Crossing the Chasm by Geoffrey A. Moore, first published by HarperBusiness in 1991, is a marketing book about the most dangerous stage in the life of a technology company: the move from early enthusiasts to mainstream buyers. Moore was a consultant to Silicon Valley firms, and his book gave the industry a name for a problem many founders had felt without being able to describe. A revised edition followed in 1999 and a third edition in 2014.
What is Crossing the Chasm about?
Moore builds on the technology adoption life cycle, a bell curve that splits buyers into groups: innovators, early adopters, early majority, late majority and laggards. The usual view treated the curve as smooth. Moore argues that there is a deep gap between early adopters and the early majority, because the two groups buy for opposite reasons.
Early adopters, whom he calls visionaries, want a leap ahead of competitors and will tolerate bugs and gaps to get it. The early majority, the pragmatists, want a safe improvement that works out of the box, and they buy from vendors that other pragmatists already trust. So the references and story that won the visionaries mean nothing to the pragmatists. Many startups fall into the chasm here, with promising early revenue that suddenly dries up.
The way across, in Moore’s telling, borrows from the Allied landings in Normandy. Pick one narrow segment where your product solves a painful problem, deliver the whole product that segment needs (with partners if necessary), dominate it and then use it as a beachhead to move into neighbouring segments. The rest of the book covers choosing the target, building the whole product, positioning against competitors and setting prices and distribution that fit mainstream buyers.
What are the main lessons for founders?
- Expect the stall. If deals slow after a strong start, you have likely run out of visionaries. The fix is a new story aimed at pragmatists, backed by references they trust.
- Go narrow on purpose. A niche you can win completely is better than a big market where you are one of ten options. Word of mouth inside a tight segment gives you references.
- Sell the whole product. Pragmatists need training, setup, connections to the tools they already use and support. If your startup cannot provide them, find partners who can.
- Create a competitor if you have to. Mainstream buyers need a frame of reference. Positioning yourself against a known alternative helps them understand where you fit.
- Plan the next pin. Pick segments that share needs or references with your beachhead, so each win makes the next one easier.
Who should read Crossing the Chasm?
Read it if you sell technology to businesses and are moving past your first handful of enthusiastic customers. It suits B2B software founders, deep tech and hardware startups, and sales and marketing leaders hired to take a product into the mainstream. Investors also use its vocabulary in board meetings.
Consumer app founders and companies with low-priced, self-serve products will find the enterprise-sales focus less relevant. If you have no customers at all yet, start with validation books and come back later.
How do you put Crossing the Chasm to work this week?
- Sort your current customers into visionaries and pragmatists. Note which group your last five deals came from.
- List three candidate beachhead segments and score each on how painful the problem is, how reachable the buyers are and whether you can deliver the whole product.
- Write a one-line positioning statement for your chosen segment that names the alternative you replace.

Where does Crossing the Chasm fall short?
Most examples come from enterprise software and hardware of the 1980s and 1990s, and even the third edition reads like a book from the age of field sales forces. Product-led growth, freemium models and online communities, which let some companies skip parts of the chasm, get little attention. The framework also assumes a fairly linear adoption path that not every market follows. Pair it with Obviously Awesome for a modern positioning process and The Innovator’s Dilemma for the incumbent’s side of disruption.
