Think It, Build It, Ship It, Tweak It
Four product phases where spend rises stage by stage — so you must retire risk before the money starts.

A simple four-phase model for where a product is in its life and how much you should be spending at each: think it (cheap, exploratory), build it (expensive), ship it, tweak it. The key discipline is that build-it costs spike, so you must have reduced the risk during the cheap think-it phase before you commit real money.
Origin
Coined off-the-cuff by Söderström at Spotify roughly 12 years earlier; it 'stuck' and is now echoed even at other companies.
Core principles
- 01Every product sits in exactly one of four phases
- 02Cost is near-zero in think it and spikes in build it
- 03You must retire risk while it's still cheap, before build it
- 04A catchy, sticky label spreads and aligns teams almost for free
How to run it
- 1
Think it — cheaply reduce risk
Explore the idea while spending little money. The whole purpose is to increase your confidence that you're right before the expensive phase begins.
Pro tip Treat think-it as risk-reduction, not just ideation — its job is to earn the right to spend in build-it.
Watch out Skipping real risk-reduction here means you carry your uncertainty into the phase where mistakes get expensive.
- 2
Build it — spend only after risk is reduced
This is where money starts flowing heavily, so only enter it once think-it has meaningfully de-risked the bet.
Watch out Entering build-it with unresolved fundamental risk burns large budgets on ideas that should have died cheaply.
- 3
Ship it — release
Put the product in front of real users once it has been built.
- 4
Tweak it — iterate on the live product
Refine and optimize based on real usage after launch.
Pro tip A shared phase vocabulary lets anyone say 'we're still in think-it' and instantly align on how much to spend and how much certainty is required.
In the wild
Söderström invented 'think it, build it, ship it, tweak it' off the cuff ~12 years ago just because teams needed a definition of product phases. He admits it 'wasn't that thought through.'
→ It stuck and spread; he still hears it, sometimes even from other companies referring to which phase they're in.
Common mistakes
Spending build-it money before think-it de-risks the idea
Because cost spikes in build it, entering it with unresolved risk means large budgets get committed to bets that should have been killed while they were still cheap.
Treating think-it as mere brainstorming
If the cheap phase doesn't actively reduce risk, it fails its real job and the uncertainty simply carries into the expensive phase.
Is it for you?
Best for
Product teams that need a shared, memorable vocabulary to gate spending against risk across a product's life.
Not ideal for
Contexts demanding rigorous stage-gate governance, where a catchy four-word model is too coarse.
From the transcript
“it's uh think it, build it, ship it, tweak it.”
“In the build it phase, you're going to start spending a lot of money. So, then you must have reduced the risk in the think…”
“it's funny because I still hear it, sometimes even from other companies.”
