Participatory Research

Mobile + TV Dual-Screen

Prototyping

A tool that helps groups actually pick something to watch together, instead of scrolling for thirty minutes and giving up.

Over 40% of streaming sessions have more than one person, but every algorithm assumes one account, one person. When a group sits down, there's no way to negotiate. Someone hides what they want, someone always gives in, and eventually everyone just pulls out their phone.

NightCall uses private input on phones, a constraint matching engine, and a shared reveal on TV. Everyone sets dealbreakers and preferences privately, the system finds what works for the group, and the final pick feels like an event instead of a compromise.
