Nylas, a US-based developer of communications software development technology, received $16.2m yesterday in a series B round that included Slack Ventures, a corporate venturing subsidiary of communications platform developer Slack.
The round was led by Spark Capital, a venture capital firm that is also a partner of Slack subsidiary Slack Fund, and included Industry Ventures, ScaleUp, 8VC, Great Oaks Capital, Rubicon Venture Capital and JC2 Ventures.
Nylas produces software that helps developers connect applications to functions like email, calendar and contacts and the technology powers integration between apps for corporate clients like Newscorp, Hyundai and Ellie Mae with email providers worldwide.
The company has now received a total of approximately $30m in funding, according to press reports and news releases, and Spark Capital general partner Andrew Parker will join the board of directors at Nylas.
8VC’s predecessor firm, Formation 8, led an $8m series A round for the company in 2015 with participation from existing backers Great Oaks, Fuel Capital, SV Angel and Data Collective. It raised a further $4m from undisclosed investors in December 2017.
Gleb Polyakov, chief executive of Nylas, said: “Nylas’ goal is to become the default tool for developers building applications that integrate with inbox data.
“In the API (application programming interface) world, Stripe is viewed as the trusted payments API, Twilio is the trusted SMS/voice API. Now, Nylas is becoming the trusted API for integrating with email, calendar and contacts data.”
