Discovery stage is the most important
part of the project development

In our experience, the discovery stage of application development is often crucial for project success. That’s true whether you are developing a new product or onboarding an existing one.

Our team will study your project, gather key functional requirements, define the market fit, and analyze every option to find the technical approach that will work best for your product. By working with us to map out your entire product development cycle, you’ll be able to effectively plan project stages, perform initial estimates, and define critical points to be defined further.

Think of the discovery phase as your trail map for a hike through a dense forest. Without that map, you have a good chance of getting lost. To get where you want to go, you need that map.

We were impressed by Diffco’s approach to the development process and how they engineer new solutions. They look upfront, learn your product and strategy to develop more sophisticated and functional solutions.

Stas Tushinskiy,

We had the opportunity to work with Diffco on one of our iOS development projects. After working with Diffco, I can say without a shadow of a doubt that the team, their work and the experience that they brought to the project was truly exceptional. I would work with Diffco again in a heartbeat and highly recommend them for any mobile project at any stage of the development process!

Igor Gubernsky,

Foodrocket

As a startup we needed a team of professional mobile app developers that would step in as an extension to our team to cover mobile development. This is when we contacted Diffco. In our project we already had iOS developers. But we had some problems with Android engineers. As a result, we launched that right on time, got approved in Google Store from the first time, and the developed app is working very smoothly. We got very positive feedback from our clients, aligned the speed of developing both apps (for iOS and Android) and raised a round of investment funding.

Vitaly Alexandrov,

CEO

FlashGrid

The Diffco team studied FlashGrid’s product and marketing strategy to make sure all of our requirements were addressed. Together, we found the look and feel for the website that are suitable for a company working in the enterprise segment. The new website turned out very intuitive and easy to navigate. After deployment, website support and updates are maintained by Diffco. This is a very productive engagement model as we now have a competent team available to make changes on a short notice. All in all, great job Diffco.
