Persium was born from a shared conviction: that you cannot manage what you cannot measure. Combining expertise in environmental science and advanced IoT engineering, Ali, Alex and Cameron founded Persium to bridge the gap between high-cost monitoring and the need for hyperlocal, actionable intelligence.
Together, they have led Persium from a London-based startup to a global leader in environmental sensors, data and solutions. Their vision remains unchanged: to provide the transparency and high-resolution tools required to build a more breathable future for cities worldwide.
