Sublime Systems

Sublime Systems was founded in 2020 with the belief that cement manufacturing should be remade for the next millennium. Five years later, we have evolved from a project within an MIT lab into a nearly 100-person company, from gram-scale production to developing our first commercial factory. This past Friday, we at Sublime not only celebrated Pi Day, but also gathered to celebrate our company’s birthday! We always take our company’s birthday as an opportunity to reflect on our team’s efforts and the exciting road ahead. This past year alone, we’ve: ✅ Completed our first commercial projects with Sublime Cement® in WS Development’s beautiful Boston office building and promenade, allowing Seaport’s many daily visitors to experience some of the cleanest concrete ever poured. ✅ Secured a $75 million partnership with Holcim and CRH, two of the world’s largest cement producers to accelerate our path to full-scale production. ✅ Announced an MOU with Microsoft to speed deployment of our cement as a critical material for the clean construction need to support the AI boom. ✅ Saw bipartisan leaders accelerate transformative policy for enabling the innovative cements of the future to be used in public infrastructure, which represents half the cement market in the U.S. ✅ Announced our plans to scale our commercial production in Holyoke, MA, tore down a 100+-year-old smokestack from the site’s roots as a paper factory, and continue engineering and designing our future plant with the support of local, state, and federal partners. Each of these milestones brings us closer to our vision of ushering in the future of clean, efficient, cost-effective cement manufacturing. As we continue to transform manufacturing of the world's most essential building material, we are deeply grateful for the dedication of our employees, investors, partners, and supporters, who have all been crucial in our growth. Together, we will keep building! #KeepBuilding #SustainableBuilding #NextGenerationCement

Our team had a great time at the ARPA-E Energy Innovation Summit this week, which truly showcases the best of the best in American scientific innovation. We enjoyed sharing about our technology and progress in scaling next-generation, electrochemical cement manufacturing, as well as the opportunity to connect with so many other industrial innovators. #KeepBuilding #ARPAE #innovation

It’s exciting to see the magical material that is cement (a.k.a. the “rock glue of concrete”) get the recognition it deserves — especially from a prestigious architecture magazine like Domus. Concrete is an essential material in the architecture and construction industries and is used so widely that it often goes unnoticed. In Domus’ latest issue, our CEO and Co-Founder Dr. Leah Ellis explains why an innovative approach to cement manufacturing is crucial for the future. Huge thanks to Bjarke Ingels, BIG - Bjarke Ingels Group, and the Domus team for this incredible spotlight! #KeepBuilding #InnovativeManufacturing #NextGenerationCement

We’re all here for #SBMPitchDay 2!   Following a warm welcome with Juan Pablo San Agustín, we started the day with a panel discussion on the lessons working with large corporates. Thanks to our host Tulika Raj and our panel members, Apoorv Sinha, Hannah-Mei Andrews and Leah Ellis for their participation. Some key takeaways from the discussion include: ‘True innovation isn’t won by pitching ideas alone; it’s about forging strategic partnerships that help you execute and produce real-world outcomes.’ - Leah Ellis, Sublime Systems ‘Scaling innovation is a marathon, not a sprint – it demands the patience and persistence to overcome challenges and unlock breakthrough solutions.’ - Hannah-Mei Andrews, Climate Investment (CI).   Now, we’re looking forward to hearing from CHASM Advanced Materials, Inc., Neocrete, Mimicrete and Enzymatic about how they plan to reinvent the way our world is built.   Good luck to those presenting today!   #Accelerator #PanelDiscussion #ConTech

#EarthNight2025 is less than two months away! 🎇 We are incredibly proud to honor Dr. Yet-Ming Chiang, a clean energy pioneer, at this year’s event. Driven by a mission to develop green technologies, his accomplishments range from launching clean energy startups Sublime Systems and Form Energy to serving as the Kyocera Professor at MIT Department of Materials Science and Engineering (DMSE). Come celebrate his leadership with us on May 1 at Fenway Park: https://lnkd.in/g-AHWHcm - - - #CleanEnergy #ClimateTech #ClimateTechnology #CarbonFree #NetZero

We would like to congratulate the winners of our internal awards, the Atlas Award and the Athena Award, for February 2025! Here at Sublime, we believe it is essential to recognize employees who go above and beyond because it is their hard work and determination that has propelled us to where we are today. The winner of this month’s Atlas Award is our Pilot Team! This group displayed resilience in overcoming a collection of hurdles on the way to upgrading our pilot system. Thank you so much to Matt Pappacena, Scott Young, and Mark Farrier for your exceptional efforts, as well as Mathias Ferber for the nomination! For the Athena Award we wanted to recognize the Process R&D Team! This team’s wisdom led to new discoveries about our technology, which led to the utilization of the entirety of our starting feedstock. Congratulations to Mariya Layurova, Rita Silbernagel, Margaret Rzucidlo, Carlos Quintero Arias, and Natalie P. on the award, and thank you Michael Stern for bringing this accomplishment to light! Thank you all for your outstanding contributions! #KeepBuilding #InnovationInConstruction #SustainableBuilding

Congratulations to Anant Gupta for winning our Valentine's Day cement necklace giveaway! Fun fact: Anant has been following Sublime Systems since high school, when he read about us in an MIT Technology Review story. He's currently a chemical engineering student at Cornell University and is excited about the future of breakthrough clean industrial processes like Sublime's!

Thank you to everyone who joined us last week for our Future of Infrastructure event in Boston! 🚀 Jonson Berman kicked off the event with a thoughtful reflection on the evolving infrastructure landscape, highlighting both the challenges we face and the optimism fueled by emerging technologies. We went "Back to the Future" with a fireside chat led by Jit Kee Chin. Jay Tangney, and Dan Larche revisited their experiences with Boston’s Big Dig and explored how modern technology could have mitigated some of its biggest challenges. We then heard from an impressive lineup of startups – AirWorks, Exodigo, FLUIX AI, Kaya AI, Luminous, Noteworthy AI, Paces, and Sublime Systems – each redefining how we approach infrastructure development through cutting-edge solutions. The event concluded with two insightful panels: one delving into the future of grid management and renewable energy, and the other examining innovations in data center construction. Both sessions ignited discussions on the evolving landscape of energy and digital infrastructure, highlighting the pivotal role of technology in building a more resilient and sustainable future. 🎥 Missed the event?

❤️💎“Diamonds are forever,” they say, a symbol of enduring love.💎 ❤️ Yes, diamonds are nominally durable. But they’re combustible and thermodynamically unstable: imperceptibly and inevitably turning into graphite.  Cement, on the other hand, is inflammable, thermodynamically stable, and gets asymptotically stronger over time. What could be a better symbol for true love?    Sublime Cement®, rather than being forged under pressure in the bowels of the earth, is being created with precision technology. With the hope of building a better world — one in which people want to be, one in which we build with pride and shelter each other from the harshest elements.  While we aren’t in the business of selling cement jewelry (yet), we’ve found an incredible artist who is. We’re giving away a favorite piece from Shaham Hadas’s line to raise awareness for the lovable material that is cement. To enter the giveaway for this heart cement necklace, like this post and make sure you are following Sublime on LinkedIn, plus comment or reshare this post for a bonus entry in the drawing. We’ll pick the winner by next Friday 2/21 and will announce soon after! #CementisForever #StrongerOverTime #ValentinesDay #KeepBuilding
