Pie，Andy Dunn 的线下社交应用，从活动转向“现实版 Reddit”，用户约 30 万

做的是什么生意

A US social app that helps people form and run in-real-life communities — run clubs, art markets, watch parties — with events, permanent group pages called Community Homes, and AI-assisted friend matching.

启动资金：$11.5M Series A (early 2025); backers include Forerunner, Lightspeed, Accel and angels such as Twitter co-founder Ev Williams

起因

After moving from New York to Chicago and realizing how hard it was to build a social life, Dunn — who sold Bonobos to Walmart in 2017 — founded Pie in Chicago to attack the loneliness epidemic. The first iteration was a heavy personality quiz; by late 2024 the app had pivoted toward events and was expanding from Chicago to San Francisco.

经过

Pie raised an $11.5M Series A in early 2025, paying organizers to host events and acqui-hiring the two founders behind Sparked Connections, an AI quiz that sorts attendees into groups of six likely to get along. In December 2025 it reordered the activity feed to show which friends were attending an event rather than listing events, lifting average time on app from 2 to 10 minutes. On August 25, 2026 it launched Community Homes — permanent group pages with feeds, admin and membership controls — and brought on Zoomies run-club founder Nadya Okamoto as co-founder and CMO.

结果

Still running and expanding nationally: about 300,000 users as of late August 2026, with the strongest traction in Chicago, New York and Los Angeles.

可借鉴之处

社交产品的指标可能具有误导性：Pie 使用时长提升 5 倍是因为展示了人而不是活动——当信息流不再是产品，而线下聚会才是时，留存率随之而来。
