Our full range of services

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. He saw the value of combining European management and commercial experience with India’s strong IT skills, productivity, and cost advantages. That idea helped us grow into a leading software development company. Today, we have a diverse team serving demanding clients around the world.

We work closely with our clients throughout the development process to make sure we meet the agreed objectives. We use agile methods extensively and adapt our ISO 9001 and ISO 14001 certified processes to suit each project. We are also Microsoft partners and work in line with GDPR requirements.

Bridging cultures – Building quality

About us

A Learning Organisation

We constantly improve

  • We believe curiosity and quality belong together: We encourage engineers to explore new tools and approaches, but we only adopt what proves its worth in real projects. Every new idea is tested for maintainability, security, performance, and long-term support, so curiosity leads to dependable delivery rather than experiments in production.
  • A learning culture you can benefit from: Gislen Software, a leading Software Development Company, has built a culture where knowledge is shared openly and the way we deliver keeps improving.
  • Cross-cultural collaboration: We actively train our staff to work and communicate well across cultures, so distributed teams stay aligned and productive.
  • Stability and continuity: Our attrition is low compared with what is common in our industry, helping clients keep momentum and retain valuable 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 combined learning and experience of our whole team, not only 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 improvement becomes part of how we work.

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 with React, React Native, Flutter, and native iOS and Android development, choosing what best suits the product and the team.
  • Practical AI in delivery: We use today’s AI tools to support analysis, development, testing, and documentation. They are treated as assistants and backed by engineering judgement, reviews, and quality controls to keep the output robust and maintainable.
  • Commercial cloud platforms: We build and run systems on the main public clouds our clients use, including Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform (GCP), with a focus on 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 model, or distributed development, combining local and offshore expertise into one seamless delivery team.
  • Systems integration: We connect ERP, CRM, finance systems, data platforms, and partner APIs so information flows reliably from 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, including API-first and event-driven solutions, with monitoring and clear error handling.
  • Clear ownership and collaboration: We work with expert partners where it adds value, while keeping delivery coherent so roles, responsibilities, and decision paths remain clear.
  • Discipline in engineering: Our teams follow proven software engineering practices and apply software quality assurance throughout the delivery lifecycle.
  • Testing that matches the risk: We combine manual testing, test automation, and performance testing to make sure 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, reduce avoidable costs, and deliver systems that remain easy to improve.

Long-term client relationships

Our strong commitment to both clients and employees sets us apart. We have built long-term relationships with our clients and have attrition rates that are among the lowest in our industry. We also aim to be a responsible corporate citizen, with a clear focus on business ethics, reducing our environmental footprint, and supporting people in need through Little Lambs School and other charities.

From listening to leading: My journey into requirements analysis

Posted on | by Vanitha Venugopal | Leave a Comment on From listening to leading: My journey into requirements analysis

Requirement analysis is often mistaken for documentation work. In reality, it is strategic thinking in action. After 25 years of working closely with stakeholders, I’ve learned that the real craft lies not in writing what is said – but in uncovering what is meant, what is missing, and what could go wrong if left unexamined.
