Found: As of September 2024, Anthropic employs 1,035 people. The source also provides a timeline showing 240 employees in 2023.

Note: The claim states Anthropic had 500-700 employees as of March 2024 (early 2024, pre-rapid hiring). The source confirms 240 employees in 2023 and 1,035 as of September 2024, which is consistent with the claim's timeframe and context of 'pre-rapid hiring.' However, the source provides more recent data (September 2024) that supersedes the March 2024 estimate in the claim, making the claimed figure outdated rather than incorrect for its stated time period.
