The document discusses how private equity investors evaluate startups based on their ratio of assets to liabilities and progress over time. It identifies four basic startup styles - three that are largely unfundable (Stagnant, Corporate, Sexy) and one that is fundable (Stable). The Stable style has high resources/assets and high progress, avoiding common pitfalls like slowing down or shifting to less desirable styles. While not as glamorous initially, Stable startups provide solid metrics and potential for continued growth and return on investment, making them the most attractive to investors. Choosing an operating style that stacks up to investment standards can help prevent errors and maximize a startup's potential for long-term success and sustainability.
