Andreessen Horowitz, Amplify Partners, and Zetta Venture Partners led a $28m seed round in Boltz.

Andreessen Horowitz, a venture capital firm, Amplify Partners, an investment firm, and Zetta Venture Partners, a venture capital firm, led a $28m seed round in Boltz, with participation from Clement Delangue, Factorial Capital, and Obvious Ventures. The lead investors backed the decision to incorporate as a PBC. The rationale is that by committing to "open science" as a legal mandate, Boltz becomes the trusted, neutral platform for the entire industry. This prevents the "walled garden" problem that has slowed down adoption for other proprietary AI biotech firms.
