There is a kind of attention that does not advertise itself. It is not the bright, fluttering attention of the conference stage or the well-edited talk. It is something quieter — a willingness to remain inside a problem long after the problem has stopped being interesting to anyone else.
We have come to believe that this is the rarest and most valuable trait in software. Markets reward founders for many things — taste, timing, charisma, narrative. But over a decade, almost all of these decay. What does not decay is the founder who has been thinking about the same compiler, the same protocol, the same molecule for seven years and still, every morning, finds a new edge of it to chew on.
An asymmetric trait
Depth of attention is not normally distributed. A small number of people can hold a single problem in their head for orders of magnitude longer than the median. They are often described, by themselves and others, as obsessive. They are often diagnosed, somewhere along the way, as autistic, ADHD, dyslexic — labels that are imprecise but that gesture at something real: a cognitive architecture that trades breadth for depth.
We do not think this is a bug to be smoothed over. We think it is the entire game. Most of the technical surfaces worth attacking — compilers, distributed systems, protein design, formal verification, mechanistic interpretability — yield only to the kind of mind that does not get bored.
What this means in practice
It means we read every cold email, but we are looking for a particular signature in them: the founder who cannot stop describing the problem, who keeps adding paragraphs, who answers a yes-or-no question with five hundred words because the truth is always more textured than the question.
It means we are slow. We meet, we read, we wait. We have passed on companies that turned out to be very good — companies whose founders happened to be excellent communicators but had not yet earned the depth that the work would eventually require. We will continue to pass on them. The price of patience is occasional regret. The price of impatience, in our experience, is much higher.
“I do not think — therefore I am, perhaps; but a tree thinks too, and so does a river that has worn a path through stone.”
We back the river.
