effects involved but not network economies."
Hamilton Helmer

The Uber/Lyft example is devastating. Both have network effects -- more drivers means faster pickups, more riders means more demand for drivers. But neither has network economies as true power. The proof: they've competed head-to-head for over a decade, both burning billions, with neither achieving a durable structural advantage over the other. If network effects were a real moat for ride-sharing, one should have driven the other out of business long ago. The fact that both survive suggests the network effects are real but modest -- not powerful enough to constitute strategic power.

"You're on a treadmill and if you stop running on that treadmill, you get creamed, but it's not power. The things that drive operational excellence can be mimicked."
Hamilton Helmer
▶ 00:00:20

"Power requires a benefit and a barrier. Warren Buffett famously said he looks for economic castles protected by unbreachable moats."
Hamilton Helmer
▶ 00:00:04

Helmer's framework insists that power requires two things: a benefit (you're better) AND a barrier (competitors can't easily replicate why you're better). Most "moats" fail the barrier test. Being faster, having a better team, or executing better are all benefits without barriers -- they can be mimicked. The competitor just has to run as fast as you on the same treadmill. That's exhausting and expensive, but it's not a moat.

This framework has profound implications. It means that many of the things companies celebrate as competitive advantages -- speed of execution, team quality, operational excellence -- are actually just table stakes. They keep you in the game but don't give you a durable edge. True power comes from structural advantages that competitors can't replicate even if they understand them.

When This Applies

Your product genuinely becomes better as more people use it, AND this advantage is hard for competitors to replicate. Marketplaces with strong local density, communication platforms with established groups, data networks where more users mean better algorithms. Rare and valuable when real.

Product Craft CAN Be a Moat When It Creates Its Own Distribution

Peter Deng (Product leader · OpenAI/Instagram/Uber)

Advocates: Peter Deng (Product leader, OpenAI/Instagram/Uber)

Peter Deng challenges the strategists with a builder's perspective. Some products are so well-crafted that they overcome massive distribution advantages held by incumbents. The craft itself becomes the distribution mechanism through word of mouth.

"I do believe there is a level of product craft that will make it so that it's just worth it to switch or try something else."
Peter Dengon Lenny's Podcast (arguing product craft can overcome distribution advantages)

"They have these little edges, set it down just right, and they've really figured out a way to really make it so delightful that it's like, 'Yeah, I will install this piece of software. Yes, 100% I will talk to my friends about this because it is so life-changing.'"
Peter Dengon Lenny's Podcast (on how delight creates organic distribution)

Deng points to Granola as the example. Despite Google Meet, Microsoft Teams, and Zoom all having built-in AI meeting features with massive distribution advantages, Granola wins because the "tiny little product craft delightful things" are so good that people actively install additional software and evangelize it to colleagues. This is a David-vs-Goliath story powered entirely by craft.

The key mechanism: craft creates delight, delight creates word of mouth, word of mouth creates distribution. This is a moat that Hamilton Helmer's framework might categorize as "brand" power -- but it starts with product quality, not marketing. The brand emerges from the product, not from a campaign. And because the brand was earned through quality rather than bought through marketing, it's more authentic and more durable.

Deng's Instagram experience reinforces the point. Instagram didn't win because of technical superiority or marketing spend. It won because the craft -- the filters, the square format, the deliberate simplicity -- created something people genuinely wanted to share. The craft created the distribution, not the other way around.

When This Applies

Your category has large, complacent incumbents who've stopped innovating on user experience. Users are dissatisfied enough to switch. You can create "install additional software" levels of delight. Works best early when you can win fans one at a time through word of mouth.

Accruing Benefits Create the Real Defensibility

Sarah Tavel (General Partner · Benchmark · former Pinterest)

Advocates: Sarah Tavel (General Partner, Benchmark; former Pinterest)

Sarah Tavel introduces a more nuanced model from her hierarchy of engagement. The most defensible moats come from accruing benefits -- as users invest more in a product, they build up data, connections, and workflows that become increasingly hard to leave. This is different from pure network effects because it works at the individual level, not the network level.

