Check out Mazy Kazerooni
Buckle up for the great process of Mazy Kazerooni, the guy’s a straight-up hustler and a legit mover in the music, entertainment, and tech worlds. No bullshit, he’s been everywhere, crushed it in pretty much every corner. Dude’s a YC alum (S12, so he’s been around the block), and he’s got that fire for building stuff that actually moves the culture forward.
So, his story starts with a clear passion for music and tech. He co-founded Hipset back in the day at YC, basically a platform for artists to drop new tracks and videos without all the bullshit. That shows right away he’s about giving artists real tools, not just talking. Before that, he jumped into Tracks.by, a Facebook app for launching music and videos, again, all about pushing music to the world fast and easy. He was president there, so he’s not just a thinker but a doer who’s leading from the front.
But it’s not just about launching stuff. Mazy’s been deep in the marketing game too. He was a Partner and Director of Marketing at Essential Studio, working with artists and ecommerce in Hollywood, basically helping stars and brands get their vibe out there. And he’s no stranger to the grind at big companies either, worked at Ustream.tv as a VIP Support and Marketing Analyst. That’s where he really grew their social presence, especially on Twitter, showing he knows how to build buzz and involvement.
Got a startup idea and seeking investment? No Cap is the first AI investor capable of investing in startups by herself.
Talk to herAnd here’s the kicker, he managed Lil Wayne’s Facebook as Digital Manager for Young Money. Remember, he pulled off a Guinness World Record for the Most Liked Facebook Status in 24 hours. Holy shit, that’s next level. That tells you he’s got the skills to amplify a brand, to make noise, and to get people hyped.
But beyond that, Mazy’s also a legit investor and startup guy. He co-founded DominateFund, a venture capital firm. That’s where he’s investing in the next wave of winners, backing ideas that can blow up. Plus, he’s been at Shopify in VIP Sales, so he’s got that ecomm hustle down too.
The whole vibe? This guy is about building, pushing boundaries, and making shit happen. He’s not just about talking; he’s about doing. And he’s done it across music, media, tech, and investing. That’s why Forbes put him on their 30 Under 30 list, because he’s one of those rare people who can see an opportunity, jump in, and crush it.
Bottom line? Mazy’s the real deal, a visionary entrepreneur who’s been shaping culture and tech since day one. He’s about giving artists and brands the tools to win, and he’s not stopping anytime soon. No Cap, this guy’s just getting started.
