Platform.sh evolves into Upsun, the cloud application platform built for humans and robots

Formerly Platform.sh, Upsun builds on proven foundations of reliability, compliance, and sustainability while introducing new capabilities to power AI-assisted development and enterprise-scale modernization.

23 September 2025, San Francisco and Paris - Platform.sh, the trusted cloud application platform used by more than 6,000 enterprises and 16,000 developers worldwide, today announced its evolution into Upsun. This strategic evolution reflects the company's future-ready focus to assist enterprises in accelerating digital transformation with AI at the forefront.

“The transition from Platform.sh to Upsun symbolizes our significant evolution as a company. Our growth over the last decade required a brand that captures our commitment to global reach, exceptional service, and continuous innovation. As enterprises expand the use of AI in software development, Upsun will provide the AI support they need to increase productivity and deployment velocity, and help companies manage risk–all while ensuring application quality from development to production and beyond,” said Fred Plais, CEO and Co-Founder of Upsun (formerly Platform.sh)

Trusted foundations, expanded capabilities

For a decade, multicloud flexibility, built-in security, and compliance have been cornerstones of Platform.sh. Providing organizations with the ability to manage complexity,  optimize cost, maintain compliance, and ensure performance across regions and providers such as AWS, Azure, Google Cloud, IBM Cloud, and OVHcloud.

Platform.sh has set the standard for environmentally responsible cloud operations, and Upsun continues this commitment with its multicloud location-based approach and carbon intensity transparency. It also offers its users a greener-region incentive to deploy to low-carbon data regions. These trusted foundations that defined Platform.sh remain at the core as the company evolves into Upsun. 

Upsun is the company's strategic expansion into modern application lifecycle management, accelerating AI-assisted development and AI-augmented workflows. Giving enterprises the tools to keep pace with the rapid adoption of AI, unlocking new opportunities for innovation.

Full steam ahead on accelerating the software delivery lifecycle

As enterprises accelerate their adoption of AI, Upsun supports human developers, AI agents, and coding assistants. It provides a robust and intelligent environment for modern software development without the need for costly overhead and complicated infrastructure management:

• Multi-runtime compatibility: a single, consistent platform for Python, Node.js, Java, .NET, Go, PHP and more enables teams to choose the best language for each service, accelerating delivery and reducing operational overhead.
• Upsun streamlines day-to-day operations with GitOps workflows, Continuous Delivery by default, fully managed services, and built-in observability, cutting developer toil, and speeding incident response.
• Risk is contained with Isolated Preview Environments that mirror production, observability guardrails, automated backups and comprehensive access control, safely and securely enabling rapid innovation.
• Onboarding is accelerated by AI-generated Configuration supported by a comprehensive CLI and a VSCode extension. 
• Upsun’s MCP server and API give AI agents a secure, auditable way to invoke platform tools and run runbooks, and enables direct developer interaction from their preferred LLM-enabled IDE (Claude Code, Github Copilot, etc)

Upsun empowers teams to build and deploy AI-enabled and non-AI applications with confidence.

“The move to Upsun recognises how far we have come. Developers get speed, simplicity, and scalability. Enterprises get standardization, security, and sustainability. With our shared values, we’re building a company that’s not just future-ready, but future-defining. This brand evolution sets the stage for everything we are building next,” said Nigel Kersten, CPO at Upsun (formerly Platform.sh)

Reliability and continuity with momentum

With a refreshed look, Upsun continues the Platform.sh commitment to ensuring enterprise reliability, building customer trust, and striving towards ESG leadership. Customers can expect the same high level of service, now with enhanced capabilities designed for the next decade of digital transformation.

"As Upsun, we look forward to continuing our journey of growth and innovation, ensuring our clients can confidently navigate the complexities of modern digital transformation," said Fabien Potencier, CTO of Upsun (formerly Platform.sh).
