I am Vitaly Kirkpatrick, CEO and Founder of CloviTek Inc, the wireless device manufacturing company that builds wireless audio transmitters for streaming audio from TVs over WiFi to mobile devices. I am repsonsible for overseeing the operations, sales and management.

Our team had built a hardware device that is capable of streaming audio. We had Engineers who were able to do feasibility testing to make sure that this is something that would be possible to do. However, our Engineers did not know much about mobile app development. We had to look for outside developers to help with the project. We had the challenge to identify the best developers for this technical project out of multiple companies that could offer Linux software development and mobile app development for iOS and Android mobile devices.

We wanted the app to be able to receive an audio signal from a TV and decode it in the mobile device so people could use their headphones to hear any TV out of multiple TVs available within one network area. With this solution, our goal was to test the market need for the product so we could go into full production and sales.

We worked with a couple of software development teams before. Unfortunately, they under-delivered and their product was not ready for release and sales due to poor design. However, the Diffco team was able to present the solution that had not just functional capabilities we were looking for, but also a modern look and a friendly user interface. It was clear to us, that Diffco team was capable of solving not only technical problems with audio streaming over WiFi, but also user's usability problems which were presented to us in the first design phase.

Once we selected Diffco to be our developer, we started the initial design phase. They were very quick in providing their deliveries for each phase of the development. After consulting with us and presenting their UI designs for the mobile app, we moved forward with the mockups development to test the functionality. The app mockups were delivered specifically for iOS and Android platforms within their native frameworks. Those mockups included the company's branding (colors, logos, images, etc.) to match our website, which Diffco developed and built for us as well.

From the beginning, I was speaking with the project manager who was very knowledgeable and understood the requirements which he delivered to his team. However, as the development of the project progressed, the team involved the Linux developer and the mobile developer to our remote meetings. Sometimes we needed to talk to their Engineer as well, which they provided to us for solving more challenging problems.

After working on the product and mobile app for a year, we had our first prototype developed. We've demonstrated it at various shows and received multiple innovation awards for design, functionality, and usability of the product. When we were able to go online, Diffco team developed our website based on the Shopify platform. We started seeing the sales of the product. However, we could not ship the product yet. Only two years later, with the help of the Diffco team in collaboration with CloviTek's Engineers, we started shipping our first orders to our customers. There were a few issues with the product and the app, which were addressed by Diffco in a timely manner.

The Diffco's project manager was located in the U.S., however, their development team was located offshore. The project manager was able to address all of our questions with our management quickly without the need to involve their offshore team to weekly calls. If there were more challenging questions to be addressed by their offshore team, we had in-house team members who spoke their language and were successful communicating issues with the app. A lot of the challenging technical issues with the mobile app were addressed successfully by showing via video recordings or conferences rather than telling about specific issues.

I was impressed by their technical knowledge skills their team had. They also know a lot about user experiences. The mobile app had an excellent UI design and functionality. Their biggest strength is they address issues quickly and communicate the outcomes to our team, resolving them if needed.

Some of the ideas during the process could have been explored and considered. Because of their own belief that they know the mobile app development best and that they have the technical expertise to solve challenging problems, some of the suggestions were dismissed and never pursued. They are an amazing team and I am retaining them for other projects. But, maybe having an open mind to suggestions could help them in a long time dealing with other customers. Delivering something out of extraordinary and learning something new outside of their comfort zone, would help them develop the skills that maybe other customers would need for other projects.

Reliable team with strong technical expertise

I'm the CEO of Devmind, the software development consultancy and software integration company. Diffco developed a back-end software for a digital content distribution platform created for our client, one of the major European airline companies. We needed to develop a reliable, autonomous, easy to integrate and maintain solution, that would work on remote infrastructure and perform all operations with deploying digital content on airplanes during their maintenance in airports. The project consisted of multiple subsystems developed by different teams. Diffco had excellent processes and standards in place, which made work with them easy and comfortable. They also have excellent technical expertise, which gave me the confidence to rely on them when choosing the right technologies and approaches. Together with Diffco, we successfully launched the first version of the full platform in 5 months and performed an integration in one of the client's locations. After this, the platform was successfully deployed to other airports and continue to update and maintain.

What is it about the company that you appreciate the most?

