I think it's not exactly like Trello, but it's very similar. Trello is free [for a small number of users?], so to convince people to signup to an paid alternative it's important to explain the advantages.

We embrace a kanban style task management. Not sure how you deduced that we look like trello. Besides we offer so many more services such as Sketch (whiteboard), Chat, Video Conferencing

Love that you are engaging with the commenters. Maybe it's worth taking some of this feedback and applying it to your homepage, or maybe create some click tracks from your homepage to some of these other feature pages to take people on a the buyer journey and try to convert them into leads?

Thank you! This is a truly genuine product that made my life much easier and so all I wanna do is share it with the world and make everybody else’s life a little bit easier as well
