  Led · Series B · Nov 2022

  Dandelion Energy is an Arlington, VA–based home geothermal company led by CEO Dan Yates. The company recently launched the Dandelion Geo heat pump, which delivers high heating performance. Dandelion positions itself to empower modern homeowners and home builders to adopt premium, emissions-free heating without a premium price tag. It plans a two-pronged nationwide expansion: distributing its heat pump technology to installers and homeowners, and implementing large projects for production home builders and multifamily developers. Financially, the company completed a $40M Series C and previously raised $70M in a Series B1 in 2022. Founder Kathy Hannun was included on CNBC’s inaugural Changemakers List and the company added Lauren Howard as Chief Revenue Officer in 2024. Dandelion Energy builds and installs residential geothermal heat pump systems that include wifi-enabled monitoring to help homeowners replace fossil-fuel heating and cooling. The company focuses on making geothermal accessible and affordable for modern homeowners. Led by CEO Michael Sachse, Dandelion targets both retrofit and new-construction markets. It plans to use recent funding to expand those markets and to develop a broader range of products to serve more customers and geographies. The company has completed its 1,000th geothermal installation, an operating milestone cited in the article. Dandelion Energy develops and installs geothermal heating and cooling systems for homes, aiming to reduce carbon emissions and remove reliance on purchased heating fuel. The company aligns federal, state, and utility incentives so homeowners can upgrade to geothermal for less than their current heating and cooling costs. Led by CEO Michael Sachse and based in Peekskill, N.Y., Dandelion has built a virtual sales and design process and expanded operations into Connecticut. In 2020 the company surpassed 100,000 tons of carbon emissions avoided. Dandelion intends to use the new funds to expand operations further while continuing to invest in research and development. Its total funding after the raise stands at $65M. Dandelion Energy sells affordable residential geothermal heating and cooling systems intended to replace gas, oil, propane, and electric heat. The company began at Alphabet’s X lab and launched as an independent business in New York City in May 2017; it now operates out of New York City and Upstate New York. Over the past year Dandelion tripled its customer base and employee headcount, and it cites product‑market fit as it scales operations. The company plans to expand operations and further invest in research and development to support continued growth and innovation. Dandelion’s mission is to enable widespread adoption of geothermal by delivering a cost‑effective, fossil‑free home heating and cooling product. Leadership changes include Michael Sachse being named CEO while co‑founder Kathy Hannun transitions to President to focus on product innovation. Dandelion Energy develops smaller-scale geothermal heating and cooling systems for residential homes, using a compact drilling approach that enables one-day installations. Its heat pump is a connected device with about 60 sensors to monitor performance and enable proactive alerts. Installations cost roughly $20,000–$25,000, with the company claiming homeowners can save about $35,000 over 20 years; roughly 50% of customers finance installations. Dandelion has accrued a waitlist of “thousands” of homeowners and currently offers services only in New York. The company plans to use new funding for R&D, hiring, opening warehouses for equipment and supplies, and business development to expand beyond its current market. Kathy Hannun is the CEO and the company spun out from Alphabet X in May 2017.
