Cocoon: Funding, Investors & Team (Aug 2026)
Cocoon is a climate technology platform that develops sustainable technology to manage industrial waste through carbon capture. It develops sustainable construction materials by transforming industrial steelmaking byproducts into low‑carbon cement substitutes used in concrete and cement production. The company’s core technology converts electric arc furnace (EAF) slag—a byproduct of modern steelmaking—into a supplementary cementitious material called LoopCem, which integrates with existing infrastructure to partially replace traditional Portland cement and reduce embodied carbon in building materials. Its process accelerates slag cooling and granulation to produce a high‑performance SCM with consistent reactivity and mechanical performance that aligns with industry standards, enabling cement and concrete producers to blend LoopCem into their formulations without major operational changes.
Cocoon has raised $15.0M across 1 funding round on record, the most recent a Series A of $15.0M announced in Mar 2026.
That round is above the $3.0M median round size for Professional Services companies tracked on FundedIQ over the last two years.

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