THE TWILIO MAGIC
Our core values and
principles: The Twilio Magic
We are Builders
We love hard problems and believe in the indomitable power of people's ability to create a better world through ingenuity and resourcefulness. We reject the “can’t be done” and believe bold ideas and fearless iteration can resolve the most challenging problems for our customers and the world they operate in.
We are Owners
We take accountability and see things through. We take the long view, sweat the details, and think about how our work makes Twilio better every day. We recognize that we and others do our best work when we feel both empowered and accountable for outcomes.
We are Curious
We see ourselves as works in progress. We know that we don’t have all the answers, humbly seek the truth, and strive to get better every day. As individuals, as a company, and in our products, we seek continual progress over perfection and acknowledge shortcomings as a matter of fact. Progress comes not from avoiding mistakes or hard truths, but in learning from them.
We are Positrons
A positron is a positively charged electron. We are genuinely excited to serve and help others. We believe that positive energy is contagious and caring is critical. We seek to be bright spots for the people around us in every interaction, and we stand up and work for what we believe is good and right for our customers, our company, our communities, and the world at large.