"When a user completes this action, it's clear that they both understand the utility of the product, and it's an action that, if they perform the action, they're very likely to come back."
Sarah Tavel
▶ 00:05:45

The accruing benefits model is powerful because it works for products without network effects. A note-taking app gets better the more notes you take. A CRM gets more valuable the more contacts and deals you track. A design tool like Figma becomes harder to leave the more templates and components you've built. Each of these products creates individual-level switching costs that grow over time.

These switching costs are legitimate moats because they satisfy Helmer's dual requirement: there's a benefit (the product is better for you personally because of your investment) and a barrier (leaving means losing that accumulated value). The barrier is proportional to the user's investment, which means the most engaged users are the hardest to lose -- exactly the users you most want to keep.

Tavel's hierarchy also explains why some products feel "sticky" even when competitors offer better features. The user who has 10,000 notes in Evernote faces a massive switching cost even if Notion is objectively better. The accrued benefits create an inertia that feature comparison alone can't overcome. This is why new entrants in established categories often need to be dramatically better, not just slightly better, to overcome the switching cost barrier.

When This Applies

Your product stores user-generated data, customizations, or relationships that increase in value over time. The more users invest, the harder it is to leave. Works across categories and doesn't require network effects.

Brand Through Quality Creates Durable Distribution

Rahul Vohra (CEO · Superhuman)

Advocates: Rahul Vohra (CEO, Superhuman)

Rahul Vohra's Superhuman proved something many strategists thought was impossible: you can build a venture-scale business in a commodity category (email) by being dramatically better. The moat isn't network effects or switching costs -- it's brand power created through quality.

"What is it that creates true virality? It's not viral mechanics, it's word of mouth. It is brand. This is how you can kickstart a brand."
Rahul Vohra
▶ 00:49:49

Superhuman positioned around a single attribute -- speed -- and obsessed over every detail to deliver on that promise. The result was a cohort of superfans who became unpaid evangelists. Their willingness to pay a premium ($30/month for email) and tell everyone about it created a self-reinforcing distribution loop.

This is the craft-to-brand-to-moat flywheel: exceptional quality creates a passionate early cohort, that cohort builds the brand through word of mouth, and the brand creates distribution that compounds over time. The brand itself becomes the barrier in Helmer's framework -- you can't replicate someone else's brand even if you replicate their product.

The Superhuman example is important because email is arguably the worst possible category to try this in. Gmail is free, well-made, and has billions of users. If craft-driven brand power can work in email, it can work almost anywhere. The lesson isn't specific to email -- it's that any commodity category can be differentiated by quality if the quality is exceptional enough to generate word of mouth.

When This Applies

You're in a commodity category where functional differentiation is hard to sustain. An early cohort of superfans can build a brand that creates distribution advantages no competitor can buy. Requires patience and premium positioning.

The Synthesis

The moat conversation has been corrupted by lazy thinking. "Network effects" has become a magic word that founders invoke to make their business sound defensible. But as Helmer demonstrates, most network effects are too modest to constitute real power.

Layered Advantage

Why is 'network effects vs. product moat' a false choice?

Craft as Spear Tip

What role does craft play in building structural moats?

Magic Word Corruption

Why has 'network effects' become a dangerous term?

The most durable moats are built by layering multiple sources of advantage, with product quality as the foundation. Craft creates delight, delight creates word-of-mouth, distribution creates accruing benefits, and accruing benefits create switching costs. Each layer reinforces the others.

The best companies use craft as the tip of the spear and then build structural moats behind it. Craft gets you in the door. Structural advantages keep you there. Companies relying solely on network effects without product quality are vulnerable to craft-driven competitors stealing users one at a time.

The moat conversation has been corrupted by lazy thinking. 'Network effects' has become a magic word founders invoke to sound defensible. But most network effects are too modest to constitute real power. Network economies without a great product do not prevent churn.

The Bottom Line

The companies that rely solely on network effects without product quality are vulnerable to craft-driven competitors who can steal users one at a time. The companies that rely solely on craft without structural reinforcement are vulnerable to well-funded competitors who can eventually match their quality. The winning strategy is both: start with craft, build structural moats, and keep investing in craft so the flywheel keeps spinning.

Each layer reinforces the others. This is why the "network effects vs. product moat" framing is a false choice. The best companies use craft as the tip of the spear and then build structural moats behind it. The craft gets you in the door. The structural advantages keep you there.
