Ultra-late-stage companies like Ramp and Stripe represent a new category: "private as public." They could be public but choose not to be. Investors should expect returns similar to mid-cap public stocks (e.g., 30-40% YoY), not the 2-3x multiples of traditional venture rounds. The asset class is different, so the return profile must be too.

Waterbridge's model, with high margins, strong organic growth, and long-term contracts, more closely resembles a hazardous waste company than a midstream energy firm. Analysts argue it deserves a valuation multiple in line with waste players (14-18x EBITDA) versus lower multiples for gathering and processing peers (9x EBITDA).

Amphenol runs as a federation of autonomous business units. This structure is key to its M&A success, as acquired companies retain their brand, culture, and customer intimacy. Sellers prefer Amphenol because they know their business won't be suffocated by a monolithic corporate hierarchy.

To prevent the next generation of leaders from being burdened by debt, WCM's founders transfer their ownership stakes at book value—not market value. This massive personal financial sacrifice is designed to ensure the firm's long-term health and stability over founder enrichment.

In a world of commoditized capital, offering a full suite of solutions creates a competitive advantage. By providing fund investments, co-investments, secondary liquidity, and portfolio company debt, a firm becomes an indispensable strategic partner to PE sponsors, generating proprietary and superior deal flow.

The most lucrative exit for a startup is often not an IPO, but an M&A deal within an oligopolistic industry. When 3-4 major players exist, they can be forced into an irrational bidding war driven by the fear of a competitor acquiring the asset, leading to outcomes that are even better than going public.

Amadeus was formed by major airlines to create a neutral distribution system. This origin story provided immediate scale, credibility, and deep industry integration, creating a powerful competitive moat from day one that would be nearly impossible for a startup to replicate.

The venture capital paradigm has inverted. Historically, private companies traded at an "illiquidity discount" to their public counterparts. Now, for elite companies, there is an "access premium" where investors pay more for private shares due to scarcity and hype. This makes staying private longer more attractive.

Beyond financial incentives or strategic differences, a primary driver for a successful partner to spin out from an established firm can be pure ego. The desire to build something independently and prove one's own success is a powerful, albeit rarely admitted, motivation for starting a new venture.
