What's up with Hari Viswanathan

Honestly, let me school you on Hari Viswanathan, this dude is the real deal in the startup world. He jumped into tech early, coming from Malaysia, and has been all over the place, San Francisco, Bangkok, Singapore, you name it. Dude’s got that global hustle.

He’s a YC W19 alum, so he’s legit in the startup scene. But what really sets him apart is his in-depth analysis into SaaS, enterprise sales, and startups that scale fast. Before all that, he did research and engineering at some heavy hitters like NEC Labs, IBM India Research, Thomson Corporate Research, and InterDigital. Basically, he’s been neck-deep in tech R&D, building the skills and mindset to turn ideas into products.

Then he jumped into the startup game. He’s been at companies like Zenefits (back in W13, so he’s been around the block), ZeroDown, Semantics3, Plate IQ. The guy’s been crushing it in B2B SaaS, especially around hardware, IoT, and e-commerce. He’s super passionate about the future of work, blockchain, and how tech can reshape industries.
