Unlike pure software, freight logistics involves complex physical realities that tech-first founders consistently underestimate, leading to massive failures. Successful ventures in this space almost universally have a founder who deeply understands the industry's nuances from direct experience.

A common failure mode for well-funded biotechs is growing headcount too rapidly. Immunocore's CEO advises new leaders to pace themselves, emphasizing that drug development is a marathon. Prematurely scaling creates fixed expenses that can drain capital before key scientific milestones are hit.

The transition from a resource-rich environment like Novartis to an early-stage biotech reveals a stark contrast.

This 'patient first' approach helps uncover unmet needs in their treatment journey, providing a more powerful and differentiated perspective than focusing solely on the scientific or commercial landscape.

Unlike software startups that can "fail fast" and pivot cheaply, a single biotech clinical program costs tens of millions. This high cost of failure means the industry values experienced founders who have learned from past mistakes, a direct contrast to Silicon Valley's youth-centric culture.

A biotech investor's role mirrors that of a record producer by identifying brilliant talent (scientists) who may lack commercial experience. The investor provides the capital, structure, and guidance needed to translate raw scientific innovation into a commercially successful product.

Raising venture capital is often a network-driven game. If you don't already have a network of VCs or a clear path through an accelerator, your focus should not be on fundraising.

A frequent conflict arises between cautious VCs who advise raising excess capital and optimistic founders who underestimate their needs. This misalignment often leads to companies running out of money, a preventable failure mode that veteran VCs have seen repeat for decades, especially when capital is tight.

John Maraganore's transition from science to business wasn't a choice but a reluctant career change forced upon him by Biogen's CEO.
