Thank you for sharing your feedback with us. We’re pleased that you find the work interesting and as you noted, if you are curious about the drinks industry, then it’s super interesting work! When people are working on data-crunching or have their headphones/airpods in, it can feel like there isn’t much room for chatting. We hope that you’ve been able to join our many social events that we have organised in the London office, and we hope to keep organising more in 2026. Being a data company, the office culture is more on the professional side of things, but when the office is busy, and people are grabbing breakfast or coffee/tea, there’s always lots of chatter and catching up on what’s going on for each other. Please let the People Team or our Office Manager know if there’s anything else that might make the office environment more sociable. We appreciate hearing feedback from our people and work hard to create a professional and engaging culture for everyone.

Thank you for sharing your feedback with us. We’re pleased that you think our Company is "Brilliant" ! We really appreciate your unsolicited feedback to help us learn and keep building a great company culture for all our people. We recognise that at certain times of the year, especially during the Research cycle and major product releases, the workload increases and it can feel quite heavy during these periods. We appreciate the passion and dedication our people demonstrate and we reward this dedication by having a more flexible holiday schedule in the second half of the year. It is helpful to know that the workload feels heavy and we have taken many steps to automate certain processes and data upload processes through better systems and enhanced processes. We will keep working on this.

Thank you for sharing your feedback with us. We’re pleased that you find our company culture and atmosphere inspiring. We put a lot of thought and effort into ensuring that we create an inclusive and welcoming environment and that we hire great people for you to work with. With the doubling in size of our People team since October, we are working with our Leadership Team to create templates to support them in building out clearer Career pathways and frameworks to help our people understand the skills required in their current roles and how to develop skills ready for the next role, whether they’re looking to move sideways, upwards or elsewhere, so we are keen that you will feel the benefits of that as it rolls out. We encourage everyone to discuss their skills development needs with their Manager and the People team will guide and support these discussions by identifying appropriate learning solutions to meet those needs. It’s early days in building these robust Talent Management frameworks at IWSR, but we will be starting to build clearer growth paths to support your career this year.
