The source text directly confirms the claim.

The source URL matches the provided URL (https://www.trueup.io/co/xai), and while the page content appears to contain some future-dated entries (Feb 2026), the employee count of 4,000 is presented as current data without temporal qualification, consistent with the claim of '2025' headcount.
