Goodfire has raised $150 million in a Series B funding round, valuing the company at $1.25 billion, marking a major milestone in its mission to make advanced AI systems more transparent, controllable, and reliable.
The round was led by B Capital, with participation from Juniper Ventures, DFJ Growth, Salesforce Ventures, Menlo Ventures, Lightspeed Venture Partners, South Park Commons, Wing Venture Capital, and notable individual investor Eric Schmidt, among others.
Founded to address the growing risks of opaque, black-box AI models, Goodfire focuses on AI interpretability, a field aimed at understanding how neural networks make decisions internally. The new funding will be used to expand research, scale its interpretability platform, and deepen partnerships with organizations deploying AI in high-stakes environments.
Goodfire has already collaborated with leading research institutions and industry partners to apply interpretability techniques in areas such as large language models and biological foundation models. The company says the Series B will accelerate its ability to move from research breakthroughs to production-ready tools.
As AI systems become more deeply embedded in software, science, and critical infrastructure, investor interest in transparency and alignment continues to grow. Goodfire’s latest funding round signals strong confidence that interpretability will play a central role in the next phase of AI development.
