Yo, have you heard about Rob Haber? Dude’s the real deal in the startup scene. Basically, he’s a YC batch S23 guy, and he’s crushing it with not just one, but two YC-backed startups.

Imagine authentic, direct messaging that actually boosts conversions – that’s what Rob and his team are all about. They’re based in NYC, by the way, and he co-founded this with his long-time buddy Alex Luis. They’ve been at it together for a minute, huh?
But Rob’s not just some guy who jumped into startups outta nowhere. Nah, he’s got a legit background in AI – he’s got an MS in AI from Carnegie Mellon, one of the top schools, and he’s worked at big names like Regeneron and Amazon. Plus, he was a Machine Learning Engineer at Scale AI, where he trained those huge language models for enterprise clients. Basically, he knows his way around the tech and data side of things.
And get this – before all the startup hustle, Rob even founded his own beef jerky company. Yeah, he’s got that entrepreneurial spirit in his blood. Always experimenting, always building. That’s what makes him stand out – he’s not just about the tech; he’s about creating real solutions that actually solve problems.
