Sebastian Heitmann: “Gigacorns”
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.
