How to map a company's tech stack in under 5 minutes

Mapping a company's tech stack used to mean cobbling together Wappalyzer hits, BuiltWith exports, LinkedIn job posts, and a guess based on a press release. With anVendor, the workflow collapses to five minutes — and it's repeatable across hundreds of accounts.

Here's how to do it.

Step 1 — Start with the domain

Every research session begins at anvendor.com. Pick Search for company and drop in the prospect's domain (no https://, no path). anVendor returns a categorized list of services detected on or around that domain — analytics, marketing, sales, infrastructure, payments, security.

Step 2 — Skim by category, not by tool

The temptation is to scan the full list. Don't. The signal you need is usually in two or three categories. Selling sales enablement? Look at CRM and engagement. Selling devtools? Hit the infrastructure and developer-tools sections. Categories tell you whether you're talking to the right buyer before any tool name matters.

Step 3 — Spot the absences

The most actionable signal is often what's missing. A 200-person SaaS company with no analytics tool detected is interesting. A high-growth fintech with no fraud or compliance tooling is interesting. Absences point to a likely active vendor evaluation — or an opportunity to seed one.

Step 4 — Cross-reference adjacent tools

The tools a company has chosen tell you about budget tolerance, integration appetite, and team maturity. A Salesforce + Outreach + Snowflake stack means they buy enterprise contracts. A HubSpot + Apollo + BigQuery stack means a different conversation entirely. Read the constellation, not the individual stars.

Step 5 — Turn it into a sentence

Before you reach out, force yourself to write a one-sentence hypothesis. "They use Stripe, no fraud tool, growing 40% YoY — they're probably feeling chargeback pain." That sentence is what makes a cold outreach feel warm.

Five minutes. One sentence. Ready to talk.
