Sutherland's closing advice to builders: a product must work psychologically (people want it), technologically (it does something meaningfully new) and economically (you can make money from it). Most businesses inherit a Fordist production-line mentality and run these in series — build first, market last. Because innovation is not a linear process, that sequencing wastes the chance for each constraint to reshape the others.
Origin
Sutherland's own formulation, delivered as his final piece of advice. He grounds the anti-linear argument in the pivot — Wrigley began selling soap powder in Chicago, gave away baking powder to sell it, then gave away chewing gum with the baking powder, and became a chewing gum company.
Core principles
- 01The sweet spot is where psychological, technological and economic viability all hold simultaneously.
- 02Marketing and innovation are two sides of the same coin: work out what people want and find a clever way to make it, or work out what you can make and find a clever way to make people want it — the greatest thing is to do both.
- 03We pretend the innovation process is linear because we reverse-engineer our stories backwards; the real process never is.
- 04Do not leave marketing to the last minute — a serial process gives the psychological constraint no chance to influence the product.
- 05A product that fails on first iteration can succeed when sold a different way; the pivot is a search across the three constraints, not an admission of defeat.
How to run it
- 1
State the three constraints explicitly at the outset
Before building, write down the psychological case (why a real human would want this and be comfortable owning it), the technological case (what genuinely new thing it lets them do), and the economic case (how it makes money).
Watch out If you cannot articulate the psychological case, you are relying on the product speaking for itself — and good products do not automatically succeed.
- 2
Work the three in parallel, not in series
Run product, technology and marketing thinking concurrently, letting each reshape the others, rather than handing a finished build to marketing at the end of the line.
Pro tip Sutherland's test of a serial process: is marketing the last department to see it?
Watch out The Fordist / Taylorist production-line mentality forces a linear process onto something that is inherently nonlinear.
- 3
Search both directions between want and make
Alternate between the two generative moves: find what people want and engineer it, and take what you can build and engineer the want. Do not commit to one direction.
- 4
Treat first-iteration failure as a search signal
When a product fails, diagnose which of the three constraints it failed on — psychological, technological or economic — and re-enter the search on that axis rather than abandoning the idea.
Pro tip Wrigley's chain of giveaways ended with the giveaway becoming the business. The pivot found the psychological constraint the original product missed.
Watch out Do not reverse-engineer a tidy linear narrative afterwards; it will teach you the wrong lesson for next time.
- 5
Sanity-check the story you tell yourself
Assume that when you narrate any success backwards you have post-rationalised it into a straight line. Explicitly ask what marketing, timing and luck contributed that the story has erased.
Pro tip Sutherland's blunt version: Steve Jobs was not a technologist, he was a pitchman, a brilliant salesman and a fantastic marketer.
In the wild
Wrigley started out selling soap powder in Chicago. He gave away baking powder free to sell the soap powder, realised baking powder sold better, and started selling that — then gave away chewing gum with the baking powder as a gift.
→ People liked the chewing gum far more than the baking powder, and Wrigley became a chewing gum company — a nonlinear path no serial plan would have produced.
Sutherland points out that electricity in the home required a 30-year advertising campaign, dial-up internet had to be sold to people in the late 1990s, and Edward Jenner's smallpox vaccination met unbelievable skepticism until he persuaded the British royal family to vaccinate their children.
→ In hindsight we say 'I bought it because it was a great product' — but we thought it was a great product because of the marketing. Survivorship bias hides how decisive the psychological work was.
Common mistakes
Leaving marketing to the last minute
A serial build-then-sell process means the psychological constraint never gets to change the product, which is exactly when intrinsically brilliant products fail to bite.
Assuming good products automatically succeed
Do not think that good products automatically succeed or that bad ones necessarily fail. Meta Portal TV, Google Glass, the wine box and the Japanese toilet are all cited as intrinsically excellent products that never crossed the chasm.
Post-rationalising the path into a straight line
We tell stories backwards, reverse-engineering our actions so the process looks perfectly linear and logical. Believing that narrative leads you to plan the next product as if innovation were a production line.
Is it for you?
Best for
Founders and product leaders at the start of a build, deciding when marketing and psychology enter the process.
Not ideal for
Pure research or deep-tech work at a stage where no commercial or consumer surface yet exists to reason about.
From the transcript
“try and use those three things in parallel because I think what most businesses do is they try and do things in series”
“you can either work out what people want to find out a clever way to make it or you can work out what you can…”
“do not think that good products automatically succeed or that bad ones necessarily fail”
“when products succeed we forget the extent to which marketing was actually instrumental or decisive in that success”
