Crossing the Chasm

Marketing and Selling Disruptive Products to Mainstream Customers

Geoffrey A. Moore · 1991 · HarperBusiness

The classic explanation of why early enthusiasm stalls before mainstream adoption, and a focused plan to get past it.

The big idea

What the book argues

Moore argues that technology markets don't grow smoothly. Early adopters, whom he calls visionaries, buy because a new product promises a leap ahead, and they tolerate rough edges. The early majority, the pragmatists, buy only proven, complete solutions that their peers already use. Between the two sits a gap where many companies stall. The way across is to concentrate on one narrow segment, deliver everything it needs, become its leading vendor, and expand from there.

Key takeaways

7 ideas worth keeping

1

Early adopters and the mainstream buy for different reasons

Moore's adoption life cycle runs from innovators and early adopters through the early majority, late majority, and laggards. Visionaries want a breakthrough and accept risk; pragmatists want incremental, reliable gains and references from people like them. A pitch that excites visionaries about revolution can make pragmatists nervous. Selling to one with the other's playbook stalls growth.

Illustration: A startup wins ten enthusiastic early customers, then finds mainstream buyers keep asking who else in their industry uses it.
2

Win one beachhead before you expand

Moore uses the D-Day invasion as his analogy: concentrate all your force on one narrow target segment you can dominate, rather than landing along the whole coast. Leadership in a small market makes you the safe choice there, produces references, and gives you a base to move into adjacent segments, which he likens to knocking down bowling pins.

Illustration: Moore describes Documentum focusing first on regulatory-affairs departments at a small set of large pharmaceutical companies before expanding.
3

Choose the segment with a compelling reason to buy

Reliable market data is scarce at this stage, so Moore relies on informed judgment. Write concrete scenarios of target customers before and after adopting your product, then score them on factors such as whether they have an urgent reason to buy, whether you can deliver a complete solution, and how strong the competition is. Favor buyers whose current process is badly broken.

4

Sell the whole product, not just the core

Pragmatists need a complete solution: the core product plus integrations, training, support, services, and complementary products that make it work in their environment. Map what your target customer needs to realize the benefit and fill the gaps yourself or through partners. A complete solution built on decent technology can beat superior technology delivered incomplete.

5

Position the product with a two-sentence statement

Moore offers a template: for a specific target customer who has a compelling need, the product is a particular kind of offering that delivers a key benefit; unlike the main alternative, it provides a clear point of difference. If you can't fill it in cleanly, you probably haven't chosen your segment yet.

Illustration: For field-service managers at mid-size HVAC firms who lose jobs to missed callbacks, our product is a scheduling system that confirms every appointment automatically. Unlike spreadsheets and paper, it alerts dispatchers before a customer is dropped.
6

Define your competition deliberately, even create it

Pragmatists want a frame of reference and an existing budget. Moore suggests naming a market alternative, the established option whose budget you will capture, and a product alternative, another newer offering that shows the category is real. Then position against both. Claiming no competition tells pragmatists the market is immature and risky.

7

Plan distribution and spending for the niche

Moore's final steps cover how to reach and price for the beachhead. Complex, high-consideration purchases often require direct sales early on, and pricing should reflect the value relative to the market leader rather than cost. Revenue during the crossing tends to be uneven, so size spending and hiring to the segment, not to hockey-stick forecasts.

The framework

Moore's D-Day plan for crossing the chasm

01

Target the point of attack

Pick one narrow segment with a compelling reason to buy that you can dominate.

02

Assemble the invasion force

Build the whole product the segment needs, using partners to fill gaps.

03

Define the battle

Name market and product alternatives and position against them.

04

Launch the invasion

Choose the distribution channel and pricing that fit the segment.

05

Expand pin by pin

Use the beachhead's references to move into adjacent segments.

Three moves to make now

  1. Write customer scenarios for three candidate segments and score each on urgency to buy, your ability to deliver a complete solution, and competition.
  2. Fill in Moore's two-sentence positioning statement for your chosen segment and test it on five prospective customers.
  3. List everything a customer needs beyond your core product to get the full benefit, and decide which gaps you will fill and which partners will fill.
