​Samuel Colvin​ - the creator of ​Pydantic​ - the most popular data validation library for Python. Used by literally everyone (Anthropic, OpenAI, Meta, NVIDIA, even the NSA). He shares the story behind his startup ​Logfire​ which just raised $12.5m from Sequoia.

This episode is brought to you by WorkOS. If you're thinking about selling to enterprise customers, WorkOS can help you add enterprise features like Single Sign On and audit logs.

Key takeaways:
- You can just build a different product to your open source project and leverage your brand
- Quality of product matters a LOT (if you can build a popular open source project, can probably build a quality paid product)
- Really helps to be part of a movement. Hard to predict but Pydantic benefited from two (types and LLMs)
- GitHub stars are a vanity metric compared to download numbers
