So.... this is about a pay-subscription search engine called 'Kagi' out of Palo Alto, founded 2018.

Made me think and have to do some digging for the 'Kagi' out of Berkeley founded in the 90s where you could register your shareware purchases in the days before PayPal. Which seems to have been largely scrubbed from history outside of some WayBack snapshots.
