Reflection AI, a Brooklyn-based artificial intelligence developer founded by former Google DeepMind researchers, has raised US$2 billion in new funding, lifting its valuation to US$8 billion. The deal stands among the largest private financings in the AI sector in 2025 and marks a swift rise from its March 2025 round, when the company secured US$130 million at a US$545 million valuation.
Funding Details
The latest round was led by Nvidia, reinforcing the critical role of specialised chips in training large-scale AI models. The syndicate includes Disruptive, DST Global, 1789 Capital, B Capital, Lightspeed Venture Partners, Sequoia Capital, CRV (Charles River Ventures), Citigroup, Singapore’s GIC, Eric Yuan, and Eric Schmidt — a group reflecting both institutional depth and strategic industry interest.
Reflection AI plans to allocate much of the funding toward expanding compute resources to train its first frontier-scale open-weights model, which is expected in early 2026. The company’s training pipeline integrates large-scale reinforcement learning techniques with mixture-of-experts (MoE) architectures designed for efficiency at frontier model sizes.
Company Background and Technical Focus
Reflection AI was founded in 2024 by Misha Laskin, who previously led reward modelling for DeepMind’s Gemini project, and Ioannis Antonoglou, a core researcher on the AlphaGo system. The company initially focused on autonomous coding agents capable of parsing complex codebases, generating code, debugging, and automating engineering workflows.
In July 2025, Reflection AI launched Asimov, an autonomous coding agent that analyses source code alongside contextual documentation such as design notes, internal messages, and technical discussions. Asimov was positioned as a deeper reasoning system for software engineering teams.
Later in 2025, Reflection AI broadened its mission, outlining plans to build open-weights frontier models using a custom reinforcement learning platform capable of training at scales comparable to major AI labs. This shift expanded the company’s trajectory from developer tooling to general-purpose AI research.
Strategic Positioning
Reflection AI presents itself as a Western open-weights alternative to proprietary frontier AI developers such as OpenAI and Anthropic, while also positioning as a U.S.-based counterpart to China’s DeepSeek, which has seen rapid global uptake for efficient open-weight models.
The company intends to publicly release its model weights, allowing external researchers and developers to examine, adapt, and build on its systems. At the same time, Reflection AI will maintain proprietary control over its data pipelines, compute environment, and optimisation infrastructure. This approach aims to combine transparency with operational security.
Market Context and Competitive Landscape
The funding arrives during a strong period for global venture investment. Worldwide VC flows reached US$97 billion in Q3 2025, with AI accounting for approximately 46% of total investment activity.
Reflection AI’s valuation trajectory, from US$545 million to US$8 billion in seven months, parallels the broader surge in companies developing autonomous and agentic AI systems. Comparable players include:
Cognition Labs, creator of the Devin autonomous software engineer, which rose from a US$4 billion valuation in early 2025 to over US$10 billion later in the year.
Anysphere, developer of the Cursor coding platform, which rapidly expanded and reached a valuation of about US$29 billion in late 2025.
While Cognition and Anysphere remain centred around next-generation developer tools, Reflection AI is targeting general-purpose frontier models, positioning itself as a broader AI platform rather than a product-specific provider.
Future Outlook
Industry analysts note that Reflection AI’s long-term prospects will depend on its ability to deliver high-performance open-weights models that can attract both enterprise adoption and community-driven research. Sustained access to compute, recruitment of specialised talent, and commercial partnerships will also shape the company’s trajectory.
Nvidia’s participation underscores a broader industry realignment toward ecosystems built around advanced AI hardware. Reflection AI currently employs around 60 researchers and engineers, many with backgrounds from DeepMind, OpenAI, and Anthropic, and expects significant team expansion as it moves into frontier-scale training.
