I have worked with a marketing expert here on clarity and we talked about landing page and focusing on getting the user side signed up. He was very helpful and all makes sense but still not making progress. I hired a marketing person to help with messaging, but still missing something.
You've been working the marketing tactics, which is good, but I'd suggest backing up a bit.
What is the headache that your platform resolves for one side? And what about on the other side? Are these definitely pressing headaches that they're looking to address? Is your solution compelling enough to get them to change what they're doing for the headache currently? Are you sure you have identified the best target market - and validated that through customer conversations?
Solid marketing can draw people in, but if the solution doesn't address a customer need - or lands in a customer group that's not the most ideal - your efforts can fall flat.
