Greyparrot.ai Secures £24.3m Series B to Advance AI-Powered Waste Analytics

London-based Greyparrot.ai Ltd, a specialist in AI-powered waste analytics, has successfully closed a Series B funding round, raising an estimated £24.3m. The funding, with an allotment date of 17 March 2026 and filing date of 15 April 2026, marks a significant step for the company as it continues to innovate in the waste management sector.

Founded on 30 November 2018, Greyparrot.ai addresses a critical challenge in the recycling industry: the lack of real-time data and insights into waste composition. The company’s core offering revolves around its Greyparrot Analyzer units, which leverage advanced computer vision technology to identify and analyse waste streams on conveyor belts within recycling facilities. This technology provides waste professionals, packaging producers, and regulators with real-time data on material types, brands, and financial value, ultimately aiming to enhance recycling efficiency and improve resource recovery. Greyparrot's mission is to increase resource recovery by providing real-time waste intelligence. The company offers solutions such as object recognition-enabled smart bins, waste composition monitoring, and software-based robots for automated waste sorting.

The latest £24.3m Series B round represents a substantial increase in capital for Greyparrot.ai compared to its previous funding activities. The company has a history of securing investment across several tranches, primarily in Series A rounds. Prior to this Series B, Greyparrot.ai raised a total of £8.8m across multiple Series A and earlier rounds. These included a £281.3k round in February 2019, followed by £256.3k in June 2019, and £250k in February 2020. Further investments in 2020 saw the company raise £2.8m in July and £25k in November. More recently, Series A rounds included £5.6m in May 2022, £25k in September 2022, £2m in December 2022, and £386.4k in April 2025. The current Series B round signifies a strong investor confidence in the company's growth trajectory and its impact on the circular economy.

In conjunction with the latest funding, Omar Iqtidar Mir was appointed as a director to Greyparrot.ai Ltd on 17 March 2026.

This funding round for Greyparrot.ai comes at a dynamic time for the UK's deep tech and climate tech sectors. The broader UK deep tech ecosystem has demonstrated robust growth, attracting $43.7 billion in venture capital since 2019, positioning it as the third-largest globally behind the United States and China. In 2025, the deep tech sector raised $5.9 billion, making it the second-best funding year on record and representing 31% of all UK venture capital funding.

Within the climate tech landscape, which Greyparrot.ai's operations align with, investment reached $1.9 billion in 2025, a decrease from its $3.8 billion peak in 2023. However, this decline is largely attributed to fewer "mega-deals" (rounds over $100 million), with underlying funding activity, particularly at the Seed and Series A stages, remaining relatively stable. A key challenge identified in the UK climate tech sector is a "scaling gap" at Series B and beyond, where promising companies struggle to access the capital needed for commercialisation and rapid deployment. Greyparrot.ai's successful Series B round, therefore, stands out as a positive indicator in addressing this scaling challenge within its specific niche.

Investment in the UK climate tech sector is heavily concentrated in London, which received 66% of all funding in 2024. Greyparrot.ai, being based in London, benefits from this concentration of capital. Furthermore, solid waste management has seen significant cumulative funding, reaching $730 million, underscoring its importance within the broader climate tech landscape.

Artificial intelligence, which is central to Greyparrot.ai's technology, has emerged as a dominant force in UK venture capital. AI startups collectively raised over £6 billion in 2025, accounting for more than a third of all UK venture capital. This surge highlights a decisive shift towards technologies with clear commercial readiness and global scaling potential. The waste, recycling, and circular economy sector, in particular, is experiencing a significant transformation driven by AI. Waste management firms are increasingly adopting AI, IoT, and sensor technologies to automate sorting, improve efficiency, and reduce operational costs. This technological innovation is expected to be a defining investment theme in 2026, with AI-driven waste systems offering significant opportunities for investors. Greyparrot.ai's focus on AI-powered waste analytics positions it well within these converging trends of deep tech innovation, climate tech investment, and the increasing adoption of AI in waste management.
