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.

• ›Staff backend engineers in NYC who shipped Rust in production
• ›Series A fintechs in SF under 50 people, growing headcount this year
• ›Maintainers of fast-growing Rust web frameworks on GitHub
