📋 Summary

The Intersection of Science, Investment, and Human Health

In this episode of Invest Like the Best, host Patrick O'Shaughnessy sits down with Tal Zacks, a physician-scientist, former Chief Medical Officer at Moderna, and current investor at Orbimed. The conversation explores the complex, high-stakes world of biotechnology, the lessons learned from the rapid development of mRNA vaccines, and the future of how we manage human health.

The Philosophy of Investment in Biotech

Zacks emphasizes that biotech investing is distinct from traditional tech venture capital. Unlike software, where success can be achieved through rapid iteration and massive scaling, biotech is constrained by the unpredictability of biology and pharmacology. Zacks argues that a successful investment requires a "collaborative venture capital" approach—where investors do not just deploy capital, but actively leverage their domain expertise to help management teams navigate the "long, non-linear" path of drug development.

He stresses that the "atomic unit" of a biotech investment is a thesis that must be proven. Investors must balance the financial requirements against the probability of scientific success. As Zacks notes, "I'm not going to be making investments in fields that I know zero about," highlighting that the best investors are those who can ask the right questions and build syndicates of experts who bring complementary perspectives to the board table.

Moderna and the mRNA Platform

Reflecting on his time at Moderna, Zacks describes the company’s success not as a stroke of luck, but as the result of a deliberate, platform-driven strategy. By focusing on the "engineering potential" of mRNA, Moderna was able to treat the drug as a piece of software. "Once you get the first one right, the marginal cost for the next one is a fraction," Zacks explains. This platform approach allowed the company to be prepared for the COVID-19 pandemic, having already successfully tested mRNA-based neutralizing antibodies against eight other viruses.

Zacks provides a nuanced post-mortem of the COVID vaccine rollout. While he stands by the safety profile of the vaccines—calling them "the most well-studied medical intervention in the history of mankind"—he acknowledges a failure in the public square. He admits that scientists may have overstepped by assuming that "science in itself and reason will be an ethical force for good." He argues that the medical community must respect the public's need to weigh moral and ethical frameworks, rather than simply dictating policy.

The Future: From Sick Care to Healthcare

Zacks is optimistic about the next 20 to 30 years, predicting a shift from a reactive "sick care" system to a proactive model of promoting health. He notes that while current diagnostic tools are "incredibly crude" and rely on the same panels used 40 years ago, artificial intelligence is beginning to change the landscape. By using AI to understand the variance in individual health data, physicians will be able to identify abnormalities much sooner.

However, he remains a "practical realist" regarding the speed of this transition. He points out that while technology exists to digitize pathology and improve diagnostic accuracy, the economic incentives are often misaligned. "Who's going to pay for changing all those microscopes to be digital?" he asks. This highlights a recurring theme in the discussion: for innovation to reach the public, there must be a viable return on investment that incentivizes the necessary infrastructure changes.

Conclusion: The Human Element

Ultimately, Zacks believes that despite the power of AI and advanced therapeutics, the future of medicine will remain "messy" and human-centric. He warns against a purely utilitarian approach to health, which he suggests would be "dictatorial" and ultimately unacceptable in a democratic society. For Zacks, the most important driver of success remains the people—the "sweat equity" of teams who are willing to dedicate their time and talent to solving the most profound challenges of human health. He concludes that by paying forward the mentorship he received, particularly from his early work with scientists like Steve Rosenberg, the industry can continue to foster the next generation of innovators.

This year's presenting sponsor for Invest Like the Best is Ramp.
Ramp has built a command and control system for companies' finances.
You can issue cards, manage approvals, make vendor payments of all kinds, and even automate closing your books all in one place.
We did an incredibly deep dive on the company and its product as part of this new partnership, and what we heard and saw in customer surveys over and over again was that Ramp is the best product by far.
We've been users ourselves since I started my business, since long before I was able to spend so much time with the founders of Ramp and their team.
Over the holiday, I was with Ramp's founders.
