TenthBit Inc. was founded in 2012, in sunny California. The founders, having been disconnected from their significant others while being a part of the YC program, found that they were repurposing many other services to talk to their partners. After many frustrating skype calls, and international text messages, they decided to build Couple. The app now has over two million downloads on iOS and Android and has helped couples send over a billion messages to each other.

Trello transforms project organization into an intuitive visual experience using the kanban board methodology that has revolutionized how teams track work. The platform's simplicity is its superpower: anyone can understand a Trello board at a glance, with cards representing tasks that move through customizable columns representing workflow stages. Trello excels in environments where visual project tracking is more valuable than complex feature sets, making it the go-to choice for content creators, marketing teams, and small businesses who want to get organized quickly without extensive training. The platform's power-up system allows teams to extend functionality through integrations with time tracking, calendar syncing, and automation tools, while maintaining the core simplicity that makes Trello accessible to team members of all technical skill levels.
