How We Conduct Business

  • Introduction

    We love meeting new people and learning about their venture before we shake hands and start building together.
    At this stage we expect to learn more about you and what you are looking to achieve and build. In return, we’ll share with you our vision, what we do, and how we do software development.

  • Business Call

    We focus on developing a more in-depth understanding of what you are building or want to build, how the product should be built, and your needs and requirements. By the end of the call, we expect to receive any documents that describe your business, vision, and any further information you have. At this point, if you have product specifications, documentation, and layouts, we would want to see them. If you don’t have these elements yet, this is when we could help you create them.

  • Analysis

    We assign a team of experts to analyze your product in terms of both technical and business requirements. During this step of the process, we determine the potential for your project. At this stage, if we feel that your idea may not be quite ready for development, or that there may not be a market for it, we will let you know. Above all else, we want to see our customers succeed, and we’re not afraid to tell you when we think a project should be shelved.

  • Initial Agreement & Proposal Development

    We present you with a project timeline and budget based on the information provided. The more we know about your venture, and the more accurate information we have, the more accurate our own estimations will be. In creating this estimate, we strive to account for the inevitability of unexpected delays and complications, so the margin of error is calculated for both the timing and pricing of the project.

  • Hiring Your Core Team

    Hiring the best core team to build your venture is not an easy task. We scout people who are excited to build your solution, rather than simply working for the money. We hire experts who have experience building solutions which are similar to your product. The hiring process takes up to 2 months.
    During the hiring process we present you with an overview of the experts that could potentially work alongside you to build your venture. The next step is an introduction call where you meet the expert(s) and get to know them, their abilities, and background.

  • Agreement Finalization and Signing

    We finalize the agreement and agree on the financial terms and move into signing the agreement to secure the future of the deal.

  • Solutioning and Scoping Work

    At this stage while the hiring process is on-going, we start developing scope of work and setting up milestones. At this point we also set up the dev environment and the communication channels between the client, the PM, and the team. Essentially, everything that is needed before the development work begins, in order to lay the foundation for a successful project and free flow of information.

  • Delivery

    We deliver the scope of work, detailing the typical software development life cycle, as well as defining the checkpoints during the development process allowing feedback to shape the growth of the project.
