De Regenboog Groep: conversation skills for Onder de Pannen

De Regenboog Groep in Amsterdam runs a service called Onder de Pannen: legal subletting, also known as lodger renting. The coordinators talk with landlords and tenants. This is not about selling in the classic sense, but about persuading, trust and the right questions.

In 2025, I delivered a training in conversation and questioning techniques for this team, fully tailored to their conversations.

Many salespeople think selling is mainly broadcasting: telling a lot and showing a lot of product knowledge. In this training, participants learned the opposite. Whoever asks the right questions keeps control. Every answer determines the next question, until the customer takes the step to a decision. The 11 scientific topics show why that works.

Asking questions does not just work better, it also makes you come across as friendlier. You give the customer attention, and with the right choice of words you make every question stronger. What customers say themselves, they remember best, and they connect it to you. Together, these techniques make selling much easier.

What this delivers

• For De Regenboog Groep: more landlords taking part in Onder de Pannen.
• For landlords and tenants: a conversation in which concerns are taken seriously and trust is built.
• For social organisations: whoever wants to persuade people needs the same skills as a good salesperson.

"Hele interactieve training met veel concrete tips and tricks. Heel leuk om met deze nieuwe kennis en inzichten aan de slag te gaan en dit eigen te maken." (Dutch review)

Do you want this for your team too?

Does your team also need to persuade people, without it feeling like selling? Then questioning techniques are the key. Who would not want every customer conversation to run deliberately and by system?

The approach at De Regenboog Groep fits the in-company sales training or Consultative Selling training. I tailor every training to your market, your product and your customer.
