SunDensity: Funding, Investors & Team (Aug 2026)

SunDensity has developed a groundbreaking Photonic Smart Coating (PSC™) technology that enables the up and down conversion of the wavelengths in white light (UV to IR) to match the desired band which can solve several in-efficiencies in photonics. By conversion of spectrum, they have developed, and field tested a patent-pending PSC™ that significantly reduces the cost of electricity generated by solar photovoltaics (PV) applications, customizes thermal and optical behavior of architectural glass, and increases the quantum efficiency of optoelectronic instruments.

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