Presented by Replay (codetv.link/replay) — The promise of AI is that anyone can build anything at any time. But is build really better than buy? That’s what we’re here to find out. Join your host Kedasha Kerr for episode 4 of _The Greenfield Games_.

A core challenge for companies is figuring out how to keep track of notes, projects, planning documents, and all the other information that teams need to share for healthy collaboration. Collaboration platforms like Notion provide a central hub for a company’s shared knowledge, but seat-based pricing can become a huge cost center.

Your challenge today is to build a collaboration platform. You are not going to be building a Notion clone; what we want to see is how teams can leverage modern tools to solve the same set of challenges Notion solves, but in a way that’s custom-tuned for your team’s working style.
