Michael Heltzen, CEO of Exozymes, joins Grow Everything to explain how cell free biomanufacturing is opening new possibilities for natural products, nutraceuticals, and medicines. Michael shares why engineered enzymes can make high purity molecules without relying on living cells, how Exozymes moved its NCT program from discovery toward commercial manufacturing in less than two years, and why its capital light partnership model is central to scaling impact. The conversation also explores AI guided enzyme design, digital twins for manufacturing, rare cannabinoids, downstream processing, and the disciplined focus required to turn a broad biotechnology platform into real products.

Grow Everything brings the bioeconomy to life. Hosts Karl Schmieder and Erum Azeez Khan share stories and speak with the leaders and innovators using biology to change the world. Biology is the world’s oldest technology, and it can be engineered. So, what are we growing?
