UNICORN

Reflection AI is positioning itself as America's open-source frontier AI lab and a Western counter to Chinese labs like DeepSeek. Co-founded in March 2024 by Misha Laskin (led reward modeling for DeepMind's Gemini) and Ioannis Antonoglou (AlphaGo co-creator), the company originally focused on autonomous coding agents and is now training a general-purpose frontier model on tens of trillions of tokens. The team is small (~60 researchers and infra engineers) but the round size is not: Reflection raised $2B in October 2025 at an $8B post-money valuation led by Nvidia — a 15x step-up from its $545M valuation seven months earlier — and is reportedly in talks to raise another ~$2.5B at a $25B pre-money valuation.
