Micro1, a competitor to Scale AI, raises funds at $500M valuation

Micro1, a three-year startup that helps AI companies to find and manage human contractors for data tennis and training, has raised a series of A-financing round of $ 35 million that the company appreciates $ 500 million. De Ronde was led by O1 advisers, a venture capital company co-founded by Dick Costolo and Adam Bain, the former CEO and COO of Twitter.

The startup is one of the many companies that want to fill in the gap in the data market created by recent changes with AI scale. After Meta $ 14 billion had invested in scale AI and hired his CEO, AI Labs, including OpenAi and Google, said they were planning to break the ties with the startup, probably about concern that their investigation could end in the hands of Meta. (Scale AI denied that the confidential information shares with Meta as part of his partnership).

However, AI Labs still need these data services and startups such as Micro1 are intended to pick up the play.

Micro1 CEO Ali Ansari – who is only 24 years old – WAN tells that his company has worked with leading AI Laboratories, including Microsoft, as well as various Fortune 100 companies. Ansari said that Micro1 now generates $ 50 million in annual income (ARR), an increase of $ 7 million at the beginning of 2025.

That is still far removed from larger competitors such as Mercor, who generates more than $ 450 million in Arr and Surge, who is reportedly brought in $ 1.2 billion in 2024. However, the growth and acceptance of Micro1 at AI Labs seems to be growing at a healthy pace.

As part of the new financing, Micro1 also adds Bain to his board of directors, in addition to Joshua Browder, founder and CEO of the AI ​​-Legal Assistant DonotPay.

“Really the only way models now learn is through net new human data. Micro1 is the core of providing that data to all frontier labs, while moving at speeds that I have never seen before,” Bain said in a statement to WAN.

All these companies – Micro1, Surge, Mercor and Scale AI – deliver AI Laboratories with access to a large basis of human contractors who can label and generate data for AI training. It has become a crucial service that companies such as OpenAI, Anthropic, Meta and Google have to build to build advanced AI models.

Scale AI would first dominate this space, with the first insight that it could pay relatively little for low-skilled contractors around the world to help label data for AI model training. Ansari, however, says that the requirements of AI laboratories have shifted in recent years and that companies now need high-quality data cashings from domain experts such as senior software engineers, doctors and professional writers to improve their AI models. The most difficult part was recruiting these kinds of people.

This led Micro1 to build his AI recruiter, Zara, who interviews candidates and veterinarians who register for work as one of the contractors of the company, or as Ansari calls them, experts. Micro1 says that Zara has recruited thousands of experts – including professors from Stanford and Harvard – and that the company intends to add hundreds of more every week.

The market for AI training data seems to change again. Now many AI laboratories are interested in working with startups to develop ‘environments’ -virtual workplaces that can be used to train AI agents at simulated tasks. Ansari says that Micro1 is building new offers in the environmental space to meet this demand.

Fortunately for startups such as Micro1, AI Labs seem to be working together with multiple training data providers. The nature of the company is such that it is difficult for a company to handle all data needs of one AI Lab. That means there are enough things to go around for the time being.
