Most prospecting-tool comparisons list features across products that do genuinely different jobs. It is more useful to name the jobs first, then work out which one is actually costing you pipeline, because buying the wrong category is the common and expensive mistake.
The four jobs
Find the accounts. Which companies match your best customers. Lookalike and firmographic tools do this: Ocean.io, Vainu and Goava in the Nordics, ZoomInfo’s filters at the enterprise end.
Find the person. The right role at each account, which is a different problem from listing companies and the one most tools quietly skip.
Get a contact that works. A verified email and, where it matters, a mobile that connects. This is where providers genuinely differ, covered in B2B data providers.
Reach out and follow up. Sequencing, personalization, replies, and the CRM record afterwards. Outreach, Salesloft, Reply, Lemlist and Apollo’s bundled sequencer.

Apollo
Apollo is the default first purchase because it covers three jobs at a low price. The catch is the credit maths and the assumption someone runs it weekly; see Apollo alternatives.
Cognism and ZoomInfo
Cognism and ZoomInfo are the serious data platforms, European and American respectively, and the geography is the deciding factor more than the quality.
Clay
Clay is the power option: waterfall through many providers, enrich against anything, automate the assembly. It rewards an operator and punishes teams without one.
Ocean.io
Ocean.io answers the first job specifically, which is worth separating out if your problem is not knowing which companies to chase.
Stalar
Stalar covers all four without you operating the tools between them, which is the actual gap in a stack assembled from the rows above. It is the agentic workspace for sales and revenue teams. Describe your market and agents map it, find the right person per company and verify email and mobile at that moment, priced per contact found. A sales brain records every prospect, conversation and touchpoint and learns from each one, and agents apply that context: drafting outreach in your voice, briefing you before meetings, keeping the CRM current from what was actually said, proposing the next move. You approve rather than operate.
How to choose
- Name the blocked job before shopping. No list, no replies, and dead numbers are three different purchases.
- Test data on your own market with 100 real accounts and count verified emails and connecting mobiles. Coverage claims are not evidence.
- Price the operator. A $49 tool that needs five hours a week is not a $49 tool, and that is the line most small teams cross without noticing.
- Check what happens after the reply. Prospecting that fills a pipeline nobody maintains produces the numbers we measured: most open deals sitting past their own close dates.
