Aeroseal is a climate tech company on a mission -- reduce the world's carbon emissions by 1 gigaton annually. How will we do it? With our leak sealing technologies. Small leaks are a BIG problem -- The ducts and walls in buildings are inadequately sealed by manual solutions. Aeroseal’s technologies - HomeSeal Connect and AeroBarrier Connect - inject a fog of sealant particles into these pressurized spaces. Software tracks the entire process, creating a certificate of completion showing before and after leakage.

Albedo is developing low-flying satellites that will capture visible and thermal imagery at the highest resolution commercially available. By making aerial quality imagery globally available, easy to purchase, and transparent to task, we aim to catalyze market growth and spur new applications. The world is rapidly changing and a new level of visibility and transparency is required to solve some of our largest problems. Albedo’s 10cm visible and 2m thermal imagery will fuel insights for industries such as mapping, insurance, utilities, solar, agriculture, carbon offsets, infrastructure sustainability, national security, and much more.

In a rapidly changing world, today’s problems can’t be solved with yesterday’s solutions. Our biggest challenges keep get bigger, but we can’t keep up with our feet on the ground. At Albedo, we believe that space is more than just a place to explore — it’s also a tool that can be used to help tackle problems here on Earth. Our exquisite imagery empowers industry leaders with the details that matter so that we can support what we have and shape what we don’t. With a new perspective, we can change the big picture.

Concrete is the most widely used building material on our planet. The only thing mankind uses more of is water. With a wave of urban development coming in the next few decades, concrete is also a rapidly growing trillion-dollar market. However, cement and concrete production is responsible for 8% of the global CO2 emissions, making its growth a big cause for concern. Low-carbon concrete exists - but until now it has been too sophisticated to be produced reliably and on a large scale. It contains very little burnt limestone - responsible for the strength of concrete and CO2 emissions. This makes low-carbon concrete vulnerable to fluctuations in raw materials and operating conditions and thus difficult to produce with reliable quality. Adding to the challenge: the final quality of concrete can only be measured weeks AFTER it has been processed on the construction site - far too late to be corrected. This is why our world is still built on more robust, high-carbon concrete. Using alcemy's software, cement and concrete producers receive precise quality predictions already during production. Based on these prediction models, our AI identifies which production parameters need to be adjusted to mitigate the impact of fluctuations. Thus, the quality of cement and concrete can be optimized BEFORE delivery – for the first time in history. The result is significantly more consistent product quality, allowing producers to safely replace burnt limestone with less expensive, low-carbon materials found in nature. In this way, they can also avoid payments for CO2 emission certificates in the EU. Saving costs, bringing production processes up to speed for 21st century concrete recipes, and saving half of Europe’s CO2 emissions goes hand in hand at alcemy. Join us on our journey to make low-carbon concrete a reality!
