Feedback summary: 

Student feedback has been highly positive. Selleo excelled at the interpersonal parts of software design as well as the technical elements. They used daily communication to keep the project in check. Their company culture clearly nurtured an energetic and informal working environment.

The client submitted this review online.

BACKGROUND

Introduce your business and what you do there.

Neutopia is a SAAS learning platform. I am the project manager and CEO.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Selleo?

The main thing I was focused on was just making a better platform for learning from a teacher’s and student's point of view. I wanted it to be motivating and easy to use, and to encourage more curiosity from students. It needed to work in a more modern way than the other platforms I’ve seen.

SOLUTION

What was the scope of their involvement?

I approached them with the UX designs and the information architecture designs. From there, they did a quote on what would be required to implement everything on the designs. They provided backend and frontend services, and a little UX design help. Most of the UX was done, but they did some improvements and changes on the fly. The platform provides playlists for learning. Users can add content, similar to Pinterest, and make playlists and turn that into a course. Selleo used Ruby and Angular to build the platform. We started with two team members, and we got up to five.

How did you come to work with Selleo?

I did a web search for developers in Poland, and I found three companies, including Selleo. I chose them because I was really impressed with the first meeting we had. They seemed to be ethical, which I really liked. The quote they gave me was very professional. It was a line-item quote, whereas every other agency had just given me a price. Selleo also got back to me very quickly, and other companies took quite a long time. 

RESULTS & FEEDBACK

Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?

We’re still in the pilot phase inside schools, and the pilots have gone extremely well. The usage by students is very high. People love the platform. After students use it for several weeks, I get asked if I’m going to take them off the platform at the end of the course. They get concerned that they’ll be locked out. 

How did Selleo perform from a project management standpoint?

I think they’ve done a great job.  Before starting the project I had heard stories of some of the challenges of building software, but I’m happy to say the process of building the platform with my team at Selleo has been excellent and very enjoyable.The guys are like family to me. Even as a virtual team, I probably see them more than some of my friends here in Sydney.  I look forward to the standups and really enjoy my working relationship with all of the guys.

What did you find most impressive about Selleo?

What sets Selleo apart is the enthusiasm and care taken on the project beyond scope. We have a spirit on the team that’s definitely in the culture at Selleo, very similar to the type of culture I try to foster as a teacher. I look forward to our meetings, it’s always fun as well as productive.  The guys are really into the project and I know they really care about it’s success. I believe Selleo chooses very good people and have an excellent company culture.  I’m very happy to be working with a company that shares my values and that has made the whole experience work very well.

Are there any areas Selleo could improve?

I can’t think of anything.

BACKGROUND

We are a foundation which grew out of a web and mobile community, aiming to provide an interactive forum for IT people interested in the unique mixture of networking, knowledge-building, as well as practical and productive skills development. I’m the Vice Chairman of the Advisory Board.

As the host of one of the biggest admittance-free IT events in Europe, we were looking for a multi-platform cloud-based conference management application to mobilize and socialize the conference. 

OPPORTUNITY / CHALLENGE

We needed a dedicated event platform and cross-platform mobile solution to help a few hundred participants navigate through the agenda. The app needed to list multiple lectures and workshop, supply the attendees with information about presentations and speakers, and encourage participation and elicit feedback for improvements in the future. 

SOLUTION

Our event management platform consists of a custom Ruby on Rails web application, which we used to enter event data and gather and analyze statistics and/or feedback. The web CMS [content management system], which connected with the suite of mobile apps for Android, iOS, and Windows Phone, was fitted with analytical features to track and measure user behavior in the application, gather feedback, and keep the data updated in real time. Selleo was responsible for the development of the whole product, including the web CMS platform and mobile apps.

We were looking for a software development house which could deliver both web and mobile solution under one roof, assisting us with application architecture and design development. Selleo fit our requirements and also presented a portfolio of similar software solutions. We received not only high-quality developers but also domain knowledge regarding data analytics, feedback gathering, and mobile data collection.

We worked closely with Selleo’s team to create the project scope. Having an initial idea of how the platform should look like, we didn’t know much about software development processes. Selleo backed us with the Agile methodology and an understanding of how to transform our ideas into application functionalities. To be honest, we had no proper documentation, just some rough ideas of functionalities. Selleo split these concepts into user stories, and then we co-created the project backlog.

Selleo assigned a varying number of people to the project based on our needs. Most of the time, we had 2 developers. They were responsible for web and mobile. Our project went from February 2014 to March 2015. 

RESULTS & FEEDBACK

The solution supported more than 800 users on all mobile systems—iOS, Android, and Windows Phone. We received very positive feedback. The app had a 4.9 score on Google Play. Users were happy with its simple UI and offline mode.

Our idea of developing a web event management system with mobile apps was conceived during a service design workshop that Selleo conducted for us. The system was designed and developed in close collaboration between our organization and Selleo. We felt like they became a unique part of our foundation. They were very responsive and allowed us to overcome some process challenges. Timing was a crucial factor, but Selleo managed to deliver the solutions within our agreed schedule.

Since we had no previous experience in developing software projects, Selleo was a great partner to work with. They presented high-quality project management skills. At first, we thought that conducting software projects would be extremely hard, but with Selleo’s professional approach, the work was easy and even enjoyable.

We really appreciate the way they deliver service and their whole company attitude. They are friendly, open-minded, and focused on the client’s needs. We had a really a great experience with them.
