Stripe setup a public-facing view of their impact over the Black Friday weekend -- they've supported $10.2B in transactions over 3 days (with a likelihood of reaching $15B before Monday is over).
They handled 30,000 transactions a MINUTE with full reliability, and took perhaps ~$30M in revenue for Stripe once the weekend is over (the vast majority of startups dream of, and fail to hit, that revenue on an annual basis)
Patrick Collison stated that the aggregate revenue of businesses running on Stripe = 1% of Global GDP.
^Those are the kind of figures you almost always find in an ambitious 1st time founders pitch deck, and almost never in a real business' measurable impact.
