Rimm Sustainability is proud to announce a strategic partnership with The Social Investment Consultancy (TSIC), a global leader in social impact advisory, inclusive evaluation, and systems change.
This partnership marks a significant milestone in Rimm’s mission to scale sustainability and impact infrastructure globally—combining advanced technology, data intelligence, and deep domain expertise to accelerate measurable outcomes across markets.
Rimm has acquired a stake in TSIC. TSIC will retain its established brand, operational leadership, and intellectual autonomy, with Bonnie Chiu continuing to lead the organisation while joining Rimm’s senior leadership team to help shape global social impact strategy.
A step-change for global impact
As the impact landscape evolves, organisations are moving beyond fragmented reporting and advisory toward integrated systems that enable real, scalable impact.
This partnership reflects a shared belief: the future of the impact sector lies not only in insight, but in infrastructure.
By combining TSIC’s deep knowledge infrastructure with Rimm’s AI-powered technology and data platforms, the partnership will accelerate the transition from impact reporting to institutionalised, scalable impact—enabling organisations to embed, measure, and scale impact across their operations and investments.
Scaling impact across global markets
With a combined footprint spanning the UK, Asia, and emerging markets, Rimm and TSIC are uniquely positioned to support organisations, governments, and financial institutions in operationalising ESG and impact at scale.
This partnership also represents one of the few global impact platforms led entirely by Global Majority leadership—bringing diverse perspectives to the forefront of how sustainability is defined, delivered, and scaled globally.
“Through this strategic partnership we are redefining how impact is delivered globally. Together with TSIC, we are bridging the gap between intention and implementation; combining world-class expertise with technology that enables impact to be embedded, measured, and scaled across markets.”
— Vivek Aswani, Chief Commercial Officer, Rimm Sustainability
“For close to two decades, TSIC has been working deeply in the impact sector to prove that equity and excellence go hand-in-hand. Today, as impact finally moves to the fore of global policy and capital, we are seeing a historic convergence of sustainability and technology.
For us, this partnership with Rimm is about meeting that moment. It gives us the engine to reach a truly global scale without ever diluting the mission and values that have defined us. Too often, organisations have to choose between breadth and depth. This partnership breaks that trade-off, creating a unique opportunity to link grassroots communities all the way to large-scale capital, building the infrastructure required to truly change systems. By bridging this gap, we are ensuring that the future of global sustainability remains grounded in the deep, lived expertise that TSIC has always championed.”
– Bonnie Chiu, Managing Director, TSIC
Continuity for clients, acceleration for impact
There will be no disruption to ongoing projects. Instead, clients and partners will benefit from enhanced technological capabilities, deeper data insights, and more scalable solutions as a result of this partnership.
Rimm and TSIC look forward to working together to build the next generation of impact infrastructure.
