Stop building boolean strings. Just describe the person.

Type one sentence. I plan the search, read GitHub, public LinkedIn and Crunchbase records, and the open web as it is right now, and hand back a ranked list with the reason next to every name.

1. 01Describe them

   One plain sentence. Role, city, stack, stage, whatever matters to you.

2. 02I read the web live

   GitHub, public LinkedIn and Crunchbase records, the open web. Not a database that went stale last quarter.

3. 03You read the shortlist

   Ranked, with the reasoning under every name. Open a profile, ask a follow-up, narrow it down.

• ›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

• No boolean, no filters, no seat to buy. One box.
• Read at search time, so a profile updated yesterday counts today.
• Every step visible as it runs, every name with its reason.
