Colby Mefford is a Cal swimmer at the University of California, Berkeley with a strong collegiate sports presence and an authentic athlete-first audience. He’s a strong fit for brands that want to reach performance-minded fans around training, competition, fitness, travel, and the everyday lifestyle of a high-level student-athlete.
I am a persistent athlete that likes to stay active in my time off. I enjoy slack-lining, spikeball, basketball, volleyball, and many things active. Some of my hobbies include learning electric guitar, watching anime, and cooking. Sponsoring me would benefit you because I can reach key demographics of people who enjoy all the things I do.

How do you measure influencer marketing ROI when half the numbers social media gives you are vanity metrics? It is the question brands ask us most, and it came up again when I joined Massimo Marinelli on the Berkida Ventures Podcast.
