Funding rounds, debt and other financing events.
A firsthand founder interview confirms initial $25M funding from Benchmark, without its financing date or series designation. The separately cited March 27, 2024 press account reports Series A and additional participants; that is publication, not proven settlement. Retained as non-additive context for the initial round, not another $25M raise; exact instrument/date/identity linkage remains unverified. The $1.582B confirmed-primary subset includes that initial amount plus the issuer's $52M B and $1.505B D, not lifetime funding. The $250M C mixes primary and secondary without an allocation and is excluded. May 2026 growth-equity remains uncorroborated and potentially overlapping. No current register, exact subscribing funds/classes, independently reviewed complete history or source-rights approval is established.

Included in Initial Benchmark funding; not added again to the confirmed-raised sum.
Reported classification and participants only. March 27 is this account's publication, not an authenticated close.

Eric Vishria's stated board role is not a personal investment; unspecified executives are not named subscribers. Exact funds, allocations, classes and current holdings remain unknown.
Benchmark
Source published Aug 20, 2024; not a financing date
The firsthand founder transcript establishes initial $25M funding from Benchmark; it does not specify the financing day, series, exact fund, instrument terms or a lead role. August 20 is interview publication, not investment timing. The separate reported Series A roster is not upgraded to founder-confirmed participants. No additional early seed is inferred from databases, a valuation ratio or subtracting cumulative totals. No current equity balance or willingness to sell is established.
These database claims have not been independently verified and are excluded from the sourced-event count.
Investor participation not independently verified
No issuer amount, terms or independently corroborated May 2026 financing located; do not infer this is separate from Series D.
