Where Climate Deep Tech Founders, Funders and Industry come together
What if the next era of ClimateTech isn’t about scarcity, but abundance?
Abundance is redefining the future of climate and industry.
For this year’s HackSummit, we’ll shift the conversation from reductionary approaches, and instead explore plentiness, and the new ways of manufacturing and adapting to a world that continues to grow.
Expect honest (and potentially heated) discussions on topics including, on-shore manufacturing, increased energy demand, post industrial food systems, supply chain resilience, automation, climate adaptation, weather modification and Climate Tech’s role in defense and sovereignty.
Come join 500 Stealth to Series B Founders, strategic investors, corporates, banks, and asset managers looking for their next collaboration in a world of abundance this December 10-11th at Newlab.
