Traffic Distribution
Loyalty = direct traffic share. Email leaderboard = mail traffic share and mail visits. Attention = duration x total visits.

The next enrichment pass stores 12-month history and 24-hour deltas once enough daily observations exist.
Debate-It verdict
Build the spine first
The wedge is not a pretty leaderboard. The moat is the YC company graph plus recurring traffic, email onboarding capture, and startup-specific agents that convert observations into reusable execution.
Office-Hours QA gate
Trust in four seconds
Every public number carries a source status. TrafficLens rows graduate from baseline to trafficlens only after live enrichment and autoresearch contract checks pass.
Categorization
Industry, founders, revenue
Filters support industry, sub-category, batch year, founding team, revenue state, active status, and location.
Agent factory
One startup, one agent
Each profile can graduate into a public support agent trained on its site, docs, onboarding emails, and competitive position.
