- There's a heavy emphasis on performance. Are you sure customers care about that more than real time collaboration and self hosting? (I don't think they care about CRDTs.)
- If I am experiencing pain because eg my Notion wiki is too big and is having serious performance issues, what I want to hear immediately is how you are going to help me migrate from Notion to your solution. Notion has a feature to export an entire workspace; can you ingest that and get me spun up with your product?
- If I hear something is open source I expect to be able to try it out immediately without logging in. It looks like you can do that but when you hit "Get Started" it puts you into a registration flow.
- You might take a look at how Zed is marketing themselves, they have a similar pitch (performance + realtime collaboration). The first thing they try to show you is a video where they demo the product and show how fast it is. (I think they focus too much on performance though.)
- The frontend is a web app right? If possible rather than a video, embed the interface in your landing page. If possible, let them share their document and try out collaborating on it with someone or with another browser tab. Give them an opportunity to be impressed.
I respect anyone who posts their work. Best of luck.
