Investing in a Sustainable Future
Sustainability is integrated into how we invest, operate and grow. We back founders who are building solutions that make a lasting difference.
We bring experience, energy and partnership to help these visionary companies scale responsibly and go further, because our mission is simple: to make more possible for the people shaping the future.

Our Approach to Sustainability
Making more possible through responsible growth
At Molten, sustainability is not an add-on. It is embedded in our investment process and our culture. We consider environmental and social impact from the moment a company enters our pipeline to how we help it scale responsibly. Our goal is to generate lasting value, commercial, social and environmental.
Partnerships and Reporting Bodies
We remain confident that sustainability will be a driver of long-term value creation.
We partner and report to global organisations that set the benchmark in responsible investment, from the UN-supported Principles for Responsible Investment to Diversity VC and the Investing in Women Code. Each partnership strengthens our accountability and transparency.



Portfolio engagement
Where sustainable decisions drive lasting value.
Our role does not end when we invest. Each year, we work closely with founders to track progress against measurable goals on climate, inclusion and governance. In FY26, every new investment considered positive environmental or social impact as part of its assessment. Through active engagement, we help portfolio companies embed sustainability principles and deliver measurable performance.
Sustainablity Across the Portfolio
Our portfolio companies are on the front line of change, from AI-powered healthcare to data tools for the energy transition. Together, they show how innovation and sustainability go hand in hand. Explore examples from across the portfolio to see impact in action.

UK's most ethical online florist, delivering fresh, responsibly sourced flowers nationwide and supporting sustainable practices, fair trade, and charitable initiatives.

Arena Flowers
Location: London, UK
Sector: Ai, Deeptech & Hardware
Arena Flowers have developed one of the first closed-loop flower waste and soil feed systems, which takes flower waste such as trimmings and converts it to either biofertiliser or recyclable and compostable paper to wrap Arena Flowers. This has led to reductions in waste generated from operations, as well as to the cost of raw materials to grow and deliver flowers, representing a significant step in making the business’ operations more circular
In addition to circularity, Arena Flowers is reducing its consumption of water and energy by replacing traditional soil planting with hydroponic systems and choosing to grow seasonal flowers which reduces the demand for heat and light to create favourable growth conditions.
Not only is Arena Flowers reducing their impact on the earth’s resources by working towards becoming more circular and reducing resource consumption, they are also actively supporting biodiversity by developing bee colonies around their headquarters in Droitwich. This endeavour recognises and highlights the interconnectedness of multiple systems in the final product of a business highlighting that the effects of and on a business are not isolated only to its operations. Arena Flowers has been recognised for its strong commitment to sustainability across its business by the Butterfly Mark certification, a recognition awarded to luxury brands that are committed to and furthering sustainability across their operations.
Arena Flowers demonstrates how flowers are not always representative of environmental exploitation through extractive practices but can be a means to combat climate change and waste if businesses become more conscious of their supply chain and consumers become more conscious of their buying habits.

FintechOS
Location: London, UK
Sector: Enterpise technology
FintechOS is a global leader in high productivity fintech infrastructure, striving to simplify and accelerate the launch and service of innovative financial products, with a focus on personalized customer experiences and digital transformation.

As part of the portfolio engagement target set out in our Climate Strategy in our novel climate engagement with FintechOS, we worked closely to align their cutting-edge technology with emerging sustainability opportunities—specifically around green mortgages. We explored how FintechOS could help financial institutions collect and leverage home energy data to better assess energy efficiency and potential savings, enabling banks to decarbonise their mortgage portfolios and advance toward Net Zero targets. This collaboration highlighted how sustainability can be embedded into commercial strategy, driving both impact and innovation.

Investing in early-stage UK companies driving change through Consumer Health and Sustainable Consumption.

