Cesium Joins Bentley Systems

Today marks a momentous day as we announce that Cesium has joined Bentley Systems via acquisition. We are thrilled to be joining Bentley, a long-time partner in digital twins and authentic supporter of the open ecosystem.

Bentley Systems is a leading infrastructure engineering software company. Its iTwin Platform powers digital twin solutions that are used by engineering and construction firms and owner-operators to design, build, and operate infrastructure around the world.

Together with iTwin, Cesium’s open platform provides a complete platform for building digital twin experiences for the natural and built environment, with a strong commitment to open source, open standards, and open APIs.

The combination of Cesium and iTwin enables developers to seamlessly align 3D geospatial data with engineering, subsurface, IoT, reality, and enterprise data to create digital twins that scale from vast infrastructure networks to millimeter-accurate details of individual assets, viewed from land, sky, sea, space, and deep below the Earth’s surface.

Over the last 13 years, I have been frequently asked about the long-term vision for Cesium.  From potential colleagues who want to know if we are building to an IPO, to customers and partners who want me to look them in the eye and confirm that we are in it for the long game in terms of supporting an open ecosystem for developers.

My answer has remained consistent - we are taking a big swing at building the open platform that empowers developers to build experiences with 3D geospatial data. In our DNA, we are committed to open source, open standards, and open APIs as a foundation that the ecosystem can trust to build their experiences and businesses upon. Joining Bentley helps us accelerate this.

I am often over-credited with the Cesium vision; the truth is that we have built open source and engaged in the community in the most authentic way we know how - through GitHub; our community forum; open standards organizations; and interactions at meetups, conferences, and hackathons. It is the community that has crafted the Cesium vision and guided us from our roots in aerospace to 3D geospatial. In the past few years, you have shown us that 3D geospatial is the foundation for experiences using the natural and built environment, anything from digital twins of construction sites, to smart cities, to building a space station on the moon. Our vision is, frankly, the observation of your vision.

How Bentley Helps the Cesium Community

I’m so proud of our team. We have built an amazing business with Cesium. We have been consistently cash flow positive and grown by double digits every year since we spun out from Analytics Graphics, Inc. (“AGI”, now part of Ansys), five years ago. Perhaps we are a rare story, proving that doing the right thing for the ecosystem and the right thing for our colleagues, is also the right thing for business.

We’re fortunate; we have options. So why join Bentley? Because we believe that we can make the most progress in the shortest amount of time towards building the platform you need and deserve, more so than if we continued to run the company organically or raise outside capital.

Just like an acquiring company sees a path to accelerate their vision, we are joining Bentley to accelerate the Cesium community’s vision.

A Shared Commitment to the Open Ecosystem

We met Bentley in 2016. They discovered Cesium through the open source community and saw the potential of 3D Tiles and CesiumJS for massive photogrammetry models generated by ContextCapture (now iTwin Capture) and massive interior and exterior Infrastructure models such as skyscrapers, bridges, and highways from MicroStation. They saw the potential of Cesium in Infrastructure Engineering before we did, a classic story in our journey.

Bentley then funded key contributions to open source CesiumJS and the 3D Tiles specification and served as part of the team that brought 3D Tiles 1.0 through the OGC Community Standard process.

It turned out that Bentley were also neighbors, headquartered just 15 minutes from where we started Cesium. We have spent a ton of time together. They have supported us in providing gathering space for our quarterly Refactors, and even provided use of Ray Bentley’s personal office during Shehzan Mohammed’s first week with Cesium. 

The personal connection matters. We are kindred spirits with Bentley’s founders, and we have a deep belief in the authenticity of Bentley’s new generation of leadership including Nicholas Cumins, Bentley CEO, and Julien Moutte, Bentley CTO. We thank them for putting their utmost faith and commitment in us.

Since 2016, Bentley has built many things using Cesium, including Offshore Wind Farms Simulation and Digital Twins with Geospatial Context.

