Pinboard: a paid bookmarking site that bought its rival

Q: Why did Pinboard work?

Charging money protected the service. Cegłowski wrote that if Pinboard had not been paid, it could not have stayed up on 16 December and he would have had to raise money or close signups (Anatomy of a Crushing, archived). Simple, overprovisioned infrastructure. He describes a big web server, a bigger database server and no heavy caching layer. Median page times stayed under a third of a second during the rush, which he says earned "terrific word-of-mouth" (Anatomy of a Crushing, archived). A rival's mistake became a channel. The Delicious exodus brought "ten million bookmarks, eleven thousand new users, forty-odd refunds" (Anatomy of a Crushing, archived).

Q: What didn't work for Pinboard, and what are the risks?

Growth was flat. Active users in the table go from 16K in 2011 to 29K in 2017, and revenue dipped to $160K in 2015 (Eight Years of Victory). One person is a bottleneck. In 2017 Cegłowski wrote that travel meant he "sometimes ignored support emails for weeks at a time" (Eight Years of Victory). The rush hurt new users. Imports queued up, activation emails were delayed, and paid archiving users bought a feature they could not yet evaluate (Anatomy of a Crushing, archived). All figures are the founder's own and run only to 2017. We found no later public revenue table and do not estimate current numbers.

Key takeaways

Pinboard's own anniversary table shows revenue of $117K in 2010 rising to $259K in 2017, with $0 in funding.
When Yahoo's plan to sunset Delicious leaked in 2010, Pinboard gained eleven thousand new users and stayed online.
In 2017 Pinboard bought Delicious and asked its users to move to a $11/year Pinboard account.
