Background

Growing demand for specialised data to train artificial intelligence models is helping data-labelling startups expand rapidly. Micro1, a four-year-old startup, has seen its gross annual revenue run rate rise from $100 million to $500 million in just eight months, according to a person familiar with the company.

Micro1 works with professionals such as doctors, lawyers and scientists on a contract basis to provide data and evaluate AI models. The company keeps about 60% to 70% of its gross revenue, putting its net annual revenue run rate at around $150 million to $200 million.

The startup remains smaller than rivals such as Mercor and Handshake, which have reached gross annual revenue run rates of about $2 billion and $1 billion, respectively. However, Micro1’s rapid growth highlights the strong demand for human expertise in AI development.

The company is also working to improve its margins. Micro1 is producing more synthetic data without direct human involvement, including automated descriptions of video content. Some datasets can also be sold to several customers. This type of ready-made data can generate gross margins of up to 80% to 90%.

Micro1 started as an AI recruitment company before moving into data labelling. Founder Ali Ansari made the shift after seeing customers use the company’s recruitment platform to find engineers for data-annotation work.

The company also plans to build a robotics training dataset by having hundreds of people record everyday interactions with objects at home. Micro1 raised its Series A at a $500 million valuation last year and may have raised another funding round at a much higher valuation.
