Lead Customer Success Manager

What is Sylvera anyway?Sylvera provides trusted ratings, tools and data for carbon credits and CDR. Our mission is to incentivize investment in real climate action.

Purchasing carbon credits and CDR through the carbon markets is one of the most established and scalable ways to channel finance to effective climate solutions and work toward societal net zero. Unfortunately, the carbon markets were plagued with mistrust and a lack of effectiveness since they\’ve emerged – until Sylvera.

To help organizations ensure they\’re making the most effective investments, Sylvera provides trusted ratings, tools and data for carbon credits and CDR. Our data and software independently and accurately validates the impact of carbon projects that capture, remove, or avoid emission whether they are up and running, or in development. Our data and tools allow users to optimise both the climate and economic performance of projects as well as understand the past and future of the market. With Sylvera, businesses, governments and developers can confidently invest in, benchmark, deliver, and report real climate impact.

Our team is made up of leading minds in climate change from science to policy, finance, and carbon markets. We work in partnership with scientific organizations, universities, governments, and think tanks to develop and implement rigorous and holistic project assessment methodologies, leveraging the latest technology. We also partner with actors and institutions across the whole market to make data higher quality, more standard and more accessible. Founded in 2020, Sylvera has 130+ employees globally with offices in London, New York, and Singapore. We\’ve raised over $96 million from leading investors like Fidelity, Balderton Capital, Index Ventures, and Insight Partners to date.
