“Disinfection robots, cleaning robots, e-commerce delivery robots…I see a lot of opportunities”: Interview with Accerion’s founder Willem-Jan Lamers

Many industries have been impacted by the pandemic in one way or another. Food delivery apps have boomed, while ride-sharing services dropped by 70% in the past months. We have been wondering what has changed for the mobile robots and logistics sector. How did the increase in online shopping orders influence the logistics sector? Will mobile robots be used more because of the restrictive measures?

To find the answers to these and other questions, we spoke with Willem-Jan Lamers, founder of Accerion. Accerion (2015) is a Dutch company which produces localisation technology to enable mobile robots to become truly autonomous. We discussed with Willem-Jan the future of autonomous mobile robot sector, the effect of the pandemic on logistics and what makes Accerion localisation technology so unique.

First up, let’s start with the basics. How did you start Accerion and what is your mission with the mobile robot’s localisation technology?

It all started with an invention in my first company called Venamics in 2012. After 3 years of market research and development, we found the perfect fit for our technology in the mobile robotics market. It was then, in 2015 that Accerion was founded. In early 2016, my business partner Vincent Burg and our first employee Talha Ali Arslan joined me. We received our first investment which helped us to expand the team, develop the first products and attract customers. Last year we landed our Series A investment round and we grew the team to 20 people and 40 corporate customers all over the world.

The mission of Accerion is to make autonomous mobile robots 100% independent from infrastructure and give them the ability to operate in a flexible and dynamic environment, specifically in warehouse logistics and production automation. To make it happen, we developed a novel localization technology. It works with the use of cameras that look at the ground surface beneath the robots, using it as their reference. The floor is a static reference that does not change quickly, and by analysing the scans of the ground surface, the robots can localise themselves in the environment. This is what makes our approach so powerful and unique.

What are the principle markets you work with, and how have they been affected by the COVID crisis?

Our customers are autonomous robot manufacturers who, in turn, sell robots to the end user, mainly in logistics and production automation, but also in entertainment, agriculture and other adjacent markets. The principal market is indoor logistics and production automation. With regard to business activity, we are now almost back to the situation before the pandemic. We have clients from all over the world, including Europe (the Netherlands, Germany, Spain, Denmark), the US, China and India, who keep placing orders. Actually, the logistics sector has been booming at the moment and according to the analysts, the autonomous mobile robot market will grow faster that had been expected before the pandemic.

You work in the Netherlands where the restrictive measures were rather moderate compared to other European countries. How has the new business set up worked for Accerion?

Overall, the new business setup working remotely, was good for the company. To provide some context, our HQ is in Venlo, in the south of the Netherlands and when the Dutch government introduced the recommendations to work remotely in the middle of March, our team immediately took action and within one weekend, we adapted all the processes (including IT-related processes) to the new work-from-home environment. Regarding the general net effect on the business, I also noticed that the team became more efficient and focused working from home spending less time on travelling. However, the biggest drawback for us is the difficulty in meeting the customers face-to-face.










What are your predictions about the usage of mobile robots in the future, especially considering the ‘new normal’ setup?

I see a lot of opportunities in the current crisis for the growth of mobile robotics market. For instance, disinfection robots, cleaning robots, robots for logistics processes optimization, e-commerce delivery robots. I see a lot of opportunities in the area of disinfection robots linked to the current changes and shift to so-called ‘a high-mixed’ environment where robots and people work together with the goal to reduce tactile exposure of goods and robots with people. The e-commerce market has grown a lot – more goods are shipped door-to-door and most likely, this trend will continue.

What are the main challenges in the autonomous mobile robot sector?

Operations are becoming more flexible, dynamic, fast-paced. The currents trends include space optimization, products customization and goods diversification. All of that pose certain challenges to the logistics processes and requires a high degree of flexibility and adaptability. For the autonomous mobility sector, it means the increasing importance of an easy identification of the robot’s location and its complete independence from the environment.

What is your opinion on a common belief that robots are taking over the world and soon humans will be out of jobs?

It is funny how often this question pops up. In my view, this concern is absolute nonsense. It comes from the media and is based on the fear of new technologies. A century ago, people were afraid to switch from horses to cars and it seem to have worked quite well. So, there is nothing to be scared about. I believe that robots will take over the heavy, repetitive, ‘boring’ work which humans are not eager to do, such that they can focus on the interesting and more challenging work. For example, in many logistics applications it already becomes a requirement for robots to accomplish certain tasks because of the lack of the employees.

What advice would you give to early stage, European, tech startups right now?

Here are my 2 main recommendations:

  1. Validate your hypothesis about your product and its fit to the market. Build the smallest prototype to show it to your customers and validate it with them. Talk as much as you can with your potential customers, preferably doing it face-to-face. Tune your product in to the market. Listen to them. Be as lean as possible.
  2. Focus. Focus on the market you want to address and the product you are developing. There will always be tremendous opportunities popping up around you. The biggest mistake most entrepreneurs make is diving into every opportunity that arises. I recommend not to be distracted by new opportunities which make you deviate from your path. Focus on one task and keep working on it.

How Much Time To Spend “Cleaning” A B2C App?

I'm a software developer with a full-time job at a megacorp in the digital marketing space. However, I've been working off and on on a B2C phone app during nights for the last 5-6 months. I haven't gotten much feedback from potential users so far. I think fills a niche that others in the space are ignoring. I also think that I would use the app myself.

I think that I have a minimal viable product done where the product will provide the substantial value that I hoped. I think that I want to get feedback from other people on the user flow and user experience. There some rough areas of improvement that I still want to do. But, I don't know if I should get more feedback before I jump in to fixing those areas.

