The SIGNAL 2019 Scholarship Application is a program offered by Twilio to support underrepresented groups in tech. The event aims to make communication more inclusive for all, and the scholarship provides a free ticket to the conference and Superclass on August 5th, as well as limited travel assistance. Eligible applicants are encouraged to apply until July 31, 2019, with submissions for travel assistance closed earlier. Previous awardees have expressed gratitude for the experience and praised the program's warm and welcoming environment. The scholarship covers the cost of the conference ticket, but recipients are responsible for arranging their own expenses.
