We build, acquire and grow companies on the journey toward
100% clean energy
100% impact hiring
100% worker ownership

Celsius advances the transition to a clean and inclusive economy by building a family of energy services companies where workers thrive and which they will ultimately own.
We are a holding company for worker-owned businesses, creating and acquiring building services companies, shifting their focus to building electrification and decarbonization, and sharing wealth with our employees through an ESOP umbrella .
What We Do
Acquire
Contractors
Celsius acquires building services firms that are in or adjacent to key industries for building decarbonization.
Shift toward
decarbonization
We shift the business models of our acquired firms to focus explicitly on decarbonization of residential and small commercial buildings.
Diversify workforce
Celsius creates new entry points to the trades for underrepresented talent through apprenticeship programs across its portfolio companies.
turn workers into owners
We make each worker at our portfolio firms an owner and decision-maker through an umbrella ESOP and open-book management practices across the Celsius family of companies.
Why We Do It
CLIMATE
Buildings are responsible for 70% of carbon emissions in cities, and 95% of all buildings in the U.S. are smaller than 50,000sf. The clean energy transition will fail unless we electrify these small buildings at scale.
​
Contractors with the expertise to educate customers and execute projects will drive the speed and scale at which decarbonization occurs.
​
​
Market
Homes and small commercial buildings are served by thousands of HVAC, electrical, and general contractors, who work transactionally to replace equipment, rather than strategically toward electrification. The mainstream market must be served by traditional-looking contractors selling comfort, quality and cost savings, which can often be best achieved while meeting electrification and energy reduction goals.
​
COMMUNITY WEALTH
Skilled labor shortages are among the largest impediment to the growth of building services firms. Yet underrepresented talent is often locked out of remunerative careers through insular hiring practices.
​
More intentional trade school and apprenticeship program partnerships can inject much needed new talent into an aging workforce.
THE OPPORTUNITY
We have the opportunity - through acquisition - to scale entirely new kinds of building contractors, focused on electrifying residential and small commercial buildings, but able to reach the mainstream consumer through existing customer relationships. And we can transform these firms to be local opportunity generators, embedding inclusive hiring practices and employee ownership, and sharing newfound clean energy wealth with workers on the frontlines of the energy transition.
Imagine a world where tradespeople on the frontlines of decarbonization own the companies for which they work, and share in the largest wealth-building opportunity of the next half-century, all while accelerating the energy transition by virtue of their expertise and excellence.

We're Scouting for Acquisitions
We're seeking contractors in industries including solar installation, HVAC, insulation and weatherization, commercial and electrical services.
​
We target firms within a 60-mile radius of Philadelphia that have revenues of $5M to $10M, $750k+ in EBITDA, 10+ years in business, and at least one experienced manager in place. We seek situations in which owners wish to retire, but we welcome owners who are open to remaining involved as General Managers in their businesses for up to two years post-sale.
​
Most importantly, we seek owners who love their employees, and wish to see them benefit from a company acquisition and continue to propel the company toward enduring prosperity and impact.

Here's How We Help Companies and Workers Thrive
Post-acquisition, we build on the solid foundation of each portfolio company by:
​
Investing in growth, with a focus on systematizing marketing tactics, upgrading customer acquisition partnerships and cross-selling energy solutions across Celsius companies.
​
Investing in technology, with a focus on upgrading field technician software, payment systems, search engine optimization and CRM databases.
​
Investing in people by:
-
transforming employee benefits and wealth-building tools
- diversifying talent recruitment
- investing in professional development and career pathways
- engaging frontline employees in company decision-making
