Hi:
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.
If you wish to discuss, send me a PM through Clarity for 15 free minutes.
Cheers,
Kerby
