Engagement models

Decide which model best suits your project


If I hire developers in Relevant, do they work only for me?

Yes, the hiring app development team will only work on your project without being distracted by other things. Even if you hire a team of full-stack developers, they will only work for your business project.

Will I get reports from the developers on time?

Yes, you will get daily, weekly, or monthly reports of the work done by the developers. As a top full-stack development company, we prefer 100% transparency.

How does it cost me to hire full-stack developers?

A true full-stack developer is rare, and the value is enormous, as an engineer can do the work of two or three people. So there is nothing extraordinary in a higher salary. The best way to find out more about fees is to contact our full-stack engineers.

What project management tools do you use?

We use Jira to efficiently delegate tasks, manage project costs and risks, and share documents in real-time.

What types of companies do you work with?

Since 2014, we've been developing web solutions for small startups and giant corporations in every field imaginable. From idea validation to execution, our full-stack developers for hire will take care of it all for scalable, feature-rich mobile, web, or desktop apps.
