Trimde AI · The team

Marius Koller

Partner · Head of Sales and Corporate Accounts

Thirty years in sales across four countries. I started on the other side: in 1996 I ran the training centre of a software company in Munich and trained corporate clients on Microsoft products.

Back then the new technology was called Windows. Today it's called AI.

About me

Selling and teaching.

I have worked in sales for thirty years, in Germany, Austria, Switzerland and the USA. I have built and led sales organisations, from a network of more than 50 school locations to a team of ten real estate agents in Miami. I still hold first meetings myself.

I started on the other side: from 1996 to 1998 I ran the training centre of a software company in Munich and trained corporate clients on Microsoft products, mostly standing in front of the group myself. In 1998 the US company Datastream bought the business. After that I worked as a freelance IT lecturer until 2000.

I have worked with Claudia since 2013. I joined her magazine Le CITY deluxe as Vice President, and afterwards we founded House Yacht Living and Supply Disaster in Miami. We run Trimde AI as partners: Claudia builds the AI and leads most workshops; I take care of sales and corporate clients and run the AI in Sales workshop.

I know what it's like when a team has to learn a new technology while day-to-day work carries on. That's why I show AI on the tasks your team has every day anyway.

Workshop with Marius

AI in Sales

For sales teams who want to spend more time with customers and less at the desk. Half a day, in person or online, working on your team's real tasks.

  • Preparing meetings. Company, contact and occasion, gathered by AI, checked by you.
  • Offers and follow-up emails. Written faster, in your tone.
  • Practising objections. The AI plays the customer, your team practises the conversation.
  • Notes into the CRM. From the meeting into the system, without retyping.
  • What's allowed. Data protection, consent and why cold emails are off-limits in Germany.
