What is a B2B lead finder?

A B2B lead finder researches companies against your ideal customer profile. A useful prospect list connects each account to evidence about its industry, business model, size or location, with the source and date beside the claim.

Keep the lead list's qualification gaps and rejected accounts visible. Funding, hiring and product launches can suggest a conversation, but they do not establish purchase intent. A company with an unknown required field remains a candidate to verify.

What can you build a prospect list from?

Signals that are public, dated, and checkable.

  • Funding and expansion

    Rounds, new offices, and stated plans to build out a function, with the announcement date.

  • Hiring signals

    Open roles that reveal which team is being built and what problem it is expected to solve.

  • Product and launch activity

    Releases and public roadmap changes that move a company into or out of your market.

  • Role and buying maps

    Role-level hypotheses for who may evaluate or influence a purchase, with evidence still to verify.

How a prospect list becomes outreach worth sending

A list is the input. The workflow below carries each account's signal into a draft that references it, instead of congratulating everyone on the same funding round.

Prospect list builder FAQs

Does it return contact details?

This tool builds company account lists and role hypotheses. Researching people or business contact details is a separate step using appropriate public sources or an authorized provider; it does not reveal private contacts or send outreach.

How current are the signals?

Each supported signal carries its source and date. Old, conflicting or unavailable information should remain visible rather than being presented as current evidence or treated as zero.

Can it apply my ICP exactly?

State your required criteria and exclusions. The result separates supported matches, candidates with missing evidence and rejected accounts, so you can review the filter before expanding the list.

Okou also has the similar company finder, the company research tool, the linkedIn people search, the AI competitor analysis and the AI proposal generator.
