hallo new opportunities

"Partnering with hallo theo has allowed me to do what truly matters: stay entrepreneurial while scaling my ambition.

By joining forces with hallo theo, we reshaped our property management business. Our processes became more professional. Our systems stronger. And our market presence far wider. What once was the management of properties in Stuttgart and its surroundings is now, as a Managing Director at hallo theo, a nationwide presence.

Together, we are building a framework that enables top-tier property management across Germany. More digital, more organized, and more aligned with the real needs of our clients. The result is a market offering that didn’t previously exist."

Founder and CEO, hallo theo GmbH

It’s time to continue your story. With hello theo.

hallo growth

As the founder and managing director of hallo theo, I know what it means to build a company. And I also know what often causes growth to fail in practice. It's not the idea, but the structures behind it.

Accounting, systems, personnel, processes: all of these things take up time and energy that should actually be spent on leadership, development and the future. This is exactly where hallo theo comes in.

We create the organisational basis so that entrepreneurship can regain its freedom. You remain active, continue to shape the business and contribute your experience. We take care of organisation, technology and scaling. Together, we create what drives us: a new generation of property management.

Frequently asked questions about selling your company


hallo clarity

1. What does “sell and stay active” actually mean? 


You sell your company to hallo theo, but remain active operationally or in a leadership role. Your entrepreneurial journey doesn’t end, it gains better conditions to grow.

This is defined individually. Many entrepreneurs continue to lead their teams or oversee their region, while hallo theo provides the structure, systems, and growth support.

Ideally, very little, except that processes become more stable, services run faster, and more resources are available. Relationships and regional proximity remain.

Your team stays. Employees are onboarded carefully and benefit from better structures, clear processes, and new development opportunities.

Because you don’t have to carry everything alone. Billing, IT, HR, processes, and scaling are handled by us, giving you more time for leadership, quality, and customers.

No. We come from property management ourselves and are building a new generation of management together with entrepreneurs. Collaborative, long-term, and deeply operational.

Yes. Beyond selling and staying in a leadership role, you can also hand over your life’s work entirely and transition into your next chapter. Here you can learn more about succession at hallo theo.
