Reflection Raises $2B to Launch Open Frontier AI Lab, Rivaling DeepSeek
Reflection, a startup that only rolled out three months ago, just closed a $2 billion funding round. The cash will let it shift away from its early work on autonomous coding agents and aim to become, perhaps, the United States’ main open-source AI lab. If that happens, it would sit squarely against closed-door players like OpenAI and Anthropic, and even challenge China’s open-source frontrunner DeepSeek.
The company was founded in March 2024 by former UC-Berkeley researcher Misha Laskin, and its rapid climb suggests a noticeable change in the AI battlefield. The money is earmarked for building and openly releasing large foundation models - a kind of Western counterpart to the open-source ecosystems that are already taking off elsewhere. That move sets Reflection apart from the well-funded, closed-model firms and throws it into the wider debate about whether AI will be locked behind proprietary walls or grow through shared, collaborative work.
Investors seem to think the open-source route could be a critical path forward, though it’s still unclear how the market will respond.
The company, which originally focused on autonomous coding agents, is now positioning itself as both an open-source alternative to closed frontier labs like OpenAI and Anthropic, and a Western equivalent to Chinese AI firms like DeepSeek. The startup was launched in March 2024 by Misha Laskin, who led reward modeling for DeepMind’s Gemini project, and Ioannis Antonoglou, who co-created AlphaGo, the AI system that famously beat the world champion in the board game Go in 2016. Their background developing these very advanced AI systems is central to their pitch, which is that the right AI talent can build frontier models outside established tech giants.
Along with its new round, Reflection announced that it has recruited a team of top talent from DeepMind and OpenAI, and built an advanced AI training stack that it promises will be open for all. Perhaps most importantly, Reflection says it has “identified a scalable commercial model that aligns with our open intelligence strategy.” Reflection’s team currently numbers about 60 people — mostly AI researchers and engineers across infrastructure, data training, and algorithm development, per Laskin, the company’s CEO.
Seeing $2 billion flow into Reflection feels like a pretty clear signal that venture money is moving toward a different AI playbook - open-source frontier models. The round came after the company’s valuation jumped about fifteen times in less than a year, which hints at how fierce the scramble is to set the technical and philosophical direction of next-gen AI. Closed-source outfits such as OpenAI and Anthropic have long held the spotlight, but Reflection’s shift and the cash it just raised suggest a credible alternative is emerging, one that pushes back against the proprietary model.
Positioning the startup as a Western answer to China’s DeepSeek also adds a geopolitical flavor to the open-versus-closed debate. That pressure is now on the big players and the well-funded newcomers alike to spell out what they bring to the table beyond raw performance. In the end, the victor may not be the lab with the biggest model, but the group that can build a trusted, sustainable ecosystem around it.
