Summary
Goodfire, an AI interpretability startup founded by alumni from OpenAI and Google DeepMind, announced a $50M Series A led by Menlo Ventures with participation from Anthropic and others. The company is developing Ember, a platform that decodes neural network internals to make AI systems understandable, steerable, and fixable. Early applications include collaboration with the Arc Institute to extract biological insights from the Evo 2 DNA foundation model.
Key Points
- •Goodfire raised $50M Series A less than one year after founding, backed by Menlo Ventures, Lightspeed, Anthropic, and others.
- •Their flagship platform Ember provides direct, programmable access to AI model internals, enabling users to understand and shape model behavior.
- •The company focuses on mechanistic interpretability — reverse engineering neural networks to move beyond black-box AI systems.
- •Anthropic CEO Dario Amodei endorsed the investment, calling mechanistic interpretability 'among the best bets' for responsible AI development.
- •Early collaboration with Arc Institute demonstrated practical scientific applications, extracting novel biological concepts from a DNA foundation model.

Funding from Menlo Ventures powers Goodfire's mission to decode the neurons of AI models, reshaping how they're understood and designed
SAN FRANCISCO , April 17, 2025 /PRNewswire/ -- Today, Goodfire, the leading AI interpretability research company, announced a $50 million Series A funding round led by Menlo Ventures with participation from Lightspeed Venture Partners, Anthropic, B Capital, Work-Bench, Wing, South Park Commons, and other notable investors. This funding, which comes less than one year after its founding, will support the expansion of Goodfire's research initiatives and the development of the company's flagship interpretability platform, Ember, in partnership with customers.
"AI models are notoriously nondeterministic black boxes," said Deedy Das, investor at Menlo Ventures. "Goodfire's world-class team—drawn from OpenAI and Google DeepMind—is cracking open that box to help enterprises truly understand, guide, and control their AI systems."
Despite remarkable advances in AI, even leading researchers have little idea of how neural networks truly function. This knowledge gap makes neural networks difficult to engineer, prone to unpredictable failures, and increasingly risky to deploy as these powerful systems become harder to guide and understand.
"Nobody understands the mechanisms by which AI models fail, so no one knows how to fix them," said Eric Ho , co-founder and CEO of Goodfire. "Our vision is to build tools to make neural networks easy to understand, design, and fix from the inside out. This technology is critical for building the next frontier of safe and powerful foundation models."
To solve this critical problem, Goodfire is investing significantly in mechanistic interpretability research – the relatively nascent science of reverse engineering neural networks and translating those insights into a universal, model-agnostic platform. Known as Ember, Goodfire's platform decodes the neurons inside of an AI model to give direct, programmable access to its internal thoughts. By moving beyond black-box inputs and outputs, Ember unlocks entirely new ways to apply, train, and align AI models — allowing users to discover new knowledge hidden in their model, precisely shape its behaviors, and improve its performance.
"As AI capabilities advance, our ability to understand these systems must keep pace. Our investment in Goodfire reflects our belief that mechanistic interpretability is among the best bets to help us transform black-box neural networks into understandable, steerable systems—a critical foundation for the responsible development of powerful AI," said Dario Amodei , CEO and Co-Founder of An
