Circu Li-ion: Funding, Investors & Team (Oct 2026)

Circu Li-ion is a battery upcycling company headquartered in Luxembourg. It’s our ambition to accelerate the green revolution by maximising the value of each battery to enable a truly sustainable economic electrification. Battery demand is growing—and so is the need for sustainable solutions along the value chain. In 2021, we have embarked on our journey to enable a circular lifecycle for batteries in three steps: the dismantling of batteries into material pure subcomponents, individual cell diagnostic and reassembly into useful 2nd life applications - automated and at scale. We provide our technology to leading players in the space of micromobility, q-commerce & delivery, hardware manufacturing and recycling. Our Machine-as-a-Service solution offers the possibility to capture the true value of still functioning resources through upcycling instead of recycling, which currently destroys 100% of the batter pack - saving money and the planet (- 48% battery CO2 emissions compared to a traditional battery life cycle).

About FundedIQ's Circu Li-ion Funding Data

FundedIQ tracks announced funding rounds and refreshes this profile every week. Round dates, stages and amounts are normalised to a single format, converted to US dollars, and de-duplicated: two records of the same round announced days apart are merged, and two genuinely different rounds are kept apart on the amounts they disclose. Amounts shown are the disclosed figures only — a round announced without a number is listed and excluded from the total rather than estimated.

Employee counts are reported bands, not exact headcounts. Founder and executive names carry the job title on record. Anything we do not hold for Circu Li-ion is left off this page rather than filled in.
