What happened
Ineffable Intelligence raised $1.1 billion in seed funding on April 27, 2026. Founder David Silver was a senior researcher at Google DeepMind, where he helped lead the AlphaGo and AlphaZero work. The new company is based in London. Sequoia Capital and Lightspeed Venture Partners led the round. NVIDIA joined as a strategic backer.
Why it matters
The round is one of the largest seed rounds on record for any tech company. The post money valuation is $5.1 billion at the seed stage. The startup says its long-term goal is superintelligence research. The size of the check shows that top investors are still willing to make multi-billion-dollar bets on new frontier labs.
MintedBrain take
For MintedBrain users, the practical takeaway is that the frontier model field keeps expanding. New labs may bring new tools and APIs that compete with OpenAI, Anthropic, and Google over the next two years.
