OXTO Energy: Funding, Investors & Team (Sep 2026)

OXTO Energy has developed an innovative flywheel energy storage system to enable a sustainable, low-carbon future. A flywheel is considered a mechanical battery that stores kinetic energy in the form of a rotating mass. Designed to work alongside renewable technologies such as wind and solar, the flywheel allows intermittent renewable generation to continue generating, even when the energy is not necessarily required. The excess energy gets stored in OXTO’s steel flywheels and then released when demand increases. This allows for a further uptake of renewable generation and more homes to be supplied with clean, non-polluting energy.

About FundedIQ's OXTO Energy 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 OXTO Energy is left off this page rather than filled in.
