Where do sales people find new sales products to test?

Everytime I talk with a sales person while doing user research, they drop a sales product I’ve never heard of before. Where do sales people find all these products for their specific niches and use cases?

I’m creating an AI tool to help sales SDRs do research and use that research to perform an outreach task.

Does anyone have recommendations on what platforms help drive real usage of the tool’s functionalities for us to test its usefulness?

I’m not looking for fake users or a high volume of users or reviews. Just ones that will use it themselves to help them with their actual sales jobs.

Looking for sub-reddits or other forums similar to HackerNews and Quora.

Recommendations would be greatly appreciated!

Thanks!
