What is a ‘cliff edge’ for a startup?
Cliff edge is operator slang for the point at which a startup will run out of cash if no new capital arrives — the moment of binary outcome (raise or die). Cliff-edge planning is a core CFO/founder discipline: track burn, runway and cash on hand against milestones to ensure the company never approaches the cliff without options.
Reaching cliff edge without a closed round triggers severe consequences: layoffs, asset sales, fire-sale acquisitions or insolvency. Sophisticated founders raise at the ‘low’ point of runway (typically 6 months) rather than at the cliff to preserve negotiation leverage.
