Hartenlust Group successfully merges its asset “Troostwijk Auctions” with “BVA Auctions”.

Hartenlust Group successfully merges its asset “Troostwijk Auctions” with “BVA Auctions”.


Xeno Grimmelt, one of the two founders and partner of Hartenlust Group, states that Bencis Capital Partners and Hartenlust Group worked together in good cooperation with both management teams in order to bring the two European market leaders in auctioning together. Xeno Grimmelt: “we were looking at this opportunity from the start. We believe that consolidation of professional auctioning platforms is a logical next step. Transforming auctioning from traditional offline and inefficient exchanges into scalable online tech companies, being able to connect sellers and buyers from all over the world in a transparent and efficient way instead of working from a Rolodex, has been the name of the game the last decade. The next step to grow faster and assure best customer satisfaction is to combine IT budgets, client bases, vertical expertise and last but definitely not least scarce skilled resources who truly understand the business of our clients and create the best, tailor made way to turn assets into liquidity”.


Market studies show that auctioning – as a way of selling – is growing fast compared to direct sales between sellers and buyers. Market places bring these parties together but are less transaction driven than auctioning platforms. Xeno Grimmelt: “the rules of engagement of marketplaces are often unclear and lack track record, also because the screening of assets, sellers and buyers is not done properly on a marketplace. That is also causing the difference in charged service fees by market places and auction platforms. The more effort and expertise, the higher the result, one could say.”


Troostwijk and BVA have built up a strong business in the Netherlands and Belgium. Growth opportunities for this new combination lie especially in Germany where both companies have strong footholds with Dechow and Troostwijk Germany. And since professional auctioning as a way of turning assets into liquidity is conquering the rest of Europe, the existing footprint in 18 European countries seems ready for it!


Hartenlust wishes the new combination and its management lots of success with this new challenge.


Official press release

Troostwijk and BVA merge – “Joining forces to create Europe’s best online auction platform”


Auctio, with Dutch BVA Auctions as its best known online auction house, and Troostwijk Auctions & Valuations have announced they will merge to form Europe’s largest online auction platform. “A logical step”, say CEOs Ghislaine Duijmelings (Troostwijk) and Herberth Samsom (Auctio). “We are merging our technologies, auction expertise and market knowledge. Our buyers will now find even more items that interest them. And our sellers will instantly reach an even larger, more international buying public. Our experts know exactly where to find the right buyers.”


One company, multiple houses
“Technology, data and marketing are increasingly relevant to auctioning. We are now pooling our expertise and investments into holding company TBAuctions”, says Samsom. “Troostwijk and BVA will continue to be our primary houses. We are a perfect match: together, we have something for every buyer. We take a data-driven approach to determine what house and which channels will allow us to achieve the best result.”


“We currently auction over 1.5 million items (lots) each year, in over 6,700 auctions. We have offices in 18 countries, and our buyers come from all over the world. Every month, we receive more than 6 million visitors and almost 100 million pageviews. Buying and placing bids securely are major concerns for buyers. We’re an excellent alternative to regular sales channels: that’s because we offer buyers a huge selection along with the thrill of the bidding process.”


A genuine partner
Duijmelings: “Another one of our strengths is the personal approach we take towards our partners. For example, we help companies achieve their overarching goals: to be a healthier business, to create space for investing and reinvesting and to become more flexible so they can keep on top of market developments. All of this is easier when you have a trusted partner who helps you capitalize on the value of your assets – because everything has value.”


Focus on specific sectors
The company is sharpening its focus on specific industries and growth sectors throughout Europe. To name a few: art and antiques; real estate; agriculture; metalworking; food-processing; construction; infrastructure; logistics and transport. Samsom: “Auctions are still a relatively new way of selling in some countries and industry sectors. We want to reach these sectors and firmly establish auctioning as the ultimate way to sell. Our 350-member team is ready to help them cash in on the value of their assets.”


About TBAuctions
With its flagship online auction houses Troostwijk Auctions & Valuations and BVA Auctions, TBAuctions is the largest online auctioning platform in Europe.

This week Wunderman announced it has acquired a majority stake in Emark, the marketing technology performance company that delivers marketing and advertising technology solutions for data-driven and personalized customer interaction. Emark will help further strengthen the agency’s growing global Salesforce practice.


Emark delivers Salesforce Marketing Cloud, Commerce Cloud, Service Cloud, DMP, and advertising technology such as Facebook Advertising and Google Ads, as a single, integrated solution.

