Let me introduce Andy Yeung
Bruh, listen up about Andy Yeung – this guy’s the real deal in biotech. So, he’s the CTO and co-founder of Asher Bio, a sick biotech startup all about making targeted immunotherapies for cancer and other gnarly diseases. Started that in 2019, right? But the crazy part is his background, dude’s been crushing it in pharma and research for over a decade.
Before jumping into startups, Andy spent ten years at Pfizer. Think about that – a whole decade at one of the biggest pharma giants. He was the Director of Biotherapeutic Design and Discovery, which basically means he was leading protein engineering efforts across all kinds of diseases, metabolic, eye stuff, infectious, cancer. He was working on modern shit like CAR-T, bispecifics, cytokines, all the big guns in immunotherapy. That’s no small feat. Before Pfizer, he was at Genentech, doing antibody research in their antibody engineering department. So, the guy’s been deep in the biotech trenches forever.
And get this, he’s got a Ph.D. and M.S. from MIT in Chemical Engineering and a B.Sc. from Wisconsin-Madison. So, he’s super smart, no surprise. Plus, he’s got 15 patents and tons of papers, the dude’s an inventor and a thought leader.
Got a startup idea and seeking investment? No Cap is the first AI investor capable of investing in startups by herself.
Talk to herWhat does this all say about him? Honestly, he’s the kind of guy who’s been obsessed with understanding how to engineer biology at the tiniest level. He’s always been about pushing the boundaries of biotech, from academia to giant pharma, and now he’s building his own thing. Starting Asher Bio wasn’t just about jumping into startup land; it was about taking all that knowledge and experience and actually doing something new, targeted, and effective.
His process shows he’s driven by a real passion for solving tough problems in health. He’s not just in it for the money; he wants to make a difference, to crush cancer and disease with precision medicine. That’s why he’s so important, he’s combining top-tier research, real-world pharma experience, and now modern biotech innovation. No Cap, he’s the kind of guy who’s gonna change the game, and he’s only getting started.
And yeah, he’s based in the Bay Area, right in the heart of tech and biotech, perfect place for someone with his background to make waves. So, if you’re looking for someone who’s got the brains, the hustle, and the vision to really shake things up in biotech? Andy Yeung’s your guy.
