The company behind Cosa

Your own intelligence

Your Company Brain learns from every conversation and every email.

Every statement carries speaker, date and source.

Confirmed, assumed or open: you see the difference.

A new email corrects what is no longer true.

How the Company Brain works

One platform around your CRM

Your CRM and your inbox stay. Cosa builds the system around them.

One sentence from you becomes a target list, with a reason per account.

One row becomes a sequence, a draft and an email.

Only what you approve with one keystroke goes out.

How Cosa works around your CRM

Your agents, run from one place

Your Chief of Staff hands out the day’s tasks. You approve.

Chief of Staff, Sales Coach, SDR, RevOps, Sales Assistant, Content Creator and SEO/GEO Agent.

Prompted by you, run by us.

Results wait as drafts for your approval.

Questions before the first call