Hartenlust celebrates lift off of first global IOT-connectivity network

Hartenlust celebrates lift off of first global IOT-connectivity network


Nano-Satellites to power IoT projects in the 90% of the world currently without connectivity, including British Antarctic Survey.


Sriharikota, India. | 29 November, 2018 | Since 2017 Hartenlust Group participates in ‘NewSpace’* startup Hiber and now they celebrate the lift-off of their first HiberBand nano-satellite on Thursday 29th November at the Satish Dhawan Space Centre in Sriharikota, India. Dutch-government backed Hiber will be the first truly global satellite solution, bringing IoT connectivity to the vast majority of the world which is currently lacking a network.


Less than 10% of the globe is covered by IoT-ready connectivity, with existing networks (such as WIFI and LPWAN) favouring urban areas and wealthier countries, whilst traditional satellites that provide wider coverage are expensive and power hungry. For these reasons, many IoT applications and services are not currently economically viable – for example, monitoring soil moisture to improve production efficiency and crop quality in the third world countries that rely on farming the most. Hiber is launching into the orbit to change that.


Once fully operational, the nano-satellite will fly over earth’s poles 16 times a day and the equator twice a day, providing our planet with IoT-connectivity. Using a process that is up to 20 times cheaper than existing global solutions, it works by transferring data from modems and antennas owned by customers directly to the micro-satellites. Data packets are then sent back to earth via the two existing satellite stations in Spitsbergen in Norway and Delft in the Netherlands.


The network will be commercially operational from Q1 2019, serving more than 25 pilot customers. Hiber estimates there is a potential £3.5Bn opportunity for growth as potential IoT projects falter due to a lack of connectivity. One of Hiber’s pilot customers, the British Antarctic Survey, will be using the network to transmit data from remote measurement stations currently lacking satellite communications. The ability to stream data from the stations will result in more frequent information gathering at a lower cost and the strain on the environment will be reduced as visits are lessened.


Xeno Grimmelt, supervisory member of Hiber and co-owner of Hartenlust Group (one of Hibers’ lead investors), states: “Hiber operationalizes cheap and sustainable access to all your assets on the planet. Connecting all kinds of data-sensors in the world fulfills a fast growing global need. One that delivers new, specific and essential value for every single user/owner, from manufacturers to insurance- or trading/transportation companies and from governments to local farmers. Breakthrough technology, a scalable setup and protocol, and the tremendous appetite for success of this experienced leadership-team supports this venture. Although we use advanced space technology, Hiber will look more like a global digital data network operator, where low cost and secured, reliable service for our customers is key”.


Other customers include a Dutch company which will be bringing climate stations to schools in rural communities in Peru, Tanzania and Sri Lanka to educate tomorrow’s smart farmers and Blik Sensing, which helps manage water resources by providing insight into global groundwater levels.


Hiber has already partnered with Amazon Web Services, IBM Watson and Actility for easy integration into existing cloud services, allowing customer to easily build unique applications with global data-streaming capabilities.


“It is beyond exciting to be the first company bringing full IoT-connectivity to the globe – as well as being the first ever commercial Dutch Satellite operator,” said Laurens Groenendijk, Co-Founder of Hiber (and Co-Founder of JustEat and Treatwell). The commercial applications for Hiberband in the IoT-industry are limitless. We look forward to powering diverse projects, from tracking cattle to tackling climate change and more effectively growing crops.”


The launch of the first satellite will be followed a few days later by a second satellite at the Vandenberg Air Force Base in California. Hiber expects to launch dozens of satellites to meet the enormous demand for IoT-ready data connectivity around the world in the next 12 to 18 months.


About Hiber

Hiber (formerly Magnitude Space) is a so-called ‘NewSpace’ startup. Founded and led by a dream team of satellite experts and tech entrepreneurs, these ‘Hibernauts’ are literally working on a moonshoot goal: to launch and own a nano-satellite constellation in space. Each nano-satellite will roughly be the size of a large shoebox.


To date, around €10 million in funding has been invested in the company. Thanks to subsidies, innovation loans and informal investors, on 29 November Hiber took its first step towards realising its dream of becoming the Netherlands’ first commercial satellite company. More than 40 employees work on the ground-breaking, patent-pending technology behind Hiber and Hiberband at its offices in Amsterdam and Delft.
