Levi ist einer jener Geschäftspartner, die mit viel Geduld und Sachwissen uns als Kunde neue Möglichkeiten im Vertrieb, aber auch die eigenen Grenzen aufgezeigt hat.
Alexander Szlezak

Sein Talent, Kundenbedürfnisse schnell zu verstehen, und seine Begeisterung für Problemlösungen sind seine größten Stärken.
Deniz Dallar

Ich fand es immer sehr inspirierend zu sehen, wie er es schaffte sein großes Kundenportfolio zu managen und dabei jeden Kunden zufrieden zu stellen.
Diana Erler

Ich habe ein Jahr lang mit Levi an unserem Sales Prozess gearbeitet. Vom Message Market Fit über die Definition der Buyers Journey bis hin zum detaillierten Feedback zu Sales Gesprächen und KPIs war Levi stets ein sehr zuverlässiger Ansprechpartner und hat maßgeblich zum Wachstum in 2022 beigetragen.

Neben seinem Support bei der Formulierung unseres Message-Market Fits hat er uns auch dabei geholfen, die vielen Terminbuchungen von potentiellen Neukunden richtig zu qualifizieren, sodass diese zu wertigen Kunden unserer SaaS Flixcheck geworden sind. Ich schätze seine strukturierte Arbeitsweise und seine Expertise im Sales sehr und kann ihn wärmstens empfehlen.

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.
How the Chief of Staff leads the agents

Questions before the first call
