WeedingTech secures £2.2 million Series B investment from Earthworm

We’re delighted to announce that we have just received an investment from the environmental fund manager, Earthworm.

Earthworm only backs companies that have a positive social or environmental impact. Working with a variety of industry professionals across multiple sectors, a core part of Earthworm’s investment ethos is that companies within the Earthworm community must be ethically driven and contribute to the circular economy.

The investment from Earthworm fuels our position as Europe’s leading herbicide-free weed control technology and will help support our continued growth in North America.

The £2.2 million investment has come at a time when the herbicide-free sector is gaining huge traction around the world. The widespread use of traditional chemical herbicides has long been challenged, with international concerns about its impact on the environment and the potential threat it poses to human health.


Recent legislation around herbicides, and their use in built up public spaces, is increasing as the topic comes under ever greater scrutiny from the general public. Governments and regulators are increasingly restricting the use of these chemicals in their cities leaving the organisations that manage those cities in need of new technology.

Leo de Montaignac, our CEO commented on the funding:

“We believe the investment from Earthworm recognises two key things. Firstly, the success Weedingtech has had to date supplying the market with a popular and essential alternative to traditional chemical herbicides. And secondly, the global high-growth potential that the herbicide-free sector holds as organisations increasingly look to reduce their reliance on traditional chemical herbicides.

Weedingtech was founded on very similar values to Earthworm in that we wanted to develop and supply products that benefit the environment. It’s an exciting time to be in this sector and we are delighted to have a new investor who shares our vision and values.”

Investment Manager for Earthworm, Laurence Blair, said of the investment:

“Weedingtech is just the sort of business we are looking to support. It is vital for responsible businesses that are greener, cleaner and safer for the environment to have the opportunity to make their mark.”

Back in 2011 when Weedingtech began, our vision was to create highly-effective, environmentally-friendly systems for managing outside spaces, which are safe to use around people, animals and waterways, and available for organisations who want or need to reduce their reliance on traditional chemical herbicides. This is now the reality as our patented Foamstream process is now used extensively across the Americas, Europe and Australasia with high-profile clients including New York City Parks, The London Borough of Hammersmith and Fulham, The London Borough of Southwark, and Unified School Districts up and down the Californian coast.

LettUs Grow wins £45,000 from Vodafone

LettUs Grow, creator of advanced aeroponic technology and farm management software for indoor farms, has been named one of the UK’s top tech startups at the Vodafone Techstarter awards and won £45,000.


The programme celebrates startups developing and using technology as a force for good. It aims to uncover and develop ideas that harness the power of technology to improve health, education, environmental protection or social mobility.

LettUs Grow will receive £45,000 alongside a 12-month programme of support from Vodafone and the Social Tech Trust – an investor in socially motivated tech.

Humanity must increase food production by 70% to feed an extra 2 billion people by 2050. We must do this with 25% less farmland, depleted soils and an increasingly unstable climate.

To address this problem, LettUs Grow has designed a patent-pending aeroponic system that has shown growth rate increases of over 70% compared to existing solutions for a number of crops. Instead of using soil or water, plant roots are suspended in a nutrient-dense mist. This results in faster growth rates than conventional field growing or hydroponics, consistent and predictable year-round harvests, and a 95% reduction in water usage versus open-field agriculture.

Farms don’t need to use pesticides or herbicides when using LettUs Grow’s technology and by siting farms in densely populated areas, they can reduce the environmental impact of delivering food from plot to plate.

Jack Farmer, one of LettUs Grow’s three founders and operational lead, said: “We’re excited to be working with Vodafone.

“We are very keen to collaborate with them from a technical and a commercial standpoint. That mentorship is really going to help us develop our business.

“We are looking to work with Vodafone and a number of other key partners this year, to implement our hardware and software and deliver profitable pilot farms – in greenhouses, research centres and vertical farms – before then working with these partners to scale nationally and internationally.”

Nick Jeffery, chief executive, Vodafone UK, commented: “The range and calibre of the Vodafone Techstarter winners show that the UK is home to a thriving social tech sector.

“We believe the biggest challenges in society can be addressed using technology and innovation. These awards are just one way we can recognise, celebrate and support startups developing and using technology as a force for good.”

Ed Evans, chief executive of Social Tech Trust, had this to say of the awards: “Vodafone Techstarter is a hugely powerful platform that showcases the potential of partnership and demonstrates how cross-sector organisations can work together to create something truly inspiring.”