Where we really see the open ecosystem ethos of Cesium and Bentley come together is with Bentley’s iTwin platform. As Keith Bentley, Co-Founder and former CTO of Bentley, stated in our podcast conversation in November 2022, Cesium inspired Bentley to build an open platform for digital twins for infrastructure engineering in the same style of Cesium: open source, open standards, and open APIs.

By joining Bentley, Cesium becomes part of a growing public company that shares its values and commitment to open standards and interoperability. Cesium capabilities will now extend to an infrastructure ecosystem representing some of the world’s largest and most significant projects and assets.

When thinking from the macro view of outer space or viewing an entire country to the micro view of being inside a building or under the Earth’s surface, bringing iTwin services to the Cesium community gets us there, further and faster.

The Future of Cesium and Bentley

The powerful combination of the iTwin and Cesium platforms will be an inflection point for the Architecture, Engineering, Construction, and Operations (“AECO”) and 3D geospatial ecosystems. We look forward to offering additional value, capabilities, and long requested features to Cesium users. Similarly, the continued availability of Cesium runtimes like CesiumJS, Cesium for Unreal, Cesium for Unity, and Cesium for Omniverse, in addition to curated data, and broad adoption of 3D Tiles, will enable significant advancements.

At the core is open standards and interoperability. We see an opportunity to accelerate the 3D Tiles roadmap, increase interoperability in the ecosystem, and create new open standards for specifications such as Bentley’s Base Infrastructure Schema (BIS) to interoperate with 3D Tiles and the community.

Bentley also shares our belief that easier access to data is a key driver of success. As such, we will be investing more in global and regional curated data and commercial data partnerships to enable you to build rich digital twins.

Last but certainly not least, by integrating 3D Tiles into Bentley’s Open Application ecosystem, we ensure long term and sustained support for Cesium and 3D Tiles. Such an integration will allow users to create workflows that work for you across domains and analytics.

My Role as Chief Platform Officer at Bentley

In some acquisitions, the founder steps away or has a transition plan to step away soon thereafter. Make no mistake about it, Cesium and the community we support along with our open standards advocacy is my life’s work. At age 42 and with a myriad of options to advance this work, I see joining Bentley as the best accelerator.

Bentley has given me the opportunity to be Chief Platform Officer with the honor to lead Cesium and iTwin over time. I will stay hands-on and engaged with the open standards community as we increase our support. We will continue to earn it every day as we build for and with the community to support an open ecosystem for digital twins of the natural and built environment.

Your Role as the Cesium Community

Joining Bentley is Chapter 3 for Cesium. Chapter 1 was our start in aerospace at AGI. Chapter 2 was our spinout company for geospatial and finding our way into Infrastructure. In each chapter, the community guided us. We invested in open source and open standards; we authentically asked for feedback; we listened; and we acted. It’s because of you that we built Cesium for Unreal, Cesium for Unity, Cesium for Omniverse, collaborated with Esri on integrations, started the Cesium Ecosystem Grants program, and so much more.

Chapter 3 will be no different. We have a compelling vision to expand into infrastructure and subsurface, strengthening the open platform to serve the software developer community building digital twins for the natural and built environment. We need you to continue to guide us by letting us know what matters most to you. What do you need to be even more successful? What integrations between Cesium and Bentley would you like to see soon? What broader ecosystem integrations do you want to see? What developer resources and support do you need?

The Journey

I still remember making the first commit to what became CesiumJS in February 2011. I also remember when it rendered the first red triangle. To think that the vast majority of open source projects don’t receive much traction, let alone have a successful business form around them, and that most venture-backed technology startups don’t make it, it is with abundant gratitude for and to the credit of our team and the community that, through ups and downs, we found a rare win-win-win across the board. It comes with a successful path for Cesium to:

  • contribute a ton of open source and open standards to the community;
  • enable thousands of applications and businesses;
  • deliver value to our shareholders;
  • provide a value creation accelerator for Bentley;
  • continue doing what we do on a faster path

Thank you for your support of Cesium. We look forward to continued collaborations with you. Please celebrate with us, help spread the word, and share your thoughts and ideas with us on LinkedIn or the Cesium Community Forum.
