Climate Tech Investment Trends 2024: Bigger Rounds & Later Stages

Climate Tech Investment Trends in 2024

Despite a slight downturn in overall funding, the climate tech sector demonstrated signs of maturation in 2024, evidenced by increased deal sizes.

Venture Capital Investment Overview

Venture investment within the climate tech landscape experienced a 7% decrease, totaling $12.9 billion. This figure represents a $1 billion reduction compared to the investment volume observed in 2023, as detailed in a recent PitchBook report.

The report highlights a notable trend: an increase in average round size and a growing investor preference for companies beyond their initial seed funding stage.

Shift in Investor Focus

For several years, investment strategies prioritized early-stage ventures, with substantial capital allocated to pre-seed and seed-stage startups. This emphasis stemmed from the relatively nascent nature of the climate tech industry.

Following a period of stagnation after the clean tech bubble burst during the Great Recession of December 2007, both founders and investors refined their strategies. This involved exploring new markets and adopting innovative technologies.

Maturation of Climate Tech Startups

This strategic shift initially fostered opportunities within the early stages of company development. However, as these startups have progressed, they have begun to secure larger, later-stage funding rounds accompanied by higher valuations, according to PitchBook’s analysis.

Key Metrics from 2024

In 2024, the median deal size reached $7 million, a $1 million increase from the previous year. Simultaneously, median pre-money valuations rose significantly to $44.5 million, up from $31.5 million in 2023.

The total number of deals decreased by 27%, totaling 568. For comparison, in 2023, climate tech startups secured $13.9 billion across 782 deals.

Broader Market Influences

The performance of climate tech in the past year mirrors wider trends observed across all investment sectors. While the overall deal count declined, the total deal value approached levels seen in 2022.

This increase in deal value was largely driven by substantial investments in artificial intelligence-focused companies, including Anthropic, Databricks, OpenAI, xAI, and Waymo. These companies collectively accounted for 43.2% of all deal value in the fourth quarter.

Post-Pandemic Investment Correction

The recent slowdown in climate tech investment follows a period of heightened activity during the pandemic. Increased venture capital inflows into climate tech, alongside other sectors, led to growth in deal sizes, counts, and valuations.

Currently, early-stage companies seeking follow-on funding are encountering a more rigorous investment climate. Investors are now scrutinizing unit economics more closely.

Startups demonstrating strong financial performance are attracting larger deals, while those facing challenges are finding fundraising more difficult, as reported by investors.
