Company Overview

Lowercarbon Capital is a venture capital firm that invests in companies developing technologies to reduce and remove carbon emissions from the atmosphere. The firm was founded in 2018 by Chris and Crystal Sacca, who previously oversaw early-stage investments into Instagram, Slack, Twitter, and Uber at their earlier firm, Lowercase Capital.

The firm organizes its investment activity around three areas: funding technologies that cut new greenhouse gas emissions across energy, industrial materials, and transportation, backing carbon removal approaches designed to draw down atmospheric CO2, and supporting technologies aimed at mitigating near-term climate impacts.

Lowercarbon Capital operates as an early-stage and growth-stage investor, deploying capital through multiple funds rather than manufacturing products or delivering direct services. It has over $2 billion in assets under management and invests across sectors including clean energy, carbon removal, sustainable materials, food and agriculture, transportation, and advanced manufacturing. The firm has also raised dedicated vehicles for specific themes, including an $800 million climate fund and a separate $350 million fund focused specifically on carbon removal startups.

Headquartered in San Francisco, California, the firm has backed a portfolio that spans hard-technology ventures such as fusion energy and industrial decarbonization alongside software platforms supporting the clean energy transition. Portfolio companies include ventures operating in India, Europe, and other international markets in addition to its primary US focus.

Why These SDGs Matter

Lowercarbon Capital’s investment thesis centers on funding technologies that reduce, remove, or mitigate carbon emissions, directly supporting SDG 13’s call for urgent action to combat climate change and its impacts. The firm’s backing of clean energy ventures, including thermal energy storage and fusion power companies, contributes to SDG 7’s goal of ensuring access to affordable, reliable, and modern energy. Its support for hard-technology innovation across industrial materials, manufacturing, and infrastructure, including companies developing lower-carbon chemical production and industrial processes, aligns with SDG 9’s emphasis on building resilient infrastructure and fostering innovation.

Approach & Methodology

Lowercarbon Capital operates as a specialized venture capital investor rather than a technology developer, deploying capital and operational support across a portfolio of climate technology companies. The firm structures its investment activity around distinct funds, including a general climate fund and a dedicated carbon removal vehicle, allowing it to allocate capital to companies at different stages, from seed to growth.

The firm has developed in-house scientific expertise to evaluate deep-tech and hardware-heavy climate solutions that require technical underwriting many generalist venture firms are not equipped to assess, such as fusion energy, direct air capture, and industrial electrochemistry. This technical evaluation capacity supports its stated focus on hard-technology ventures.
Startup Intros

Beyond capital, the firm’s involvement with portfolio companies includes business development advice, market strategy input, and operational guidance, along with introductions to potential customers, co-investors, and technical hires. Its investment selection reportedly avoids ventures without a clear path to scale or a credible technical team, indicating a due diligence process weighted toward technical and commercial viability rather than early-stage narrative alone. The firm’s portfolio construction spans multiple sectors, including energy, transportation, industrial materials, and agriculture, rather than concentrating on a single technology vertical.

Market Position

Lowercarbon Capital operates in the climate technology venture capital segment, positioned toward early-stage and growth-stage hard-technology companies rather than generalist startups. Its primary customers are climate technology founders seeking capital and technical validation for ventures in energy, industrial materials, carbon removal, and transportation. The firm is among the most active and ambitious climate-focused investors globally, alongside firms such as Breakthrough Energy Ventures, together managing several billion dollars in committed capital. Its differentiation stems from a stated willingness to back capital-intensive, scientifically complex ventures that many traditional venture firms avoid due to long development timelines and technical risk.

Procurement Considerations
  • Fund thesis alignment with hard-technology and carbon-focused ventures
  • Stage fit, as the firm invests from seed through growth rounds
  • Expectations around board involvement and portfolio support
  • Co-investment and syndicate structure on larger rounds
  • Technical due diligence process and evaluation timeline
  • Fit with the firm’s stated preference for ventures with a credible path to profitability
Funding, Recognition & Ecosystem
  • $800 million climate fund closed in 2021
  • $350 million dedicated carbon removal fund announced in 2022
  • Investment from BBVA into Lowercarbon’s carbon capture-focused fund
  • Portfolio includes companies that have reached unicorn valuation status, including Commonwealth Fusion Systems and Solugen
  • Co-founder Chris Sacca previously ranked on the Forbes Midas List for venture investing performance
Natnavi Analysis

Lowercarbon Capital occupies a distinctive position within climate finance as one of the more prominent venture firms willing to underwrite capital-intensive, scientifically complex technologies, including fusion energy, direct air capture, and industrial electrochemistry, that many generalist investors consider too risky or too slow to return capital. Its scale, with billions of dollars under management across multiple funds, gives it meaningful influence over which hard-technology climate startups receive early risk capital.

The firm’s significance lies less in direct emissions reductions, since it does not operate technology itself, and more in its role as a capital allocator that has helped several climate technology companies reach commercial scale and unicorn valuations. Its dedicated carbon removal fund reflects an early and specific bet on a subsector that has since attracted broader institutional interest.

Limitations include the inherent difficulty of independently verifying a venture firm’s portfolio-level impact claims, since outcomes depend on the eventual commercial success of individual portfolio companies rather than the firm’s own operations. As with most venture investors, detailed financial performance and fund-level returns are not publicly disclosed, which constrains external assessment of the firm’s track record beyond notable individual company outcomes.
