LeanCode

BACKGROUND

Please describe your company and your position there.

Activy Bike&Run Game - mobile app serving as a wellbeing tool for employers to organize fitness challenges for employees. The scientific gamification in cycling&running challenges helps people to build healthy habits and promote active lifestyle.

Corporates and startups use Activy Challenges in mobile app to drive engagement and promote health or CSR programs at their workplaces. Activy app was also used by city authorities to run city-wide bike transportation games as social campaigns.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire LeanCode?

Having a rough web prototype we started working with Leancode to build a mobile app which track sport activities and gamifies them to organize challenges for corporates, cities and free games for users.

The scope of the project also included web admin panel, game creator as well as web platform for end users. With this complexity we relies on Leancode not only with development but also ideation, UX, business model design, prioritizing features.

What were your goals for this project?

We run a B2B2C business model so the goal of the product is to serve both customers (employers, cities, brands) and also end users (cyclists, runners, etc.). Before building the product we already had clients like Google, Microsoft, Santander, DHL, DPD and many other well known brands.

This is why were particularly focused on the best-in-class solution with highest standard of quality. At the same time we need an extra usability to make the gamification method appealing for end users to achieve the positive impact on their health habits.

SOLUTION

How did you select this vendor?

We talked with many potential vendors but there were 2 factors that led us to select LeanCode:

1. experience of founders and PMs from building their own products and startups
2. unique experience with technologies to lower the cost of building MVP and early stages of products Most important we decided to run pre-development workshop with LeanCode which helps us to understand the quality, values and principles of the team. And that makes all the difference!

Describe the project in detail.

From 2018 since now we built 3 versions of the product:

1. MVP: server app and iOS and Android clients, web admin panel (.NET, Xamarin, Azure). All UI was also delivered by LeanCode to make the development process smooth and cheaper
2. Activy 2.0 - adding Machine Learning module to detect frauds and automatically detect and track bike rides without even pulling the phone out of the pocket
3. Activy 3.0 - rebuilding apps with completely new UX and lots of new features based on user feedback (React Native), lots of development on server side, building web platform for end user (React Native). We also implement Google Cloud Firestore database to record activities. UI was delivered externally this time

What was the team composition?

The size of the team changes over time as LeanCode is known with their great flexibility and understanding of clients. Since 2017 we run 3-5 months of development process with a team ranging from 1 to 8 developers (usually 4 people). We tested many models of building product and maintenance so we really do not need our internal development team so far.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

Since 2017 we've served over 400 customers (big employers) with names like Google, Microsoft, Santander, DPD, DHL, 3M, Robert Bosch, Hochland and many others.

The avg. rating of the app is 4.4 vs. 4.1 fo the pretty difficult category of health&fitness app. We have over 35 000 users across Poland, Germany and Netherlands.

The app wins the Imagine Cup Smart City 2017 competition organized by Microsoft, also with extra prize for design. Activy was also recognized as the best startup in Innovation 2018 competition in Poland and took part in Google Campus Acceleration program.

How effective was the workflow between your team and theirs?

At the beginning as a founder I was the part of the development team working as a full time Product Owner and Manager. At the next stages we included our in-house junior PO and backend developer.

It was experimental but works really well as guys from LeaCode are also very open to test new approaches. LeanCode taught us how to build great product effectively.

They introduced all the popular tools and frameworks to our team which had zero experience at the beginning. We learnt a lot from them and also got valuable technological inspirations. They are still very engaged in our business!

What did you find most impressive about this company?

If you decide to work with LeanCode you will experience a lot more than an usual relation between a client and a vendor:

1. they understand businesses, not only technology
2. they share their experience from building companies and products
3. they have empathy combined with responsibility And they are really lean - both for small and big clients. I experienced a long entrepreneurial journey with them.

Are there any areas for improvement?

From time to time they are too optimistic with booking time for you so be prepared to wait a few days more to start a project. I think it's because they really want to be flexible for you and other clients. If you want to design a simple website you'd better hire other folks as LeanCode should deliver a good piece of software rather than the trivial frontend.

BACKGROUND

Introduce your business and what you do there.

I’m the owner of Kędzia Farm, a company that does farming and breeding.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with LeanCode?

I was looking for a software house that would be able to solve a few problems that I had on my farm. I wanted to create a mobile application to solve the problems of everyday management problems for farmers.

SOLUTION

What was the scope of their involvement?

They developed my mobile app. The main key was to use it for barn management. The app was also aimed at helping solve the problems in animal welfare with a special focus on ventilation in every barn and farm.

What is the team composition?

I worked with the owner. They also assigned a project manager and about 10 people in total who worked on my application. It’s a three-part mobile application. In each part, there were 2-3 people doing the work.

How did you come to work with LeanCode?

I met with other software vendors, but the people were too close-minded. 

How much have you invested with them?

I spent about $25,000.

What is the status of this engagement?

We worked together from January 2018–December 2019.

RESULTS & FEEDBACK

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

Animal breeding is a difficult profession and they were very keen to help and understand. They had very good ideas for the application. I started testing the app on my farm. I’m now trying to scale it. I’m happy with the quality of their work. It was sometimes even better than I expected. I will have to work with them again because I can’t find anyone better.

How did LeanCode perform from a project management standpoint?

Communication was good. We met in person to go over the project before the development started. I went to their office and had a long meeting with them where we tried to write down everything. It was a very fruitful meeting. In every meeting, we were able to solve problems. 

They were always on time and the ideas they had to solve the different problems were very innovative.

What did you find most impressive about them?

My favorite part was the people and the way they were very involved in the project. They were very keen to understand what I’m doing and find the best way to solve it. They try to give me more opportunities to have a few more things in my application. They were very involved and very hardworking.

Are there any areas they could improve?

I’m really pleased with my application. I would only change some tiny things but nothing big.

Do you have any advice for potential customers?

I recommend using them because they’re very open to their clients. They have so much knowledge to solve problems for different professions.

It was very effective workflow. LeandCode demonstrated big flexibility skill specially working with such a big player as Shell. Teams were constantly adjusted according to the required scope and priorities.

I was impressed with the knowledge, the level of the commitment working with us, and how they went beyond the agreed level of support. Great communication skills of the owners. LeanCode helped Shell to shape and learn new agile ways of working with sprints, scrum, etc. They exposed us to new skills and competences.

Are there any areas for improvement?

As I am not the technical expert, I cannot identify the technical area for improvement. However, there are always ways to improve communication and collaboration.
