Who I am

I’m Charles Annis, a business analyst, marketer, and founder with a fascination for what happens when creativity meets data. I earned my Master’s in Business Analytics from Cal Poly in 2025, where I developed a foundation in analytics, business intelligence, and data-driven problem solving. Since then, I’ve been putting that thinking into practice through Charles Annis Marketing, where I build partnerships, develop content strategies, and use performance data to turn ideas into measurable results.

I’ve always been drawn to the space between numbers and intuition… finding the signal in the noise, asking better questions, and figuring out what the data is really trying to say. Whether I’m analyzing business performance, developing a marketing strategy, or building something from the ground up, I like getting close to the problem and finding a way through it.

This site is a collection of that work: analytics, marketing, strategy, and a few things that simply caught my interest along the way. I’m currently open to full-time opportunities across business analytics, data analytics, business intelligence, and marketing, while continuing to build, experiment, and see where the next idea takes me.
