Capital Allocation
What gets funded — and at what ratio — determines what the business becomes.
The 70/20/10 Frame
Google's reinvestment structure remains the clearest public model for balancing risk and return across a portfolio of bets.
- 70% — Core — The proven engine. Fund it to defend and extend. Don't starve the cashflow source.
- 20% — Adjacent — Bets close to the core. Proven market, stretched capability, or new channel for an existing product.
- 10% — Experiments — Moonshots. Most fail. The point is optionality, not expected value.
The ratio is not universal — a startup with no core business has nothing to defend. A mature business that only funds core has no new ceiling to grow into. The split scales with the stage.
The discipline: Each bet competes against the others in its tier, not across tiers. Experiments don't cannibalize core investment — they exist in a protected budget. Without that protection, the urgent always kills the important.
Allocation in Practice
Three questions before capital moves:
- What is the current return on existing core investment?
- What adjacent market validates a 20% bet — not just a hypothesis?
- What experiment, if it worked, would create a new business?
An allocation that cannot answer all three is a budget, not a strategy.
Risk and Reward
Sizing the bet matters more than picking it. The standard discipline:
- Quantify the prediction. The CFO converts a thesis into a probability and an expected return — vague conviction is not a position. See prediction probability.
- Size the bet against the probability. A 10% experiment funded at 50% of capital is not an experiment — it is a redirected core.
- Delay gratification. Time beats timing. Compounding rewards the patient allocator.
- Avoid excessive risk. The best way to win is not to lose. Buffett's wealth model is the public reference — Berkshire's discipline is unspectacular and unbroken.
Probabilities are CFO inputs. The CFO holds the gauge that says "this experiment is worth the 10%, that one is not."
Investment Capital
When reinvestment requires external capital rather than retained earnings, the finance industry is the source. Private equity, growth funds, and strategic investors are the adjacent-and-core capital channel. Venture capital funds experiments at scale.
