I use Crustdata for b2b leads. What’s your issue with Sales navigator? It’s the most accurate source of B2B data. Almost every database in the market gets their data from there. My issue with Sales Nav was I couldnt export the data i needed into my system. Crustdata has APIs that can integrate into any system including your CRM and automation tools, so you can check it out. The data is pretty accurate when you use realtime enrichment. I have come across alternatives, but havent tested it out myself - cognism, lusha, zoominfo (too expensive), apify.
