HyLight logo

HyLight

Small unmanned hydrogen airships for long range monitoring

HyLight builds and operates autonomous airships for long range monitoring. We focus on detecting methane leaks on pipelines and defects on power lines. Our innovation, the HyLighter, is a crossover between drone and airship technology. Like a drone, it is easily controllable and transportable. And, like an airship, it is extremely energy-efficient, enabling it to fly for up to 10 hours at slow speed (22mph) for optimal data collection which represents a range of 220miles. Today, energy infrastructure operators struggle with conducting inspections that are simultaneously: massive and precise. HyLight offers a solution to precisely detect issues on the infrastructure at an industrial scale, and all of this without emitting GHGs. We are 3 co-founders experienced in hardware and energy companies with Masters in Mechanical Engineering, Computer Science and Business from the best Engineering and Business School in France. We have developed 5 different flying aircrafts and signed 5 pilots programs with major energy infrastructure operators. We also have LOIs worth over $3.5M.

Instacrops logo

Instacrops

Helping farmers maximize crop yield

Instacrops is a simple dashboard that helps farmers maximize their crop yield. We give farmers IoT sensors to put in their field. We combine that data with satellite and drone data to provide analytics on the health of their farms. Farmers use this to increase their crops yield by 12% on average. We’re live on 300+ farms across Latam and have reached more than $200.000 in monthly revenue, growing 2X YoY. There’s 2.9 billion acres of farmland in Latin America which makes this a $50 billion market. We’re instacrops. We’re bringing data driven decisions to farmers worldwide

Intelline

Intelline makes the world's most efficient fuel agnostic engines for…

Intelline makes fuel agnostic engines for practical, clean, and low-cost industrial power. Our first customers are in data center energy infrastructure and oil & gas production. Our engine generate electricity with even the most difficult fuels like flare gas, while reducing fuel OPEX by 40%. There are 1,000,000 new heavy duty engines produced per year, and at an average $50k per heavy duty engine this is a $50B market opportunity. Our generator can efficiently run emerging fuel types that traditional diesel engines can't use (flare gas, syngas, ammonia, hydrogen), and can switch between fossil fuels and any other liquid/gaseous fuel while running. Full size running prototype successfully tested April 2025.

Inversion Semiconductor logo

Inversion Semiconductor

Manufacturing the most powerful chips, 15x faster

Inversion Semiconductor is developing the next-generation chip fabrication machine, to create the most powerful chips 15x faster. Our vision is to reshore advanced chip fabrication capabilities in the West. We're building a lithography machine. Lithography uses light to pattern circuit features on silicon. We're scaling transistors to their physical limits by shrinking particle accelerators 1000x, to create a high power light source. Using our light source we will double transistor density for a given numerical aperture and 3x throughput.

Ionworks logo

Ionworks

Simulation software used by leading battery and automotive companies

Every battery company spends tens of millions of dollars a year on experiments. Simulations that replace experiments reduce these costs but are currently underutilized in industry because they are hard to create and run. We make simulations accessible to every engineer, by helping them to create models from their own data, then run large scale simulations in the cloud to explore the full design space.

Kisan Network logo

Kisan Network

Tech enabled and fully integrated PAN India agri produce supply chain

Kisan Network is a tech enabled and fully integrated PAN India agri produce supply chain. We connect small and marginal farmers directly to businesses anywhere in the country, with each step digitally captured and monitored on our proprietary management portal. As a result, farmers are able to earn 10% more than prevalent market prices for their produce. Our system, built on the 3 pillars of  1) 100% integration 2) Standardisation w.r.t. on-field practices and, 3) Transparency for all stakeholders is a departure from the opaque and inconsistent traditional supply chain which thrives on the high levels of fragmentation in the ecosystem. There is 0% use of paper in our entire chain, with specific focus on building a national agri repository of micro level stakeholder information and on image / data driven automated crop quality assessment.
