About us

eWEning star is an impact-driven startup, with a vision of healthy planet, which can sustain also the generations to come. Yes, we are for-profit organisation, but for us sustainable business, means economically and environmentally sustainable business. Therefore, one of our goals is to become a profitable business, but also commit to invest a significant part of our profit to new initiatives which further aim to accelerate Energy Transition and make a positive impact. This way our users don’t only get directly to improve their own workflow, but also contribute even further to new impact-driven initiatives!

We are also committed to user empowerment and decline any proposals related to targeted marketing or selling of the individual user-data. We are driven by high ethical standards.

As we are impact-driven and recognise the urgency of acceleration of Energy Transition in all societal levels and by a variety of stakeholders, we also commit to affordability of our discovery tools. Contrary to many other businesses, we are not targeting a limited number of high-paying customers, but we are aiming for a large number of users with lower pricing model. This way we aim to support as many people as possible who aim to accelerate the Energy Transition as fast as possible.
