Bet Against the Founders on Adjacent Markets
Founders' conviction is a moat against their own blind spots — the adjacent market they dismiss is often the alpha
Founders develop deep conviction about what their company is and isn't — and this conviction is simultaneously the engine of their success and the source of their largest strategic blind spots. The markets founders most aggressively dismiss are often the ones most correlated with the company's actual competitive advantage, because founders reject them for identity reasons rather than capability reasons.
Khosrowshahi's formulation: when he proposed integrating taxis into Uber, the founders (including Travis Kalanick) were strongly opposed — Uber was defined as the anti-taxi, the disruptive force replacing the legacy industry. Adding taxis felt like a category betrayal. But the actual customer behavior data showed that the distinction between 'Uber car' and 'taxi' was already blurring in markets where both existed side by side. The founder identity narrative was diverging from customer reality.
The decision rule: if the founders' objection to an adjacent market is primarily identity-based ('that's not what we are') rather than capability-based ('we can't execute that'), the market is likely worth pursuing. Identity objections are a signal that the company has the capability but not the permission — and granting that permission requires someone without the founder's identity investment.
- Founders' strongest identity-based rejections mark the boundaries of their blind spots, not the limits of the company's capability.
- Customer behavior data overrides founder narrative — if customers would use the adjacent product, the identity objection is a company problem, not a market problem.
- Incoming CEOs have unique permission to pursue founder-rejected markets because they carry no identity debt from the founding narrative.
- The fastest-growing segment is often the one the founding culture had lowest status for — taxi, not premium black car, was Uber's growth engine.
- Speed of execution on the contrarian move matters — the window where the adjacent market is undefended closes as competitors identify it.
- Map the founder-rejected market categoriesIdentify which adjacent markets or product categories the founding culture has explicitly rejected or consistently dismissed. Separate the rejections into identity-based ('that's not who we are') and capability-based ('we cannot execute that').Pro tipThe intensity of the rejection is often correlated with the size of the opportunity — founders reject things hard when they feel the pull toward them and need to resist.
- Test customer behavior vs. founder narrativeFor identity-rejected markets, test whether customers actually care about the distinction the founders draw. If customers use both your product and the 'forbidden' category without cognitive dissonance, the market boundary exists only internally.WarningIf customers do distinguish clearly between your product and the adjacent category, the founder's identity objection may be tracking a real strategic constraint. Confirm before proceeding.
- Quantify the capability overlapAssess whether the company's existing technology, distribution, and operational capabilities serve the adjacent market with minor adaptation. If the capability stack already serves the market, the only barrier is permission.Pro tipFor Uber: the driver matching, routing, payment, and app infrastructure that served black car rides also served taxi rides. The capability overlap was near-complete — the barrier was entirely narrative.
- Execute without seeking founder consensusIf the data supports the move and the objections are identity-based, execute without waiting for founder buy-in. Founder consensus on their own blind spots is not achievable — it requires them to invalidate their founding narrative, which they will not do voluntarily.Pro tipMove fast. The window where the adjacent market is undefended is narrow. Competitors who don't carry the identity debt will see it too.WarningThis step requires clear authority. Only available to CEOs or operators with decision rights over the relevant resource allocation.
- Let the results validate the decisionAfter execution, track the adjacent market's growth rate relative to core business. If the framework is right, the adjacent market becomes a top growth driver within 12-24 months — using this data to update the organizational narrative makes the decision durable.
Uber's founding narrative was explicitly anti-taxi — the disruption of a legacy, low-quality service. Adding taxi partners to the Uber platform felt like a category betrayal to the founders. Khosrowshahi overrode this, integrating taxi fleets into the Uber app. The founders thought he was 'absolutely out of his mind.'
At IAC and Expedia, the instinct was to build digital-native travel products. Acquiring Hotels.com — a telephone-first travel booking company in transition — felt like buying the past. The identity objection: 'we are digital, that is legacy.' The capability reality: Hotels.com's inventory and supplier relationships were exactly what a digital platform needed.
Khosrowshahi encountered this directly in his first year as Uber CEO. The taxi integration decision was not a close call strategically — the data supported it. But the organizational and reputational risk of overriding Uber's founder-defined identity was significant. The founders had staked their reputations on the narrative of Uber as the taxi-killer. Adding taxis meant partially invalidating that narrative. Khosrowshahi's read: the narrative was about the founders' identity, not about Uber's optimal strategy. He proceeded with the integration. The taxi segment became Uber's fastest-growing business.
