What are some underrated data tools on Product Hunt for lead gen or enrichment?

The other day I saw a poll on LinkedIn which said one of the biggest ongoing struggles of startups and small businesses is reliable, scalable lead generation especially beyond the usual tools like Apollo, ZoomInfo, Clearbit, etc.

Product Hunt often features some fresh and creative approaches to data. I have seen some around company enrichment, contact intelligence, trigger signals or even outreach automation.

But often PH launches get forgotten after their launch day.

What are some lesser-known or recent data tools you’ve come across on Product Hunt that help with lead gen, enrichment, or prospecting?

Let's discuss prospecting in the comments :)
