SegmentStream is a SaaS platform for marketing analytics and performance measurement. It helps marketing teams see which campaigns actually drive revenue — through cross-channel attribution, incrementality testing, budget optimization, and lead scoring.

As the product grew, its visual identity needed to grow with it. We refreshed SegmentStream's key visual style to give the brand a deeper, more premium, and more confident look.

On that foundation, we built a page design system made to scale with the product — layouts for every screen size, ready for developers, covering more than ten pages: product features, solutions, pricing, case studies, and more.

Marketing analytics is a technical subject, so illustration became part of the system itself, not decoration on top of it. We built a repeatable illustration language that breaks down complex mechanics — like attribution and incrementality testing — into simple, step-by-step visuals anyone can follow.
