[AINews] New AI Infra unicorns: Exa, Modal, TurboPuffer

Latent Space summarized AI News for May 20-21, 2026, confirming TurboPuffer reached $100 million ARR and profitability, Exa raised a $250 million Series C at a $2.2 billion valuation, and Modal raised a $355 million Series C at a $4.7 billion valuation.
