30-second summary
Path launched 2010 with a 50-friend cap (later 150), a photo-first feed, and a pitch as the "personal network" for close relationships only. The app attracted a vocal creator-class following through 2011-2012 but was unable to scale its design-led intimacy while also meeting investor growth expectations. A February 2012 revelation that the app uploaded users' entire address book to its servers without permission produced durable brand damage. Subsequent feature expansion, a 2014 pivot to Path Talk messaging, and a 2015 acquisition by Daum Kakao for a reported "low eight figures" preceded the 2018 shutdown.
The Pitch
A mobile-only "personal network" where the limit was a feature. Early Wayback captures (2010-2011) position Path as the anti-Facebook — no games, no ads, no extended family, just "your closest friends and family." The feed was photo-and-moment first, not status-first. The 2012 captures foreground the 150-friend cap (expanded from 50) as part of the Dunbar framing. After the address-book scandal the site messaging shifted toward trust, privacy, and the ad-free promise. By 2014 Path Talk introduced messaging + concierge services (Places, restaurant reservation via SMS to a human agent) — an acquisition-bait feature that read as a pivot away from the original intimate-feed thesis.
Five Causes of Death
Market
The market for a Dunbar-scale intimate social network is real but structurally non-venture. Users who want intimacy with 50-150 people do not generate the engagement depth per-user that sustains ad-monetized or subscription-scaled revenue. The category worked as a feature (Instagram Close Friends, Snapchat best-friends list, iMessage groups) but could not stand as an independent product because the behavior was already absorbed by messaging apps users already had on their phones. Path competed for screen time with iMessage and WhatsApp and lost — neither required a separate download or a separate graph.
Product
Path shipped one of the most design-celebrated mobile apps of the 2011-2013 era (Wilson Miner's visual craft, the ink-well menu, the red thumbs-up). The product problem was not craft — it was that intimate social is a low-frequency behavior and the app could not survive the competition for daily opens against higher-frequency alternatives. Feature expansion (Moments, then Sleep tracking, then Talk) diluted the original "what are you doing right now with your close friends" wedge without creating a compelling replacement. The Places concierge inside Talk was genuinely novel but was the feature of a different product.
Team
Dave Morin came from Facebook platform, which is exactly the background that produced the address-book upload pattern — treating the user's contacts as a growth-loop input. Shawn Fanning (Napster) brought distribution instinct but was not deeply engaged in the product's second half. The team scaled to ~80 people in San Francisco without the acquisition-and-retention specialist that the problem required. The board (Kleiner Perkins, Redpoint, Index) pushed for growth metrics Path's thesis could not generate, which contributed to the feature dilution.
