The Case for the Deliberate Generalist
Range, done deliberately, is its own form of expertise — not a placeholder for someone who couldn't pick a lane.
When a company, fund, or institution steps into unfamiliar territory — a new vertical, a technology outside its usual playbook, a market none of its leaders have operated in — the instinct is almost always to hire a specialist in that specific field. Sometimes that's right. But there's another profile worth having in the room, one that rarely gets asked for by name because it doesn't have a clean job title: the advisor who has done this — genuinely, credibly, repeatedly — across domains that share nothing on the surface.
I've built my career as that profile. A locomotive fuel-optimization system now based in Tel Aviv. A cardiac pre-diagnosis app out of a redeveloped incubator in Perm', Russia. An athlete-and-event platform in Philadelphia. Extreme-sports engineering in Southern California. Training venture capitalists across Siberia on how to evaluate deals. None of these came out of a single technical background. Each one came from the same underlying skill: learning a domain's economics, constraints, and vocabulary fast enough to be useful in it — not eventually, immediately.
That skill rarely gets named directly, and I think that's a mistake. We have a well-developed language for depth — “10,000 hours,” “specialist,” “domain expert.” We don't have an equally serious vocabulary for the discipline of rapid, credible domain acquisition. It gets called “adaptability” or “being a fast learner,” language that makes it sound passive, almost accidental. In practice, it's a repeatable method, and it's the one I bring into every new engagement:
Find the actual constraint, not the interesting one.
Every new domain has a flashy technical story and a boring economic one. The boring one is usually what matters. A sensor network is interesting. “$20 million a day in downtime” is what gets a deal signed.
Borrow structure before you borrow expertise.
I don't need to become a metallurgist to advise a materials-science venture. I need to know what questions metallurgists argue about, and why. Structure transfers faster than knowledge does.
Find the person who'll tell you what you don't know you don't know.
Every domain has a “stump the expert” moment waiting for an outsider, and the goal is to fail that test in private, with someone patient, long before it costs a client the room.
Treat the track record as the credential.
A generalist without evidence is just unfocused. A generalist with a decade of receipts — ventures advised, capital raised, deals structured, across genuinely different verticals — offers something a single-domain specialist can't: proof that the method itself works, independent of any one field.
None of this is an argument against specialists. Deep domain expertise is irreplaceable, and I've spent plenty of my career deferring to it. It's an argument that going wide, done deliberately, is its own form of expertise — not a placeholder for someone who couldn't pick a lane.
The organizations that need this most are the ones standing at the edge of an unfamiliar domain for the first time: a company evaluating a new vertical, a fund looking at a sector its partners don't know, a university trying to commercialize a technology outside its usual playbook. In those moments, the person who's done this before — who has a method, not just enthusiasm — is worth more than another specialist in the field its leaders already understand.
Depth is a destination. Range, done well, is a discipline.
It's time we treated it like one.
