Vainu Similar Companies: Finds Your Next Best Customers For You

We’ve been helping businesses find good-fit companies and create precise and meaningful company lists for years. Throughout the years, we’ve worked with a simple mission: Make it easy for our users to find their next best customers.

This mission has led to our continuous development of the company filter range, our expansion into the global market, the creation of proprietary data points based on AI models, and much more. 

And now we’re happy to be able to launch the next step in the evolution of our offering: Vainu Similar Companies.

What is Vainu Similar Companies?

On a technical level, Vainu Similar Companies is a brand-new dataset that uses an AI model to analyze website text embeddings to calculate the distance and difference of the domains. These distances are then converted into a similarity score, which is a decimal number between 0 and 1. The higher the score, the more similar the company.

But, on a practical level, Vainu Similar Companies is a brand-new dataset that shows, as the name suggests, similar companies to the chosen company.

Vainu Similar Companies has currently calculated this “distance score” information for over 50M domains, and we’ve stored the 100 most similar domains for each of these 50M domains in our database.

This means that all you need to do is to find one good-fit prospect among the 50M+ domains we’ve analyzed, and Vainu Similar Companies will find you the 100 most similar companies.

In this way, Vainu Similar Companies can take you from 1 good lead to 101 good leads.

The “Show existing companies” option means that companies already in your HubSpot can also appear. This is the default option.

The “Hide existing companies” option means that companies already in your HubSpot won’t appear.

The “Show from all countries” option shows results from our global database. This is the default option.

The “Show only from the same country” option limits results to companies with the same HQ country information as the company you’re looking at.
