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 applies AI/ machine learning, augmented with a network of around 55,000 human translators, to power translations across multiples 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 endeavour software.

In a bellow with Unbabel co-founder and CEO Vasco Pedro, he explained that the company plans to use the additional capital to invest further in the AI/ machine learning side of the platform, which has increasingly come into play as Unbabel scales.

Another area that he plans to bolster is sales and marketing, something that the startup hasn’t focused on very much to date( although it does have a U.S. office principally dedicated to sales, in addition to its Portugal product and engineering HQ ).

One of the challenges, he says, is educating world markets that a solution like Unbabel exists. That is, one that isn’t a binary option between machine translation, such as Google Translate, or simply hurling humans who speak more than one language at the problem.

Unbabel’s platform is designed to augment machines with humans and vice versa, and to differing degrees, depending on the type of content being translated and the appropriate trade off between accelerate and accuracy/ nuance.

For example, a customer support converse might utilize more machine translation in order to keep the conversation near realtime, whereas email is asynchronous to begin with and therefore affords the luxury of slower response times and additional human augmentation.

Unbabel is already used by well-known corporations including Facebook( Oculus ), Buzzfeed,, Pinterest, and Under Armour. Pedro reckons that the startup’s new investors with ties to Microsoft, Salesforce, and Samsung should help it penetrate business enterprises further.

Adds Nick Nigam, Principal at Samsung Next, in a statement released: “We are attracted by engineerings that break down geographic roadblocks. Unbabel, with its ever decreasing expense per term, is enabling borderless communication in a professional, scalable, and affordable manner”.
