Hard Tech War Room: Battle Stories and Game Planning for your product.
Join us in the trenches of building the product.
Learn the design philosophy of translating ambiguous user needs into solid design inputs, hear from startups that survived the battle, and bring out your own technical issues to combat.
This is a technical session for founders, builders, and those with great ideas they want to bring to life.
Join HardTech Miami and leave with a framework to bring your product to life.
Intro: Engineering Design
An overview of the methodology of designing a great product or feature. Walk away with a design framework you can apply to your own product!
Panel: Unfiltered War Stories
Hear from founders that made it through. How did they choose between concepts? When did they know to pivot in their designs?
Hannan Happi, Co-Founder & CEO, Exowatt
Serial hardware founder who's shipped physical products twice—first a Y Combinator-backed VTOL drone (acquired), now modular thermal energy systems. Translated "data centers need reliable clean power" into a 3-in-1 system that's raised $120M+ from a16z, Felicis, and Sam Altman with contracts across the U.S.
Amir Emacha, Co-Founder & CEO, Microhub
Started selling hardware at 18—moved 200,000+ phones across Latin America, then pivoted to software with Nerds Co. Launched Earth Robotics in 2020 targeting robot food delivery, but when buildings said "fix our package chaos first," he pivoted again. Now runs Miami's first Microhub serving 6,000+ units.
Ethan Loosbrock, Founder & CEO, Ouros Energy
Former MIT battery researcher who cut costs 50% while doubling energy density at PolyJoule. At Ouros, he's doing it again—targeting 10x gains with novel cathode chemistry for aerospace applications like eVTOLs. Raised $3M to build their first commercial manufacturing line.
Audit: Technical Game Planning
3 local builders bring their current design predicaments for rapid fire re-engineering with our panel.
