Goodfire
Goodfire matters as a model-understanding company rather than another application wrapper, turning interpretability research into usable infrastructure.
Capital & commercial trajectory
Funding rounds and reported revenue
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.
Valuation, debt or credit, acquisition value, and market cap remain distinct records below and are not combined with funding or revenue.
A structured financial history has not been completed for Goodfire.
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.
Current reported signal: Announced a $150M Series B at a $1.25B valuation in February 2026.
