+
+Giant Swarm's mission is to empower our customers to build their own cloud-native [developer platform](https://tag-app-delivery.cncf.io/whitepapers/platforms/#what-is-a-platform). When development organizations and departments grow and their environments expand, they often face exponentially growing complexity in managing the lifecycle and operations of their application and services. Soon this gets overwhelming; to be fair, it's not our customers' core business. We believe that having a flexible, [unified cloud-native developer platform](https://tag-app-delivery.cncf.io/whitepapers/platforms/#why-platforms) plays a crucial role in growing your development organization efficiently. The platform not only helps to take [the toil](https://sre.google/sre-book/eliminating-toil/) out of the development teams to have less cognitive load but also enables capabilities to manage security and governance more centrally.
+
+Most of the developers want to deploy an app into production without having to worry too much about security or compliance, while maintaining control over deployment and monitoring options of their workloads. Our goal is to help the engineers who build and maintain the platform meet developers' expectations, without compromising their organizations' security posture.
+
+Giant Swarm addresses this challenge by providing a flexible base platform. The platform enables technology departments to ensure governance and control over development processes and operations, while providing developers a smooth development cycle.
+
+## Our platform, your platform
+
+You may be wondering: How does Giant Swarm achieve flexibility and standardization at the same time? Giant Swarm doesn't offer a one-size-fits-all platform which, in the most optimistic scenario, covers 80% of use cases while ignoring the rest of your business. Instead, we leverage cloud-native ecosystem to provide our customers with a set of features that helps platform teams to build a developer platform that fits the company's constraints, processes, and unique requirements. We believe that there is no universal internal developer platform that can cover all needs, especially in the enterprise world. For this reason we design our solutions to be modular and customizable.
+
+Our approach gives you the ability to define team-specific policies, flexible application delivery processes, or different traffic routing setups, just to name a few of the options. We help you create templates tailored to your team's needs while ensuring excellent visibility and control over their activities.
+
+## Working with our customers
+
+We offer a product that lets you start easy with a production-ready platform. Our team will work with your engineers every day, to build something that's tailor made to meet the challenges of your business head on. There is a common baseline that your security and governance team can trust on. Your specific requirements will be discussed and configured in collaboration with our subject matter experts. Good communication and support is key and this is exactly what we're good at. [Our customers endorse the collaborative effort to create a cloud-native developer platform](https://www.giantswarm.io/customers) together.
+
+At Giant Swarm, we take full responsibility for keeping the platform components healthy. We operate and monitor them on a continual basis and offer you upgrades and support. Even in cases where **your** application doesn't work as expected, we'll assist you to the best of our considerable abilities, until they do.
