#15: Building A Thriving Community & Integrating Connection As A Business Success Factor

“Money is just a tool to reach your goals. But the more money you create and the more profit you have the more impact you can make on the community you serve." 

– Hidde Van Gelder

In our fast-moving and digitalized society, we face a lack of deep and fulfilling human connections.

Zoku is a new kind of hotel that aims to disrupt the hotel industry and solve this problem.

They not just sell rooms and coffee to their guests like most other hotels but combine the element of home-office with the services of a hotel and the social factor of a thriving neighborhood. 

Hidde is the Community Manager at Zoku and also an inhouse B Leader. His everyday work is to engage the community and uphold Zoku’s values of 'Better Together.’

Hidde believes that when more people have this mindset, the world would be driven by passion, which results in making meaningful business instead of just making money. 

In the upcoming episode, we will talk about how Zoku managed to build a business that solves a core problem of their target market (the internationally mobile professional): the loneliness while being on business trips and the lack of connection.

You will learn how Zoku created a thriving community and what principles and strategies they put into action to keep it engaged - even during the current global pandemic.

#15: Sustainable Copywriting That Drives Cultural Change

“If Never jump from 'Never Heard About You' straight to the sell. You have to offer people the opportunity to change their minds with your support and by helping them." 

– Sabine Harnau

People say they want to live more sustainably. But they don't. As you probably know, driving behavioral change is way more challenging than most people think.

Great copy inspires people to take action. Period. It is a super powerful skill to have.

Copywriting can be used for good and drive people to take positive action or can be used for your benefits, driving people to buy shit they don't need to impress people they don't even like... 

In this episode, we talked to Sabine Harnau, founder of From Scratch, a copywriting agency on the mission of building a fairer, greener future.

She started the agency to stop climate change, save species from dying, and make society more humane.

In this episode, she will share practical tips to help you better communicate your story, optimize your website conversions, and inspire your clients and community to take action, helping you be the driver of change.

#14: Brand Activism & Greenwashing - How to Differentiate True Purpose from Superficial Intentions

Brand Activism is on the rise. Following a new generation of "woke“ consumers buying according to their belief, brands increasingly are changing their communication as well.

Brands become more upfront, challenging, and demanding. However, we can find profit-driven companies and brands deceptively communicating "sustainable" values in products and services in order to appeal and make them look better to socially and environmentally aware consumers. 

In this session, we talked about the underlying dynamics of this trend and find clarity on this topic by asking the right questions. Karry is a research & purpose consultant, helping companies implement the triple bottom line and re-imagine business as a force for good. As a B Corp Ambassador, she had been involved in various environmental campaigns and movements, working together with impact-driven brands and helping them to translate their purpose into action, through community building, launching activistic initiatives, and campaigning.

– Frank Bömers

Today’s Episode it’s an interesting one. Sina had a good talk with Frank Bömers on the topic of PURPOSE.
