SEC rows are Form D filings, where the amount is what was actually sold and amendments update a round rather than adding one. Press rows are split between company-issued releases or wires and editorial or third-party coverage. The total is therefore a floor: a round nobody reported is a round we cannot see. A buyout or control change appears in the timeline but is never added to the total: that money goes to shareholders, not into the company.

Form D is the notice a company files with the SEC when it sells securities without registering them. It reports the amount sold, not a valuation. Figures here are what the filing says. Where a filing is silent, the field is left blank rather than estimated. “Total raised” adds press-reported rounds that never appear in a filing, so it is a floor rather than an audited sum: press amounts are the figures the company announced, and a round nobody reported is a round we cannot see.
