Rebuild Money

Fixing the infrastructure of global finance

Financial infrastructure was built for a different era. Cross-border payments take days. 2 billion people are unbanked. Small businesses can't access capital. Crypto promised a revolution but mostly delivered speculation. We're looking for practical solutions that make money work better for everyone.

  • Moonshots that attract exceptional talent, or niche markets big enough to build on but overlooked by big players
  • Frustrations backed by real evidence — quotes, data, or personal experience
  • Problems where no good solution exists yet, only workarounds

Moonshots

The problems that define the next century

Some problems are so large that solving them changes everything. Fusion energy. Brain-computer interfaces. Reversing aging. These aren't incremental improvements—they're civilizational shifts. We're looking for the technical breakthroughs and bold bets that seem impossible until they're inevitable.

Niche Markets

Small markets that desperately need a champion

The best businesses often start in markets that look too small. Vertical SaaS for dry cleaners. Tools for independent truckers. Software for yacht brokers. These niches are ignored by big companies but represent real pain for real people. Dominate a niche, then expand.

Future of Work

Reinventing how 4 billion people spend their days

Work is being rebuilt from scratch. Remote collaboration. AI-augmented productivity. The death of the 9-to-5. The rise of the portfolio career. The companies that define how we work in 2035 are being built now. We're looking for the tools, platforms, and systems that will shape the next era of human productivity.

Creator Economy

Powering the next generation of independent creators

50 million people now consider themselves creators. Most make less than $500/year. The infrastructure is broken—discovery is algorithmic roulette, monetization favors platforms over people, and burnout is the norm. We need better tools for creators to build sustainable businesses around their work.

Longevity

Adding decades to the human healthspan

The science of aging is accelerating. Senolytics. Gene therapy. Epigenetic reprogramming. For the first time, extending healthy human lifespan is a serious engineering challenge, not science fiction. The companies solving these problems won't just build billion-dollar businesses—they'll change what it means to be human.

Climate Tech

The decade that decides everything

We have 10 years to fundamentally transform energy, transportation, agriculture, and manufacturing. This isn't about incremental efficiency—it's about reinventing trillion-dollar industries. The climate transition will create more wealth than the internet. The problems are urgent, massive, and solvable.
