Lisbon-headquartered Unbabel, a startup that has developed what it describes as an "AI-powered, human-refined" translation platform that makes it more cost effective to conduct business globally, has raised $23 million in Series B funding. The round is led by Scale Venture Partners, with participation from Microsoft Ventures, Salesforce Ventures, Samsung Next, Notion Capital, Caixa Capital, and Funders Club. It follows a $5 million Series A round in October 2016. A graduate of Y Combinator's 2014 Winter Batch, Unbabel uses AI/machine learning, augmented with a network of around 55,000 human translators, to power translations across multiple text-based content and communication, such as email, chat, websites and more. This is delivered via an API and integrations with the likes of Salesforce, Zendesk, WordPress, Mailchimp, and other enterprise software.
