Client testimonials

Vahid Walker

Sondre Rennan Nesset

They stayed within our budget and scope, and their deliverables met our expectations. Quality results to-date make re-engagement for further development likely. The project’s thorough discovery phase benefited Relevant Software’s successful execution.

Alexander Sagen

They delivered everything they said they would. I'm very happy with them. Relevant Software established a smooth process using agile methodology, while their responsiveness and personable approach contributed to the positive experience.

Paul Carse
CTO at Life Moments Ltd
United Kingdom

We needed a flexible, reliable partner that could turn our idea into reality, one who could quickly provide a team of experts that could design and build our product and infrastructure. Meeting with some of the Relevant team in London, we were impressed by their approach.

Christoph Renk
Founder & CEO of GommeHD.net

The reason we worked with Relevant Software is that they were very proactive about getting information from us. Other companies move slowly, but these guys move fast which is what we liked about them. Before we even kicked off the project, we would go into a lot of detail. That was quite impressive for us.

Ole Jørgen Næss
VP of Product and Engineering at Svenn

We had the challenge to find a trustworthy outsourcing company that we could rely on. Previous attempts ended badly and we needed to find a company that had the skills, good communication and was fair on price. We chose Relevant Software because we felt that they understood our business needs.

Balazs Wellisch
CEO at GameIQ

Relevant Software could adjust to our needs and provide the services that we needed in a way that they became part of our group very quickly. They were dedicated to the project and made sure every stage was made visible to the client.

Andriy Chemes
Co-founder at Radio Skovoroda

We were blown away by the team’s dedication and speed of work. We approached Relevant Software with the goal of creating one of the best online radio experiences in the world. I would say they have successfully achieved this goal.

Is SaaS applicable for enterprises?

Yes. As a business model and architecture, SaaS is applicable for businesses of any size and type of ownership.

How do I create a SaaS product with you?

Really simple. Just contact us, and we’ll discuss all the details.

Do I need to be tech-savvy to cooperate with you?

No, you don’t. Regardless of your tech experience, you can capitalize fully on outsourcing SaaS development to us. We’ll not just transform your requirements into technical specs for our developers. We will walk you through the entire process and answer your every question. Thus, you can focus on your core tasks while staying updated on the technical side of things.

Why is multi-tenant architecture the best for SaaS application development?

There’s no straightforward answer. Multi-tenancy is affordable and easy-to-maintain, making it a good starting point for B and C startups. On the contrary, many established businesses prefer single-tenant architecture for its performance, speed, scalability, better security, and extensive customization capabilities. If you are at a loss, let our experts provide you with SaaS development consulting to analyze your case and define the most suitable option for your needs.
