Fast growth makes it impossible to tell what is actually working. Known problems get deprioritized because nothing looks broken, and the business quietly accumulates structural debt — dropped demand, broken liquidity, single-channel dependency — that only becomes visible when the graph turns. Lovinsky's practice is to run the diagnosis on purpose: repeatedly ask how you'd prioritize if growth went negative right now, and use the answer as your actual priority list while the growth still holds.

Core principles
- 01Growth masks all problems — under incredible growth you have no true read on what works.
- 02A business can be growing fast while dropping most of its demand on the floor.
- 03The tenor of an organization changes completely when growth goes negative — that change of lens is the valuable thing, not the crisis.
- 04A PM who has only ever worked on things that grow is missing a core piece of judgment.
How to run it
- 1
Assume the good numbers are hiding something
Treat healthy top-line growth as a reason for suspicion, not comfort. At Thumbtack triple-digit growth coexisted with the business burning through demand — dropping huge volumes of it on the floor because supply-side liquidity couldn't meet it.
Pro tip Look specifically for demand you are acquiring and failing to convert. That is the classic thing growth hides.
Watch out The team usually already knows about the problem. What growth removes is not the knowledge, it's the urgency.

Run the rehearsal question
Ask, out loud and regularly: 'What would I do right now if growth went negative? How would I prioritize things if it went negative?' Answer as if the crisis were real.
Pro tip Do this as a standing item in growth reviews, not as a one-off offsite exercise — the paranoia has to be habitual to be useful.

Reprice urgency using the crisis answer
The items that jump to the top under the negative-growth lens are your real structural risks. Fund them now, while you still have the growth, rather than when you are rebuilding the engine mid-flight.
Pro tip The crisis lens tends to surface the same categories every time: channel concentration, unconverted demand, unit economics, and a core experience that has outgrown its scrappy original design.
Watch out Rebuilding the monetization model and the product simultaneously under negative growth — changing the engine while the plane is flying — is the alternative, and it is far more expensive.

Get the scar tissue deliberately
Seek out at least one experience of turning around a business in decline. Lovinsky argues a PM who has never felt the other side of growth loses a lot in their career — the naturally paranoid lens it produces is not obtainable from reading about it.
Pro tip Also useful: the disruptor lens Lenny Rachitsky used at Airbnb — ask what a competitor entering your space today would build, then go build it before they exist.
In the wild
During its triple-digit growth years, Thumbtack was acquiring demand it could not serve — insufficient supply-side liquidity meant much of that demand was simply dropped. The team knew, but it was never urgent, because from the outside everything was going great.
→ When Google's SEO changes pushed growth to double digits and then negative for the first time in company history, the organization's tenor changed and the real issues finally became visible and fundable.
Lenny Rachitsky describes leading Airbnb's shift from request-to-book to instant booking — the same core transition Thumbtack had to make — using the lens 'if somebody was to come into our space and disrupt us and start now, what would they do?' The answer was obviously: make it instant.
→ Airbnb made the transition before things started to fall apart, unlike Thumbtack which made the equivalent change under negative growth. Rachitsky believes Airbnb would not have made it without the shift.
Common mistakes
Reading growth as validation
'What's wrong? Everything's going great' is the exact sentence that lets structural problems compound. Growth is a fog, not a scoreboard.
Waiting for the crisis to supply the urgency
The crisis does produce clarity — but it produces it at the moment you have the fewest resources and the least room to rebuild. The rehearsal is how you buy the clarity without the price.
Rebuilding everything at once under duress
Thumbtack had to rebuild the product, change the monetization model and rebuild the growth channels simultaneously while growth was negative — changing the engine while the plane was flying. Each of those was a deferred item from the growth years.
Is it for you?
Best for
Product and growth leaders at fast-growing companies who want to find structural weaknesses while they still have the surplus to fix them.
Not ideal for
Very early-stage teams still hunting for product-market fit, where there is no growth to mask anything and the paranoia is just distraction.
