About
Zapier is the dominant no-code automation platform that enables business users to connect applications and automate workflows without writing code. Founded in 2012 by Wade Foster, Bryan Helmig, and Mike Knoop, Zapier built a massive library of app integrations—now exceeding 7,000 apps—connected through a trigger-action model: when an event happens in one app (a new email, a form submission, a sale), Zapier automatically performs actions in other apps (creating a record, sending a notification, updating a spreadsheet). This simple concept enabled millions of businesses to automate time-consuming manual processes.
