Lipsi

Lipsi was a Vancouver anonymous-messaging app: users posted a personal link on Instagram and got unsigned replies back, or searched a nearby person by first name and opened a chat without revealing who they were. Founded by Matthew Segal, it reached roughly seven million users in Canada, the US and the UK.

About

Lipsi let people message each other anonymously. Matthew Segal, who grew up in Vancouver, had the idea as an undergraduate at Yale and built the app with engineers in British Columbia and Ukraine. It worked two ways: search someone by first name, or browse a list of users nearby ordered closest-first. A later "Lipsi Link" feature — the one Segal demoed at TechVancouver in December 2017 — let anyone drop a link in an Instagram bio and collect anonymous replies from followers who had never installed the app; a seven-digit code let the sender continue the conversation inside the app without being identified. On stage Segal described first targeting UBC's Greek system, about 5% of campus, and finding it too small and too self-conscious to spread, then pivoting to the general public. He also described a planned feature connecting users anonymously to registered counsellors, and said the app was branded as a social product first so that mental-health support would be one feature rather than the whole identity. By April 2018 Lipsi was climbing the US App Store charts; Segal later told BCBusiness it had about seven million users. Like the anonymous apps before it, it drew school-safety complaints in the US, and the company partnered with Google's Perspective API to filter abuse. The app is no longer listed on the App Store, though lipsi.ca still serves its old marketing site.
