It is a complicated job, forming a dedicated team of software development experts who will completely meet your requirements and yield the optimal result. That's why we are here to manage the following steps:

We start by getting to know you as a business, analyzing your requirements and expectations from our outsourcing services, and discussing the plan for core development team formation. The final part of this step is approving the business arrangements and signing the contract.

We employ specific engineers to the core team, as well as providing technical and organizational support for the team launch. During this stage we implement the main processes for successful cooperation between you and the core team.

Your culture and working principles are incorporated into every aspect of the team's work. We improve and change processes for a more effective working practice, replacing or adding experts as required.

The management attention to team building, quality hires and personal touch is rare and I would recommend them in a heartbeat.

December 2016, we did a crowdsourced testing project with “Agilites”. At all times, the cooperation was at a very high level. The staff and support is very professional and great to work with. The planning phase as well as the proposed testing plan was really helpful in order to discuss all the details before starting, which saved us a lot of time during the project. As result, we got qualitative bugs reports with proper descriptions and helpful additional information (screenshots, video).
