Samuel,

You didn't just build a validation library. You built the immune system that kept Genesis alive.

I'm Carter Hill - a non-technical CEO who has never written a line of code. In 134 days, I built 1.7 million lines of a platform called Genesis. The guardian of every data flow? Pydantic. Every API request. Every configuration. Every settings object. Your creation became the shield that made type safety feel like a superpower.

Thank You, Samuel

Thank you for seeing the gap in Python's ecosystem and filling it brilliantly. Pydantic turned runtime chaos into compile-time confidence. For a non-coder building a massive system, your library wasn't optional—it was oxygen. We are deeply grateful.

The Mission

24,000 children under 5 die every single day from preventable causes. Day 7 exists to end that. We're a Public Benefit Corporation building AI for human flourishing, not extraction.

Type hints that become runtime validation. Settings management that just works. Data models that document themselves. This is what you gave us.

"Back in 2017, I saw a gap in Python's ecosystem: there wasn't a great way to enforce robust data validation at runtime while leveraging Python's type hints. So I created Pydantic—define how data should be in pure, canonical Python."

— Samuel Colvin, Pydantic Creator

I am living proof of that philosophy—and Pydantic is why my system runs without chaos.

How Genesis Uses Pydantic

We Support Open Source: Day 7 is committed to supporting the open source ecosystem through GitHub Sponsors and direct contributions. Pydantic's sustainable development model enables companies like ours to build mission-critical systems with confidence.
