Find product-market fit
Our development methodology is laser focused on solving the customer's pain points instead of burning through the backlog. This increases your chances of finding PMF and building a scalable business model.
Speed up time-to-market
After understanding your business vision, we identify core MVP functionality and come up with a product roadmap. Then, we assign a dedicated team with the required skills and experience to deliver on time.
Extend your runway
Working with an external development partner saves you time and money compared with assembling an in-house technology team. This allows you to do more with your existing budget, giving you more room for iterating your product and achieving growth.

How to turn your startup idea into a successful product?
You've experienced a certain problem and thought about a way to solve it – not only for yourself, but for someone else too. Or, you've identified a particular market with unhappy customers ready to use a new product. Potential customers you've spoken to are excited about your solution. What happens next?
Come up with a lean way to validate your assumptions
Before investing time and money into a dedicated development team, it's important to test your key assumptions about your users' needs, the market and technical constraints. Do people really experience this problem and if so, are they willing to pay for a solution? Create a demo video of a future product and an invite-only waitlist to see how many people sign up. Buy your potential customer a coffee and ask some questions about their current situation. Get creative and collect helpful insights that will shape your MVP.
Raise early investment
Approaching VCs before you launch an MVP and start getting paying customers is tricky. At this stage, your best bet is finding individual investors who believe in your vision and/or investing your own capital. Your early investors may even come from the list of your future customers, as those have firsthand understanding of the pain you are trying to solve.
Hire a tech partner
Whether you are a technical founder or not, you can still benefit from bringing an external tech partner once the idea has been validated. This way you can focus on making business decisions, interacting with investors and even selling your product. Hiring a tech partner as opposed to finding a co-founder can also be a wise decision if you want to retain as much equity as possible.
By choosing us as your tech partner, you can:
Design a streamlined customer journey based on your ideas and market intelligence
Create a clickable prototype to collect user feedback and communicate your vision
Build a minimum viable product that properly addresses the needs of your audience
Develop a solution within time and budget limitations
Ramp up your existing development team to achieve roadmap goals
Iterate on your solution to find PMF and quickly test your assumptions
Improve your technology to support the growth of your company

How we work
For creating user-centric and user-desired apps, we use our R2D Product Growth framework. The R2D Product Growth framework consists of a series of iterations that solve three key objectives for our clients:
The R2D Product Growth Framework is a roadmap of a project that we assemble from necessary 2-week cycles depending on the business needs. According to this framework, a high-level roadmap looks like this:
R2D Product Growth Framework
To create our proprietary framework, we integrated all development stages with their respective best practices.
The main idea of the framework is that during the development of the product, we constantly prioritize the tasks required to be solved ASAP and proceed to the respective cycle. This approach allows us to run two or more cycles in parallel. Our R2D framework is a practice-oriented approach that has been used to deliver more than 250 successful software development projects. Unlike Agile, for each cycle, our framework offers proven results-driven stages and methods, which were carefully evaluated and chosen over the span of 10 years across hundreds of development projects.

The framework allows you to reach the expected results, transform chaotic ideas and feedback from the market into specific features, and keep on continuously delivering values to users in a changing market.
Technologies for Successful Tech Startups
Building a scalable growth engine by choosing the right technology.

Working in tech, we know how hyped up developers can get about a new technology, programming language or a library. But choosing a technology stack for your startup is something that has significant business implications, so it's something to be done with a cool head. It's crucial to select a programming language that already has a large community of developers, instead of choosing a new kid on the block. In addition, one has to consider scalability and performance aspects. After all, there's multiple iterations involved in building a product.
Our proven set of tools and technologies ensure that the provided solution will not only solve your initial business challenge, but also fit your long-term goals
