The Middle Math: 60% Probability of Total Capital Loss

Middle-market SaaS companies face brutal probability distributions. Understanding this math is essential for portfolio construction.

The Probability Distribution

The Broken Risk/Reward

Investing in the middle means betting on the 15% that successfully migrate to Ceiling — while paying middle-market valuations.

You’re taking Floor-level risk (60%+ probability of total loss) for Ceiling-level prices. The risk/reward is structurally broken.

Why This Math Is Unforgiving

• The 60% that die often consume 2-3 additional funding rounds before failing
• The 20% that drop to Floor rarely return capital — they become small, unprofitable businesses
• The 15% that rise need exceptional execution AND favorable market conditions
• The 5% zombies trap capital for years with no liquidity path

The structural reality: There is no optionality premium for the middle. There is only risk.
