Episode 38
September 28, 2022
(Conversation Recorded on September 15, 2022.)
On this episode, venture capitalist and entrepreneur Sebastian Heitmann discusses his work in tech innovation towards more sustainable futures. Technology will inherently be a part of any human future - the question is what will this technology be? Sebastian’s work focuses on finding what is termed ‘Gigacorns’ - scalable inventions for low(er) carbon futures. If successful, this could result in large scale reductions in the CO2 emissions for global society.
