Everything is a Signal

The future rarely announces itself. It emerges as a collection of weak signals that most people overlook.

Success, whether in science, business, or investing, is ultimately an exercise in signal processing: recognizing meaningful patterns, filtering out noise, and connecting ideas that initially appear unrelated.

Few people embody that way of thinking better than Sahir Ali, founder and managing partner of Modi Ventures, my guest on the latest episode of Precision Signals. His career spans engineering, quantitative finance, cancer research, entrepreneurship, and venture capital. Those experiences ultimately shaped BioStack, Modi Ventures’ investment strategy for identifying technologies that create value across the life sciences. Rather than evaluating companies within traditional sector boundaries, BioStack seeks foundational technologies whose impact compounds across multiple layers of the innovation ecosystem.

One story that stayed with me was Sahir’s early investment in the hardware startup Groq. At the time, many questioned why a life sciences-focused investor would back an AI infrastructure company. Through the lens of BioStack, however, the investment was never about chips. It was about recognizing foundational technologies that would eventually reshape biology, drug discovery, and medicine. That conviction proved remarkably prescient, culminating in Nvidia’s landmark multi-billion-dollar transaction centered on Groq’s technology and talent. Long before AI infrastructure became one of the most sought-after assets in technology, BioStack had identified its strategic importance.

The conversation is ultimately less about venture capital than it is about intellectual discipline. How do you distinguish signal from noise? How do you build conviction before consensus forms? How do you recognize that the technologies most likely to transform medicine may emerge from places that, today, seem entirely unrelated to healthcare?

Those questions matter far beyond investing. They matter to anyone trying to understand where science, technology, and society are headed next.

I hope you’ll enjoy the conversation as much as I did.
