I have just launched and am actively looking to get pilot companies to test my product but find it difficult in the recruiting space.
Social Proof (customer testimonials), Press or Analyst Coverage is a key driver in checking-out new tools. Unfortunately, there is such a significant number of vendors offering recruiting solutions that it's difficult to get a customer's attention, even with a free offering.
I would focus on your messaging: Why are you better than similar solutions and what proof or anecdotal evidence can you offer?
Also, LinkedIn ads targeting just recruiters or HR execs can be effective (though expensive).
Happy to talk through this with you as I have built products in this space that have achieved product/market-fit.
