Kelvin: Funding, Investors & Team (Aug 2026)
Kelvin is a platform that manages energy and electrification specifically designed for buildings with radiator heating systems. The Radiator Labs system incorporates intelligent thermostatic radiator enclosures (known as Cozys) connected to central heating controls, resulting in reduced fuel wastage, lower building emissions, and enhanced comfort for occupants. Through its hybrid electrification platform, Kelvin allows buildings to electrify a significant portion (60-80%) of their heating needs at only a fraction of the cost compared to other electrification options. With the Radiator Labs Hybrid Electrification technology, buildings can be programmed to optimize heating fuel sources based on factors such as energy pricing, building energy efficiency ratings, and carbon penalties. This technology enables radiator-heated buildings to meet the emission limits set for NYC in 2030 while offering substantial cost savings. The efficacy of Radiator Labs' technology has been confirmed by NYSERDA, which found an average savings of 25.5% in heating costs. Moreover, this technology has been recognized and awarded by various organizations, including the MIT Clean Energy Prize, Popular Science Innovation Award, Verizon Powerful Answers Award, Architizer A+ Award, The 1776 Challenge Cup, and the New York City Department of Buildings Carbon Neutrality Innovation Challenge. Radiator Labs is also part of the inaugural cohort of The Clean Fight, a program supported by NYSERDA and the New Energy Nexus.
Kelvin has raised $30.0M across 2 funding rounds on record, the most recent an undisclosed round announced in Oct 2023.

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