London, United Kingdom, November 30, 2014- After extensive discussions, we've decided to re-brand Serene Enterprise Alliance CIC as ExigoSolar Ltd effective from next year. The re-branding was driven by two circumstances. First, as a limited company, ExigoSolar will have greater operational and business flexibility than its original structure as a social enterprise (CIC), allowing us to better serve our partners and clients. Second, ExigoSolar as a brand resonated more with our shareholders and will enable us to become more effective in our marketing campaigns in the coming year ahead.

London, United Kingdom, March 15, 2014- We’ve been very busy over the last two weeks attending Eco-build 2014 and World Water Tech Investment Summit in our native London. Also prior to the conferences we flew out to Germany to visit with one of our key partners: SolarSpring to learn more about their technology, needs and strengthen our ties. Serene Enterprise Alliance focuses on being pro-active and these past two weeks is just an example. 

Eco-build 2014 and World Water Tech Investment Summit were fantastic opportunities for Serene Enterprise Alliance to meet with thought leaders, prospective clients and business partners. During both conferences we were able to engage leading businesses and governments on how our 100% solar powered desalination and recycled water solutions can meet their water needs. We felt after both conferences we were able to cultivate a number of opportunities but also learn more which will only help improve our young company. 

Our management team prior to both conferences visited Freiburg, Germany to meet with SolarSpring to enhance our working relationship. Over the two day visit, Serene Enterprise Alliance was able to get a better understanding of SolarSpring, their work and how we could assist them in becoming a market leader. This coming summer we are looking forward to heading back out on the road to continue to generate awareness of our work and more importantly help communities and businesses at the frontlines of climate change combat water shortages.
