Turning Your Product into Your Most Powerful Competitive Moat
Move beyond traditional barriers by building a product-led moat. Through network effects and high switching costs, create indispensable software that turns users into lifelong advocates.
If we want to build a software business that lasts for good, one simple and effective thing we can do is stop looking at our marketing budget and start looking at our product.
Here's why:
Elite companies will often rely on traditional barriers to protect their business. They buy up patents, they hoard massive amounts of capital, or they rely on aggressive sales tactics. Each of these methods provides a wall. It offers a way to keep competitors out and lock customers in.
Warren Buffett, the famous investor, provides a good example. He coined the term "economic moat" to describe the competitive advantage that a company has over other companies in the same industry. He said that a good business is like a strong castle with a deep moat around it.
For the traditional business owner, digging that moat meant lowering prices or signing exclusive distribution contracts. It provided the immediate defense they needed to keep their market share just right.
Like a king building a castle through trial and error, we often try to build our businesses through trial and error. If one marketing channel doesn't deliver the desired effect, then we adjust—like a general tweaking the deployment of their troops.
However, there is an important difference between building a moat out of capital and building a moat out of your product. When it comes to modern software, traditional moats are easily crossed. It's easy for a competitor to raise more money or copy a feature. But it can be incredibly difficult to replicate a product that has woven itself into the daily habits of its users. Perhaps we've been running Facebook ads for a month, but we still don't see a change in our retention rate. Or maybe we managed to lower our prices for 16 straight days, but we still feel stressed and anxious about our competitors.
Building a lasting business is a long race. It often takes time for the desired results to appear. And while we are waiting for the long-term rewards of our efforts to accumulate, we need a reason to trust our strategy in the short-term. We need to know we are on the right path.
And this is where a product-led moat can help.
The Product Moat: What It Is and How It Works
A product moat is a simple concept: it means your product is so good, so deeply integrated into a user's life, and so uniquely valuable that leaving it becomes painful.
The most basic format is to build a tool that solves a problem better than anyone else. For example, if we use a piece of software on Monday, Wednesday, and Friday to save three hours of work, that software becomes indispensable. As time rolls by, the product becomes a record of our productivity.
No matter what industry we are in, the key point is our product must provide immediate evidence that it makes our users' lives better. It's a signal that they are making progress. Of course, that's not all it does…
A product moat is powerful for three core principles.
It creates network effects that naturally improve the experience.
It builds high switching costs that make leaving difficult.
It offers economies of scale that make the product faster and cheaper over time.
Let's break down each one.
Principle #1: A product moat creates network effects.
Network effects naturally build a series of compounding benefits. When we look at a product and see our entire team already using it, we are reminded of its value.
Research has shown that products that connect users to one another are vastly more resilient than those that act as standalone tools. A product with strong network effects becomes more valuable with every new person who joins. The telephone is a classic example. One telephone is a useless piece of plastic. Two telephones offer a connection. A billion telephones change the world.
A product moat relies on this exact principle. When we build features that encourage sharing, collaboration, and community, the mere act of using the software sparks the urge to invite others.
Principle #2: A product moat builds switching costs.
The most effective form of retention is user investment. When we get a signal that we have customized a workspace, uploaded our data, and trained our team on a tool, we become incredibly reluctant to leave. In this way, a product moat can have a binding effect on our customers. Each small piece of data uploaded feeds their reliance on the system.
This can be particularly powerful on a bad day. When a competitor launches a shiny new feature, it’s easy to be tempted. But switching costs provide visual proof of our hard work—a subtle reminder of how far we've come with our current tool. Plus, the empty workspace we would see if we switched to a new software can motivate us to stay right where we are, because we don't want to lose our progress.
Principle #3: A product moat provides immediate satisfaction through scale.
Finally, scale feels rewarding. It is satisfying to use a product that is constantly getting faster, adding integrations, and reducing bugs because the company has the resources to out-develop smaller rivals. It feels good to watch a tool grow, and if it feels good, then we are more likely to endure the occasional hiccup.
Scale also helps keep our eye on the ball: we are focused on the continuous value rather than the one-off purchase. We are not fixated on just buying a software license; we are trying to align ourselves with the industry standard.
Best Practices for Building Your Moat
Alright, those principles sound great, but it's not necessary to fill our product roadmap with every complex feature that comes to mind. In fact, if we're already struggling to keep our product stable, then it seems like extra work to try and build complex network effects. So what should we actually build to dig our moat?
