The founders considered the name "Sparrow Systems" before choosing Anthropic.

Judged as of 2026. True: accounts from Anthropic's founders or reliable reporting confirm that 'Sparrow Systems' was a name considered for the company before 'Anthropic' was chosen. Mostly true: it was considered, but a minor detail is off, such as the exact form of the name or who suggested it. Mixed: the name was mentioned only jokingly or in passing, and it is unclear whether it was seriously considered. Mostly false: a similar but different name was considered. False: the evidence shows the name was never considered, for example a co-founder or a documented record of the naming process contradicts it. Daniela Amodei's own remark is weak evidence on its own; corroboration by another founder or by contemporary documents is preferred.

Several independent sources report that "Sparrow Systems" was a name the founders considered before choosing Anthropic. E1 lists it among the names the founders bounced around before Amodei settled on Anthropic. E2 says the company originally planned to call itself "Sparrow Systems," and E3 says the founders first wanted that name, tracing it to a fable by Nick Bostrom. E4 lists the same set of candidate names. None of these sources contradicts the claim.
