The Saritasa Difference

Why choose Saritasa as your FinTech development company?

For businesses to make the most of technology, they require an expert's calm and knowing hand. A committed partnership to illuminate the most efficient and beneficial path to success. That’s where Saritasa comes in.

mutual success

We Believe in Mutual Success

We care about successful customers, fulfilled employees, and useful solutions. Everything we do is intended to find the right balance of outcomes for the common benefit of all.

we solve problems

We Solve Problems

We are a team of driven experts, from developers to designers to engineers and beyond. We are passionately committed to wrestling with the most complex business problems and applying technology systematically to solve them.

partnerships over projects

We Value Partnerships Over Projects

We don’t take a transactional approach to our engagements. Rather, we foster personalized relationships built on trust and the perpetual delivery of benefits over time.


We Build It, You Own It.

It’s that simple. Once we finish development, we pass over the complete source code so that your project is yours – no fees or strings attached. Whether you want to continue working with us for maintenance and updates or take the project internally is up to you.

trust is earned

We Believe Trust is Earned

Our company is built on long-term partnerships, which means that we want to earn your trust and keep it. We do this through our commitment to absolute transparency, accountability, and reliability.


Our custom software development Process

Whether you’re new to custom development or a seasoned veteran, we’re committed to providing transparent, honest communication every step of the way.


We start by getting an understanding of your vision. That includes everything from your technical requirements to the needs driving this initiative. The more we know, the better we can develop a bespoke plan that will not just meet, but exceed your expectations.

Consultation & product planning

Once we understand your vision, we draw from our decades of experience to strategize the optimal approach to address your specific needs. This could include consulting on technologies, value engineering, an emphasis on lean development, and/or designing a product roadmap.

Wireframing & design

We go through a highly collaborative design phase before we write a single line of code. You’ll work with our expert UI/UX designers to create beautiful, intuitive wireframes and visual designs following our heuristic design principles.


This is where the vision becomes reality. Our expert developers consider everything from technical architecture to infrastructure setup to coding. Quality drives every aspect of this phase, from detailed documentation and code comments to a focus on security, and an emphasis on scalability and code lifespan.

Quality assurance

Once we’re “done” with development (software is living, so code can never truly be done), we undergo rigorous testing processes by dedicated QA personnel. This may include test cases, automated testing, penetration testing, and more.

Product deployment

After design, development, and testing, all that’s left is to launch! Our DevOps team uses Continuous Integration / Continuous Deployment (CI/CD) practices and automated deployments to ensure a smooth launch.

Maintenance & ongoing development

We want to be your technology partner. While we’re happy to hand off the fully documented code to you after the completion of the project, we’d love to be your partner for future releases, enhancements, and fixes. We have multiple levels of support and maintenance to keep your system running at optimal performance for years to come.

We are Builders of Better FinTech

We envision a world where FinTech is faster, smarter, and simpler through the strategic implementation of modern, innovative technologies.
