Unified Communications API Nylas Closes $16.2 Million

Nylas, the unified communications API for integrating software with email, calendars, and contacts, secured $16 million in a Series B funding round led by Spark Capital with participation from Slack Ventures, Industry Ventures, and ScaleUp, joining existing investors 8VC, Great Oaks Capital, Rubicon Venture Capital and John Chambers’ personal fund. Andrew Parker, general partner at Spark Capital, spearheaded the deal and will join Nylas’ board of directors.

Nylas is designed to power the communication layer in software applications for customers Newscorp, Dialpad, Salesloft, Pipedrive, Hyundai, and Ellie Mae. The company’s Nylas API handles more than 100 million API requests per day and has 22,000 new developers signed up to test the platform. Nylas has reportedly doubled in annual recurring revenue in the past year and plans to continue this growth trajectory with the Series B funding.
