There’s a specific pattern that shows up in emerging markets worth paying attention to: multiple independent actors entering adjacent spaces without anyone entering the center.

The center stays empty. The edges fill up. Players arrive at the data layer, the compliance layer, the tooling layer, the distribution layer — all of them building around something rather than on it. The gap they’re implicitly pointing at is the thing nobody has built yet.

This is the adjacency signal. When it’s strong, it’s one of the better indicators that a gap is real and the timing is approaching.

Why Adjacent First

Players don’t enter the center first because the center is usually the hardest part. The adjacent spaces are easier: cleaner data, more established workflows, less domain-specific knowledge required, shorter sales cycles, clearer pricing. Adjacents are where you go when you can see the opportunity but the center isn’t ready yet — technically, economically, or in terms of customer readiness.

The center requires the adjacents. You can’t do useful synthesis without data. You can’t integrate into workflows without tooling. You can’t reach customers without distribution channels. So the adjacents come first, not because nobody sees the center, but because the center requires preconditions that haven’t been met yet.

When the adjacents start filling in, it’s evidence that the preconditions are maturing. The data layers are being built. The workflow integrations are being established. The customers are starting to understand that they have a problem that could be solved. The center is getting closer to buildable.

What the Adjacency Pattern Looks Like

The pattern has a few recognizable features.

Multiple independent actors, not coordinated ones. If multiple companies each decide independently that the adjacent space is worth entering, that’s a stronger signal than if a few players are following each other into the same position. Independent convergence on the same space suggests the signal is real rather than a trend artifact.

Complements, not substitutes. Adjacent players building things that would feed into the center, rather than things that compete with it, are a particularly strong signal. They’re implicitly assuming the center will exist and building toward it. Their products only make sense if something occupies the center eventually.

Acknowledgment of the gap. Adjacent players often describe what they’re not doing. They position carefully around the center rather than claiming to be it. This positioning is itself evidence — it means they see the gap clearly enough to deliberately avoid it, which usually means they’ve assessed it and found it too hard, too early, or outside their focus. It’s not evidence that the gap is impossible to fill; it’s evidence that it exists.

Increasing velocity. If the rate at which adjacent players are entering is accelerating, the timeline is compressing. Adjacent spaces that were empty a year ago and have three players today suggest the market is moving faster than it appears from the outside.

The Risk of Reading It Wrong

The adjacency signal can be misread in a few ways.

Adjacent players might be filling the gap indirectly. Sometimes what looks like adjacent activity is actually the gap being filled in an unexpected way. A player that starts at the edge can expand toward the center. What looks like validation of an opportunity can be validation that someone else is building toward it.

The gap might be hard for structural reasons. Some gaps stay empty not because they haven’t been discovered but because they’re genuinely hard to fill — regulatory barriers, technical limitations, customer resistance, unit economics that don’t work. Adjacent validation doesn’t rule out structural problems. It says the demand side looks real, not that the supply side is feasible.

The timing window might be narrower than it appears. Adjacent players that accumulate quickly create a compressed window. The gap may be real and the timing may be good — but good for weeks, not years. The adjacency signal says “now is becoming the right time.” It doesn’t say “the right time will last.”

Using the Signal

The adjacency signal is most useful as a calibration tool. It answers the question: is this gap real, or is it a gap because nobody wants what would fill it?

If the adjacent spaces are filling independently and the fills are complements, the answer is probably “real.” The gap exists because the center is hard or early, not because there’s no demand. That’s the kind of gap worth taking seriously.

The harder question — whether to enter the center, when, and how — the adjacency signal doesn’t answer. It just tells you the gap is there. What you do with that information is a separate problem.
