Cosysense raises £1.5m pre-seed to cut commercial building energy use with sensors
This article covers Cosysense, an energy startup, which has raised £1.5m in an angel and pre-seed round to expand a suite of tools aimed at improving energy efficiency, occupant comfort and operational performance across commercial buildings. The funding and public innovation support aim to help landlords, facilities managers and corporate occupiers reduce energy use and operational costs as part of efforts to decarbonise the built environment.
Cosysense, an energy startup, has raised £1.5 million in an angel and pre-seed round to expand a suite of tools aimed at improving energy efficiency, occupant comfort and operational performance across commercial buildings. The raise, which includes public innovation support, matters because better data and automation in buildings can cut energy use and operational costs as the UK pursues its net zero goals.
Why it matters
The built environment remains a central target for emissions reduction and cost savings in the UK. Solutions that deliver measurable energy savings while maintaining occupant comfort can help landlords, facilities managers and corporate occupiers meet regulatory and voluntary net zero commitments.
Cosysense’s funding round also signals continued appetite for proptech and energy-focused innovation that combines hardware, analytics and control. Public support from innovation programmes ties the company’s ambitions to broader UK policy efforts to accelerate low-carbon building technologies.
Inside the product
Cosysense positions itself as a provider of data-driven insights and intelligent automation for buildings. The company says its technology helps building owners and operators identify energy waste, optimise comfort and improve operational performance — a mix of monitoring, analytics and automated control aimed at creating more efficient, profitable spaces.
The founding team began prototyping during the Young Leaders of the Americas Initiative at Miami Dade College in 2023. Since then, Cosysense has worked with academic and technology organisations to develop its offering and prepare for customer deployment.
Who are the investors?
The round was led by Bethnal Green Ventures. Other participants named in the announcement include Cambridge Enterprise, SyndicateRoom and institutional investors associated with Cranfield University. Cosysense also received support from Innovate UK through its Net Zero Living and Investor Partnerships programmes.
Notable angel backers listed are André P., Rob Dobson and Jordi Goetstouwers Odena.
The company has opened a second tranche to the round with the intention of oversubscribing and is looking for investors who can add strategic value in proptech and energy efficiency.

Founder perspective
The founders credited a network of partners and mentors with helping them reach this milestone. Organisations singled out include Funding London (represented by Frank Herkströter), Mountside Ventures, Imperial College London, Undaunted, Digital Catapult, Energy Systems Catapult and Alan Martin Engineering. These groups typically provide a mix of investor introductions, technical validation and market development support, which founders say has been important during product development.
The bigger picture
Cosysense’s funding sits at the intersection of two trends: growing investor interest in technologies that decarbonise buildings, and increased public backing for early-stage clean energy innovation. Innovate UK’s involvement links the round to national programmes that aim to de-risk early commercialisation of net zero solutions.
If Cosysense can convert pilot data into repeatable customer outcomes, it will join a wider cohort of UK and European startups pitching operational energy savings to property owners and managers. That market remains competitive, but the combination of private and public funding in this round underlines that UK energy investors are still prepared to back companies addressing building efficiency.
The raise also highlights how university spinouts, innovation centres and accelerator networks continue to feed the pipeline of energy and proptech innovation across the UK and into European markets.
