In a partnership with Union Square Ventures, Twilio is hosting a contest for developers to submit their Twilio-powered startups, with the help of Fred Wilson, Albert Wenger, and Brad Burnham in selecting the winner. The three partners will evaluate submissions based on how they leverage Twilio to create something with network effects or accumulate data assets, rather than focusing on technology specifics such as programming languages or features. This approach emphasizes innovation over technical details, allowing developers to showcase their creativity and expertise in using Twilio's platform.
