Nylas

Nylas is an API platform that lets B2B software companies plug Gmail, Microsoft, IMAP, Zoom, and 250+ other email, calendar, and meeting providers into their products without building the integration infrastructure themselves. It's the kind of plumbing that's deceptively hard to get right at scale, which is why customers like Dialpad, Clio, Wix, and Freshworks pay for it instead of building it. The company started when CEO Christine Spang and her MIT classmates hit a wall trying to access email data for an open-source client. Nylas is remote-first, has raised a $120M Series C, and offers unlimited PTO, 12 weeks paid parental leave, and 90% company-paid healthcare. For PMs, it's a developer-tools shop where the product surface is APIs and SDKs.