We met Diffco while working with one of our enterprise clients. We liked their approach, expertise, and quality of their work.

Many years of successful partnership

"I'm the CEO of Questroom - an immersive escape room and entertainment company based in Los Angeles. We hired Diffco to develop a website and a custom ERP platform that would include a booking system, customer feedback aggregation, business process automation, and statistical analysis.


We needed an exciting and memorable website with an attractive and emotional design, which would express the client's experience in our quest rooms. We also needed a custom ERP platform that would perform all our business processes, from the booking interface for users to order and room management system with statistics and business metrics monitoring.

The first version of the platform was successfully released within 3 months and was integrated into our business processes. This helped us optimize our internal business operations processes, increase our business activity, and acquire more clients.

I was impressed by how good the development and communication processes were organized. They replied very fast to all questions and requests. The solutions they developed work very well and are exactly what we were looking for."

Executive Interview
Vadim Peskov
Vadim Peskov
CEO & Co-Founder, Diffco
Please introduce your company and your role within the company.
I am Vadim Peskov, CEO of Diffco US. Our company develops stunning websites and addictive mobile applications for our clients. At Diffco US we turn mobile app and website ideas you dream up into great looking products utilizing years of experience and industry leading technologies. Whether you are a start-up ready to move forward from the whiteboard stage or an enterprise in the middle of a project that needs expert help, we will become your extended team that moves quickly to deliver the optimal solutions. Our services include web and mobile design, iOS and Android development, software development, MVP for start-ups and product consulting, as well as technical support. With offices located in the USA and Europe we service clients worldwide and deliver outstanding results, meeting even the most extreme deadlines.
Mention the objectives or the parameters critical in determining the time frame of developing a mobile application?
It depends on what stage you are right now. An idea, a sketch, a detailed technical task with
mock-ups of UI or even completed design of all screens. We work with different clients on every stage of readiness. Also it depends on the amount of work you need for prototyping, designing, coding. Besides, complexity of the application, amount of functions, and integration with a variety of APIs have a direct impact on the time frame.
How much effort in terms of time goes into developing the front end and back end of a mobile application?
Of course it depends on complexity of the application; in general, an average business app development takes 2-3 months to launch. If it requires more time, it means that too many functions have been included into the first version or MVP, so we offer our client to split the launch on stages and move some functions on to the next version.
What is your company’s business model?
We have in-house team, because it provides us with trusted and high quality professionals, as a result, we can rapidly plug into every project.
How is your business model beneficial, from a value addition perspective, to your clients as compared to other companies' models?
We do not only develop applications, we also help the start-ups with the business strategy of the product and we have local expertise in the US market. So we are not just about app development, we are about maximal benefits for our clients.
What are the key parameters to be considered before selecting the right platform for a mobile application?
First, we identify the target audience for the app, how people will use our app, where and in what circumstances. In addi7on to that we specify our client’s goals and plans, understand why we make this applica7on, only after that the platform can be chosen.
Which platform do you suggest your clients to begin with when they approach you with an idea (Android or iOS) and why?
It depends on the app, but in general for US market we recommend to start with iOS, because of its popularity, limited amount of mobile models and opportunity of monetization.
Android or iOS, Native or Hybrid — which platform is best to use to build your app? What are your recommendations?
If you have very limited time to launch and you definitely have to start with both platforms, you are forced to use cross platform solutions. In other cases, we recommend first to develop one native app and then work on another platform. Native app usually works better and gives the users satisfactory experience, which is very important to present your business idea. In the long run, we generally recommend moving on the native app, so it’s a good investment of time to start with the native app.
What are the key factors that you consider before deciding the cost of a mobile application?
It’s simple. We compose a detailed feature list of an application and estimate every item in hours. So we get a detailed total estimate on of the whole app.
What kind of payment structure do you follow to bill your clients?
It depends on the project and the negotiations with the client. Usually we try to meet the client’s requests on the payment structure.
Do you take in projects which meet your basic budget requirement? If yes, what is the minimum requirement? If no, on what minimum budget you have worked for?
It varies from project to project, however we recommend the budget of $15k for MVP.
What was the cost bracket of mobile app projects your organization did in 2015?
The cost of projects that we did in 2015 varied from $10k to $100k+.
