Stock Bottlenecks
Every public company depends on other companies to function - suppliers it can't easily replace, and customers that make up an outsized share of its revenue. This section breaks that down for one stock at a time, with two pie charts per stock: supply-chain dependency and customer concentration.
New stock pages are added roughly one per day.
Bottleneck Leaderboard
How many times each company has shown up as a bottleneck - supplier or customer - across every stock page built so far.
A company that keeps showing up here isn't just important to one stock - it's a shared dependency across many of them. If a name high on this list runs into trouble - an outage, a shortage, a regulatory action, a bad quarter - the disruption can ripple across every business that relies on it, not just the one you started on. The higher the count, the more concentrated - and systemic - that risk becomes.
