Twilio

Developers at companies like Airbnb, Lyft, and Stripe use Twilio's APIs to add messaging, voice, video, and authentication to their applications. The platform powers over 10 million developers worldwide, handling everything from two-factor authentication texts to customer support calls—the communication infrastructure that modern apps rely on but users never see.

Twilio has been remote-first since 2020, formalizing what they call "Open Work" in 2022. The roughly 5,000-person team is distributed globally, with 3,189 employees working remotely or from smaller regional offices. The largest hubs are San Francisco (515 people), Denver (255), and Bengaluru (238). Engineering makes up about 45% of the company.

The company practices "Focus Fridays"—a dedicated day for deep work with few to no meetings. Employees receive a one-time remote work stipend and access to company-wide breaks throughout the year. Despite industry-wide return-to-office mandates, Twilio's leadership has publicly committed to maintaining remote work, citing it as the top reason candidates join the team.
