Founder's Guide to Capital Formation

An overview of equity, debt, and hybrid structures - when each is appropriate, and how to sequence rounds without foreclosing later options.

The instrument follows the intent

Capital is not a monolith. Equity, debt, and hybrid instruments each carry a different set of expectations, obligations, and consequences. The right instrument is the one that matches the actual work the capital is meant to do - not the one that is easiest to raise.

The right instrument is the one that matches the actual work the capital is meant to do.

Equity, plainly

Equity is patient, permanent, and expensive in the long run. It is appropriate when the business is compounding, the outcome is uncertain, and the capital is funding discovery rather than execution. It is inappropriate when the business is predictable enough to service debt without strain.

Debt, plainly

Debt is disciplined, temporary, and cheap in the long run - provided the business can service it through any reasonable downside. It is appropriate for working capital, receivables, and assets with durable resale value. It is inappropriate for uncertainty.

Hybrids and their tradeoffs

Convertible notes, SAFEs, revenue-based financing, and structured preferred each solve a specific problem - and each introduces a specific complication in the next round. Use them when the problem is real; avoid them as a substitute for a real conversation about valuation.

Sequencing the raise

The first round sets the vocabulary for every round that follows. Cap tables compound. Preferences stack. A clean, well-sequenced early round is worth more than a larger, more expensive one.
