DEV's Worldwide Show and Tell Challenge Presented by Mux: Pitch Your Projects! $3,000 in Prizes. 🎥

#showdev #devchallenge #muxchallenge #webdev

We are so thrilled to introduce DEV's Worldwide Show and Tell Challenge presented by Mux!

Running through January 4, this challenge invites you to record a 1-minute pitch video about your project and share it with the community. Consider this our version of "Shark Tank" but without the sharks.

Have you been thinking about a project for months but haven't gotten started? Take this as your signal to start building!

Previous projects welcome too! This is your moment to show off that side project, startup, or previous challenge submission that you worked so hard on but didn't get the recognition for.

Whether it's a weekend hack, a passion project you've been refining or thinking about for months, or something in between, we want to see it!

Our Prompt 🎥

Show off any side project you're proud of. Record a 1-minute pitch video explaining what your project is, what makes it special, and why you built it. Upload the video to Mux and embed it as part of your submission!

Additional Prize Category: Best Use of Mux

Value Proposition & Audience Benefit - Who it's for and what they get out of it
Storytelling & Pitch Quality - Clarity, structure, and how engaging your 1-minute pitch is
Scalability & "Would You Invest?" Potential - How big this could be and whether it feels investable
