US-based Nylas, the unified communications API for integrating software with email, calendars, and contacts, has secured $16 million in Series B funding to expand the company and increase market dominance.

The funding round was 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' goal is to become the default tool for developers building applications that integrate with inbox data. In the API 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," said Gleb Polyakov, CEO of Nylas.

"We believe Nylas has an opportunity to be the communications layer for every major software company, from SaaS companies to ISVs," said Andrew Parker of Spark Capital. "The company has incredibly strong growth and we're thrilled to help take them to the next stage."

Nylas powers the communication layer in software applications for customers like Newscorp, Dialpad, Salesloft, Pipedrive, Hyundai, and Ellie Mae. The Nylas API handles more than 100 million API requests per day, and has seen over 22,000 new developers sign up to test the platform this year alone. Nylas has more than doubled in annual recurring revenue (ARR) in the past year and plans to continue this growth trajectory with the Series B funding.

"Nylas abstracts away the complexity of syncing and sending email data; not to mention the ongoing maintenance and security concerns that companies would otherwise have to dedicate entire teams to," said Christine Spang, Nylas' co-founder and CTO. "You can't take any shortcuts with security when you work with email data."

Nylas has received SOC-2 Certification and encrypts 100 per cent of the data that passes through the API, a company statement said. – TradeArabia News Service