Building a product moat can help kickstart growth or keep us on track with customer retention when the market gets crowded.
We recommend using the "Time-to-Value Rule," which suggests we scale our onboarding down until it takes two minutes or less for a user to experience a "wow" moment. We can build whatever features we want, but we recommend starting with super small optimizations to make sure that our users are at least finding success in a small way on day one.
We'll share some examples below and break them out by daily, weekly, and monthly product practices.
Common daily practices to build a moat:
Review 1 piece of customer feedback
Fix 1 minor bug
Simplify 1 line of onboarding copy
Reduce load time by 1 millisecond
Ensure the core feature works flawlessly
Send a welcome email to a new user
Test the sign-up flow ourselves
Notice that most items on this list can be completed quickly. Make your product improvements so consistent that you can stick to them even on the hard days.
For something to become truly defensible, we need to improve it frequently. As a result, most product work is daily. But it can also be helpful to use a weekly or monthly routine. These larger updates won't be as frequent as fixing a typo, but they remind our customers that the product is alive and growing.
Common weekly practices:
Release a minor feature update
Highlight a successful user in a newsletter
Analyze drop-off points in the user journey
Interview one power user
Clean up technical debt
Monthly practices:
Launch a major integration
Publish a roadmap update
Host a community webinar
Review competitor vulnerabilities
Finally, we can build a moat by carefully choosing what we don't build. We call these "features of avoidance" (that is, bloated features we are trying to avoid).
Features of avoidance:
No features that don't serve the core mission
No confusing pricing tiers
No mandatory long-term contracts
No hidden cancellation buttons
No dark patterns in the UI
Case Studies: 3 Products with Powerful Moats
Despite all of the theory, a product moat is easiest to understand when we look at the real world. Let's look at three successful, well-known software products that turned their platforms into unbreakable fortresses.
Case Study #1: Slack (The Integration Moat)
When Slack first launched, it was just a simple chat room for businesses. It was easy to use, but chat rooms had existed for decades. So how did Slack build a moat? They did it through integrations.
Slack made it incredibly easy to connect other tools. Soon, teams were plugging in their Google Drives, their Trello boards, their GitHub repositories, and their customer support tickets.
The Moat: High switching costs. If a company wants to leave Slack today, they aren't just leaving a chat app. They are ripping out the central nervous system of their entire operation. To switch to a competitor means reconnecting dozens of apps and retraining the entire company. Slack's product became a moat because it became the hub for everything else.
Case Study #2: Figma (The Network Effect Moat)
For years, designing software meant working alone on a file, saving it, and emailing it to a colleague. Then Figma arrived. Figma made design work entirely in the web browser, allowing multiple people to work on the same file at the exact same time.
The Moat: Network effects. When a designer uses Figma, they naturally invite developers, copywriters, and project managers to view the file. The product is inherently collaborative. Every time a designer shares a link, Figma acquires a new user for free. If a design agency tries to switch to an offline tool, the entire collaborative workflow breaks down. Figma’s moat is the network of people interacting inside the canvas.
Case Study #3: Notion (The Customization Moat)
Notion is a workspace tool that allows you to write documents, build databases, and organize knowledge. But when you first open it, it is essentially a blank page. You have to build your own workspace using their flexible blocks.
The Moat: Deep user investment. Because Notion requires users to build their own custom systems—trackers, wikis, content calendars—users pour hours of their own thought and architecture into the software. The longer we use Notion, the more tailored it becomes to our specific brain. The moat here is personal investment. To leave Notion is to abandon hours of personal organizing effort. The product is sticky because we made it sticky.
How Long Does It Take to Build a Moat?
One of the most common questions we get is, "How long does it take to build a competitive moat?"
You'll see all kinds of answers: a few months, a year, after your Series A funding round. Some people think it happens the moment you reach a million users. However, the reality of product development is much wider.
We find that people are really trying to get at something else when they ask this question. What they often mean is, “How long until business is easy? How long until I don't have to worry about competitors anymore?”
Look, business gets a little easier with scale. But this line of questioning ignores the real purpose of building a great product in the first place.
How long does it take to build a moat? The honest answer is: forever. Because once we stop improving the product, the moat starts to dry up.
A great product is a commitment to be lived, not a finish line to be crossed. We are looking to make small, sustainable improvements we can stick with for years. And focusing on the product is one tool in our toolbox on the road to business success. It is an effective way to visualize our value, protect our progress, and motivate our users to show up again tomorrow.
