Words from our clients...​

Adam and MacroLingo have supported Sansan’s global expansion for several years. Their work spans everything from defining the English used in our product UI to handling marketing and PR, all focused on delivering real value to customers. Adam and MacroLingo bring a professional, collaborative approach, building knowledge of the industry and working closely with our team to choose the right words for the right context.
Edward Senju Regional CEO, Sansan Global Pte. Ltd.
We work with MacroLingo to translate and localize our web pages, services, and internal and external marketing materials. They've supported us with extensive language and PR skills that can't be achieved by mere auto-translation. They have accurate understanding of our intentions, service is prompt, appropriate technical terms and wording for our marketing text, and clear language from a PR perspective.
Naoyuki Masuda
COO, Morgenrot Inc.
MacroLingo drafted clear, well-structured articles based on multiple project documents and quickly incorporated feedback from the projects’ funder. Their work was prompt and accurate, communication throughout the process was smooth and efficient, and the final deliverables were of consistently high quality.
