How do you rebrand at Series C without losing brand equity?

Start with an equity audit — map what the company actually owns in the market before deciding what to change. Every Series C rebrand has elements worth carrying forward deliberately: customer associations, visual signals, positioning claims that have genuine market recognition. The agencies that do this well distinguish between what's limiting the brand (which needs to change) and what's built up over time (which is worth preserving). A rebrand that throws everything away and starts from scratch loses that equity. A rebrand that only changes the surface without addressing the strategic limitations doesn't actually solve the problem.
