What tribes are, is a very simple concept that goes back 50 million years. It's about leading and connecting people and ideas. And it's something that people have wanted forever.

Great projects, like great careers and relationships that last, are gardens. They are tended, they shift, they grow. They endure over time, gaining a personality and reflecting their environment. When something dies or fades away, we prune, replant and grow again.
