The world's hardest problems are also its biggest opportunities.
Most people see crises; climate, energy, broken systems, geopolitical instability; and look away.
Some see the most important work of their generation.
The next economy will be built by the founders who chose the hard problems, and the funders who had the conviction to back them early.
Impact/Week 2026. Let’s build what matters.
