Energy Isn’t the Only
Renewable Resource

Help us make advanced, sustainably-sourced, zero-carbon infrastructure the worldwide data center standard. Experience the benefits.


Sesame gives you more for every IT dollar, bringing you the same technology as the world’s largest cloud service providers at significant cost savings and up to a 50% TCO advantage over traditional OEMs.


Get the latest tech, built on open compute principles and put to the test under the most demanding conditions. Sesame systems deliver superior performance, reliability, and efficiency. Plus we own our closed loop circular supply chains, giving you the ready supply you need to scale on demand.


The greatest way to reduce carbon impact is to not produce it in the first place. With Sesame, it starts with a commitment to carbon-zero manufacturing: designing eWaste and CO2 out of new IT hardware systems by sourcing high-end raw materials that are already in the economy vs. pulling from the ground or firing up factories.

The case for circularity

Data center growth has played a significant role in our current global climate crisis. At the root are decades of new hardware manufacturing and disposal patterns that generate massive amounts of eWaste and CO2. With these high stakes, decarbonizing the infrastructure that’s powering cloud computing, AI, 5G, IoT, and more will take more than green energy and carbon offsets.
