Challenge
Three people, one TV, thirty minutes of scrolling. Recommendation engines assume one account means one person. They don't know how to serve a group. So everyone compromises, nobody's happy, and half the night is gone before you hit play.
Approach
I ran a participatory design workshop to observe how real friend groups pick movies together. Four behavioral patterns came out of that. I designed a four-phase flow where everyone privately sets dealbreakers, picks a vibe, then votes on the matches. The whole thing runs in under three minutes on any phone browser.
For NightCall, the core insight was that group decisions break down because of social pressure, not bad algorithms. NightCall separates private input from public outcome so everyone's honest, and a karma system makes sure the same person doesn't lose every time.
