Summary

In our latest episode, we sit down with Dr. John Maraganore, the legendary Founding CEO of Alnylam Pharmaceuticals and one of the most influential voices in modern therapeutics. Raised in a Greek immigrant family in Chicago, John’s journey is a rare blend of scientific obsession, business acumen, and relentless optimism. We cover his whole career journey. From his early days at Biogen, where he invented the anticoagulant bivalirudin (Angiomax), to taking a leap of faith on RNA interference when few believed it could work.

He opens up about being “thrust” from the lab into the business battlefield, the serendipitous experiments that changed his career, and the near-misses that almost stopped him in his tracks. We dive into how he built Alnylam from a small startup into a company with multiple approved drugs for devastating rare diseases like TTR amyloidosis, and the leadership philosophies that kept him and his team moving forward. Along the way, John shares candid lessons for today’s founders.

Whether you’re a scientist, entrepreneur, or just someone who loves stories of grit and discovery, this conversation will inspire you. Don’t miss out on this deep dive into innovation, failure, and the future of medicine.
