Kesara is the visionary CEO behind BrandFactory, a digital media company powering multiple content platforms that reach millions. When he’s not leading a team of creatives, he’s often geeking out over Marvel and DC universes, decoding Spielberg's directorial magic, or revisiting classics like The Shawshank Redemption, Interstellar, and Pirates of the Caribbean (yes, he's a Johnny Depp loyalist).

INDUSTRY FOCUS
Kesara’s writing and content leadership often focus on the intersection of entrepreneurship, entertainment, and emerging digital cultures. He’s particularly passionate about telling stories that celebrate founders, dissect business blueprints from media narratives, and spark curiosity in audiences across the globe.

FAVORITE MEDIA
A sci-fi enthusiast with a taste for high-stakes storytelling, Kesara’s favorite titles range from cerebral time-space odysseys to charismatic pirate adventures. He thrives in content that mixes real-world business insight with the spectacle of entertainment — think Shark Tank meets Black Mirror, with a touch of Marvel heroics.
