+## History
+
+- They started with upstream kubernetes - the hard way
+- Env grew to over 200 prod apps
+- Pains: Single Cluster, single point of failure and complexity
+- What worked: Dev adoption and autonomy, no vendor
+
+## Challenges
+
+> Based on stakeholder expectations
+
+- One tenant per cluster -> Over 1000 Clusters
+- Release management
+- Small team (3 Engineers)
+
+## Guiding principles
+
+- Platform as a product
+- Stability: trust
+- Standardization -> Scalability and inter team collab
+- Day 2 support
+- Dogfooding
+
+## Tenancy
+
+- One cluster per product
+- Own CLI, devs like cli
+- Custom operator and crds
+
+## Stack
+
+- Keopsctl? Pretty much their own cluster operator
+- A Simple Cluster CRD
+
+## Migration
+
+1. Build trust in platform
+2. Support with docs, oboarding, q&a
+3. Co-create with devs while keeping an eye on day2 -> Feature-Flag based rollout
