Wow really I had no idea. This rabbit hole goes deeper then I expected!
In 2022, the project evolved into a commercial entity called Pydantic Services Inc., founded by Samuel Colvin and Adrian Garcia Badaracco, to build products around the open-source library. The company raised $4.7 million in seed funding in February 2023, led by Sequoia Capital, with participation from Partech, Irregular Expressions, and other investors. This was followed by a $12.5 million Series A round in October 2024, again led by Sequoia Capital and including Partech Partners, bringing the total funding to approximately $17.2 million across rounds. The Series A funding coincided with the launch of Pydantic Logfire, a commercial observability platform for backend applications, aimed at expanding beyond the core open-source validation framework. As of mid-2025, no additional funding rounds have been publicly reported.
Pydantic (the company) owns logfire, a logging service. There’s a lot of money in logging/observability. The pydantic library itself is not monetizable, as you indicate.
