Careers at Twilio


Twilio’s mission is to enable developers to change the world of communications forever.


Jeff Lawson, an engineer from Michigan, was tired of dealing with the expensive contracts and equipment associated with his companies’ telecommunications operations. He dreamed of being able to add communications into his businesses’ workflow in the same way he could add code to his software – specifically, enabling app developers to embed voice into their applications. In 2007, he met with twenty angel investors and venture capitalists, none of whom bought into his vision.

He forged ahead anyway, partnering with Evan Cooke and John Wolthuis to form a firm shortly after the financial crisis hit in 2008: Twilio. The company allowed clients’ developers to embed voice, video, messaging, and authentication directly into applications. They turned the service into a platform, and despite initial competition, the apps based on it began to achieve significant success. One called GroupMe was purchased by Skype for $85 million; Beluga was acquired by Facebook.

However, the company first truly came to prominence when an app built by Lawson to “Rickroll“ people (a prank involving an unexpected appearance of the music video for the 1987 song "Never Gonna Give You Up" by Rick Astley) exploded in popularity. Shortly afterwards Twilio unveiled Twilio Voice, an API for making and receiving calls that was hosted in the cloud. This was followed by a text messaging API in 2010 and SMS shortcodes in 2011.

The company’s successful rollouts attracted investors. In the next few years, it was able to raise $233.7 million in six rounds of funding from 23 investors. Prominent clients included Home Depot, Coca-Cola, Dell, Sony, and Nordstrom. It continues to grow quickly with over 300 employees and more than 560,000 developers using the service.

Benefits at Twilio

Business model of Twilio

Customer Segments

Twilio has a niche market business model, serving a specialized customer segment. Its products target companies that want to embed telecommunications features into applications.

Value Proposition

Twilio offers two primary value propositions: customization and flexible pricing.

The company’s platform has a number of options offering customers flexibility.  They can build applications with any programming language that communicates standard HTTP. Also, they can ship and iterate new features leveraging their existing technology stack. Lastly, they can scale volume up and down at short notice without any code changes.

The company offers a “pay-as-you-go“ pricing model and automatic volume discounts that scale up and down with usage. This makes it a more cost-effective option than those of similar competitors.
