Brein helps a founder or sales team decide where to work next. It brings the work into one place:
  • what you sell and who may be a good fit;
  • published market opportunities;
  • companies and people worth reviewing;
  • contacts your team is working;
  • campaign drafts and research;
  • the context your team wants to keep.
Brein is not an autonomous salesperson. It shows what it found and why. Your team chooses what to pursue, what to reveal, and what to send.
The simplest way to think about Brein is: find it, check it, decide, and keep the result.

​
Start with one real question

Open the Brein dashboard and begin with the market or customer question your team needs to answer this week.
  1. Share your company website and, if useful, one sentence about what you sell.
  2. Review the draft profile. Correct anything that does not describe your business.
  3. Look at a short list of relevant companies and the public reasons they appeared.
  4. Open a company and review the people connected to it.
  5. Choose the people you want to know more about. Contact details stay hidden until you confirm the choice.
  6. Review the price and authorize the lookup when you are ready.
  7. Save a revealed or imported contact in Prospectos. If a verified work email is available, you can prepare a Campaña from it.
You always decide what happens next. A search, a contact reveal, and a campaign are separate actions.

What you can do in Brein

  • Empresas — search for companies that fit the market you described.
  • Personas — review masked professional profiles before spending credits.
  • Licitaciones, Proveedores, Adjudicaciones y Registros — explore published sources for opportunities, suppliers, awards, permits, and records.
  • Investigador — ask a deeper research question and return with a document you can keep and share.
  • Cerebro — keep your offer, ideal customer, exclusions, geography, messages, and team decisions in documents.
  • Prospectos — work with people your team has chosen. Companies and market observations do not become contacts automatically.
