Yoli
Yoli - an interactive educational block game. Completing tasks and answering questions, the child places cards on the playing board. The cards and board are connected wirelessly, the wrongly chosen card is discarded from the board and the game continues. When the correct answer is obtained, the cards vibrate and bounce.
In addition to the obvious benefits for the child in the development of their attention, imagination, fine motor skills, and interaction with others, Yoli also provides parents with valuable information. Yoli collects statistics which a parent or teacher can access on their phone. As a child plays, even without connecting the phone, statistics continue to be collected and saved. When you are connected, it will be downloaded and available, so that parents can be sure of the completeness of the statistic picture.
This is how adults note game progress; they receive data on how quickly the child solves a particular problem, whether he/she needs prompts (and how many), and which tasks are more difficult for him/her to solve. Yoli makes the learning process fun and interesting for the child and informative for the parent.
How Grinn made a difference
At the very beginning of the project, Grinn engineers developed an electromagnet especially for Yoli; it’s one of the fundamental elements of the toy not yet existing on the market which meets the game’s requirements. In addition to developing hardware, software, testing, and production management, Grinn specialists collaborated with product design developers, which made the final product even more colorful and attractive.

the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I work at sani nudge — we monitor hand hygiene in hospitals and nursing homes. We use an automated system in real-time to track the location of healthcare workers so sanitization happens at the right moments.
What challenge were you trying to address with Grinn?
We didn’t have the internal knowledge to develop the hardware for our product. We had a lot of offers from companies in Denmark to develop it, but they were very expensive and since we began as a startup, we didn’t have a lot of funding. To reduce the cost we looked to Poland to develop our first hardware device.
What was the scope of their involvement?
Grinn develops our main hardware for our IoT devices that monitor the presence of individuals in a hospital, which includes the electronics and firmware that go into the project. I am an electronic engineer and designer, so I supplied Grinn with the business logic and case, product requirements, and some simple prototypes. The prototypes I created gave me some early insights into the development that I was able to share with Grinn.
Together, we developed the concepts further and began the actual development. There were several prototypes completed with rapid prototyping before they delivered the final products. We’ve developed two different devices with them and are currently working on a third.
What is the team composition?
I work with 4–5 teammates depending on where we are in the development phase, but I have two main points of contact.
How did you come to work with Grinn?
We connected through a Danish cooperation partner who helped us with designs in the past and is well versed in the radio communication and protocol we use — they recommended Grinn to us. We realized Grinn had experience developing other applications that had the same hardware components as ours and had the same expertise as the Danish companies, so we decided to hire them.
How much have you invested with them?
We’ve invested about $410,000 with Grinn.
What is the status of this engagement?
We began working with Grinn in March 2017 and the engagement is ongoing.
What evidence can you share that demonstrates the impact of the engagement?
We’ve been able to produce two working devices with Grinn. The first one has been used with patients for about two years now and has had no issues — they’ve provided us with high-quality firmware and hardware.
How did Grinn perform from a project management standpoint?
Even if we don’t contact them every day, they are always accessible. Otherwise, we communicate with them on a weekly basis — if there are any problems, they are involved right away and help us solve them. We have ongoing coordination and communication and they really feel like a direct part of the company.
We work in a scrum and divide testing and retesting responsibility between us. It’s not only their responsibility to set up the project, but also to meet our deadlines, which they do.
What did you find most impressive about them?
They deliver what they promise and the feedback on the concept development we initially did with Grinn was very positive. We have limited resources, and in contrast to larger companies who are very strict about their services because it is costly to develop hardware, Grinn is flexible but firm about the cost of their development services.
Their experience in our industry, including network protocol and Bluetooth, is very impressive. They bring their experiences from other projects to ours, which allows us to quickly find solutions to our issues. They really understand our project and the work that they’re doing for us, from networks to radio communication. They’ve proven that we did a good job hiring them based on their experience — I’m glad I followed my gut and hired them.
Are there any areas they could improve?
I am very happy with their work and our partnership. On our side, we’d like them to do more testing, but that is dependent on whether or not we can get more funding and pay them to take over some of the processes we do internally.
Do you have any advice for potential customers?
I would advise customers to be involved in the business logic as much as possible and to get started with them from the early stages of project development because they have so much expert knowledge.

