Bridging data,
strategy and social impact.
Leith Symes is a strategic advisor and data specialist with experience spanning not-for-profit services, public health, and research. He has built a career at the intersection of evidence and action — helping organisations not just collect data, but understand it, communicate it, and use it to drive meaningful change.
What sets Leith apart is a rare combination: the technical fluency to build data infrastructure from the ground up, and the sector knowledge to understand what community organisations actually need — and what they don't. He has designed impact measurement systems, developed theories of change, built business intelligence dashboards, written successful funding submissions, and shaped policy advocacy for organisations working at the frontline of some of Australia's most pressing social challenges.
He is a trusted voice in Victoria's community services sector — contributing to housing and homelessness policy through regional advocacy networks, and engaging with peak bodies across community services, anti-poverty, and social inclusion. He brings that external perspective — of where the sector is heading, what funders are looking for, and what arguments are landing — directly into his consulting work.
Sympact CI was founded on a belief that purpose-driven organisations deserve the same quality of strategic and analytical support as any corporate — designed for the real constraints of the sector, and built to last beyond the engagement.
