puertafria

A spreadsheet is too little. A CRM is too much.

Six things built for cold calling, and nothing from a CRM. Import, activate, call.

Today's queue

Which company is due, oldest first. You do not choose. You call.

The research beside the call

Who they buy from, how big they are, how to get in. You read it while the phone rings.

A no is forever

You record Do not contact and the server refuses any further contact with that company. A rule, not a label.

A history that is never rewritten

Every call is appended. A correction is a new line, never a deletion.

Your CSV, in and out unchanged

Same columns. Edit it in your spreadsheet and upload it again. Stage and history are left alone.

More than one listPro

One per list or per product, each with its own tracking fields, which export with the CSV.

Compare it with a spreadsheet and a CRM

Your AI agent works the list too

puertafria has its own MCP server. MCP is the protocol an AI agent uses to talk to a tool, so the agent you already use can read the queue, open a company and record what happened.

  • Does what you do

    Checks who is due today, records a call, fills in fields, leaves a reminder, activates companies.

  • Read-only until you say otherwise

    A new key cannot write. One checkbox allows it, and you can revoke the key at any time. No key can delete.

  • The same rules

    A no is still a no, whoever is asking.
