Cardbox

Cardbox is one of the fastest-growing power-ups for Trello (100,000+ installs). Bootstrapped, no plans to raise VC. This is the first hire, you'll be working alongside myself. I was technical founder of Yardsale (YC S11, acq. 2015), and lead technical advisor for HBO Silicon Valley (s3). Stack: React.JS, Rails, and Redis to coordinate 1m+ synchronizations per day. Most of the UI runs in an iframe on Trello.com, which requires cross domain considerations. There are plenty of tools to add Kanban boards to Gmail, and they're all pretty successful. Kanban boards are better than lists for organizing workflows. But Cardbox is the first to do the inverse. We add a Gmail inbox to Trello. Other tools can only support some subset of Trello features, usually poorly. This 1) is harder to build (so more valuable), 2) offers better UX than a Trello knock-off, and 3) works with existing integrations, so it benefits from Trello's significant network effects. Lastly, Gmail is missing from Trello as a built-in feature but present in almost every competitor (e.g. Monday.com). They will either build or buy this, so it's important to move fast.
