# David Siegel

> David Siegel is the co-founder and CEO of Glide, the no-code platform that turns spreadsheets into working apps and, more recently, the first AI app generator. A designer and engineer who spent his early career building developer tools at Canonical, Xamarin, and Microsoft, he coined the term 'papercut' for small overlooked bugs in Ubuntu and created quicktype, one of the most widely used code generators before GitHub Copilot. He founded Glide in 2018 with three Xamarin colleagues after a stint at Microsoft, went through Y Combinator's Winter 2019 batch, and has raised roughly $23.7M to make building software as easy as editing a spreadsheet.
