The jury was composed of the following people: Ronald Wielinga from Wetsus, startup coach Frans Nauta and investing expert Ed Flohr.  They selected these startups based on criteria like market opportunities, contribution to sustainability and suitability for the BeStart accelerator. Ronald Wielinga noticed the participants are in a relative advanced stage of their development. ‘They are already quite close to the market and sometimes just need a little push in the right direction to establish substantial growth.’ Project director Mariken Gaanderse is really looking forward to working with these startups: ‘This year’s lineup consists of very strong startups working on a great mix of clean tech themes. ‘

Programme 2020-2021 closes with original DemoDay

What a year it was for our 2020-2021 startups. In spite of the Corona19 setback, which made not only meeting each other more difficult, but also made growing their businesses even harder than it already is, they persevered and kept on working on making this world a cleaner place. So a big shoutout to Dungse, Eatcup, Fertipaq, Powerchainger, Pyrolyze, Sensoty and Wasted!

Concerned cleantech network

The DemoDay on April 12th was a special one. Using a new online tool called, not only the startups had the opportunity to learn. The visitors had to make their way to dedicated startup rooms, where they could meet the founders, spar with them about their most pressing questions, but also talk to each other as if they were meeting each other again after a long time. This led to inspiring and sometimes also hilarious moments. Thanks to our concerned cleantech network for the never ending support to our startups!

Although we let our 2020-2021 batch go as alumni, this doesn’t really mean goodbye. We’ll follow their growth and keep you posted through our social channels and newsletter below on this page.

Looking forward to the 2021-2022 startups

It is almost time for the 6th BeStart year to start. On April 19th we will have a closed event for the candidate startups, from which a jury will chose the most suitable ones for our 2021-2022 accelerator. If you like us to keep you posted, please subscribe to our newsletter below.

April 19th pitch event for candidate startups

On April 19th 2021 in the afternoon the pitch event for candidate clean tech startups will take place at the Kanselarij in Leeuwarden.

If you dream of some result in the future, you have to start working on it today

Last Monday, we had the first session 2021 with our cleantech startups, covering Sales, Efficiency and Human Resources.

Itika Gupta C4 from Dungse commented afterwards: ‘This session really helped us on breaking down our goals. As entrepeneurs at Dungse, we are very good at thinking on the long term: visualising what the future of circularity should look like, creating new ideas, testing them and developing products. Sometimes we lack structure in how to make these plans come true.

If you dream of some result in the future, you have to start working on it today. In this session we got feedback on how to break down our long term goals to actions we can plan for next week or even today. In that way we actually work on our long term goals every day.

Another insight that I had was that Agile working is not only suitable for innovations. We can apply the method to our daily actions, making sure we make money from it in our day to day business.’

Big investment for SG Papertronics after switch to beer market

Our alumnus SG Papertronics will receive a substantial early stage funding from the NV NOM and the University of Groningen Holding Company (RHM) for their mobile lab testing technology.

“The investors believe our tech can be used for several different markets,” explains CEO Maciej Grajewski. “We provide our customers with portable laboratory units that are semi-automatic. They can just use single pods to take to their facilities and test their product without any chemical knowledge.”

In 2019 Maciej enrolled in our programme with two potential business cases: one for the farmer’s market and one for the beer market. “With the help of BeStart we made good progress in terms of understanding the farmer’s market. We found some interesting depencies and really learned how to translate our product to the market in terms of sustainability. We also established some very useful contacts in the region, for example with Anne Jan Zwart from Ecostyle and Joost Paques from the Biobizz hub, who helped us to improve our business thinking. Eventually this helped us prepare to get this investment.”

The switch to the craft beer market in 2020 proves to be a good one. “The difference is not as big as it looks. The concept of portable test units is the same, but brewers would like to use them much more often. Brewers usually test their product on a weekly basis and sometimes more often to control quality and consistency of their product, whereas farmers mostly would test soil (and groundwater) once to three times a year. So we can develop our product with brewers much faster.”

With the help of this investment, the single use testing pod is expected on the dutch market within the coming 24 months. “Our main objective at this point is to bring our device from the lab to brewers and have it tested,” concludes Maciej. “We are already providing services to a couple of breweries and helping them test their samples in their laboratories. This works both ways: we can use their samples to develop our machine and the breweries are getting useful feedback on their product.”

As far as cleantech goes, the SG Papertronics testing unit helps breweries become more sustainable. “The use of raw materials will become more efficient and there will be a lot of savings on ingredients like hop, malt and water.”
