I found Oppwiser via their Product Hunt launch. I was very interested in their Lookalike company search feature. The good: - The lookalike company finder works surprisingly well. It's not perfect all the time and for the most part, the results with lower similarity scores are much less relevant. However, the first few pages of suggestions are usually spot on. - To find competitors I usually use Google and Similarweb. I found companies that are our ICPs on Oppwiser that I haven't been able to find with other tools. That's a win for me. - They have contact data (mostly emails), and as far as I understand they are also verifying email for their deliverability. I'm no longer using Hunter for that and I haven't seen my bounce rate change. - They have integration with Salesforce so you can sync data both ways, but I haven't tried that yet.
