Who owns Scale AI, Inc.

Scale AI, Inc. - Profile

Scale AI is an artificial intelligence infrastructure and software company based in San Francisco, founded in 2016 by Alexandr Wang and Lucy Guo through the Y Combinator programme. It supplies the training data that machine learning models are built on, running a large distributed contractor workforce that labels images and sensor data, writes and ranks model responses for reinforcement learning from human feedback, and red teams and evaluates large language models. Alongside that service it sells enterprise software for building and deploying AI applications, and it operates the Remotasks and Outlier annotation platforms. Customers have included Google, Microsoft, OpenAI, General Motors and the United States Department of Defense, which awarded it a 250 million dollar federal contract in 2022 and the Thunderforge military planning programme in March 2025. Jason Droege, previously chief strategy officer, took over as chief executive in June 2025 when Wang left the company.

The disclosed stakes

One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.

Where each figure comes from

A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

• Meta Platforms, Inc., as of 31 Dec 2025. The $13.80bn is Meta's carrying value under the measurement alternative at 31 Dec 2025, taken from Note 5 of the FY2025 10-K, which describes it as a minority investment closed during 2025 over which Meta does not have significant influence. That figure is filed. The 49 percent non-voting stake is press reporting summarised via web search: it was not confirmed against a primary page fetched in this task, so the percentage should be treated as reported, not filed. Press also puts the deal size at $14.3bn, above the $13.80bn carrying value. source
