They talk about Guardant’s path from liquid biopsy to early cancer detection, the difficult realities of building a diagnostics company, and why business model innovation can matter just as much as technical breakthroughs. Helmy also explains how AI is helping Guardant make better use of its growing dataset and why he believes the same blood test infrastructure could eventually be used to detect hundreds or even thousands of diseases.
