The Second Curve

Every business follows an S-curve: slow start, steep growth, peak, then decline. Companies that endure start a second S-curve before the first peaks. Named by Charles Handy in The Empty Raincoat (1994): the optimal start is during late-growth or early-maturity — when the first curve still funds investment but the team can still see the need. The canonical case is…

How it works

Step 1 — Diagnose first-curve position. Classify as: early growth / late growth / early maturity / late maturity / decline. Use revenue growth trend (3 years), gross margin trend, market share trend, TAM penetration. Late-growth and early-maturity are highest-leverage moments for second-curve investment.

Step 2 — Identify candidate second curves. For each candidate: business description, distance from core (1=same customers/product new feature; 3=new customers adjacent product; 5=new customers new product new capabilities), sized opportunity, time to meaningful revenue, investment required. Most second curves should be distance 2-3.

Step 3 — Time the start. Late growth: start now. Early maturity: start now, urgently. Late maturity: start now, constrained funding. Decline: too late internally — consider M&A, exit, or restructure.

When to use it

• user says 'our growth is slowing and we need to figure out what's next', 'we keep doubling down on the core but I'm worried about disruption', 'when is the right time to start something new alongside the main business', 'should we diversify now or wait', 'competitors are moving into adjacent spaces'

Worked example

Intel's 1985 Memory-to-Microprocessor Pivot

The most documented case of second-curve discipline is Intel's exit from memory chips in 1985-1986, recounted by Andy Grove (then president, later CEO) in Only the Paranoid Survive (1996). The case demonstrates both the framework's mechanics and the cognitive failures that nearly prevented it.
