Six problems hiding in plain sight

Not trends. Not features. Structural, expensive, unglamorous problems that whole industries have learned to live with — and that the next generation of great companies will be built on.

  • The succession cliff

    Millions of profitable small businesses are owned by founders nearing retirement with no buyer lined up. A generation of value is set to evaporate — and no one has built the rails to transfer it.

  • The trades are vanishing

    Electricians, machinists, and welders are retiring faster than they're replaced. The physical economy runs on them — yet hiring, training, and matching them to work still happens on paper and phone calls.

  • Healthcare's paperwork tax

    Roughly a third of every healthcare dollar disappears into billing, coding, and prior-authorization friction. Patients wait, clinicians burn out, and the back office still runs on fax machines.

  • Construction never got faster

    Almost every industry has multiplied its output per worker since 1970. Construction hasn't. Projects run late and over budget by default, and the tools haven't caught up to the stakes.

  • Who cares for the old?

    The over-80 population is doubling while the caregiver workforce shrinks. Families are left to coordinate care by spreadsheet, and the systems meant to help are fragmented and overwhelmed.

  • The uninsurable world

    As climate volatility rises, whole regions and industries are becoming too risky to insure. Pricing, modeling, and covering 21st-century risk is a problem the 20th-century insurance stack can't solve.

The thesis

Why the biggest problems stay open

If these problems are so valuable, why are they still here? The same three reasons that scare everyone else off are exactly why they're worth your decade.

  1. They're unglamorous

    Talent chases shiny consumer apps. The trillion-dollar problems hide inside unsexy industries — billing, logistics, trades, eldercare — that everyone scrolls past. Attention is the first moat.

  2. They're genuinely hard

    Real problems sit behind regulation, entrenched incumbents, and physical-world complexity. That difficulty filters out the tourists — and leaves the field open for the few willing to do the hard part.

  3. They're mispriced

    When everyone avoids a problem, the one team that cracks it inherits the entire market. Difficulty isn't the obstacle to the opportunity. Difficulty is the opportunity.
