A portfolio model that resists the trap of chasing profitability at the expense of new growth, or chasing growth on a shaky core. The core product sits at the center; you obsess over making it as flawless and efficient as possible. Only when the core is genuinely well-tended do you earn the 'license' to expand outward into growth bets. The economics reinforce it: tiny efficiencies on an enormous core (33 million trips/day) compound massively.
Origin
Sachin Kansal's framework for balancing Uber's post-Covid profitability drive against continued new-growth bets, so cost-cutting doesn't kill the future.
Core principles
- 01The core is where multi-point failure must be driven to near-zero — obsess over flawlessness and efficiency
- 02On a huge core, even one cent of efficiency per transaction compounds enormously
- 03Tending the core earns the license to expand into new concentric rings
- 04Growth bets (Eats, groceries, Reserve, Teens) historically emerge from a well-run core
How to run it
- 1
Define and map the core's failure points
Identify the core product and every multi-point failure possibility in it — from opening the app through driver acceptance, pickup, drop-off, and receipt. Map each step on both sides of the marketplace.
- 2
Obsess over core flawlessness and efficiency
Pour attention into making the core as flawless and as efficient as possible. Dog-food the core specifically, because that's where scale makes every improvement matter most.
Pro tip Quantify the leverage: a 1-cent efficiency gain across 33 million daily trips makes the numbers 'really start to add up.'
Watch out A distracted core at scale leaks value on every single transaction, multiplied by millions.

Earn and then spend the license to expand
Once the core is genuinely well-tended, treat that as a license to move outward into new growth bets in the surrounding rings.
Pro tip Frame new bets as concentric expansion from a healthy core, not as bets funded by neglecting it.
Watch out Chasing profitability or growth while the core is under-attended forfeits the foundation the expansion depends on.
In the wild
Because Uber kept obsessing over its core rides/delivery marketplace, it earned the room to launch outward rings: Uber Eats, Uber groceries, Uber Reserve, and Uber for Teens — now collectively growth bets in the billions of dollars.
→ Multiple multi-billion-dollar businesses emerged as concentric expansions from a well-tended core.
When Covid dropped Uber's mobility business 80% overnight, leadership divested the self-driving unit and Uber Elevate — hard calls to keep the company solvent while preserving capacity for future growth bets.
→ Uber became profitable ~2 years later and kept making bets outside the core, showing efficiency and growth can coexist.
Common mistakes
Pursuing profitability while losing sight of growth bets
Kansal warns you can be so focused on driving profitability that you lose sight of new growth bets; the concentric model exists precisely to keep both alive at once.
Making outer-ring bets on a neglected core
Expanding before the core is flawless spends a license you haven't earned — the core's per-transaction leaks and failures undermine everything built on top of it.
Is it for you?
Best for
Leaders at scaled companies balancing efficiency/profitability pressure against the need to keep funding new growth bets
Not ideal for
Pre-product-market-fit startups with no established core to defend or compound
From the transcript
“I think of our portfolio as concentric circles.”
“And we obsess over making sure that that core is as flawless as possible.”
“So imagine taking even 1 cent of efficiency out of 33 million trips every day. It just the numbers just really start to add up.”
“then you get the license to expand out of that core and start to think about other growth bets”
