A startup launches, a handful of enthusiastic customers sign up, and the first few months feel like proof. Then growth flattens. The product is the same, the team is working harder, and yet the next wave of buyers doesn't show up. Geoffrey Moore's Crossing the Chasm is the best-known explanation for that stall, and it has shaped how technology companies think about go-to-market for decades.

The idea in one sentence: the customers who buy because they love a new idea are not the customers who buy because a new idea has been proven, and the gap between them can swallow a company. This article explains the model, the strategy Moore proposes for getting across, what he built on top of it, and where it stops applying.

The idea behind the chasm

Moore's model sits on top of the technology adoption life cycle, a familiar picture of a new product spreading through a population in waves. The wave-by-wave view comes from the wider diffusion research tradition, covered in our article on diffusion of innovations. The life cycle says that different kinds of customers adopt at different times, for different reasons.

Moore's contribution was to point at a specific break in that curve. On his own book page, he describes the chasm as the market development challenge that start-ups selling disruptive innovations face as they transition from early adopters to pragmatist mainstream customers. In his conversation with Lenny Rachitsky, he puts it more compactly: the gap between success with early adopters and success with the mainstream market.

The important word is gap. The model doesn't say the mainstream is hard to reach in the way a bigger market is harder than a smaller one. It says the early market and the mainstream are different kinds of markets, and what worked in the first doesn't carry over to the second.

Why visionaries and pragmatists buy differently

The whole model turns on two buyer types.

Early adopters, sometimes called visionaries, are the first customers outside the technology enthusiasts. Moore's book page says they buy into the vision of the entrepreneur and are willing to lean in to make it a reality. They'll tolerate rough edges because they see what the product could become. They're often buying a chance at a competitive jump.

Pragmatists want something else. The same page says they want to see it proven out first, specifically in use cases that they themselves have and with customers they know and can reference. In Moore's Lenny interview, the pragmatist's needs come down to a compelling reason to buy and confidence in the technology, backed by reference customers.

Put side by side, the difference looks like this.

Early adopters (visionaries) Pragmatists (mainstream)
Buy because They believe in the vision They see it working for people like them
Tolerate Gaps, rough edges, DIY integration Very little, they expect it to just work
Want to see A bold future state Proof in their own use case
Trust The founder's story References they can call

(This table is our own summary of the two descriptions above, not a quotation.)

Here's the trap. A startup that has sold to visionaries has a roster of customers who bought on belief. Those customers don't make good references for pragmatists, because they weren't solving an ordinary problem in an ordinary way. And pragmatists, by definition, won't be the first to buy. Everyone is waiting for someone else to go first, and the company has no way to break the loop. That's the chasm.

Beyond Rogers: the life cycle groups

The adoption life cycle carries several named groups, and Moore's work uses the early adopter and pragmatist labels above. Different texts name the later groups differently, so this page sticks to the two labels that matter most for the strategy. For the original research framing, see diffusion of innovations. What matters for strategy is the break between the first buyers and the mainstream, because that's where Moore says companies fail.

The strategy: pick one niche and win it

If the mainstream wants proof from people like them, the way across is to create that proof inside one group of people at a time. Moore's book page describes the approach as a segment-focused go-to-market that targets a single, highly challenging use case in a single industry.

Read that carefully. The advice isn't "serve a broad market with a polished product." It's closer to the opposite: choose one narrow segment with a hard problem and solve it so completely that the segment adopts you as its standard. The word "challenging" matters, because a difficult use case is one where a loose, generic tool fails, and where a focused solution can win real loyalty.

In the Lenny conversation, Moore frames the selection test as a target segment that is big enough to matter, small enough to lead, and a good fit with your crown jewels. The logic is to win one segment outright before expanding into the next. If you're trying to apply this test, our page on the beachhead market goes through how to compare candidate segments, and TAM, SAM and SOM helps size them.

A hypothetical example shows the logic. Imagine a scheduling tool that has been adopted by a scattered mix of freelancers, small agencies and a few clinics. Each customer likes it, but none refer to each other, and no group feels it's the tool "for them." Now imagine the team picks dental practices, rebuilds its features around chair scheduling, insurance reminders and hygienist rotations, and sells only to dentists. A dentist evaluating it can now ask another dentist. That's the reference pragmatists want. (This is an illustration, not a real company.)

Key Facts: Crossing the Chasm

  • Moore describes the chasm as the market development challenge of moving from early adopters to pragmatist mainstream customers (source).
  • Early adopters buy into the entrepreneur's vision; pragmatists want it proven in their own use cases, with customers they can reference (source).
  • The book teaches a segment-focused go-to-market that targets a single, highly challenging use case in a single industry (source).
  • Moore's segment test: big enough to matter, small enough to lead, and a good fit with your crown jewels (source).
  • The book's topics include the compelling reason to buy, the whole product, partners and allies, aligning marketing and sales, and positioning against the incumbent (source).

