Each point matches a dated itemized record below. Funding points show the disclosed amount for that round, not a running total. Revenue remains a separate series and may represent ARR or run-rate rather than audited revenue.

A structured financial history has not been completed for Cartesia.
The profile will not manufacture a chart from incomplete or unsourced figures. Funding rounds, valuation events, debt facilities, and reported revenue must be dated and linked to a public source first.