My impression of B2C is that users are generally less forgiving of unintuitive user interfaces and the experience needs to be tuned quite a bit more than if you were making B2B software. Otherwise, I could be throwing marketing money and time at these users that would get lost in an unintuitive flow.

I've thought that my next step at this point would be to create internal builds in the app store and share them with people I know to get feedback from them.

What's the best way to collect feedback from after that process? Is responding to app store comments the best way? Or should I have an internal-to-app mechanism to collect feedback? Is there any general advice from others who have launched B2C phone apps and been in this position? What do you wish you'd done?

As a side question, the app requires a "network" of people geographically close to you for it to work well. My plan was to buy paid ads (likely Facebook ads) to get people to join and throw money at user adoption. I make quite a bit of money in my day job and am already financially independent and think I could throw a lot of money at ads if I wanted to. This is in lieu of seeking investment capital or looking for another co founder that would do marketing. I've had so many bad experiences with other potential co founders that I'd rather just avoid finding someone and go alone until I know i find the right person. I also hear a lot that if you don't have a co founder, you're likely to fail. Do I need to go find someone for the sake of having a co founder?

Thanks in advance for any help.

The Best Commercial Cleaning Services

Cleaning and sanitizing a business requires a lot more work than simply straightening up around the house. Whether you run a small retail store or a company with hundreds of employees, you need a professional cleaning service that has the staff, resources, and materials to handle a big job.

In other words, you need a commercial cleaner. While most of them operate nationwide, it’s common for them to franchise. Much like the chain fast food restaurants in your neighborhood look and feel like every other location around the country, they’re owned by a local person who follows corporate rules and regulations.

So how do you find a good commercial cleaning service? Fortunately, there are plenty to choose from. Even better, most have been in business for decades. These big national cleaners can handle everything from vacuuming your company’s carpets to sanitizing surfaces after a viral outbreak.

How to Choose the Best Commercial Cleaning Service for You

Commercial cleaning can be a pricey addition to your business’s budget, so you want to make sure you get the most value for your investment.

And that’s exactly how you should view commercial cleaning services: as an investment. Ideally, you want to find a cleaner you can work with over the long haul. That way, you’re not constantly getting quotes and dealing with a revolving door of cleaning crews.

So what should you look for in a commercial cleaning service? What kinds of criteria should you use to measure the various companies side by side? Here are five tips for picking a cleaner that will keep your business sanitized and healthy for your employees and customers.

1.  Experience

Look for a commercial cleaner that’s both reliable and knows your business. This means you want to look for a company that’s been around for at least several years. Fortunately, the majority of national cleaning companies have decades of experience under their belts, so this shouldn’t be an issue.

However, also make sure the cleaning service has experience handling your type of business. Some commercial cleaners are known for their excellent work in a medical setting. While they might be perfectly capable of cleaning your 10-person office, do you really need that level of cleaning? Furthermore, are you prepared to pay for it?

In this case, you’re probably just fine going with a cleaning service that focuses on retail stores or office buildings.

2. Availability and Flexibility

What kind of hours is the cleaning service willing to work? Does it charge more if you request a nighttime cleaning?

The reality is that most businesses don’t want a cleaning crew coming through in the middle of the workday. Not only is this disruptive to employees, but it can be a major turn off and inconvenience for customers.

A good commercial cleaning service will accommodate your schedule rather than trying to strongarm you into working around theirs.

The majority of national commercial cleaners state explicitly that they offer nighttime cleaning as a standard service.

3. Scope of Services

When you hire a commercial cleaner, you’ll often save money by combining two or more services. For example, many commercial cleaning companies offer janitorial services as well as cleaning. It’s also common to see cleaners provide regular maintenance cleaning along with more in-depth cleaning on a quarterly or semiannual basis.

Think about the cleaning tasks your office needs and what makes your facility unique. Do you have industrial work areas that gather a lot of dust or debris? Or maybe your office building features dozens of windows that require regular cleaning. These are all considerations you should take into account when looking for a commercial cleaner.

4. Supplies and Equipment

If you’ve ever hired a residential cleaner, you might have encountered a service that required you to supply the cleaning products and equipment. This isn’t something you want in a commercial setting. For one thing, the cleaners required to achieve a deep clean or a hospital-grade sanitation usually need to be stored in specific temperatures and under certain conditions.

Also, most business owners don’t have time to source a large volume of cleaning supplies and equipment, price it out, and manage the inventory needed for an entire office building or business with multiple locations.

A good commercial cleaning service will have its own cleaning products and equipment, and its workers will be trained on their proper use.

Additionally, many commercial cleaning services offer green or eco-friendly cleaning services that use plant-based cleaning solutions. If this is important to you and your business, ask a commercial cleaner what kind of products it uses, if it carries any environmental certifications, and if it’s willing to provide you with a list of ingredients in its products.

5. Trustworthiness

Most commercial cleaning services do their work at night. This means they’ll need to work inside your building when employees are absent and the office is closed to the public. You want to make sure you contract with a commercial cleaner that employs reliable and trustworthy professionals.

If your business handles sensitive records, such as patient information or customers’ financial account data, you need to know you’re working with cleaners who will take appropriate steps to protect records and documents.

You should also verify that the commercial cleaning service is insured. That way, you’re not responsible for any injuries a cleaner suffers while working on your property.


Life gets messy, whether you’re at work or at home. In a business setting, foot traffic and product production can create industrial size messes. Fortunately, commercial cleaning services have the manpower and resources to tackle even the biggest jobs. If you do your homework and take time to get a few quotes, you can find a commercial cleaning service that eases the burden of keeping your business in top shape.
