Sean Joseph

Sean Joseph is the Co-Founder and CFO of Altilium, a deep tech company developing an innovative approach to recovering critical metals from batteries and other sources. As an asset-intensive business operating at the frontier of battery recycling and critical materials, Altilium sits at the intersection of industrial scale and climate impact, presenting a distinct set of financial challenges that few startups are equipped to solve.

On The Grove, Sean joined host for one of the podcast's first conversations with a CFO, a deliberate choice given the growing urgency around how hard tech and climate tech companies actually get funded. Sean walked through the financial vehicles available to companies like Altilium, including how founders and operators can sequence and structure capital to give a capital-heavy business enough runway to prove its technology, reach commercialization, and build toward meaningful scale. With Altilium now actively commercializing its technology, Sean brought a practical, boots-on-the-ground perspective to a conversation that is often too abstract. His appearance marks the beginning of a broader series of discussions on The Grove focused on the mechanics of funding the next generation of climate technology companies.
