See what software any business runs

Here's something most people never realize. You can tell a huge amount about a business just from its website. Which booking tool it uses. Which appointment system. Which chat widget. All of it leaves a little signature on the page, and once you can read those signatures, you can sort a thousand companies by the exact tools they pay for every month. Sales teams pay for this under the name technographic data. You can build a sharper version yourself.

There are paid services that do a rough version of this, but they miss the software a specific industry actually runs on. A careful look catches what they don't. I'll walk it on dentists, because dental software is a clean example. The same play works on law firms, gyms, restaurants, contractors, anyone.

Why this works

When a dentist's website lets you book an appointment online, the office didn't build that calendar by hand. It's using a tool from another company, and that tool quietly announces itself on the page. You don't see it as a visitor, but it's right there for anyone who looks.

Here's what the signatures look like in dentistry. These are real products, the kind you can name back to a prospect, the same way you might tell a store owner "oh, you're running Shopify."

The tell-tale signs

Two layers matter. The booking tool is the one you can spot on the page. The bigger system it plugs into (the software that runs the whole practice) you can usually figure out from which booking tool they chose.

The split worth knowing, because it changes how you'd sell to them: Dentrix and Eaglesoft are the old-guard systems that run on a computer in the back office. Open Dental is the popular budget-friendly one. Curve Dental, CareStack, and Dentrix Ascend are the modern online ones. An office on a modern online system is a very different customer than one running a dusty server in the back, and you can tell which is which without ever picking up the phone.

Then have Claude sort the practices

Knowing the software is half the picture. The other half is what kind of practice it is, and Claude gets that straight from the words on the page. A general dentist, an orthodontist, a kids' dentist, a cosmetic and veneers practice. You don't write any rules. You just show Claude the page and ask, the same way a person would glance at a homepage and instantly know.

Why this beats the old way: every dental website is built differently, so a rigid rule that works on the first ten sites falls apart on the eleventh. Claude reads the page like a human and understands what it means, no matter how it's laid out. One simple instruction, a thousand different websites.

What comes back

A slice of the finished list. The names and addresses here are made up, but the shape is exactly what you get. Most sites answer on the first, free try. The stubborn few fall through to the heavier plays.

Now you have a list nobody can buy. Every orthodontist in a city, sorted by whether they run a modern system or an old one, whether they're taking new patients, and which tools they pay for. That last part is what makes a cold email land, because you can open by naming the exact software they already use.
