Congrats guys, look cool! My 2 bits of advice 1) Immediately give me the clear and compelling value proposition (and a side by side) why i want to even explore the demo VS notion and slack. I use notion mostly, slack for certain communities (which I hate), and there are so many alternatives like Obsidian, Basecamp, Monday etc to organize that trying another one even with AI has me hesitant. I would like to immediately see the value proposition as to why it is better than Notion which has AI, and expresedly what my value prop would be to spend time trying it 2) Data safety clear and upfront. Is it encrypted? Can your engineers see my data? Can I export at any time? This and future pricing if I use it and can estimate SaaS growth costs when company is at 5-10x are the biggest deciding factors on a new SaaS and if I have to do mental gymnastics on either I am usually not even going to demo. Look cool and hope these tips help!

I feel like I have a superpower being able to control Slack, Gmail, and other work tools on Den. I tried generating leads and set a targeted amount. It curated the list, saved it in a file, and I downloaded it.

The idea is great. Being able to mix a Slack/Notion/AI agents, all in one place, that's clearly needed. However, after getting a few results from my agents, they do not deliver anymore. It keeps telling me it searches. Maybe i've reached the max of credits i can use. Also, the scheduling for the Agent to automatically run, never worked.

Oh wow, Slack, Notion & my Email had a baby! So many agents to play with. I just realised I have played with 40 agent templates in less than 2 hours. Could not achieved this with output with any other platform that I know of. Amazing work Justin & Linus.

Works great. Would love to have a desktop extension (think of the Apollo Chrome extension for LinkedIn), so I can instantly spin up an agent without having to open Den as a separate page/app. Create an agent within 20 seconds of wanting to.

Den is great. I use it for personal note taking/knowledge management and it does that super well, on top of being a great place for team members to collaborate. Love the UI choices.

Best fit for knowledge workers and teams wanting automation without code. Improving transparency around data access, trust, and privacy would go a long way in making the product even stronger and more widely adopted.

Such a great product! Our meeting ended early today because everyone already shared their plans async beforehand. Totally caught us off guard in the best way.
