Yes. SixSq manages two SaaS SlipStream instances:
Nuvla SaaS: This is a general purpose commercial service that includes growing number of cloud providers. It's a great way to try out SlipStream as the service is free of charge; you just pay for the cloud services you consume with your provider.
- Helix Nebula Marketplace (HNX): HNX is the science broker providing fast access to federated cloud resources in Europe for large and small research institutes. It can be used as well as for commercial research.
