Advancing the Hospitality Industry with a Smart Technology Solution

Join us on our journey towards smarter buildings and a greener tomorrow.



SensorFlow is a Singapore-based, full-stack company that combines the use of wireless IoT solutions and AI-driven automation to make smart buildings a reality. Starting with hotels, our solution enables smart building management through maximised energy efficiency, optimised operational productivity, and enhanced sustainability. 

Founded by Saikrishnan Ranganathan (CEO) and Max Pagel (CTO) in 2016, SensorFlow evolved from the pressing need for energy optimisation worldwide.


“We aim to combat climate change on a global scale
with IOT and AI technology.”

Where it all started

Sai and Max recognised that hotels are one of the biggest victims of poor energy efficiency. However, like most buildings and properties, they face large barriers to adopting existing solutions as many properties are limited to small Operations Expenditure budgets and available solutions are not only costly but also massively disruptive to install. With that, SensorFlow developed a retrofit IoT solution that enables any building/property on any budget to optimise their energy consumption with no operational disruptions and at no upfront cost. We also help improve a building's overall productivity and efficiency by providing actionable insights from big data collected via our large network of advanced IoT devices.
