ClearSky significantly influences the startup ecosystem by partnering with industry veterans, such as through Clarum Advisors for energy transition consulting, and maintaining a track record across multiple closed funds since 2014.[2][4] Key sectors include cybersecurity (safeguarding digital landscapes) and sustainable energy (accelerating the global energy shift), with a network of experts providing strategic support to portfolio companies.[2][3]

(Note: Search results also reference a separate entity, Clear Sky/Clear Sky Capital, a real estate investment manager focused on multifamily, self-storage, and manufactured housing with $1.6B AUM, but the query's "ClearSky" aligns with the VC firm based on branding and sector prominence.)[1][5]

Origin Story

ClearSky was founded in 2012 by Alex Weiss (CEO, Co-Founder, and Managing Partner) and partners including Erik Straser, establishing it as a specialized VC and growth equity manager.[3][4] Emerging from a recognition of converging needs in cybersecurity threats and the global push for sustainable energy, the firm quickly built expertise as industry insiders, managing its first funds by 2014 and closing others in 2019 and 2020.[2][4] Key evolution includes over a decade of refining focus on transformative tech, culminating in partnerships like Clarum Advisors with veterans Jan Vrins, David Port, and David Allen to bolster energy transition thesis development and portfolio support.[2]

Early traction stemmed from a proven track record of returns and impact, raising approximately $1B in commitments while navigating tech and energy markets.[2] This insider perspective on trends and opportunities solidified its position, with offices in West Palm Beach anchoring operations.[4]
