Air Pollution Has A Profound Impact On Our Health

Did you know that air pollution directly causes between 28,000 and 36,000 deaths in the UK every year, with those living in cities affected the most? This is particularly noticeable in communities that are clinically vulnerable, from minority backgrounds or have lower socio-economic status. We are committed to addressing this issue and improving the health of all people impacted by air pollution.

"We've been on previous accelerators, but Growth Studio's programme was on another level. It helped us articulate the business, created a strategy for communicating our message, and got us pitch-ready.

Paul and Rayan's knowledge and enthusiasm came through from the first call and throughout the programme, and you genuinely felt like they cared about your business. Our business is a much better place since going on the accelerator, and we're closer to funding than ever before."
