Who we are
We're a team of interdisciplinary experts, researchers and builders in sustainability, data science, political science and software engineering.
Our founding story
What do a Sustainability Expert, a Political Scientist and a Software Engineer have in common?
A passion for empowering investors to drive real change through collaborative data-sharing, and a deeply-held conviction that stewardship can be measured.
Eleanor, Siyana and Dan leveraged their diverse academic backgrounds and private sector experience to build rezonanz's dynamic insight and collaboration engine. Their shared vision for amplifying investors' voices has guided them each step of the way.

“There is still too often a significant difference between the aspirations of asset owners and the way asset managers vote at general meetings, particularly when it comes to sustainability issues. A ranking of this kind is therefore all the more important because it enables asset owners to form an idea of how asset managers vote on their behalf.”
Vincent Kaufmann
“rezonanz provides comPlan with valuable insights into our voting track record, enabling us to benchmark this critical aspect of stewardship against other investors. With rezonanz's advanced analytics, we can identify gaps and strengthen our commitment to long-term sustainability alignment.”
Roman Denkinger

"More and more asset managers disclose all their votes online, providing more opportunity for sweeping analysis of their voting behaviour. New players have emerged in the sustainable finance ecosystem, such as the Swiss start-up rezonanz, to mine this information. The company has developed a tool for benchmarking voting behaviour and continued commitment to sustainability priorities, aggregating and analysing large volumes of data. In time, we could have more nuanced and data-driven insights that run deeper than simply analysing the rate of support for shareholder proposals, which are still far from the norm in all markets."
