We speak human and machine
Localization experts who care about your users in every language
Beluga Linguistics is a professional translation agency and localization company for software and technology teams, based in Madrid since 2006. Our linguists, reviewers and project managers work with AI inside the TMS you already use.
WHAT WE BELIEVE
Expert in the Loop
Every expert is human. Not every human is an expert. For two decades, we've helped fast-growing companies and tech-driven multinationals scale into new markets, and corporates take their business digital. Our translators are native linguists and trained subject-matter experts with years of experience in their fields. That's what lets them know what to look for and judge what AI gives back. Put AI in those hands and you get better results.
Knows what to look for
Native subject-matter experts who know your field, and who learn your product, users and terminology with every release in the same Squad.
Judges the output
Two decades of localization for companies that grow fast, with review and LQA methods used inside Crowdin, Phrase, Smartling, wxrks and XTM. We've trained over 100 localization professionals on Crowdin and wxrks best practice.
Decides what ships

All within quality and information security processes certified to ISO 9001 and ISO/IEC 27001.
