Project Proximity

Claude Build Day

Project Proximity turns a company name into a territory-aware Equinox corporate-partnership page in about 45 seconds: the nearest Equinox club and walk time, cited research, a fit score, three audience views (AE / GM / Exec), and a prepared outreach draft that a human reviews and sends (never auto-sent). The same proximity engine is also exposed as a referral agent through a five-tool MCP server. What was built today • Deployed and public (loads logged-out): nine real company pages — Anthropic, Figma, Perplexity, Replit, Granola AI, Williams-Sonoma, Airbnb, Affirm, AIG. • Proximity for any company: the agent returns the office’s coordinates and the nearest club is computed live by haversine over 127 Equinox clubs, with a confidence tier on every distance. • Self-verification: every page is graded against an acceptance rubric; only passing pages ship, and “done” is a responding URL with cited sources — gradeable without a human. • Referral MCP agent: five dependency-free tools (nearest_club, account_lookup, generate_referral, referral_status, draft_outreach) expose the proximity engine to any MCP client. Tools create links and draft copy; they never send. • Reasoning is visible: plan → search → reconcile sources → draft → self-critique → revise, rendered on every page. • Club-network map on every page, reusing the production map component.
