At Erudito, we use hundreds of tools on a daily basis. Some for work, like Sketch for Product Design, After Effects for motion and Atom for development. Some are for personal use, like Steam for playing games and Twitch for watching other people play games because it’s been a long day and we can’t be bothered.
Every so often, one of us has a brilliant idea for a tool that would not only benefit the team, but would potentially make a really great product. Instead of throwing these ideas in the backlog, we vet them like a client project and if they’re good, we build them.
