About Us - Weedingtech NZ



Set up in 2011, Weedingtech’s primary objective was to provide organisations with a sustainable solution for communities to manage their outside spaces, whilst also protecting their residents and the world around them. Our answer was to develop Foamstream, the best alternative solution possible for those wanting to move away from traditional herbicides such as glyphosate.


“At Weedingtech we care passionately about the world we live in. That’s why we developed Foamstream: the world’s leading herbicide-free weed control technology – so we can make the reduction of herbicide use and the protection of our planet a reality.

Using Foamstream you can control unwanted vegetation in a cost-effective, efficient and safe way, whatever your environmental credentials and regardless of legislation. And you can do so much more with it now too – from chewing gum removal, to street cleaning, to power washing and general sanitisation jobs.”

Leo de Montaignac, CEO

Co-founder of Weedingtech, I’m a keen fly fisherman, foodie and globe trotter. Starting my career in finance, my passion for the environment and the clean-tech sector led me away from the City and in to working on IP commercialisation for start-up businesses in the cleantech space. Initially responsible for setting up key supplier relationships, I now develop our distribution networks across North America and Australasia, showing the world that the status-quo in weed control can ultimately become herbicide-free.

Interested in everything, I make sure Weedingtech machines fulfil all the needs of our customers and remain at the forefront of the ever-evolving technological landscape. I enjoy crafting the path from idea inception through to product fruition while solving the challenges that it presents. When not working I can be found practicing various competitive martial arts, scuba diving or enjoying life with family and friends – preferably around delicious (French) food and wine.

Having consulted for numerous companies across the world, Weedingtech has always stood out for me as being an innovative company, with a can-do approach and a fun team to be part of. Having made the easy decision to join them, I now make sure we are continually evolving our operating model to ensure we can deliver the best product and customer experience in the market. I enjoy seeing strategic ideas through to implementation. When not working, I can be found in the middle of a wet, muddy field coaching youth football, road cycling, or on a golf course (normally playing from sand).
