Mercor, a startup that connects companies like OpenAI and Meta with domain experts needed to train and refine their foundational AI models, is in discussions with investors for a Series C round, according to a marketing document viewed by TechCrunch and two sources familiar with the deal talks.
Felicis, a returning investor, is considering doubling down on the company for the Series C, according to two sources. Felicis declined to comment.
The company is currently targeting a valuation of $10 billion or more, one person said. That’s up from an $8 billion target valuation that the company discussed a couple of months ago, one person said. However, terms of the final deal could still change.
The company has told potential investors that it already has multiple offers. VCs have been reaching out to Mercor preemptively with offers valuing the company at as much as $10 billion, the Information previously reported.
TechCrunch also understands that the company has brought on at least two new investors to raise funds for the potential deal through special purpose vehicles (SPVs).
The company’s previous round was announced in February – a $100 million Series B at a $2 billion valuation led by Felicis.
Founded in 2022, Mercor is approaching $450 million in annualized run-rate revenue, one person said. The company told TechCrunch in February that its annual revenue (calculated by multiplying the latest month by 12) had reached $75 million at that time. In March, Mercor CEO Brendan Foody posted on X that ARR was $100 million.

The company has told investors it is on track to hit the $500 million ARR milestone faster than Anysphere, the startup that makes AI coding assistant Cursor, according to one source familiar with the situation. Anysphere famously hit $500 million in ARR about a year after its product launched. Unlike Anysphere, which is still burning cash, Mercor generated $6 million in profit in the first half of the year, Forbes reported.
Mercor earns revenue by providing companies with specialized domain experts to perform AI model training — such as scientists, doctors, and lawyers — and charging an hourly finder’s fee and matching rate for their work.
The company claims to supply data labeling contractors to five top AI labs, including Amazon, Google, Meta, Microsoft, and OpenAI, as well as to Tesla and Nvidia. According to sources, an outsized portion of its revenue is coming from a subset of those brands, including OpenAI.
To further diversify its business model, Mercor has been telling investors that it is adding more software infrastructure for reinforcement learning – a training method where a model or agent’s decisions are verified or disputed, enabling it to incorporate feedback and improve over time. The company also intends to eventually build an AI-powered recruiting marketplace.
Still, Mercor faces competition from companies like Surge AI, which is reportedly in talks to raise funding at a $25 billion valuation, as well as from Turing Labs and other data labeling firms like Scale AI that are also expanding into RL services. Some believe that OpenAI’s recently launched hiring platform could lead the AI giant to create its own human-expert-powered RL training service.
When reached for comment, Foody told TechCrunch, “We haven’t been trying to raise at all,” and, “We turn down offers every month.” He also said the company’s ARR is higher than $450 million. However, he clarified that the company’s revenue includes the total amount that customers pay Mercor for services before its contractors receive their portion. He added this is a common accounting practice recommended by audit firms and used by competitors Surge AI and Scale AI.
The startup was co-founded in 2023 by Thiel Fellows and Harvard dropouts Brendan Foody (CEO), Adarsh Hiremath (CTO), and Surya Midha (COO). All three co-founders are still in their early twenties. To take the company to the next level, Mercor recently appointed Sundeep Jain, a former chief product officer at Uber with decades of experience, as its first president, Forbes reported.
Mercor was recently sued by competitor Scale AI for misappropriation of trade secrets. Scale AI alleges that one of its former employees who later joined Mercor “stole more than 100 confidential documents concerning Scale’s customer strategies and other proprietary information,” according to a copy of the lawsuit TechCrunch previously reviewed.
