The Sacca Vision: Beyond Traditional Climate-Tech

Chris and Crystal Sacca have fundamentally redefined venture capital’s approach to climate technology through Lowercarbon Capital’s unconventional investment thesis. Their vision extends far beyond traditional cleantech, particularly in the water sector where they’ve championed solutions that others might consider too ambitious or risky.
At the heart of their philosophy lies a profound understanding that water challenges require more than incremental improvements. The Saccas actively seek entrepreneurs developing breakthrough technologies that could transform entire industries. They specifically look for solutions that can scale exponentially while delivering outsized environmental impact.
Lowercarbon’s water technology portfolio reflects this bold approach. Rather than focusing solely on efficiency improvements or minor technological tweaks, they back ventures tackling fundamental challenges in water access, treatment, and conservation. This includes supporting technologies that radically reimagine desalination processes, wastewater treatment methods, and water quality monitoring systems.
What sets their investment philosophy apart is the emphasis on convergence – supporting teams that combine multiple cutting-edge technologies to create novel solutions. The firm particularly values innovations that synergize artificial intelligence, advanced materials science, and biotechnology to address water challenges.
This ambitious vision is grounded in pragmatism. The Saccas understand that for climate solutions to achieve meaningful scale, they must be economically viable without relying on subsidies or regulatory mandates. They seek water technologies that can compete on cost and performance while delivering environmental benefits.
Their approach to water technology investment parallels their broader thesis on climate investing. They believe that transformative solutions often emerge from unexpected places and that conventional wisdom can be a barrier to breakthrough innovation. This openness to unconventional ideas has positioned Lowercarbon to identify and support some of the most promising advances in water technology.
The firm’s commitment extends beyond mere capital provision. They actively leverage their network and expertise to help portfolio companies navigate regulatory challenges, establish strategic partnerships, and accelerate market adoption. This hands-on approach has proven particularly valuable in the water sector, where commercialization paths can be complex and time-consuming.
Portfolio Deep Dive: Water Solutions That Make Waves

Lowercarbon Capital’s water technology portfolio reflects an astute understanding of the sector’s most pressing challenges, focusing on breakthrough innovations that can scale rapidly. Their investments target three critical areas: water access, quality enhancement, and resource recovery.
In the water access domain, the firm backs technologies that radically improve desalination efficiency while slashing energy consumption. These solutions employ novel membrane materials and processes that operate at a fraction of conventional energy requirements, making clean water production economically viable in water-stressed regions.
For water quality enhancement, Lowercarbon champions advanced treatment technologies that address emerging contaminants like PFAS and microplastics. The portfolio includes cutting-edge solutions that destroy these forever chemicals rather than merely concentrating them, representing a paradigm shift in treatment approaches.
Resource recovery investments demonstrate particular promise in the circular economy. Portfolio companies are developing processes to extract valuable materials from wastewater streams, transforming treatment facilities from cost centers into profit generators. These technologies can recover critical minerals, nutrients, and energy while simultaneously treating water – a dual-benefit approach that dramatically improves the economics of water treatment.
What sets these investments apart is their potential for exponential impact. Rather than incremental improvements, Lowercarbon seeks solutions that can deliver order-of-magnitude advances in performance or cost-effectiveness. This approach has attracted co-investment from major industrial partners, accelerating the path to commercialization.
The firm’s portfolio companies share common characteristics: highly scalable business models, protected intellectual property, and the ability to generate rapid customer adoption through compelling economic advantages. This focus on commercial viability alongside environmental impact has resulted in several portfolio companies achieving significant market traction within months of deployment.
Investment Strategy: The Science of Scaling Water Innovation

Lowercarbon Capital’s approach to water technology investments follows a rigorous methodology that blends scientific validation with market-driven scalability. The firm’s investment thesis centers on technologies that can deliver exponential impact while maintaining capital efficiency.
