Deep tech founders face a unique challenge: turning breakthrough science into a scalable startup. From navigating academia and IP to fundraising, manufacturing, and product-market fit, the path from research lab to real-world impact is anything but straightforward.

This week on Build Mode, Isabelle Johannessen sits down with Capella Kerst, founder and CEO of @geCKoMaterials and 2024 Startups Battlefield runner up. geCKo Materials is building a bio-inspired adhesive with applications across robotics, manufacturing, and even space. In this episode, they explore how she turned a Stanford PhD breakthrough into a venture-backed deep tech company.

This conversation covers:
🧩How to turn academic research into a scalable startup
🧩The challenges of moving from Stanford PhD to founder and CEO
🧩What it takes to raise capital as a deep tech and hardware startup
🧩Why commercialization and manufacturing are the hardest parts of innovation
