WarmIntro
WarmIntro is a mobile + web app that helps adults make friends through trusted mutuals instead of cold swipes. You connect your contacts (and optionally LinkedIn) and set “friendship intents” like: new-to-city, gym buddy, board games, parenting, coworking, sober hangouts. The app finds 2nd-degree matches and asks a mutual friend to vouch with a one-tap intro template (“You two both like X—want to meet?”). It then proposes low-pressure micro-plans (30–60 minutes) at public places and handles scheduling. To reduce flakiness, users build a lightweight reliability score (show rate, last-minute cancels) and can require “confirmed” matches only. This is not magic: growth depends on network effects and good local density, but when it works it feels safer and more natural than stranger-first apps.
