In 1847, Hungarian obstetrician Ignaz Semmelweis faced a deadly puzzle: why were new mothers in his doctors' ward dying of puerperal fever at drastically greater rates than those in the midwives' ward? He cycled through theories such as bad air, overcrowding, and even the route a priest took past the beds. Then he landed on something strikingly simple. Doctors were moving straight from autopsies to deliveries without cleaning their hands.

Semmelweis ordered everyone to wash their hands with a chlorinated lime solution. Mortality plunged from 18.27% to 1.27% almost overnight. One minute of scrubbing proved more powerful than every elaborate theory on the table. Semmelweis discovered an arbitrage opportunity.

Arbitrage

Arbitrage is a familiar word in finance. It usually means a price gap. The same asset trades cheaper in one place than another, and a profit sits in the difference.

Underneath that definition is a simpler idea. Arbitrage is an asymmetry between input and output. A small, cheap action on one side. A large payoff on the other. Semmelweis spent a minute at the washbasin and saved a ward. The input was trivial. The output was enormous. That gap was the opportunity.

The Opportunity in Plain Sight

Financial professionals tend to hunt for financial arbitrage. Consultants tend to hunt for a different kind: time arbitrage.

A quick audit of an ordinary week, hour by hour, surfaces it fast. Two hours spent formatting a slide deck. Half an hour copy/pasting each time a certain process is run. 10 minutes trying to track down that one email and make sure it is the latest one in the chain.

None of it feels wasteful in the moment. Each task looks small. Added up across a week, a quarter, a year, the total is hard to stomach. There is often a misperception, though, about how to solve it.

Going Big Is Not the Only Way

Much of the media in 2026 has pitched one version of AI: go big. The company-wide transformation. The platform overhaul. The multi-quarter program with a steering committee.

That path works for some firms. Is it the only way to achieve great results with AI? No.

With only a couple thousand dollars, small and mid-sized firms have been posting spectacular results with AI. They focus on one problem. They find a simple solution. They reflect on the learnings. Then they move on to the next problem to solve. They are not undertaking a massive transformation. But they are transforming their business.

Small Wins Compound

It also highlights an important point: small wins tend to become something bigger.

Imagine a firm got just 1% better every week for all 52 weeks in a year. How much better would it be by the end? Not 52%. Closer to 68%, because the gains compound. Each small win has direct benefits. But it also generates excitement. It builds confidence. It expands the imagination. It perpetuates bottom-up innovation.

And it ultimately creates a whole that is larger than the sum of its parts.

History Repeats Itself

In 1847, Semmelweis found a simple fix that cut deaths in his ward from 18.27% to 1.27%. Today, small and mid-sized firms are finding that same kind of leverage in AI: small, cheap actions that return far more than they cost. The tools are finally within reach of everyone. The key is how they are applied.
