The one number
Meet your KIN — your family's Independence Number
Every family has a number: the amount of wealth that makes work optional and freedom permanent. The wealthiest families build their whole lives around it. Most families never calculate it — the Challenge begins by finding yours.
Built on endowment math. KIN uses the same approach universities use to fund themselves in perpetuity: your family spends only what the portfolio earns above inflation, so the principal is never touched — it passes intact to the next generation.

How it works
Thirty days. One family. One working system.
You don't need to be wealthy to start — you need a plan and a few people who share your last name or your loyalty. Each week builds one layer of your family office, together.

Constitution
Agree on how your family decides, votes, and stays accountable.

Action

What you'll build
A real family office — not a folder of good intentions
Everything below leaves the Challenge finished and in use. Together, these pieces form your Family Wealth System™ — the financial operating system your family runs on long after day 30.
Your north star
One question guides every family decision
Once your family knows its number, every purchase, opportunity, and investment passes through that one filter. It turns money arguments into money decisions.

Honest about risk
Investing involves risk, including the possible loss of principal. Good Stewards is coordination software for self-directed family investment clubs — not an investment adviser or broker — and we never hold or direct your family's funds. Every investment decision is proposed, voted on, and made by your family. The $99 graduation contribution is a one-time contribution made when your family completes the Challenge; it is not a return, a guarantee, or investment advice. Your KIN is a planning guide, not a forecast — your results depend on your family's saving, spending, and the markets.
