In a market shaped by volatile equity prices, higher interest rates, and tighter scrutiny on private valuations, investors are becoming more selective about how they deploy capital. The focus has shifted from chasing growth at any cost to structuring investments that protect downside while preserving meaningful upside.

One instrument gaining renewed traction among experienced investors is the convertible note. Once associated mainly with early-stage startups, convertible notes have matured into a versatile capital tool used across venture capital, private equity, and structured credit strategies in the United States.

The Rise of Hybrid Capital Structures

At a fundamental level, a convertible note is a debt instrument that can convert into equity upon a future triggering event, such as a qualified financing round, acquisition, or public listing. Until conversion, the investor typically receives interest payments, seniority in the capital stack, and contractual downside protection.

This hybrid structure is precisely what makes convertible notes attractive in uncertain conditions. Investors are no longer forced to choose between the safety of debt and the upside of equity. Convertible notes offer both, when structured correctly.

According to Terry CK Au, Managing Partner at Auset Capital Group, the appeal lies in disciplined underwriting rather than speculation.

“Convertible notes allow investors to participate in growth without committing to fragile early-stage valuations,” Au explains. “You approach the investment as a lender first, while retaining the option to participate in equity upside if execution proves itself.”

Managing Risk in Volatile Investment Markets

One of the most compelling advantages of convertible notes is their position within the capital structure. As debt instruments, they generally sit senior to common equity, which provides greater protection if a business underperforms or enters distress.

At the same time, conversion mechanisms such as valuation caps, conversion discounts, or equity kickers allow investors to benefit when companies scale successfully. This asymmetric return profile has become increasingly important as private-market investors recalibrate risk expectations following years of inflated valuations.

“In uncertain markets, protecting capital is just as important as generating returns,” Au notes. “Convertible notes give investors yield today while preserving flexibility for tomorrow.”

This combination of yield, seniority, and optionality makes convertibles particularly attractive during periods of economic transition.

Alignment Between Investors and Founders

Beyond risk management, convertible notes can also improve alignment between investors and operators. Traditional equity financings often require early valuation negotiations, which can slow deals and create friction—especially when future performance is still uncertain.

Convertible notes defer that valuation decision. Founders gain time to execute and demonstrate traction, while investors secure protective terms that reflect real operational risk.

“When structured properly, convertibles create alignment rather than tension,” says Au. “Founders aren’t forced into premature pricing, and investors are compensated for the uncertainty they’re underwriting.”

This flexibility often results in faster capital deployment and healthier long-term partnerships.

Expanding Beyond Venture Capital

While convertible notes remain common in venture and growth-stage investing, their use has expanded well beyond startups. Today, they are increasingly applied in private credit, real estate development, infrastructure projects, and cash-flow-generating operating businesses.

In these contexts, convertible notes may include features such as revenue participation, performance-based conversion terms, or structured exit provisions. This adaptability allows investors to tailor risk and return profiles to specific business models rather than relying on one-size-fits-all equity structures.

“The biggest misconception is that convertibles are only for startups,” Au explains. “They are just as effective in mature businesses with assets, cash flow, or defined exit paths.”

Convertible Notes as a Core Portfolio Tool

As private markets evolve, investors are demanding better alignment, stronger downside protection, and clearer paths to value creation. Convertible notes are increasingly viewed not as niche instruments, but as foundational tools within sophisticated investment portfolios.

For investors willing to underwrite structural complexity in exchange for improved risk-adjusted returns, convertible notes offer a disciplined way to stay invested without overcommitting to uncertain valuations.

In an investment environment where patience and structure matter more than speed, convertible notes have become a practical solution for navigating uncertainty while maintaining long-term opportunity.
