Congratulations to Coleman Horsley, PE for winning the drawing, and thanks to everyone for playing along with our joke! While cement accessories and apparel aren't exactly in our roadmap, we are as committed as ever to advancing clean, durable, aesthetically pleasing Sublime Cement® in our built environment. #KeepBuilding

ANNOUNCING MAJOR COMPANY PIVOT: Cement is essential, so we are working hard to make sure you have Sublime Cement®  for *your* closet essentials!     That’s right, Sublime is expanding into apparel! Entering the $400 billion cement industry, responsible for 8% of global CO2 emissions, with our clean, high-performance, aesthetically pleasing Sublime Cement® wasn't enough for us. We're ready to take on the ~$2 trillion global fashion industry, which is responsible for ~4% of global CO2 emissions! To celebrate our launch, we are giving away two pieces from our line: a cement hat and cement stilettos.  Like our pearly white Sublime Cement®, these pieces offer both practical and aesthetic benefits. 🤠 With the hat, your head covering will stay put in even the highest of winds, keeping you protected from falling objects and simultaneously enabling you to strengthen your neck and shoulder muscles as you go about your day! 👠 And the stilettos! High heel shoes were originally designed to accentuate fine calves while preventing women from walking too fast or being too comfortable. Do you like to endure discomfort? Do you want your calves to get even more shapely? Do you need to slow down your walking pace to match that of your friends? Do you fear being blown away in the wind? If yes, then Sublime Cement® shoes are made for you! No sacrificing style for substance over here!  To enter, like, subscribe, and comment below on how you'd use Sublime Cement® apparel in your life!  #CementFashion #Innovation #Launch #Apparel #AprilFools

We would like to congratulate the winners of our internal Atlas and Athena Awards for the month of March! We look forward to continuing our acknowledgment of our employees’ hard work and breakthroughs as we drive our mission forward! The winner of the Atlas Award this month is Oscar Hover! After dedicating multiple weekends to leading test operations and assisting with R&D Workflow, transitioned to the Product Validation Team, ensuring both the state of the labs and accuracy of collected data are up to standard! For the Athena Award, our winner for the month of March is the Analytical Team! Since the team’s formation in late 2024, James Haddad, Mitchell Shapiro-Albert, Nathaniel S., and Anhtu Do have been major contributors to our improved measurement accuracy, data tracking, and ICP/XRF precision. Their work has provided essential data for Sublime to refine our process and product. Thank you to Jacob Doehring and Jesse Benck for the nominations and thank you to the winners for your outstanding contributions! #KeepBuilding #InnovationInConstruction #SustainableBuilding

Sublime set out to reimagine cement manufacturing for the next millennium by applying the core expertise of our founders, electrochemistry, to a process that has relied on combustion and high-heat kilns. Our co-founder Prof. Yet-Ming Chiang recently sat down with Shayle Kann from Latitude Media's Catalyst podcast for an episode appropriately titled, "An ode to electrochemistry." Yet gives an excellent primer on the field, explaining how “electrochemistry is powerful enough to break anything,” meaning that its infiltration into manufacturing can revolutionize how we make cement. Check out the full podcast at the link below to learn where else electrochemistry is making an impact! https://lnkd.in/eB7t544R

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
