We've been using AI Ark for a while now and the main thing for me is that I can trust the data first time.
The emails are good off the bat. So is the coverage, and that's the bit most tools get wrong. Normally you're picking one or the other. Either the emails verify but the coverage is thin, or you get plenty of contacts and half of them left the company two years ago. AI Ark is the first one where I haven't had to make that trade. Job titles are current, companies are current, and I'm not second guessing a list before it goes out.
The filters are the other big one. Being able to target a company that doesn't have a CFO, or a founder with no HR department, for example. That used to take a lot more messing about, with spreadsheets or complex Clay tables with lookup columns etc. , Now we can build a properly targeted list in a couple of minutes
It's also replaced a stack of subscriptions with one, at a price that actually makes sense. The API is great and the MCP is really handy too.
Elias is also super helpful and responsive in a private Slack channel.
Long and short of it, it's just simplified our whole people finding process. Really good product.
