Getting to market quickly creates a significant strategic advantage, as does being able to respond to customer feedback and demand for new features. To help with this, we take an Agile approach which allows us to break your project down into sprints for speed and flexibility. If you need to beat a competitor with your release, we can focus an initial sprint around an MVP launch and extend afterwards.

Our development portfolio

Blue Fever

The Blue Fever app offers a refreshing change from the toxic atmosphere of social media. Designed as a space for self-care and community support, it gives teens a chance to relax, speak about their feelings anonymously, and connect with others in a friendly and secure setting. Blue Fever mainly focuses on female-identifying Gen Z users, but it welcomes and includes everyone, creating a friendly environment for all.

The app features a unique caring algorithm known as Blue, which recommends supportive, user-generated content tailored to each user’s emotional state. Supported by Amazon’s Alexa Fund, Bumble Fund, and Techstars, Blue Fever is committed to reducing online toxicity and fostering empathy by introducing a new category of platform: Emotional Media, not social media.

We’ve always aimed to help people become their best, most confident selves. With rising rates of anxiety, depression, and loneliness, especially among young women, we believe the right tools can make a difference. Our goal is to empower young women to take control of their identity and well-being.

DoveMed

Health is the cornerstone of our lives. Unfortunately, many medical rating sites and resources are influenced by commercial interests, making it difficult to find reliable healthcare information. DoveMed strives to be a trusted online resource, offering high-quality medical information to both healthcare seekers and providers on an easy-to-use platform accessible to anyone, anytime.

Despite the numerous challenges that emerged throughout the project, they’ve built an incredibly complex platform. The website is well-structured, stable, and able to accommodate 500,000 users each month. More than 1.2 million physicians are registered on the site, and traffic is increasing by 15% each month.

Get your project going in just 5 steps

  1. Is it a match?

    Discovery Workshop

    We start our product design by thoroughly understanding your specific needs and challenges. In a kickoff workshop, we collect key insights about your current situation, challenges, and future goals. This info is then boiled down to a clear grasp of the problem we're addressing.

    • We'll assess your business to pinpoint key areas for improvement and growth.

    • We'll identify key challenges and align on how our product can meet them.

    • We’ll establish a clear vision, making sure our product fits your long-term goals.

  2. What's the plan?

    Design and Specification

    At the beginning of a project, our team concentrates on building a strong base for development. This includes outlining the project's scope, goals, and main deliverables.

    During this initial planning stage, several key things happen:

    • Designers will create wireframes and mockups to visualize the user experience.

    • The PM and Technical Architect will document functional and technical requirements.

    • Developers can join later phases with a clear understanding of the solution details.

  3. Are we ready to build?

    Software Development & Testing

    The project is now moving into its development phase, having laid the groundwork. This stage is where the initial plans and specifications are brought to life.

    Developers will explore the current documentation, clear up any uncertainties, and start creating the software's features.

    • We’ll start working in 3-week sprints and hold regular demos to show our progress.

    • You'll have full access to project management tools.

    • We’ll conduct rigorous testing to make sure quality and functionality meet the requirements.

  4. Is everything set for launch?

    Beta Release

    At this point in the project, everyone should have a sense of confidence regarding what has been completed, and all parties should be able to focus on moving the application into its final phase.

    • We’ll conduct user testing in the Staging environment to gather feedback and identify areas for improvement.

    • Now, we’ll review user feedback and pinpoint any needed changes to the project.

  5. Ready for future challenges?

    Launch and Support

    After launch, we offer ongoing support, including uptime maintenance, performance monitoring, and infrastructure adjustments as your application scales.

    • You’ll get continuous goal-oriented development or maintenance.

    • You can use our expertise to make informed decisions regarding future product development.
