Best for is the opening line of that tool's verdict. The full verdict is below. Pricing is the catalog note, not a quote I calculated.
B2B contact and company database with built-in email sequencing, calling and a Chrome extension.
For small teams that want contact data and email sequencing in one tool. Whether it fits depends on how well the database covers your ICP, so test a few hundred records from your own target list before you commit. Verify emails with a separate tool before anything sends.
B2B contact and company database with intent signals, an AI copilot, and sales and marketing engagement tools.
For mid-market and enterprise teams selling into the US who need deep contact coverage and will use it every day. The contract matters as much as the data, so get credit limits and auto-renewal terms in writing before you sign. Negotiate hard on the first deal.
