A brand sprint produces strategic clarity: positioning, messaging, and visual direction, typically in 2–6 weeks. A full rebrand produces the complete execution system: final identity, website, collateral, and all the assets needed to operate the brand externally. A sprint typically feeds into a rebrand — it's the diagnostic phase that determines what the rebrand needs to accomplish. A company that goes straight to a full rebrand without a sprint risks spending 16–20 weeks building on a strategic foundation that was never validated.
