Business Jul 29, 2025

Micro1, an AI data labeling startup, is finalizing its Series A funding at a $500 million valuation, with backing from 01A and LG Technology Ventures.
The company recently added former Twitter COO Adam Bain to its board, giving its leadership team a boost as it grows.

Micro1's revenue surges as it scales fast

Micro1 connects expert labelers with companies to create high-quality datasets—basically the fuel that helps train smarter AI models.
Their revenue jumped from $10 million earlier this year to over $50 million now, and they're aiming for $100 million by September.

Micro1's growth and competition

Micro1's rise got a push after big names like Google and OpenAI left rival Scale AI when its CEO switched jobs.
With other competitors like Surge AI also expanding fast, the race for top-notch training data is definitely on.
