Thin SaaS is dying. Vertical SaaS isn't.

The shakeout isn't random — it has a shape. Depth, data, and distribution survive; surface doesn't.

The shakeout has a shape

Watch which products are actually dying and a pattern appears. It's not 'SaaS' that's dying — it's a specific genus: the thin, horizontal, one-feature-deep tool that could have been built by anyone. Meanwhile vertical products — software built deep into one industry's actual workflow — keep compounding retention and pricing power.

The difference isn't the market size or the team's talent. It's what's underneath the UI. A thin product is a feature set. A vertical product is an understanding of a workflow so specific that the software is almost incidental.

Why depth is the defense

A vertical product embeds domain knowledge that can't be extracted from a landing page: the weird edge cases of dental billing, the actual approval flow in freight brokerage, the taxonomy real adjusters use. A clone can copy what your product does — it can't copy what you know. Every support ticket and onboarding call from the last two years is load-bearing.

That knowledge converts to data, and the data converts to retention. When your product holds two years of a customer's operational history in your domain model, switching isn't a software decision — it's a data-loss decision. That's why vertical SaaS churns less and survives clone attacks better.

Key takeaway: The question 'is SaaS dead' has a boring answer: the products that were always just features are dying; the products that are actually expertise-as-software aren't.

The vertical playbook, condensed

If you're deciding what to build — or what your current product could become — the surviving pattern looks like this.

Pick a workflow, not a market

'Tools for contractors' is a market. 'How contractors handle change orders' is a workflow — and the thing you can own.

Go deep before going wide

One workflow solved completely beats five solved adequately. Depth is where the data and the loyalty live.

Let usage produce the moat

Benchmarks, templates, industry data — the product should get smarter about the domain every day it's used.

Stay where the niche congregates

Vertical buyers cluster — trade communities, industry newsletters, niche directories. Distribution is cheap when the audience is concentrated.

For indie founders, vertical is the cheat code

Big companies chase horizontal markets because they need huge outcomes. Small teams can own a workflow the giants consider too small — and 'too small' is exactly where the moats are defensible. A $30K/month vertical tool in a niche nobody's heard of is a better business than a generic tool fighting forty clones.

The distribution math is kinder too: in a niche, the communities are findable, the keywords are winnable, and 'where do people in this industry look for tools' has a short answer. Thin SaaS has to shout at everyone. Vertical SaaS whispers to the right room.

Key takeaway: The most durable indie software business is boring-looking software for a specific kind of customer — distributed through the few places that customer actually gathers.

Get in front of your niche

List free — buyers browse by category, and in a niche the right listing reaches the exact room you need.
