Is it realistic to make organizations that stay on mission long after the founder is gone?

I listened to a podcast interview you did where you talked positively about the Novo Nordisk Foundation as a successful governance story, but when I think of long lived foundations, I think of the Ford Foundation and the Hewlet Foundation that have significantly drifted from the founders' visions despite being non-profits. Many people think it is better for foundations to spend down all their resources before the founder is gone to prevent this drift and loss of efficacy.

Have you done any studies of what made long lived foundations drift on their mission despite no profit incentive?

I'm not an academic, so no, I have not done any of these studies, but good news, everyone: other people have. The specific structure of Nova Nordisk is not just a foundation. I think the two-entity structure, where a foundation oversees or governs a for-profit company, is uniquely suited to longevity of a mission precisely because it combines the stewardship orientation of the foundation with the performance orientation of the for-profit subsidiary. The data shows (for what it's worth) that such structures are five or six times more likely to live to year 50 compared to a standard for-profit company. I give examples in the book also of pure foundations that have lost this structure or have lost their mission integrity too. I really think you need both for it to endure.

Do you have any thoughts on Mozilla? It has a two-entity structure, but there are a lot of complaints that it is not sticking to its mission (or, slightly differently, that it's not succeeding at it, due to poor strategic choices).
