The fastest way to understand Brein is to complete one small task: go from a public website to a person your team explicitly chooses.
1

Open Brein

Go to app.trybrein.com, sign in, and choose your workspace.
2

Tell Brein what you sell

Add your public company website. If the site is unclear, add one sentence in your own words.
3

Check the profile

Review the offer, likely buyers, geography, exclusions, and the kinds of public events you want to explore. Edit anything that is wrong, then save it.
4

Review the first list

Brein shows a focused list of companies and why each one appeared. Open a result to see the public event, the supporting sources, and what is still unknown.The list is a starting point, not a complete map of the market. An empty result does not prove that a company or opportunity does not exist.
5

Choose the people

Inside a company, review masked professional profiles. Searching for people does not spend contact credits. Choose the people you want to know more about.
6

Confirm the contact lookup

Brein shows the selected group, the price, and the available balance. Confirm only after you have reviewed those details.
7

Save the contact

A revealed or imported person can be saved in Prospectos. A verified work email can become the starting point for a Campaña, but creating a draft never sends it.

What you should have at the end

You should be able to answer four questions in the workspace:
  • Why did Brein show this company?
  • Which people did we choose?
  • What contact information is available?
  • What should the team do next?
Read the workspace guide to see what each part of Brein is for.
