#19: How to Build a No Brainer Business Model: A Peek Inside a B Corp That Is Disrupting The Energy Market

You Should Do It

“The big players can't move that fast, but we have a unique edge. That differentiates us in the market." 

– Léopold Coppitiers

Sea levels are rising, more animal species are becoming extinct every day, and our cities' air is becoming unbreathable. Humanity is facing an unprecedented challenge: Global Warming. As entrepreneurs, we are confronted with the question:  How can we reduce our carbon emissions when our society and businesses are in desperate need of energy?

Skysun, a company that provides solar power solutions for small businesses, found an answer to that question and created a fantastic business out of that. Their business model is a true Win-Win. Skysun invests in the installation of a photovoltaic power plant on your property. They make the energy produced available to you for a fixed annual price. You will only pay a fraction of the public grid rates and save up to 30% of your energy bill. Isn't that amazing?

Skysun is an excellent example of developing an innovative business model and disrupting an industry. Usually, switching to solar energy seems expensive, complex, and risky. Skysun removes all of these barriers and proofs once again that it is possible to combine positive impact and profit. All these environmental problems we are facing at the moment are a massive opportunity for changemakers like us to build exceptional businesses and create an enormous change. 

Skysun is also B Corp certified, has the solar impulse label, and is committed to the SDGs #7 - Affordable and clean energy, #11 - Sustainable cities and communities, #13 Climate Action. #17 Partnerships for the goals.

Léopold Coppieters is the Co-founder of Skysun, and he is passionate about the environment and renewable energies. He started this company with the desire to make solar energy easy and accessible for everyone.

Léopold is in charge of orienting Skysun strategically. In the field, it is his job to develop long-term opportunities and growth partnerships.

In this episode, we will talk with Leopold about:

  1. Skysun story, how they got started, and the main challenges they faced along the way (and how they overcame them)
  2. Skysun innovative business model
  3. How they are financing the initial investments of solar panel installations
  4. What are they doing to expand the company outside the borders of Belgium
  5. Skysun's Impact Business Model
  6. PLUS the questions you can ask live :)

#18: How Sustainable Brands Can Sell More Online

“No one else has your DNA sequences or your life experiences. If you are able to infuse your unique traits into your brand you will differentiate yourself and stand out." 

– Amara Abara

#17: The Opportunities Businesses Have Through Carbon Offsetting And Why You Should Do It

“You have to try a lot of different things and be prepared to fail fast." 

– Dave Rouse

Every action we take and every single item we buy creates carbon emissions. And the amount of these emissions trapped in our atmosphere causes global warming and climate change.

But we not only create carbon emission through consumption in our private life - our businesses have a more significant effect. Basically, every operational step adds to our carbon footprint - yes, even a single email has a carbon cost.

Of course, it should always be your #1 priority to find solutions to minimize them. But no matter how many strategies you put in place, completely avoiding carbon emissions is practically impossible.

That is where carbon offsetting comes in. It allows companies to compensate for the emissions they produce by reducing carbon dioxide and other greenhouse gases somewhere else on the planet.

In our next episode, we will welcome Dave Rouse, the CEO of Carbon Click, a platform connecting businesses and individuals to projects that fight climate change. Companies can use Carbon Click's services to engage their customers with carbon offsets during the purchasing experience.

Dave will teach you practical steps on how to reduce your business' carbon footprint and what it means for different industries in the upcoming episode.

You will also find out how you can use carbon offsetting to build deeper connections with your target market.

And if you are thinking that you don't need all of this because you are already reducing your emissions, you should show up anyway because we will talk about why offsetting is always essential - no matter how high or low your footprint is.

#16: 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.
