Haren Chelle is the co-founder and CEO of Pulse (PulseGen Technologies), an AI-native feedback intelligence platform that turns scattered customer signals - support tickets, sales calls, app-store reviews, social chatter - into prioritized product decisions for B2B SaaS teams. An IIT Patna alumnus who spent his earlier career scaling conversational-AI businesses across Asia Pacific at Yellow.ai, he started Pulse in 2024 with two old friends and raised a $1.4M seed round led by Endiya Partners.

Dan Yates
Dan Yates is the CEO and Chairman of Dandelion Energy, the largest residential geothermal company in the United States, a startup spun out of Google X that drills backyard boreholes to heat and cool homes with the steady temperature of the earth. Before geothermal, he co-founded Opower, the energy-efficiency software company he took public in a billion-dollar-plus 2014 IPO and sold to Oracle in 2016. A Harvard computer scientist turned climate operator, Yates describes his own superpower as being 'a terrible loser' and is doggedly betting that 'lukewarm' geothermal becomes a mainstream pillar of the clean-energy transition.

A TED Speaker, Forbes 30 Under 30, and Fortune 40 Under 40 honoree, Prukalpa has raised over $206M and turned a midnight brainstorm about broken streetlights into one of the fastest-growing data governance companies on the planet.
