Build to Continue, Not to Conclude.

In 2019, Ciaran and I, with our team at COSIMO, launched COSIMO X, a tokenized evergreen venture fund. The word in its description that mattered most to me was not “tokenized.” It was “evergreen.” I will not discuss its terms or performance here. What I want to share is what the idea taught me about building anything meant to last.

Most venture funds are built with an end date. That structure has served the industry well, and I do not dismiss it. But it has a quiet side effect. It puts a clock on every relationship. Founders feel it. Investors feel it. Decisions start to bend around the clock instead of around the company.

Some things should end. Not every project needs to last forever, and pretending otherwise is its own kind of ego. But most founders default to building for the exit without ever asking whether that is the right design. They inherit a clock and never question it.

Evergreen changes small decisions

You hire differently when you expect the person to be there in ten years. You treat customers differently when you plan to serve their children. You document your systems differently when you assume someone else will run them. You make fewer promises you cannot keep, because you will still be around when they come due.

Relationships without a clock

When a relationship has an expiration date, both sides know it, even if nobody says it. People hold something back. When it is built to continue, you can afford to be honest in a hard quarter, because you expect to work together in the good ones. The partnerships that have lasted longest in my life, with Ciaran and with colleagues across several companies, were never transactional at the core. That made trust cheaper, because we were not renegotiating it every season.

Game theory explains why. In The Evolution of Cooperation, the political scientist Robert Axelrod showed that cooperation holds when the “shadow of the future” is long: when both sides expect to meet again, honesty pays. Put an end date on a relationship and the shadow shortens. Carse’s distinction makes the same point about strategy. Play to win, and the game ends when someone wins. Play to continue, and you build differently.

Ask the evergreen question

1. Find the inherited clockList the deadlines built into your company that nobody chose on purpose: an exit date, a funding cycle, a contract term.
2. Decide which should staySome things should end. Keep the clocks you would choose again. Question the rest.
3. Hire and document for ten yearsFor your next hire and your next process, ask what you would do differently if you expected both to outlast you.
4. Make only promises you will be there to keepBefore your next commitment, ask whether you will still be accountable when it comes due.
