The biggest risk for a late-stage private company is a growth slowdown. This forces a valuation model shift from a high multiple on future growth to a much lower multiple on current cash flow—a painful transition when you can't exit to the public markets.

Traditional valuation models assume growth decays over time. However, when a company at scale, like Databricks, begins to reaccelerate, it defies these models. This rare phenomenon signals an expanding market or competitive advantage, justifying massive valuation premiums that seem disconnected from public comps.

A decade ago, 88% of a tech company's value was created post-IPO. For recent IPOs, 55% of the market cap creation happened while the company was still private, fundamentally changing where investors capture growth.

The venue for tech value creation has dramatically shifted from public to private markets. For recent IPOs, over half of their market cap was generated while private, a stark reversal from ten years prior when 88% of value was created post-IPO.

The quality of public small-cap companies, measured by Return on Invested Capital (ROIC), has plummeted from 7.5% to 3% over 30 years. This degradation means high-growth opportunities now predominantly exist in the later-stage private markets. Institutional investors must shift their asset allocation to venture and growth equity, which has become "the big leagues," not a bespoke asset class.

Private market valuations are benchmarked against public multiples. Currently, public SaaS firms with 30% growth trade at 15-20x revenue, twice the historical average. If this 'bedrock price' reverts to its 7-8x mean, it will trigger a cascade of valuation drops across the private markets.

Financial models struggle to project sustained high growth rates (>30% YoY). Analysts naturally revert to the mean, causing them to undervalue companies that defy this and maintain high growth for years, creating an opportunity for investors who spot this persistence.

Public market investors often build financial models that automatically taper down high growth rates (e.g., 60% to 50% to 40%). This systemic underestimation creates an arbitrage opportunity for private investors who can better value sustained hyper-growth over a longer time horizon.

The market for hyper-growth tech companies now exists almost exclusively in private markets, with only 5% of public software firms growing over 25%. With companies staying private for 14+ years, public markets are now for mature, slower-growing businesses.
