Built by someone who had to close the deals himself.

Before Cosa, Levi spent years inside B2B sales processes — over 170 client engagements, helping companies build and run commercial motions that generated more than EUR 30M in revenue. The pattern repeated everywhere: deals did not die because sellers lacked effort. They died because nobody could say, with evidence, where a deal actually stood and what had to happen next.

CRMs logged activity. Call recorders transcribed conversations. None of them could answer the only questions that matter: which commitments has this buyer actually made, what is blocking the next one, and what do we send to unblock it. Every answer lived in a rep’s head — or nowhere.

So he built the system he needed: deal intelligence with provenance. Every claim traced to the line in the conversation where the buyer said it. Every assumption visibly flagged until validated. Every next step executed as deal-ready collateral, not left as a CRM task. The methodology came first — the 7 Decision Gates, distilled from those 170+ processes — and the software was built around it.

Cosa is developed and operated by LC0 Builder in Germany. It runs on its own medicine: every Cosa deal is worked through Cosa, and the cases on this site come from those live deals.
