Twilio: Flexing its Muscles

Have you ever ordered an Uber, signed up for Netflix, booked a stay at an Airbnb, ordered a pizza on the Dominos mobile app, or received a text message after entering a password to verify it is you? If so, you have used Twilio.

Twilio’s mission is to fuel the future of communications. Founded in March of 2008, Twilio provides a platform for developers to easily integrate voice, video, messaging, and email into their apps. Before Twilio and other communications-as-a-service companies, developers would have to set up servers, networking infrastructure, and develop agreements with telephone companies to route data, which is incredibly complex and capital intensive. Very much akin to how Amazon Web Services (AWS) allows easy deployment and scale of applications, Twilio enables easy deployment and scale of communications.

Twilio is a story stock. It is a young company with first mover advantages going after a massive market with two great leaders at the helm. The most significant challenge with this valuation is determining where Twilio’s story goes: Is this an API company that focuses on basic, low-margin messaging services that are easily replicable; or is this a sticky, communications disruptor with massive potential ahead of it? I believe the market misunderstood Twilio as the former when it lost a portion of Uber’s business and is only starting to recognize Twilio’s real potential. I think the release of Twilio Flex is the first step in a long journey of disruption.

So What’s Twilio’s Opportunity? Twilio does not fit neatly into an existing market as it is disrupting multiple existing communications markets. According to Twilio, their total addressable market is $66B subcategorized into email, programmable authentication, programmable voice & video, and programmable messaging as per their SendGrid acquisition investor presentation.

The following was found looking for other perspectives on Twilio’s TAM:

  • Market Research Engine predicts the global telecom API market will grow at a CAGR of 24% from 2015 to 2022 and is expected to reach $325 billion by 2022.
  • Markets and Markets expects the global telecom API market to grow from 93.69 billion in 2016 to 231.86 billion by 2021 at a CAGR of 19.87%
  • Zion Market Research expects that the global telecom API market was capitalized at almost USD 66.37 billion in 2016 and is likely to cross almost USD 218.84 billion by 2022, developing at a CAGR of almost 22% from 2017 to 2022.

The Combined Company Twilio is still undervalued even after paying too much for SendGrid including cross-selling synergies increasing growth by 5%, 3%, and 1% for the next three years.

Twilio Valuation

The Pricing

Twilio should be valued against its peers on an EV/Sales basis due to the lack of profits from the majority of high-technology firms. Data was collected from S&P Capital IQ referencing 181 of its publicly traded peers with a market capitalization higher than a billion and within the internet software and application software industries. The key drivers of the EV/Sales multiple are deconstructed using a stable growth model.



A significant regression where the 𝑟2 was within an acceptable range was not able to be created with the above. Expanding ATOM into gross margin, SG&A margin, R&D margin, and the effective tax rate; and adding an earnings dummy gave the regression more to work with. A correlation matrix was run to determine the best-suited variables, which are highlighted in bold. The regression and regression equation are shown below with the names in the regression equation shortened for readability.

Twilio has a predicted EV/Sales of 10.39 with an actual value of 17.4. SendGrid has a predicted EV/Sales of 10.32 with an actual value of 6.

The Conclusion

Both the valuation and pricing tell a different story. So while it would be nice to see both tools pointing in the same direction, I am firmly in the intrinsic value camp, and I am a buyer of Twilio at the current levels with a close eye on cash usage while looking for changes in the narrative.