Eka Ventures
Location: London, UK
Sector: Consumer
Eka Ventures invests in early-stage UK companies which leverage consumer technology to enable positive system change. Within this strategy, they focus on two themes: Consumer Health and Sustainable Consumption, defined as:
Consumer Health: companies which enable the shift from a treatment driven healthcare system to a holistic and preventative system that improves access to the determinants of health, improves population level health and reduces health inequality.
Sustainable Consumption: companies which enable the transition from linear supply chains to efficient, circular, decarbonised supply chains across each consumer industry.
Impact is tightly integrated across sourcing, diligence, and portfolio management.
Sourcing is underpinned by data, research and network. Eka’s internal Data Platform screened 75,000 companies in 2024 and identifies those that fit within the two impact themes outlined above. Research enables Eka to conduct thematic deep dives on impact topic areas like Health x AI, Climate x Insurance, and Consumer x Impact. Their network is amplified through impact-specific events aimed at investors, founders, and angels.
Impact is integrated throughout the diligence process, using a combination of expert calls, financial modelling, and impact assessment. This allows Eka to create a Shared Value framework for each company which demonstrates how impact and commercial growth occur in lockstep.
The portfolio management stage involves automated reporting of impact key performance indicators, reported on a quarterly basis through Quarterly Investor Reports as well as on an annual basis, through Eka’s Impact Report, in greater depth. These KPIs are then aggregated across their portfolio companies to roll into broader fund-level impact goals.

Helping drug makers digitise, automate, and scale medicine development with AI- and physics-powered process modelling that accelerates R&D by over 90%.

Polymodels Hub
Location: London, UK
Sector: Digital Health & Wellness
Medicine has advanced considerably in the last few hundred years but the sector remains ripe for disruption particularly for digital innovation. Every stage of the pharmaceutical development process carries the risk of a product in development failing due to issues with efficiency and/or efficacy. Additionally, the cost of pharmaceutical development is reflected in the high pharmaceutical prices charged to payers and national health agencies decreasing accessibility to potentially life-saving medications.
It was with this social issue in mind that Molten invested in PolyModels Hub, an Al based process design software that enables pharmaceutical development teams to digitalise the process development step of pharmaceutical product development reducing the need for lengthy testing phases and use of resources to conduct these. This reduces time to market and the costs associated with pharmaceutical R&D while simultaneously increasing the chances of molecules discovered being finalised into pharmaceuticals. As a result, PolyModels is increasing the chances of life-saving medicines being brought to market faster and at lower cost.
PolyModels' impact is not limited only to increasing affordability and accessibility of pharmaceuticals as digitalisation of process design in pharmaceutical development reduces resource consumption and hence environmental impact of this step. While still in the early stages of development, PolyModels demonstrates Molten's endeavours to back innovative solutions that generate impact not just for their users but also for wider stakeholders.

Leveraging AI and a global network of expert pathologists to deliver rapid, accurate diagnostics that improve patient outcomes and accelerate drug development.

Deciphex
Location: London, UK
Sector: Digital Health & Wellness
Leverages AI and a global network of expert pathologists to deliver rapid,
accessible, innovative pathology services that improve patient outcomes.
Deciphex operates Diagnexia, an AI-augmented pathology platform that gives healthcare systems on-demand access to a global network of 250+ subspecialist pathologists. Over 70% of treatment decisions depend on a pathology report, yet 97% of NHS histopathology departments operate below safe staffing levels and the global workforce is contracting, with parts of sub-Saharan Africa served by approximately one pathologist per million people. Training a replacement pathologist takes 12–15 years; there is no recruitment solution.
Deciphex’s largest sustainability impact is closing this gap. In 2025 the platform processed over 147,000 clinical cases at an average turnaround of 1.1 days. In NHS trusts including Bedfordshire Hospitals and East Sussex Healthcare, reporting wait times have fallen from two months to two days, directly improving cancer pathway timelines and patient outcomes.
Through carrying out its sustainability-linked risk and opportunity assessment, Molten aimed to ensure that social impact is preserved and remains a core part of the company’s growth strategy, thereby creating a long-term competitive advantage for Deciphex by identifying areas of high need where a solution like Diagnexia would be able to have real impact on healthcare outcomes.
