Sparkline is a concept identity I designed for a B2B AI analytics platform. A sparkline is a tiny, clear trend line, and a spark is the moment of insight, so I wanted the logo to feel both precise and energetic.

I built the symbol from the letter S, using two mirrored arc forms that read as a letter, a signal and a rhythm at once. In the wordmark, I customized a few letterforms and turned the dot of the "i" into a spark.
