Synopsis: This episode is proudly sponsored by Quartzy. What happens when engineering discipline, business pragmatism, and breakthrough immunology collide? In this episode of Biotech 2050, host Alok Tayi sits down with Jay Hartenbach, President & COO of Diakonos Oncology, to unpack one of the most unconventional—and promising—approaches in cancer immunotherapy today. Jay traces his journey from biomedical engineering into biotech operations, sharing how Diakonos was built outside the traditional venture playbook and why the company chose to tackle two of the most punishing cancers first: glioblastoma and pancreatic cancer. He reveals how Diakonos’ dual-loading dendritic cell platform creates an exponentially stronger immune response—essentially tricking the body into launching a viral-level attack against cancer. From capital-efficient clinical execution to nontraditional fundraising and early signs of durable patient responses, this conversation offers a rare, behind-the-scenes look at how bold science, disciplined operations, and relentless persistence can reshape what’s possible in oncology.
