Our full range of services

As a leading software development company, we have offered quality services to our clients since 1994!

Gislen Software was founded in India in 1994 by Mikael Gislen, a Swedish computer professional and businessman, who saw the potential in combining European management and commercial expertise with the IT skills, productivity, and cost advantages of India. This approach helped us grow into a leading software development company. Today, we have a diverse team ready to meet the needs of demanding global clients.

We work closely with clients throughout the development process to ensure we meet the defined objectives. We use agile methodologies extensively and tailor our ISO 9001-based software development process and quality standards to each project.

Bridging cultures – Building quality

About us

A Learning Organisation

We constantly improve

We believe that curiosity and quality go together: We encourage engineers to explore new tools and approaches, but we only adopt what stands up in real projects. Every new idea is tested against maintainability, security, performance, and long-term support, so curiosity translates into dependable delivery rather than experiments in production.
A learning culture you can tap into: Gislen Software, a leading Software Development Company, has built a corporate learning culture where we freely share knowledge and continuously improve how we deliver.
Cross-cultural collaboration: We consciously train our staff to work and communicate successfully across cultures, so distributed teams stay aligned and productive.
Stability and continuity: We have very low attrition compared to what is expected in our industry, helping clients keep momentum and retain domain knowledge over time.
Depth of capability: Our team includes qualified IT engineers, architects, business analysts, and project managers—covering the full path from discovery to delivery.
Shared expertise, not siloed knowledge: Clients benefit from the accumulated learning and expertise of our entire team, not just the people assigned to one project.
Process and accountability: We combine agile ways of working with disciplined quality practices (including clear documentation, reviews, and structured handovers), so progress stays predictable and improvements become part of how we operate—not just good intentions.

Technology we use

Proven foundations: We build on long experience with platforms and languages such as .NET, Node.js, Python, C/C++, SQL Server, and established integration solutions.
Modern web and mobile delivery: We deliver using React, React Native, Flutter, and native iOS and Android development—choosing what best fits the product and the team.
Practical AI in delivery: We use today’s AI tools to support analysis, development, testing, and documentation—treated as assistants, backed by engineering judgement, reviews, and quality controls to keep output robust and maintainable.
Commercial cloud platforms: We build and run systems on the major public clouds our clients use, including Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform (GCP), designing for scalability, resilience, observability, and cost control.
On-prem, hybrid, and sovereign cloud: Where data residency, regulatory constraints, or sovereign-cloud requirements apply, we support deployments in controlled environments—often European Linux-based estates—using Docker and Kubernetes, alongside private cloud and on-prem infrastructure with strong security controls, auditing, and operational discipline.
Mixed estates and phased modernisation: Many organisations need older and newer systems to coexist for years. We design integration patterns and migration paths that reduce risk, keep services running, and allow modernisation to happen in sensible stages.

Blended outsourcing

Blended outsourcing model: We have pioneered a blended outsourcing (distributed development) model, combining local and offshore expertise into one seamless delivery team.
Systems integration: We connect ERP, CRM, finance, data platforms and partner APIs so information flows reliably end to end. We work with Azure Integration Services, TIBCO and IBM middleware, and support migration from BizTalk to Azure. We also build open-source and code-based integrations (API-first and event-driven), with monitoring and clear error handling
Clear ownership and collaboration: We collaborate with expert partners where it adds value, while keeping delivery coherent—roles, responsibilities, and decision paths stay unambiguous.
Discipline in engineering: Our teams follow proven software engineering practices and apply software quality assurance (SQA) throughout the delivery lifecycle.
Testing that matches the risk: We combine manual testing, test automation, and performance testing to ensure each solution is reliable and fit for purpose.
Quality controls that hold up over time: Regular regression testing and thorough code reviews help us maintain high code quality; careful source code handling supports integrity, maintainability, and long-term value.
Continuous improvement: We keep refining how we work so we can meet industry standards, lower avoidable costs, and deliver systems that remain easy to improve.

Legacy System – Roadblock or Business Opportunity?

Legacy systems often keep businesses running – but they can also quietly slow them down. This blog covers about how thoughtful approach to software modernisation can preserve their business processes while building a more flexible, future-ready digital foundation.

From Access to web – modern system for lift inspections

Hissbesiktningar made the transition from an ageing Access system to a modern web platform – and the result transformed their business. Smoother inspections, better data quality and a new iPad app with offline functionality made a huge difference from day one. Read more about how we helped Hissbesiktningar with their digital modernisation from MS Access to web and app.

European Association for Cardio Thoracic Surgery

EACTS was founded in the mid-1980s as an organisation devoted to the practice of a highly specialised and complex branch of surgery for its members across the globe. The association decided to ask Gislen Software to conceptualise, design and develop a bespoke event management and membership system that catered for its requirements and those of similar associations.
