The Impactist Manifesto
Every age has a measure. The founding text of Impactism — the case for making impact, not money, the measure of a life.
A Culture Worth the Wealth
A century-forward vision: markets still run and no one goes without — what changes is what a culture chooses to honor.
Let's leave less to fix — and more to build on.
Whether you're a founder building toward that, an organizer planning a stage, or a journalist working on a story — I'd like to hear from you.
