BACKGROUND

Introduce your business and what you do there.

I’m the CEO of Njuškalo, one of the top Croatian classified ad sites. Our site has different categories, such as automobile, real estate, miscellaneous goods, tourism, and more. Our company has around 90 employees, and we also have a sister technology company with around 50 employees.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Velebit AI?

We needed an experienced AI partner who was able to develop and keep accountability for large-scale and high-availability AI systems. We only had a small internal data science team, and they were focused on our current AI models and on developing new ones.

SOLUTION

What was the scope of their involvement?

Velebit AI has developed our whole data engineering infrastructure and deployed the AI models needed on a large scale for our classified ads business. For this project, they’ve been providing on-site and off-site services. Now, they’re in charge of maintaining the three AI services they’ve developed for us.

The three services that Velebit AI has deployed for us are our Recommender Classified Ads system, our Automatic Ads Categorization system, which is an AI system based on images and texts, and a real-time camera-based object detection system. They’ve also developed the entire engineering infrastructure behind those models to deploy them on a large scale. In addition to AI development services, Velebit AI has provided us with consulting services, supporting our internal team in developing new AI models.

How much have you invested in them?

We’ve spent roughly €100,000 (approximately $10,000 USD).

What is the status of this engagement?

We started working with them in May 2021, and our engagement is ongoing. They will keep working with us this year (2022) and next year (2023).

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

The systems that Velebit AI provides us with are used daily by millions of users through our app and website, so our entire platform is heavily loaded constantly. For example, we have about 4–5 million users every day across Croatia, Slovenia, and Austria, which is an outstanding number.

How did Velebit AI perform from a project management standpoint?

I’m satisfied with how well Velebit AI performs from budget and deadline management perspectives. They’re always on time, and whenever we’ve had delays, those are usually related to our internal support team. Overall, I’m really satisfied with how well they’ve delivered their work.

We have several communication channels. For regular communication, we use email and Slack. Additionally, we have biweekly meetings to go over project statuses and next-week plans, which are very important to me.

What did you find most impressive about them?

Velebit AI’s accuracy is impressive; they deliver what they promise. Additionally, they’re very collaborative, and they understand our needs very well. They’re open to our ideas and also offer their own ideas on how to offer a better service and have a smoother collaboration. Velebit AI’s team also has vast AI knowledge, and they’ve managed to present it to us in a very simple form. They’re always thinking ahead and proposing the best solutions to our challenges.

Are there any areas they could improve?

No, not really. It would be great if their service were less expensive, but we’re paying for the quality of their work, and we’re getting a good value out of it.

Do you have any advice for potential customers?

Be clear with what you want to achieve and let them propose the best solution for that. Additionally, allow them to step into your shoes and give them enough information about your company so that they can build specific use cases for your customers.

BACKGROUND

Introduce your business and what you do there.

I work at the Department of Informatics and Digital Technologies at the University of Rijeka. My roles are full-time professor and leader of the Laboratory for Semantic Technologies.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Velebit AI?

We hired Velebit AI to implement language and classification models within one of our projects, which involved a multi-layer framework for the information spreading characterization on social media during the COVID-19 pandemic. Our project was funded by the National Science Foundation, which provided money for outsourcing tasks like implementing models. Since this was during the COVID-19 pandemic, we were focusing on analyzing texts posted in the language of online media.

SOLUTION

What was the scope of their involvement?

Velebit AI provided NLP model implementation for us. First, my team collected and analyzed the data. Then, we involved Velebit AI in a few activities within the project. We had some models that had previously been trained for Croatian and other languages, and the team performed additional training and fine-tuning. 

In total, they trained two language models. For the first, they fine-tuned it and trained it on a large amount of data on COVID-19. The other model was already screened for languages like Greek, Bosnian, and Serbian. Velebit AI also fine-tuned this model for the COVID-19 text-domain.

For the second part of their involvement, they helped us with model classifiers. They implemented sentiment classifiers to help us analyze tweets in the Croatian language. The Velebit AI team also implemented models for retweet predictions, which would predict how many times a post would be retweeted.

What is the team composition?

We worked with two people from Velebit AI, including their main data scientist and another employee. Additionally, we were in contact with Davor (CEO)

How did you come to work with Velebit AI?

A scientist gave a presentation at the university, and he was great. I asked him if he could get involved in our project, but he was already very busy. However, he suggested we try Velebit AI, so we found them through a recommendation.

How much have you invested with them?

We spent just over €10,000 (approximately $10,000 USD). 

What is the status of this engagement?

We started working together in July 2020, and they were involved during two different periods. They finished the first part in July 2021 and the second part in December 2021.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement? 

Velebit AI was great. Our goal was to analyze some data and see if the models worked. According to our metrics, which involve results, published papers, and presentations, they were very successful and did their job as we planned. We were able to use the models in our scientific research to analyze texts in Croatian. We analyzed tweet sentiments and topics in more than 200,000 tweets. 

So far, we’ve published two scientific papers with our results and are preparing a third. The models are also available for further use, as the funding from the Croatian Science Foundation indicated. We also presented our findings to the Croatian Ministry of Interior Defence. 

How did Velebit AI perform from a project management standpoint?

They delivered on time. We communicated online due to the COVID-19 pandemic, using Google Meet and email. We also used phone calls, and it was easy to communicate with them. Since they were very responsive via email, we didn’t need to use any special project management tools. During our meetings, I would explain what we wanted, and they provided suggestions to improve the work.

What did you find most impressive about them?

I was impressed by how enthusiastic Velebit AI was about data science. They read scientific papers because they were so eager to learn. The team proposed some scientific approaches to us. Overall, we had a great collaboration. 

Are there any areas they could improve?

I don’t have any suggestions for improvement. 

Do you have any advice for potential customers?

I’d recommend them for any advanced task related to NLP, deep learning, and similar data science models and AI in general. For a successful engagement, I advise having great communication with them. In our partnership, I explained their tasks and what I needed from them. They were enthusiastic about this research and appreciated the problem because it was something special related to science.
