Botha describes venture returns as a power law: in a typical fund, many investments fail or produce modest returns, while roughly five to eight tenfold outcomes drive performance and a few can compound to far larger multiples. In Sequoia's history, five to fifteen percent of investments account for more than eighty percent of returns. A team operating in that distribution must preserve the confidence to take rational outlier bets. Sequoia stopped requiring heavy sponsor-written post-mortems because the ritual encouraged fear, while retaining lightweight reviews of lessons such as choosing the wrong team or go-to-market capability. Senior partners support colleagues after losses, and later successes put individual write-offs back into mathematical perspective. The culture remains accountable: a stream of failures without sufficient wins still demands a change.
Origin
Botha connected Sequoia's return distribution with the firm's decision to replace punitive investment post-mortems with lighter learning and stronger partner support.
Core principles
- 01A small minority of outcomes can generate most portfolio returns
- 02The upside magnitude matters more than a simple win-loss ratio
- 03Punitive failure reviews can suppress rational risk-taking
- 04Teams should learn from losses without making the sponsor unsafe
- 05One major success can mathematically absorb several complete losses
How to run it
- 1
Verify the asymmetry
Measure whether a small number of successes truly account for most returns and whether individual downside is bounded. Do not invoke a power law as a slogan.
Pro tip Review both the percentage of winning cases and the magnitude of the largest outcomes.
Watch out The framework is dangerous when one loss can destroy the organization.
- 2
Normalize expected losses
Tell decision-makers in advance that rational bets can fail completely. Distinguish a bad outcome from a decision that was indefensible on the evidence available.
Pro tip Use portfolio math to show how a major winner relates to several bounded failures.
Watch out Normalization must not become indifference to decision quality.
- 3
Keep reviews lightweight
Extract transferable lessons from failed cases without turning the sponsor's memo into a punishment. Focus on a few causes that can improve future choices.
Pro tip Ask whether the space, team, value chain, technology, or go-to-market choice was wrong.
Watch out Eliminating punitive reviews does not mean eliminating learning.
- 4
Restore decision confidence
Have experienced colleagues support a person after a defensible loss so fear does not push every later choice toward the mean. Preserve team membership and psychological safety.
Pro tip Quiet personal support can matter as much as formal reassurance.
Watch out Safety without honest performance feedback can shelter persistent poor judgment.
- 5
Audit the portfolio
Check that outlier successes still occur often enough to carry the losses. If the portfolio produces only failures or modest outcomes, change the process or the people.
Pro tip Judge the system over a portfolio and suitable time horizon, not one isolated result.
Watch out Do not use a future hypothetical winner to excuse an indefinitely failing strategy.
In the wild
Botha cried in a partner meeting after his first investment went to zero, a complete $10 million write-off. Senior partners who had experienced losses supported him because becoming overly careful would make future outlier investing impossible.
→ He retained enough confidence to keep investing rather than recoiling permanently from risk.
Botha explains that an investment returning $500 million can absorb several failed $5 million investments many times over. The comparison does not erase lessons from the losses; it restores the correct scale for judging them inside an asymmetric portfolio.
→ Individual write-offs become tolerable when the portfolio continues to produce genuine outlier wins.
Common mistakes
Punishing every failed sponsor
Heavy post-mortems can teach investors that taking a rational chance threatens their standing, pushing decisions toward safe averages.
Ignoring repeated poor performance
Botha explicitly distinguishes expected portfolio losses from making only unsuccessful investments without enough good outcomes to survive.
Counting wins instead of magnitude
In an asymmetric portfolio, the scale of the few winners matters more than whether a simple majority of investments rose or fell.
Is it for you?
Best for
It is best for venture investing and innovation portfolios with bounded downside and genuinely asymmetric upside.
Not ideal for
It is not ideal where losses are catastrophic, upside is capped, or repeated failure reflects poor process rather than portfolio mathematics.
From the transcript
“between 5 and 15 of the investments we make account for over 80 of the returns”
“we stopped doing post-mortems we and we supported each other”
“learn from it don't dismiss it but you just rationally have to look at the math and go okay next”
