Greetings,
I found that your youtube channel has only 3 videos, each is 10 years old and obsolete. For me, YT videos are some of the best ads one can make for its software. I would suggest you take some time to create some new ones. This does not take very long and is easy to do, and I bet this would pay off easily.
Create thee basic ones:
- introduction to every product (2min max)
- basic use for each product with examples (10min max)
- specific video for the most used features (10min max)
- somewhen down the road super specific videos for features like dynamic folders with Bitwarden/Lastpass/whatever
All you need is a screenrecorder and a proper mic (!!), and there you go. Make small and easy to digest junks. People will appreciate it, I swear 
I know you are a small team, but this can be done with little time and efforts.
Best
Johannes
