The company develops techniques to inspect how AI models represent concepts internally, modify behaviors, and extract insights, positioning itself as a 'neolab' focused on breakthroughs in training and model understanding deprioritized by scaling labs. Goodfire's team includes experts from OpenAI, Google DeepMind, and top universities, with co-founders Eric Ho, Daniel Balsam, and Tom McGrath. In February 2026, Goodfire raised $150 million in a Series B round at a $1.25 billion valuation, led by B Capital, with participation from Juniper Ventures, Menlo Ventures, Lightspeed Venture Partners, South Park Commons, Wing Venture Capital, DFJ Growth, Salesforce Ventures, Eric Schmidt, and others. This brings total funding to over $200 million since founding in 2024, following a Series A less than a year prior. Proceeds will advance frontier AI research, develop a model design environment platform for scaled understanding and intervention in AI models, enhance computing power, hire staff, and expand partnerships in AI agents and life sciences. Goodfire partners with Microsoft, Mayo Clinic, Arc Institute, and Prima Mente, applying interpretability to reduce LLM hallucinations by half, identify novel Alzheimer's biomarkers from reverse-engineering models, and support scientific discovery. The company emphasizes selective, deep engagements with high-stakes AI builders, using interpretability for digital biology and model-to-human knowledge transfer, as demonstrated in extracting chess concepts from AlphaZero.
