Technographic targeting lets you filter companies by the software they actually use — so every account on your list is already a fit before you write the first email. Here are three strategies to do it.

## 1\. Must-have technologies

Find accounts using a technology your product requires or complements. These prospects already have the infrastructure your product plugs into, which shortens the sales cycle and increases conversion.

**Examples:**

-   A company using **Prometheus** is a natural fit for **Grafana**
-   A company using **ClickHouse** is a candidate for **ClickHouse Cloud**
-   A company using **Kubernetes** likely needs observability, security, or cost-optimization tooling

**How to do it:** Search for companies with active job postings mentioning the target technology. Job postings reveal backend and internal tools that website crawlers miss — if a company is hiring someone with Prometheus experience, they're actively investing in it.

## 2\. Competitor customers

Identify companies using a competitor's product to build displacement lists. These accounts are already paying for a similar solution, which means:

-   They have **allocated budget** for this category
-   They understand **the problem** your product solves
-   You can tailor positioning around **specific switching benefits** (cost, features, migration ease)

**How to do it:** Filter by the competitor's technology name. Combine with company size and geography to focus on segments where you win most often. Prioritize companies with multiple job postings mentioning the competitor — that signals deep adoption and a bigger contract opportunity.

## 3\. Partners or integrations

Target accounts using tools your product integrates with. A clear "works with your stack" message removes friction and increases conversion because the prospect can see immediate value.

**Examples:**

-   If your product integrates with **QuickBooks**, target companies using QuickBooks
-   If you offer a **Slack integration**, find companies standardized on Slack
-   If you connect to **Stripe**, target e-commerce companies using Stripe for payments

**How to do it:** Build a list of partner or integration technologies your product supports. Search for companies using any of those tools, then segment by industry or company size to match your ICP.

## Getting started

All three strategies follow the same workflow:

1.  **Define your target technologies** — list the must-have tools, competitor products, or integration partners relevant to your product.
    
2.  **Search for companies using those technologies** — use [TheirStack's technology filter](https://theirstack.com) to find companies with active job postings mentioning your target technologies. Filter by company size, location, and industry to match your ICP.
    
3.  **Export and prioritize** — export the list and prioritize by signal strength: companies with multiple recent job postings mentioning the technology are more likely to be actively investing.
