Key Takeaways

  • Private market investors often regret selling winning public equities too early; David Sacks called his sale of Palantir stock in the $20s a "huge mistake."
  • Taking a board seat can severely restrict liquidity, forcing investors to hold shares longer than desired, a lesson Sacks learned from his experience with Upstart.
  • Old valuation benchmarks are obsolete: a decade ago, Sacks believed a $100 billion market cap was a ceiling for companies like Facebook, but today multi-trillion dollar firms are common.
  • The perception that immense size limits upside is often wrong; Sacks argues a company like Nvidia, currently valued in the multi-trillions, could still be undervalued given its dominant position.

The Cost of Early Exits: Palantir and Upstart's Hard Lessons

David Sacks, a veteran private market investor, confessed that one of the most "vexing questions" in his world is when to distribute public equities. It is, he says, an art he's far from mastering, despite the popular "let your winners ride" mantra often heard on the All-In podcast. His candid reflection offers a sharp counterpoint to any founder who thinks they have this figured out.

Sacks laid out two significant, costly errors. “We were private investors in Palantir,” Sacks explained. “And I think we sold all our stock in the 20s. Huge mistake.” That decision meant missing out on a run that saw Palantir shares climb far higher. He recounted a similar experience with Upstart, where his firm had led the B round. This time, the problem wasn't just timing, but structural. “That was one I think we learned not to go on boards anymore because it restricts your ability to be liquid,” Sacks said. Board seats, while offering influence, can lock up an investor's ability to sell shares, forcing them to watch market movements from the sidelines, unable to act on their own conviction. For founders planning their cap table and future board composition, Sacks' regret is a stark warning about the unseen costs of investor involvement.

Re-evaluating "Ceilings": Why $5 Trillion Isn't the Top

A decade ago, the idea of a multi-trillion dollar company felt like science fiction. Sacks himself admitted to this mindset, recalling how investor thinking was constrained. “So back in those days, 10 years ago, we thought a hundred billion dollar market cap company was pretty much as big as anything could get,” he reflected. For a company like Facebook, then trading around $50 billion, the perceived upside was limited to $100 billion. This ceiling, Sacks now notes, has been utterly shattered. “Things are just totally different now. We have multi-trillion dollar companies. The market's so much bigger.”

This shift isn't just a historical observation; it has immediate implications for how founders and investors evaluate today's market giants. Sacks cited Nvidia as a prime example, a company currently valued in the multi-trillions. Conventional wisdom might suggest a company of that size has little room to grow. Yet, Sacks forcefully pushed back, arguing that such a viewpoint is flawed. He described how “people feel like it's sort of a ceiling on” Nvidia's valuation due to its immense size, but he believes this thinking is misguided. “I think we'll look back at some point in time and say that was a foolish way to think about Nvidia given its dominant position and its valuation relative to earnings over the next two or three years.” For the ambitious founder, this insight suggests that the potential of market-dominant players, even at staggering scales, might be far greater than traditional benchmarks imply. Your perceived "ceiling" for your own market could be dramatically low.

What to Do With This

First, re-evaluate any internal "market cap ceiling" assumptions for your industry; the benchmarks from 5-10 years ago are obsolete. Second, think twice about taking or giving board seats that impose liquidity restrictions, especially for investors whose primary interest is capital appreciation – Sacks' experience with Upstart shows the constraint can be costly.
