London-based Tewke, a company working in energy optimisation and home automation, has raised £1.5 million in its second funding round. The round saw participation from <span class="hover:entity-accent entity-underline inline cursor-pointer align-baseline"><span class="whitespace-normal">JamJar Investments</span></span>, <span class="hover:entity-accent entity-underline inline cursor-pointer align-baseline"><span class="whitespace-normal">Cur8 Capital</span></span>, <span class="hover:entity-accent entity-underline inline cursor-pointer align-baseline"><span class="whitespace-normal">Energy Mix Ventures</span></span>, and <span class="hover:entity-accent entity-underline inline cursor-pointer align-baseline"><span class="whitespace-normal">Project Ventures</span></span>. Angel investor <span class="hover:entity-accent entity-underline inline cursor-pointer align-baseline"><span class="whitespace-normal">Vlad Yatsenko</span></span>, co-founder and CTO of <span class="hover:entity-accent entity-underline inline cursor-pointer align-baseline"><span class="whitespace-normal">Revolut</span></span>, also participated. Founded in 2020 by Piers Daniell and Rowan Dixon, Tewke develops smart home technology aimed at simplifying how households manage energy. Its flagship product, Tap, is designed and engineered in the UK and does not require rewiring. Importantly, Tap works in homes without a neutral wire. As a result, it is compatible with more than 90% of UK housing stock. The company positions the product as an alternative to installer-led smart home systems that often require complex setup. Beyond basic lighting functions, Tap supports household energy optimisation. It helps users shift electricity consumption based on time-of-day tariffs, which can lower energy costs and reduce emissions. This approach aligns with Tewke’s broader focus on improving residential energy efficiency using contextual, AI-driven intelligence. The company builds its core technology in-house, including patented hardware, firmware, and its proprietary operating system, Tewke OS. In 2025, Tewke introduced TewkeAI in collaboration with <span class="hover:entity-accent entity-underline inline cursor-pointer align-baseline"><span class="whitespace-normal">Google</span></span>. The contextual AI framework uses data from Tap’s nine onboard sensors to analyse behaviour, movement, air quality, and temperature patterns inside the home. According to the company, this data-driven approach enables more responsive energy management while maintaining ease of use for households. The newly raised capital will be used to support go-to-market execution and expand Tewke’s engineering team. This includes work on neuro-symbolic AI systems designed to improve residential energy performance. In addition to equity funding, the company also receives non-dilutive support from <span class="hover:entity-accent entity-underline inline cursor-pointer align-baseline"><span class="whitespace-normal">Innovate UK</span></span>, which continues to back its technology development efforts. —---------------------- Raising capital?

Global asset manager Galvanize has closed its Real Estate Fund I with $370 million in commitments. The capital comes from institutional investors, including pension funds, foundations, banks, registered investment advisers (RIAs), and family offices.
The fund focuses on commercial buildings across fast-growing markets in the United States. Its strategy places decarbonisation at the centre of value creation.
Energy prices have risen steadily in recent years. At the same time, electricity demand continues to increase. As a result, property owners and tenants face growing operational costs. Galvanize aims to address this issue by investing in energy upgrades that reduce both emissions and long-term expenses.
These upgrades include on-site renewable energy systems, electrification projects, and energy-efficiency improvements. According to the firm, these measures can lower emissions while protecting properties from rising energy costs.
Katie Hall, Co-Chair and CEO of Galvanize, explained the firm’s approach. “We’re showing that sustainability isn’t just a side note. It’s right at the heart of making money and standing out”. Energy volatility creates ongoing opportunities to leverage decarbonisation for value creation.”
Galvanize Real Estate (GRE), the firm’s real estate investment arm, combines traditional investment expertise with scientific and technical knowledge. Its team includes climate scientists, technologists, and policy specialists.
Before making investments, the group evaluates each building’s potential for decarbonisation and resilience upgrades. In addition, a portion of the fund’s long-term incentives depends on achieving operational net-zero emissions within three years.
So far, GRE has invested in five projects across 15 buildings in 11 U.S. cities. These properties cover approximately 2.4 million square feet of space.
Through solar deployment, electrification, and energy-efficiency measures, the firm expects to reduce emissions by 153% across the portfolio. These changes could prevent an estimated 8,224 metric tons of emissions annually.
Joseph Sumberg, head of Galvanize Real Estate, said rising energy costs and power reliability concerns are shaping investment decisions. “Our strategy is designed to generate long-term value across our growing portfolio,” he said.
The broader commercial real estate market presents several challenges. For instance, data centres currently attract a large share of investor capital. This trend has reduced liquidity for other property types.
At the same time, many owners of energy-inefficient buildings hesitate to sell. They often worry that current market conditions could lead to lower valuations. According to Sumberg, about 60% of bids do not result in completed sales.
However, limited liquidity can also create opportunities. Investors with available capital may find favourable deals in markets with fewer buyers.
Sumberg explained this dynamic: “The lack of transparency in pricing leaves opportunities for experienced investors with capital. We are lucky enough to be one of those.”
Meanwhile, global energy uncertainty continues to influence operating costs. On average, energy expenses have risen between 15% and 20%. As a result, energy-efficiency upgrades can act as a cost hedge for both investors and tenants.
The GRE team works with a network of specialists to implement decarbonisation projects across its properties. The strategy combines capital investment, on-site energy technologies, and policy insights.
This approach allows the firm to upgrade existing properties while acquiring buildings that align with its decarbonisation thesis.
Galvanize was co-founded by billionaire investor Tom Steyer and Katie Hall. Former U.S. Secretary of State John Kerry joined the firm in 2024. The company invests across several asset classes, including seed, venture, growth, public equities, credit, and real estate.
The firm’s commercial real estate strategy plans to deploy up to $1 billion, although less than half has been invested so far. Galvanize itself committed $15 million to the current fund.
Sumberg noted that energy resilience is becoming an important factor in property valuation. “Rising energy prices and market volatility make decarbonisation a strong lever for NOI growth,” he said.
The firm reports that its first portfolio has already produced measurable results. Solar installations and electrification projects have reduced emissions while lowering energy costs. These changes also contribute to higher net operating income (NOI).
In addition, energy-efficient buildings are becoming more attractive to tenants. As companies focus on sustainability and cost control, demand for resilient properties continues to increase.
Galvanize believes this shift could strengthen the role of decarbonisation in commercial real estate investing. The firm continues to monitor global energy trends, particularly those influenced by geopolitical developments and supply constraints.
According to the company, integrating profitable decarbonisation into property upgrades may help create resilient assets and stable long-term returns.
