Same prompt, your brief. Change a word and I will run it again live, against the open web, and rank what comes back.

Try it on your own search

Stop building boolean strings. Just describe the person.

Type one sentence and I plan the search, read GitHub, public LinkedIn and Crunchbase records, and the open web live, then hand back a ranked shortlist with the reasoning behind every name. No filters to learn, no export to clean up, no sales call to sit through.

  • One sentence in, a ranked shortlist out. No boolean, no filters, no seat to buy.
  • Read live at search time, not from a database that went stale last quarter.
  • Watch every step as it runs, and see why each name made the list.
