Not every gap in the market is equal. The research process surfaces opportunities at different confidence levels, and collapsing them all into “yes” or “no” loses useful information.

A useful distinction: Tier-1 vs. Tier-2.

Tier-1 is a finding where the signals converge cleanly. There’s a clear workflow gap, a single weak incumbent or no incumbent at all, a defined buyer persona with budget, a transaction-triggered demand driver (meaning the work gets done whether anyone feels like doing it or not), and multiple independent signals pointing to the same gap. This is an entry point.

Tier-2 is a finding where most of those conditions are present, but one or two are weaker or missing. The gap exists. There’s documented manual workflow. But maybe the buyer persona is less defined, or the market size is harder to confirm, or the distribution path is different enough to require separate effort. Not no. Not yet.

What Makes a Finding Tier-1 vs. Tier-2

The difference usually comes down to three factors: signal count, buyer clarity, and distribution overlap.

Signal count: A Tier-1 finding hits four to five signals clearly. A Tier-2 finding hits three to four, with some ambiguity. More signals means more independent confirmation that the gap is real and that people care about it.

Buyer clarity: Tier-1 findings have a buyer you can describe specifically. You know what industry they work in, what firm size they’re at, how they find new tools, what conferences they attend. Tier-2 findings often have a real buyer, but one that’s harder to reach or less clustered. The distribution path is more diffuse.

Distribution overlap: Tier-1 findings become more compelling when they share a distribution channel with another product you’re already building. If you’ve already paid the cost of becoming trusted in a particular professional community, additional products that serve that same community get cheaper to sell. Tier-2 findings often require building a new distribution relationship — possible, but it resets the go-to-market effort.

The Research Implication

When a research arc surfaces a Tier-1 finding alongside several Tier-2 adjacents, the right response isn’t to build for all of them at once. The Tier-1 finding is the entry point. The Tier-2 findings are a map of what’s adjacent.

The map has value. If you start building for the Tier-1 buyer and your first customers are happy, the Tier-2 findings tell you what to ask them about next. “Do you also produce [document type]?” If the answer is yes and often, you’ve validated the expansion path without additional research.

The Tier-2 findings also tell you what to watch for. If a competitor enters a Tier-2 space and builds traction, that’s signal that the entry conditions were stronger than your research suggested. It doesn’t mean you missed an opportunity — it means the market is real and you now have a competitor to learn from.

What Tier-Two Isn’t

Tier-2 isn’t “not worth pursuing.” It’s “not worth pursuing first.”

The distinction matters because Tier-2 findings often decay differently than Tier-1 findings. A Tier-1 gap in a high-vocabulary-barrier niche can stay open for years because the people who could spot it are also the people too deep in the work to zoom out. A Tier-2 gap that’s slightly more visible may have a shorter window.

Keeping a list of Tier-2 findings and periodically checking whether new tools have entered is a cheap way to stay oriented. If you do an annual pass and find that a Tier-2 gap has remained open for two or three years with no entrants, that’s worth reassessing. The conditions that kept it Tier-2 may have changed.

The goal isn’t to find the one perfect market and ignore everything else. It’s to know which door to open first — and have a clear sense of what’s waiting behind the others.
