After a fatal accident with its own AV program, Uber pivoted. Instead of building cars, its long-term strategy is to be the essential demand-generation platform for every AV manufacturer, aiming to maximize the utilization and revenue of any "box with wheels" from any company.

Unlike in private equity, an early-stage venture investment is a bet on the founder. If an early advisor, IP holder, or previous investor holds significant control, it creates friction and hinders the CEO's ability to execute. QED's experience shows that these situations are untenable and should be avoided.

Echoing the Hippocratic Oath, a venture investor's primary job with a high-performing company is to stay out of the way and not disrupt its momentum. While providing resources for talent, capital, and strategy is valuable, it's secondary to the core principle of not interfering with a team that is already executing successfully.

The best tech investments for non-specialists are often disguised consumer companies that use technology for scale, not for core R&D. Uber is a logistics business and Reddit is an ad business. This simplifies analysis away from complex technology to understandable consumer behavior.

While many see autonomous vehicles as a threat to Uber's ride-hailing, its delivery segment may be more important and defensible. Automating last-mile delivery of goods from varied locations is significantly more complex and less economical than automating passenger transport, providing a durable moat.

Dara Khosrowshahi argues that entrepreneurs over-index on Total Addressable Market (TAM), which he sees mainly as a fundraising tool. The real focus should be on proving product-market fit and solid unit economics in a small, defensible niche. Once that's established, you can expand into adjacent markets.

While massive "kingmaking" funding rounds can accelerate growth, they don't guarantee victory. A superior product can still triumph over a capital-rich but less-efficient competitor, as seen in the DoorDash vs. Uber Eats battle. Capital can create inefficiency and unforced errors.

Dara Khosrowshahi manages Uber's position with a dual identity. Internally, he cultivates a startup culture where everyone feels like an underdog fighting for survival. Externally, with regulators and partners, the company acknowledges its scale and embraces the responsibilities that come with it.

An investor's power over a portfolio company is fundamentally limited and primarily negative. While a VC can block a founder's actions, such as through board approval or withholding capital, they cannot force a founder to take a specific path, even if it seems obviously correct. The role is to advise and assist, not to command or execute.
