DateStageInvestorsRaisedValuationDeal Summary
Sep 2026Undisclosed stageAxis-Dageom AI Infrastructure New Technology (lead); Cosmic Venture Partners; Flybridge$100M$4BMicro1 raised more than $100 million in a September 2026 funding round at a $4 billion valuation, with Flybridge among the participating investors and prior backers continuing to support the company. The deal followed the company’s rapid scale-up in AI training data, with the business positioned as a provider of high-quality human data and expert labor for frontier AI labs; the round was presented as a major up-round from the company’s prior $500 million valuation in September 2025. The capital raise came as Micro1 expanded from a recruiting-oriented startup into a large AI data infrastructure business serving major AI labs and large technology customers. Reported annualized revenue exceeded $500 million at the time of the announcement, and the company’s growth was driven by demand for training data, evaluation work, and expert annotation services used to improve model performance. The financing was framed as support for continued scaling of the platform and further expansion in the AI data supply chain. Micro1 is a San Francisco-based company founded in 2022 by Ali Ansari and focused on supplying human experts and training data services to AI companies. The business had previously been valued at $500 million in a September 2025 financing round and later became one of the fastest-growing private AI infrastructure vendors, with customers including frontier AI labs and large technology companies.

Sep 2025Series A01 Advisors (lead)$35M$500MMicro1, a three-year-old San Francisco-based startup founded by Ali Ansari, provides a platform for AI labs and enterprises to recruit, manage, and leverage human experts for high-quality data labeling, evaluation, and training of frontier AI models, positioning itself as a premium alternative amid market shifts like the Scale AI client exodus following Meta's investment. The company raised $35 million in a Series A round on September 12, 2025, led by O1 Advisors (co-founded by former Twitter executives Dick Costolo and Adam Bain), at a $500 million post-money valuation. This funding supports building an AI platform for human intelligence, focusing on AI interviews for vetting, talent performance management, and a data platform used by leading AI labs, Microsoft, and Fortune 100 companies. Micro1's traction accelerated dramatically in 2025, with annual recurring revenue (ARR) jumping from $7 million at the start of the year to $50 million by the time of the Series A announcement in September, driven by demand for domain-expert data labeling and AI agent evaluation services as clients like OpenAI and Google sought alternatives to Scale AI. By late 2025 or early 2026, the company claimed to have surpassed $100 million ARR, more than doubling the September figure, while managing thousands of experts across hundreds of domains, many earning near $100 per hour. The platform addresses needs in AI model training, robotics data, and enterprise AI agent development, targeting a projected $100 billion annual market. Adam Bain is joining Micro1's board, emphasizing the company's speed and role in providing net new human data essential for advancing AI models. Micro1 differentiates through high-quality, expert-driven services rather than low-cost labor, capitalizing on industry concerns over data proprietary risks and the shift toward synthetic data supplemented by human evaluation at scale. The round and growth reflect broader AI training data market dynamics, with Micro1 aiming ultimately to optimize human-job matching in a post-AGI world.
