30MHz was founded in 2014 by four engineers. They built a big data platform and wireless sensors to provide smart office, smart industry and smart farming solutions. But it soon became clear that the most impact could be made in horticulture. There is so much untapped potential and room for growth when it comes to digital technology in horticulture. More importantly: we need solutions for sustainable agriculture and food production, and we need them quickly.
That is why, since 2017, the sole focus is on the horticultural sector. We have developed and customised our data platform and wireless infrastructure technologies in close collaboration with leading growers and horticultural research organisations, including Wageningen University, Beekenkamp and Vertify. Today, 30MHz has over 250+ customers across 30 countries in 6 continents and 2500+ platform users, including growers, consultants and researchers.
Team & culture
At 30MHz we work with about 15 highly skilled colleagues. The main incentive for the work we do is to create an impact in the horticulture sector. We all feel responsible for the product and keep improving it as a team. Besides that, we all like to work in a team where you can learn, have great responsibility and have a laugh.
You & 30MHz
As a driven talent, you end up in fertile ground. All the conditions are there for seeds you plant to germinate. Within the dynamic structure of moving from a start-up to a scale-up, you will have every opportunity to grow quickly.
