VentureBeat's coverage of Unbabel's $60M Series C; combined with earlier disclosed rounds, this totals $91.2M. Unbabel was acquired by TransPerfect in August 2025 — funding_total is a pre-acquisition historical figure and the company no longer raises independently.

Employees

Checked — none published

Checked 2026-08-27 and no citable figure found. Four sweeps were run and all came back empty for this company: (1) its own /about, /about-us, /company, /careers, /jobs and /team pages, pattern-matched for a self-published headcount; (2) stockanalysis.com's private-company page, which footnotes each figure to its source; (3) its Forbes company profile, which states a headcount and the month it is as of; (4) a targeted web search. Everything the search returned was a LinkedIn-scraping aggregator, and those disagree with each other by wide margins and cite nothing, so they are not used here. The field is null rather than carrying the round guess it held before.

Status

Press release · 22 Aug 2025

TransPerfect's own announcement: "TransPerfect today announced that it has acquired Unbabel," 2025-08-22. Unbabel's technologies (TowerLLM, COMET) are being integrated into TransPerfect's GlobalLink platform rather than kept as an independent brand, but its CEO stayed on to oversee integration and the open-source TowerLLM/COMET releases continue. No acquired edge: TransPerfect is not a company record in this directory.