The compelling reason to buy

A niche alone isn't enough. Pragmatists need a reason to act now, and Moore's book page lists "identifying the compelling reason to buy" among its core topics. In plain terms, the segment must have a pain that it already feels, urgently, and that your product addresses directly.

This is a different test from "do people like it." Visionaries buy on enthusiasm. Pragmatists buy on a problem that has a cost, with a deadline or a business consequence attached. If the best argument you can make is that your product is interesting, you haven't found the compelling reason yet.

The whole product

Pragmatists also won't buy a half-finished solution. The book page lists "building out the whole product" among the topics Moore covers. The idea behind the term is that what the customer actually experiences is the full package needed to solve their problem: the core product, plus integrations, services, training, support and partner offerings that make it work in their setting. Early adopters will assemble missing pieces themselves. Pragmatists expect the pieces to be there.

That's also why the book's topic list includes "recruiting the right partners and allies." A company rarely supplies every piece of a whole product alone, and in a narrow segment the missing pieces are often things other firms already do. Choosing a niche makes this manageable, because you only need to fill the gaps for one group of users rather than every possible customer.

Positioning, sales and marketing

The same topic list names two more tasks: aligning marketing and sales, and positioning the company versus the incumbent competition. The logic follows from the rest. Once the segment is chosen, marketing talks only to that segment in its own terms, and sales repeats the same story. Positioning against the incumbent matters because pragmatists compare. They want to know why the new option is better for their situation than the safe, established choice.

For how this connects to a wider launch plan, see our general guide to go-to-market strategy, and for how to divide a market in the first place, market segmentation.

From the chasm to the bowling alley and beyond

Crossing the chasm is one stage in a longer path, and Moore later extended the model. In the Lenny conversation he describes four playbooks: Early Market, Bowling Alley, Tornado and Main Street. He stresses that what works in one stage will likely underperform in others, and that combining playbooks can undermine success.

Here's the rough sequence, using only what the sources above support:

Stage What it's about
Early Market Selling to visionaries who buy on the vision
Bowling Alley Winning one segment, then using that success to attract neighboring segments, with references carrying the weight
Tornado Rapid, mass-market adoption once the innovation has caught on
Main Street Selling to a broadly established market

The table's one-line descriptions of Bowling Alley and Main Street are our reading of the stage names plus the Lenny interview's point about leveraging success stories as references to attract other customers. Treat them as a sketch rather than Moore's own definitions.

The Tornado is better documented. On the page for his book Inside the Tornado, Moore writes that the Tornado represents market development dynamics that are the polar opposite of the chasm: instead of skepticism and hesitation, pragmatist customers are rushing to get on the bandwagon. The book lays out three playbooks in parallel, stressing how different each is in what it demands from the go-to-market team (source).

The practical point is sequencing. A company still in the early market shouldn't run the Tornado playbook, and a company in the Tornado shouldn't keep selling the way it did to visionaries.

Why it starts with a beachhead

Summaries of the chasm strategy often borrow a military image: take one beachhead first, then widen the campaign from there. The metaphor matters less than the logic behind it. Pragmatists buy on references from peers like themselves, so a company that concentrates on one segment builds those references fastest. The beachhead market page covers how to pick that first segment.

Where the model has limits

The chasm is a useful lens, but it isn't a law. A few limits are worth keeping in mind. These are our own observations about fit, not findings from a study.

  • Its home turf is B2B technology. The model was built around disruptive technology sold to organizations, where buyers wait for references. It maps less cleanly onto products that spread through consumer word of mouth, where adoption may look more like a steady ramp than a gap.
  • Not every product has a visible chasm. Some products serve the mainstream from the start, and some never find a first wave of visionaries at all.
  • Niche focus has a cost. Committing to one segment means saying no to other demand. If you pick the wrong segment, the discipline that makes the model work also makes the mistake expensive.
  • The curve is a model, not a measurement. The life cycle describes tendencies in how people adopt. Real markets overlap, and customers don't sort neatly into labeled groups.
  • It assumes you can tell when you're stuck. Early traction and a true chasm can look alike from the inside. Checking for product-market fit first helps separate a product that doesn't yet satisfy anyone from one that satisfies a small, unrepresentative group.

None of this makes the framework wrong. It makes it a tool for a particular situation: a product that has proven itself with believers and now needs to win people who aren't.

How to use the model

If you suspect you're facing the chasm, a short checklist can help:

  1. Describe your current customers honestly. Did they buy on vision, or because they had a problem and a deadline?
  2. List the segments where your product solves a painful problem most completely.
  3. Test each against the sizing rule: big enough to matter, small enough to lead, close to your core strengths.
  4. For the chosen segment, write down what the whole product would need to include, and who could supply the missing parts.
  5. Rebuild your messaging and sales conversations around that segment alone.
  6. Track references inside the segment, because they're what the next buyers will ask for.
