How to use G2 Stack internal products and services data

Use this data to see product recommendations based on what companies like yours are using or analyze the product market share of your competitors, partners, and more. You can even use this data to tailor your sales pitch before getting on a call with a potential client.

Here’s how:

Let’s say you’re about to get on a call with a representative from the Marketing team at Wag.

First, navigate to Wag’s Crunchbase profile and scroll down to the G2 Stack card.


Here we can see some of the products and services Wag is currently using. You can click the blue View All text at the bottom of the card to view a full list of active internal products. Click into these technologies to learn more about them, and become an expert on the tech/product stack of the company—before even speaking with them!


You can further your knowledge about a company’s tech stack/product history by clicking on the Products Timeline tab, which will provide you with a history of that organization’s product usage, including the start date and stop date for when they used a given technology. Here we see that Wag recently stopped using GoDaddy’s email marketing tool. This could be a great insight to bring up on your call and show your lead that you’re informed and make them feel like a priority.

 Pro Tip: To learn more about a particular technology click the blue technology name.


Clicking on a product name will provide you with more information on the Product and Product Category, as well as how many organizations in the Crunchbase dataset are currently using that product.

 Clicking either the blue text next to Category or Number of Customers will lead you to a drill-down list of all the similar products in that category or a list of the companies using that service.
