The story behind Effi is simple:

Livestreaming was harder than
it should’ve been.

Most platforms forced people to juggle disconnected tools, scatter their audience across platforms, and guess what was actually working. We built Effi to fix that—so creators, campaigns, and brands could focus on their message, not the mess.

What they say about us

"Effi provided us with an intuitive, yet creative way of engaging The Challenge fans during our first-ever live online casting special. We polled The Challenge social followers and YouTube subscribers throughout the special, learning about their real-time preferences to inform our livestream programming. Interactive storytelling is the next frontier of social content creation, and we’re excited to see where Effi 2.0 can take future efforts in this space."
