GSL is the definitive customer intelligence ecosystem for residential living. We work with industry leaders, including operators, investors, developers and service providers, helping them turn insight into action.
At the heart of what we do are the voices of residents. Hundreds of thousands of them power our platforms—GSL Index®, MarketDNA®, and ResX Studio®—providing deep, comparative insight into resident decision-making, satisfaction, wellbeing, and behaviours, both within their own portfolios and across the wider sector. Our tools support measurable outcomes, from improving conversions and rebooking rates to building loyalty and delivering exceptional resident experiences.
Beyond data, we bring the sector together through thought leadership and collaboration—from initiatives like Women in PBSA and our partnership with CUBO, to flagship events such as the GSL Investor Summit and GSL Live. We champion shared learning and strategic dialogue to support continuous progress.
With AI-powered insights over 300 million distinct data points, GSL delivers transformative solutions that spark innovation and enable organisations to thrive in a dynamic environment.
