For brand communications we use the font Whitney. If you are a Twilio employee, our brand fonts should be pre-installed on your computer. If you have trouble accessing them please contact our IT department. If you are a vendor working with Twilio, you are responsible for acquiring your own license to use Whitney.
Please note that we do not own the fonts that we use. We pay for a specific number of licenses. That means that our fonts cannot be shared with non-Twilions or vendors. Any company or individual outside of Twilio will be responsible for paying for their own licenses to the fonts. There are exceptions to this rule (like printers). For more details please consult the EULA.
