Collective Retreats is an experiential travel company redefining the accommodations experience for travelers through a collection of unique luxury retreats in unexpected places. Collective Retreats was built with an asset-light business model, meaning that each destination was created with minimal materials, removing the permanence of brick and mortar. A veteran of the hotel industry, CEO Peter Mack correctly identified that the majority of hotel revenue is spent on property expenses and upkeep, and not toward furthering the guest experience. Many of these costs were tied to the physical hotel building and in order to reallocate these funds for unique guest experiences and hospitality, Peter decided to turn the hotel business model upside down. Whereas many hotels and resorts pride themselves on the grandeur and stateliness of their buildings, Collective Retreats aims to create as little barrier as possible between one’s surroundings and one’s accommodation. Without sacrificing luxury hospitality, the destination retreat manages to refresh its image every year while providing the comfort of a five-star hotel to its guests.

impak’s mission is to help investors and lenders make more sustainable decisions by providing them with assessments that go beyond ESG and include both the negative and positive impacts of their assets, whether listed or private. A leading investor-based impact rating agency – impak offers human augmented transparent, comparable, measurable, and rigorous environmental and social data (impact data). The goal is for money managers to integrate reliable impact data into their decision-making processes in order to enable capital to finance a positive impact economy - one up for the social and environmental challenges we’re currently facing. Our offer is suited for institutional investors, bank CIBs, asset managers, wealth and private equity managers, ETF managers and creators, and sustainable investment services. The impak ScoreTM and the impact statement - both developed by impak, and the result of our IMP and SDG based methodology, are at the base of our offer and allow for data contextualization, double-materiality analysis, and alignment with new regulations thanks to our customizable modules such as European Union Taxonomy, SFDR, Climate Strategy, etc.). For example, impact statements allow our clients and partners in the financial sector to better manage their internal and external risks, and to identify opportunities having a positive impact, essential to a long-term perspective of climate change and impact alpha. We represent the second generation of extra-financial rating agencies, avoiding the pitfalls of first generation ESG ratings and ensuring a real change of economic paradigm.
