Growth equity, also referred to as late-stage private equity or expansion capital, involves the provision of capital to mature companies that have already established proven traction, demonstrated scalable business models, consistent revenue growth, and often positive or near-positive unit economics.
These investments are designed to fuel rapid scaling, geographic expansion, product diversification, market leadership consolidation, or preparation for liquidity events such as initial public offerings (IPOs) or strategic acquisitions.
Unlike early-stage venture capital, which accepts high uncertainty in exchange for potential outsized returns, growth equity targets lower-risk opportunities with more predictable financial performance.
Unlike leveraged buyouts in traditional private equity, growth equity typically involves minority stakes and minimal or no debt financing.
Key Characteristics of Growth Equity Investments
Growth equity investments share several consistent features:
- Stage focus: Series C, Series D, pre-IPO, or post-IPO follow-on rounds.
- Company profile: Revenues typically in the range of US$10–150 million annually (often higher in mature markets), with strong gross margins, repeatable unit economics, and clear paths to profitability.
- Ticket sizes commonly range from US$20 million to US$200 million+ per transaction.
- Ownership structure: Usually minority positions (20–49%), though some funds take majority stakes in select opportunities.
- Holding period: Generally 3–7 years, with exits pursued via IPO, trade sale, secondary purchase, or recapitalisation.
- Return profile: Seeks lower multiples than early-stage venture but higher certainty through de-risked business models and operational maturity.
- Value-add: Emphasises execution support, including professionalisation of management, governance enhancements, international expansion, mergers and acquisitions, and operational scaling.
Relevance to Climate Tech / Cleantech
Growth equity participation in climate tech and cleantech has increased significantly in recent years and is now a critical financing channel for the sector. The relevance arises from the capital-intensive nature of commercialising proven technologies and the need to bridge the “missing middle” between early venture funding and large-scale infrastructure or debt financing.

Key drivers include:
Commercialisation and scale-up
Growth equity supports companies that have validated technologies (e.g., advanced energy storage, solar-plus-storage systems, green hydrogen production, sustainable fuels, carbon capture solutions, and circular economy processes) and require substantial capital to achieve commercial deployment, manufacturing ramp-up, or market penetration.
High capital requirements
Cleantech projects often involve significant upfront expenditure on equipment, facilities, pilots, and supply-chain development. Growth equity provides the patient capital needed to reach operational scale and positive cash flow.
De-risking for larger investors
Late-stage funding reduces technical and market risk, making projects more attractive to infrastructure funds, development finance institutions, and debt providers.
Path to infrastructure-scale impact
Many cleantech solutions transition from pilot to utility-scale or industrial application at the growth stage, requiring capital to secure offtake agreements, regulatory approvals, and manufacturing capacity.
Alignment with global transition goals
Investors target companies that contribute directly to decarbonisation, energy access, resilience, and adaptation, often in high-growth emerging markets.
Prominent global growth equity investors active in climate tech include:
- Breakthrough Energy Ventures (late-stage climate focus)
- Energy Impact Partners
- Fifth Wall
- Generate Capital
- TPG Rise Climate
- Temasek (climate-focused growth mandates)
African Examples
In Africa, growth equity in cleantech has gained momentum, particularly for companies that have achieved commercial traction and are scaling proven solutions in energy access, renewables, and climate resilience. Notable recent examples include:
- M-KOPA: Secured US$160 million in growth funding in 2025 to expand its pay-as-you-go solar and appliance financing platform across East Africa, building on its established user base and revenue model.
- Sun King: Raised US$196 million in late-stage capital in 2025 to scale off-grid solar products, manufacturing, and distribution, leveraging its proven pay-as-you-go traction.
- Spiro: Attracted US$100 million in growth equity in 2025 to expand its electric motorcycle and battery-swapping infrastructure across West and East Africa.
- d.light: Received substantial growth financing (including debt and equity components) in 2025 to scale solar home systems and clean cooking solutions, supported by development finance institutions and private investors.
- Bboxx: Tapped a US$300 million World Bank-backed facility in 2025 to accelerate solar access and energy-as-a-service models in Nigeria and other markets.
These transactions highlight that growth equity in African cleantech targets companies with demonstrated revenue, customer adoption, and repeatable models, enabling them to scale infrastructure, expand regionally, and deepen impact in underserved energy markets.
Looking Ahead
Growth equity/late-stage investors represent a vital category for climate tech and cleantech, providing the substantial capital and operational support required to commercialise proven technologies and achieve large-scale deployment.
In Africa, where energy access and climate resilience remain pressing priorities, growth equity is increasingly financing companies that have moved beyond pilot stages and are ready to scale impactful solutions.
The combination of de-risked models, clear revenue paths, and alignment with global sustainability goals makes this investor class highly relevant to the sector’s next phase of growth.
