A Lisbon-born enterprise translation platform that pioneered the hybrid machine-plus-human-editor model for multilingual customer support and content. Built TowerLLM, a translation-purpose-built LLM, and authored COMET, the open-source quality metric much of the MT industry benchmarks with — so quality estimation is native to the workflow. Acquired by TransPerfect in 2025, it continues as a brand and business unit with its models feeding the GlobalLink portfolio.
