Just tried Den, this is what it feels like when someone rebuilds the digital workspace from first principles.
As a founder working on AI for contract review and early-stage legal workflows, I’ve been waiting for a product where agents actually do things, not just sit in the corner. Den nails it. The flow is intuitive, the UX is sharp, and the AI moves with you.
Huge congrats to the team, this really feels like the future of how we’ll work.

@alain_augsburger +1 to everything you said!

This was very well said!

@alain_augsburger thanks so much Alain! We have worked tirelessly to make the UX great, and it's going to get 10x better from here!
A new, fascinating product that reimagines how teams can work (and how friends can make their travel plans!!). Excited to see where this goes!

@justin_lee27 🤟🤝
Den just helped me plan and optimise a travel itinerary for work, then email a booking request to my travel agent. It cut the research/admin time dramatically. I'd estimate between 3-5x. The use cases for Den in my workday are growing all the time. I can really see how it is helping humans get more stuff done....highly recommended.

@paul_lee26 wow, that's awesome. enjoy the trip!
Spent just 15 minutes with DEN and it was enough to realize this isn’t just another productivity tool, it’s a complete rethink of how digital work should flow. Feels like Slack, Notion, and AI had a baby… but better.
The AI agents are actually useful, the interface is clean, from chats to docs to workflows—feels deeply connected. Even in that short time, I could see how this could reduce busywork, eliminate context switching, and create real mental space.
Excited to dive deeper. Huge kudos to the team—DEN feels like the future of work.