What did you find most impressive or unique about this company?
Grinn shared their "can do" mentality and their very practical approach to solving problems. Putting attention on important goals/milestones and working together on finding the right solution was something we appreciated.
Are there any areas for improvement or something they could have done differently?
Some of the aspects of the development process were too lean (risk planning, design reviews, testing procedures). However, I expect that those points are handled different after those few years of company growth.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I’m part of the founding team of a small startup located in Denmark.
What challenge were you trying to address with Grinn?
We needed help with software development within the field of Bluetooth and NFC communication. We wanted to find everything we needed in one place so we hired Grinn.
What was the scope of their involvement?
We began our collaboration with Grinn by presenting them with simple mock-ups and prototypes for our electronics, which helped demonstrate the basic functionality of the product. We wanted to build a game for children that has tiles that pop out of a board using electromagnets and permanent magnets, with the tiles being read by NFC technology. The software inside the electronics is based on development kits.
We had whole-day meetings with their electronic software developers creating specifications for the project, minimum requirements, and so on. Many of the things that we needed to do required a lot of research, such as our custom-made electromagnets that needed to work with NFC technology. Grinn delved deep to find out if it was possible to do considering the proximity of strong magnets when doing radio communication.
We kicked off with a one-month sprint, during which Grinn did proof of concept research and investigated the technologies that we needed to use to see if what we wanted was possible. Their team did mock-up tests to figure out how much power would be needed for this project.
We finished the main task, which was the electronics and firmware development, but we still work with Grinn because they are creating other tools for us to use in our production. They also support us for firmware updates so that we’re able to run new types of games.
What is the team composition?
We’ve interacted with a handful of people but I’ve mainly been in touch with two people. There’s a whole team supporting them consisting of electronic designers, software designers, a firmware designer, and a project manager. They also had someone in charge of the visual and the mechanical design portion of the project.
How did you come to work with Grinn?
We received recommendations from other Danish companies and compared all our options, taking into consideration the different cost estimates. We thought that Grinn could handle the task as they had both the electronics and firmware experience to get the product developed. That’s why we chose them.
How much have you invested with them?
We’ve spent between €100,000–€300,000 (approximately $120,000–$370,000 USD).
What is the status of this engagement?
We got in touch with them in December 2019 for the discovery phase and kicked off the project in January 2020. It’s an ongoing partnership. The main project is completed but we’re in touch on a weekly basis.
What evidence can you share that demonstrates the impact of the engagement?
We’re still in the process of getting the product out to the market so we don’t have any hard metrics yet, but everyone from all sides is happy with the product.
How did Grinn perform from a project management standpoint?
I would honestly say that this isn’t their strongest area. We handled the management of the project on our side, but there are other areas where they really shine. It’s the reason why we’d choose them again.
We had weekly online meetings though we did do 4–5 in-person meetings in Poland at the start of the project. We use Slack to communicate.
What did you find most impressive about them?
The people we’ve been working with are very skilled and great at finding solutions to problems. They’re creative and not locked in their way of thinking, completing tasks one way or another.
Are there any areas they could improve?
They could improve on their project management capabilities and maybe provide a better overview of the project status, tasks to be done, and timelines. This is their weakest point.
Do you have any advice for potential customers?
Talk to them. I recommend Grinn because they’ve done good work and we’re happy with our end product.

Please describe your company and your position there.
I am the CTO of a comaony that provides tracking solutions for a wide range of sectors.
For what projects/services did your company hire Grinn?
We have been in a collaborative collaboration with Grinn to build state of the art and ahead of the competition hardware.
How did you select this vendor and what were the deciding factors?
We were connected with Grinn through refferal, we compared them with 2 others but in the end the open mindset and collaborative spirit made us decide for Grinn.
Describe the project in detail and walk through the stages of the project.
We are now in the proccess of building our second tracker with Grinn, which builds on the learnings of version 1. But in essence it is a redesing from a hardware perpsective. Grinn helped us out with brining new / emerging hardware components to the table. As well as a redesing (simplification) of the way the hardware components and the firmware works together. They also optimized the existing IP components we have created together in version 1
How many resources from the vendor's team worked with you, and what were their positions?
on average 3: A lead architect / PM, a hardware engineer, a Firmware engineer. For visionary debates Grinn adds specialists from the company to the debate as required / useful
Can you share any outcomes from the project that demonstrate progress or success?
The tracker we jointly build has generated massive traction (albeit not ready for the market yet). We are conducting trials with large cargo shippers as well as airlines. The fact that we managed to get a patent on our automated flight mode proves grinn knows what they are doing. The components for this to work were created by the grinn team.
How effective was the workflow between your team and theirs?
The workflow is very effective both firms believe communication is key especially when there is a physical distance between the companies. So we found a near perfect way to organize this.
What did you find most impressive or unique about this company?
We've run into brick walls many times but the team at Grinn always found ways to get the issues solved. They don't only make the hardware they trully put in the effort to understand the problem you are trying to solve and proactively think along side with you.
Are there any areas for improvement or something they could have done differently?
In our cooperation i can't really think of anything right now
Grinn's work has laid the foundation for the client's final product; their team has helped the client reach developmental milestones and meet technical specifications. The project is managed through GitHub, and the partners communicate through Slack and Google Meet. Grinn has great customer service.
