Co-Founder, TechnologyKausal Apr 2020 - PresentHelsinki, Southern Finland, FinlandFounded a startup to help cities mitigate climate change with an easy-to-use, transparent monitoring platform. It helps organisations shift from traditional, retrospective reporting to real-time monitoring so they can achieve their carbon-neutrality goals. We built Kausal on the success of Helsinki Climate Watch and refined it into an international, scalable SaaS for monitoring strategies and action plans. We also build simulation models that predict the development of a city especially from the point of view of climate mitigation.Our platform is adaptable for monitoring any other strategy that benefits from data-driven decision making. It has already taken into use in monitoring of the Helsinki Physical Activity Programme.
