Lewi was founded by Vishnu Avudainayagam and Geraldine Terada-Bellis. While working as process engineers at a water utility, we found that the software available to use was outdated and inefficient and our day-to-day tasks in modelling and analysis took longer than they should. We believed that there must be a better way – so we founded Lewi, with the aim to simplify decision making, streamline feasibility assessments and de-risk sustainable technology investments.
