Gyaros is a bare spine of rock in the Aegean, waterless, fit for goats and the men Rome wanted to forget. Nero sent Musonius Rufus there in the year 65, after the plot against the emperor collapsed and he went hunting for Stoics to make examples of. Exile to Gyaros was a threat Romans used on each other; now it was his address, with no return date.

He did not sit on the shore waiting to be recalled. He walked the island until he found a spring, which, the story goes, drew a few settlers who had heard there was water. Students crossed the sea to study under him. He kept the hours he had kept in Rome, the same reading, the same teaching, on an island that offered no reason to keep any hours at all.

The Stoics had a word for what he was doing, and it is the most misread word they left behind. Apatheia. It looks like apathy and means close to its opposite: freedom from being ruled by the destructive passions, the panic and the craving and the false high and the despair. A man of apatheia still acts, still decides, still cares what becomes of things. The swing simply stops driving him.

Apatheia is equanimity in action. It is the discipline a founder needs to survive a correction that refuses to end on schedule.

Venture funding to Southeast Asian tech firms fell by almost eighty percent between 2022 and 2024, from roughly ten billion dollars to a little over two. Fortune called it a protracted slump this month, with founders decamping to California to escape it. The fourth quarter of 2024 closed at just over a billion dollars across 116 rounds, the fewest in more than six years, and the full year came in near half of what the region raised at the pandemic peak. This is what a winter looks like once it has run long enough to stop being weather and become climate.

Eighteen months in, the founder is fighting his own nervous system more than the market.

The passions arrive on the calendar. In a red month, when the pipeline is dry and payroll is close, fear says cut, and he cuts the wrong things: the slow bet, the good engineer, the part of the roadmap that only pays in year three. In a green week, when a single up-round clears at a flattering number, elation says the winter has broken, and he hires against a spring that has not come. Both readings are wrong for the same reason. Both let the day set the decision.

Apatheia is running the business the same on the green days and the red ones, deciding from the plan rather than the adrenaline while still feeling every degree of the weather. Musonius did not pretend the island had water. He went and dug until it did, and taught while he dug. He had no term sheet and no board. He had the same problem you do.

Men are disturbed not by things, but by the views they take of things.

Epictetus, who studied under men like Musonius, put the mechanism in a line: men are disturbed not by things, but by the views they take of things. The funding number is a thing. The despair is a view, and so is the euphoria, and the views are the only part of the winter that was ever up to you.

Here the discipline turns dangerous, and honesty demands saying so. Apatheia curdles into numbness the moment it becomes a reason not to feel the stakes. A founder no longer moved by a bad quarter has often stopped being moved by the people inside it: the team going unpaid, the customer let down, the number that should frighten him because it is real. Equanimity that stops registering cost has quietly become dissociation wearing composure’s clothes. The test is plain. The calm founder still moves the moment the spring can be dug; the numb one has stopped digging and called it peace.

Apatheia is running the business the same on the green days and the red ones.

The winter will end when it ends, on its own schedule and not on yours. The only thing you hold between now and then is whether you keep the same hours.
