Have a question?

How much does it cost to hire a developer at Proxify?

When it comes to pricing, we believe in transparency. You always know how much you will pay. Our simplest pricing plan is flexible pricing where you pay between 28 and 35 euros / hour. That's it, no hidden costs and no startup fees. The price you pay between 28 and 35 euros / hour depends on the experience and seniority of the developer selected. If you know in advance that you will need someone part-time or full-time, we can offer you an even lower rate if you are able to commit to those hours. You can always switch between our pricing plans.

How does the risk-free trial period with a developer work?

It's simple, due to our thorough and best-in-class vetting process, we know that our developers are among the very best in their field. This is why we can offer you a risk-free trial for one week. You only pay if satisfied.

Can Proxify really present a suitable developer within 1 week?

Yes, in close to all cases we can present a developer within a week. There can be cases where a client might be searching for a developer with particular, additional skills or experience and then it can sometimes take longer to find the right candidate. If you feel that your case may be unique or particular in any way, contact us and we will do our best to tell you the most likely time frame for finding the perfect talent for your needs.

How does the vetting process work?

We pride ourselves on the fact that we have one of the industry's most comprehensive vetting processes. We receive thousands of applications from developers who apply to become a part of Proxify but only a fraction of those developers pass through our screening process: interviews, code, logic, personality and English tests - we told you it was comprehensive! Indeed, under 4% of those that apply become a part of Proxify and this enables us to guarantee that you will be presented with a senior, trusted developer who we know will be the perfect match for your company.

Stress-free hiring of tech expertise starts here

Coding is a universal language. That’s why Proxify searches far and wide for the best global talent within tech. We make it safe, secure and easy to hire developers and designers. And at a good price, of course.

In a short 15-minute call, we would like to:

  • Understand the type of talent your company needs
  • Discuss the most suitable engagement plan for you
  • Tell you exactly how Proxify works
