The time for a new company to challenge an incumbent has compressed dramatically. As private market timelines extend, many unicorns that haven't gone public are already being 'eaten away' by the next wave of startups, creating a significant liquidity challenge for their late-stage investors.

Data from 25 years of venture capital shows that of 100,000+ startups, only ~450 exited for over $1B—a 0.45% success rate. This makes a unicorn outcome ten times rarer than gaining admission to Harvard (~4% acceptance rate), highlighting the statistical risk of unicorn-only investment strategies.

The biggest venture outcomes often take 8-10 years or more to mature. Instead of optimizing for quick IRR, early-stage VCs should embrace long holding periods. This "duration" is a feature that allows for massive value creation and aligns with building truly transformative companies, prioritizing multiples over short-term gains.

Contrary to the instinct to sell a big winner, top fund managers often hold onto their best-performing companies. The initial 10x return is a strong signal of a best-in-class product, team, and market, indicating potential for continued exponential growth rather than a peak.

An explosion of billion-dollar valuations has created more unicorns than the pool of strategic buyers can support. This problem is worse for AI startups, whose massive valuations often exceed those of the legacy players they disrupt, making acquisition by their most logical buyers impossible and forcing a reliance on a tight IPO market.

Despite perceptions of quick wealth, venture capital is a long-term game. Investors can face periods of 10 years or more without receiving any cash distributions (carry) from their funds. This illiquidity and delayed gratification stand in stark contrast to the more immediate payouts seen in public markets or big tech compensation.

Despite headlines about rapid-growth companies, the typical startup journey is slowing dramatically. The median time between Series A and B rounds is now close to 1,000 days (almost 3 years), creating a barbell market where a few companies raise quickly while the majority face a much longer path to their next milestone.

The trend of keeping startups private longer means a company founded 10 years ago, like Airtable, can become technologically obsolete before it exits. The underlying platform shift (e.g., from no-code to generative AI) can strand even successful companies.

Founders Fund's investment in SpaceX is cited as one of the best ever, largely because they held the position for over a decade. This contrasts with the common VC practice of distributing shares at IPO, demonstrating that true generational returns come from long-term conviction, not quick exits.
