Fieldset is a self-initiated SaaS brand concept built around a single question: how does a software brand stay coherent when most people meet it inside the product rather than on the marketing site? I developed the positioning, visual identity, marketing web experience, product UI direction, and motion language as one connected system. The work shows how brand and interface can share the same rules, the same type scale, color logic, and spacing, so the promise made on the homepage is the one the product keeps.
