Concrete4Change raises £2.5M to permanently lock away CO2 in concrete
Concrete4Change (C4C), an advanced materials company that permanently captures and utilises CO2 by mineralising it in concrete, has raised £2.5M in seed funding. The round was led by Zacua Ventures, an early-stage venture fund focused on the built environment and Counteract, a carbon removals focused venture fund, with participation from the family office of Goldbeck.
Founded by Dr. Sid Pourfalah, Dr. Michael Wise and Dalraj Nijjar, C4C has developed a novel proprietary technology that permanently captures CO2 and mineralises it in concrete. CO2 is captured by C4C’s carrier material, and the loaded material is mixed in fresh concrete as an additive. The CO2 in the concrete undergoes a chemical reaction and is permanently mineralised. The result is concrete that is not only 20% stronger but becomes a CO2 sink that prevents any leak, even after demolition of the concrete.
Approximately four billion tonnes of cement is produced annually which creates three billion tonnes of CO2 per year, equating to 8% of global CO2 emissions. C4C plans to create localised supply chains by taking advantage of low-cost waste streams such as the CO2 emitted at cement production sites. C4C’s technology for CO2 mineralisation is completely novel in the market - using a carrier material medium to transfer CO2 into concrete with the aim of making it stronger and greener as a result. It is applicable to all types of cement and concrete including pre-cast and ready-mix concrete and can be easily incorporated into existing supply chains.
“This fresh injection of funding from specialist investors with deep sector expertise means we can now go from successful demonstrations in the lab and small-scale trials to real-world pilot projects.” says Dalraj Nijjar, Co-founder & Chief Commercial Officer of Concrete4Change.
Setmixer raises £600K in Seed round to launch AI-assisted music mixing tool
UK-based Setmixer, a platform that allows artists to record and mix their live performances with studio quality, announced today that it raised £600K in funding in a seed round led by Raw Ventures. The proceeds will be used to launch their AI-assisted mixing process, which creates a perfect result for instant releases and prevents live performances from being lost for life.
The startup creates the unique opportunity for live performances to be recorded in full multitrack studio quality and mixed through their instant automix process. Its smart recorder is permanently connected to the mixing desk of partner venues, ensuring that every performing artist is captured in up to 64-channel studio quality. In 2023, Setmixer recorded over 10,000 hours of live music in full multitrack studio quality, equivalent to 1.15 years. The company was founded by Pascal de Mul, who brings extensive experience from multiple media juggernauts, including Spotify and Deezer.
The launch addresses a significant challenge in the music scene, which is the transience of performances. PwC found that music in physical formats is in decline, and revenue will continue on a downward trend. At the same time, music available in digital formats will increase its share of recorded music revenue, rising from 74.3% in 2022 to 80.7% in 2027.
“This milestone is a testament to the unwavering dedication of our remarkable team at Setmixer, and it's also a nod to the extraordinary community of artists who have played their hearts out for their fans in 7.4 million live music performances worldwide.”says Pascal de Mul, founder and CEO of Setmixer
Metris Energy raises £2M to ‘power up’ the UK’s £22B solar economy
Metris, the first AI-powered solar energy platform for commercial property owners, has raised £2M in a pre-Seed funding round led by Octopus Ventures and Aenu VC to revolutionise how property owners assess, install, and monetise solar energy within their portfolios.
Co-founded by ex-Octopus VC Natasha Jones and software engineer and serial startup founder William Whatley, Metris has created an end-to-end software solution which streamlines and automates the solar energy transition for commercial property owners and enables them to monetise their solar energy whilst cutting carbon emissions.
Solar energy generation within the commercial property sector represents a £22B revenue opportunity. Yet the complex processes involved in the solar adoption journey – from calculating projected revenue to agreeing energy contracts with tenants – has historically prevented commercial property owners from realising their portfolio’s full solar potential. Metris is the first AI-powered “solar economy” platform created specifically to help commercial real estate owners overcome this hurdle and reap the rewards of solar energy adoption, improved energy resilience and tighter energy security.

Plural doubles down on founder investment model with new £342.41M fund to back Europe’s most ambitious founders
Plural, the early-stage investment fund set up by founders and operators, today announces a new £342.41M fund to back the most ambitious founders on a mission to change the world through technology. The fresh capital, raised just 18 months after the debut fund, continues Plural’s momentum following its first 26 investments, the expansion of the investment and platform scaling team and significant appetite from sophisticated LPs to invest in Plural’s unique model.
Plural launched in June 2022 with the aim to give serious founders in Europe investors with experience to match their ambition. Only 8% of European VCs have built a company before, yet founders building hard companies will be better served by investors with first-hand experience.
Plural defies traditional industry norms, whether that’s being amongst the biggest investors in the fund, not charging any deal costs to portfolio companies, or having serious skin in the game with each Plural investor doubling down by co-investing a meaningful amount of their personal wealth in each investment they lead, in addition to deep time. Plural also places a strong focus on ensuring its LPs reflect its core values, and, notably, nearly half of the capital raised comes from university endowments, philanthropic foundations and causes, demonstrating a strong alignment between the missions Plural backs and the capital it invests and returns.
