For brands
Our Account Managers handle outreach, negotiation and delivery for brands on the platform.
Kai Stewart is a high-visibility combat sports athlete whose BKFC championship profile gives brands a strong mix of credibility, intensity, and fan engagement. With a proven winner’s story, a loyal fight audience, and a punchy on-camera presence, he’s a natural fit for campaigns looking to connect with action-sports, fitness, and performance-minded consumers.
Currently, I am the BKFC Featherweight World Champion, youngest in promotional history (22). I work hard every single day to represent myself and the brands who endorse me to the best of my ability. I am an active member of the community and give back as a youth/high school wrestling coach. I wake up every day willing to do whatever it takes to achieve my goals, and I’d love to put the same effort into your brands!!

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.
