Fabrica AI is creating a future where ideating and developing a robot for any task takes days, not years. We believe that by training end to end controls in simulation with reinforcement learning and above that iterating hardware designs, we can automate the whole development process. To validate our approaches for our AI system and to collect data, we invented an automatic tile grouting robot that boosts productivity by up to 5x and are piloting it on construction sites in Singapore managed by Woh Hup, BHCC, Gin Chia, Soilbuild, Chan Rong Fen, and Dragages. Tile grouting is the process of filling up the gaps between tiles after the tiles have been laid. We invented a patented robot that is able to automatically grout and clean tile gaps with only a press of a button. We’ve raised over 3m USD from Hoxton Ventures, Credo Ventures, our Professor from Cambridge University, Woh Hup, ffVC, and the owner of BHCC (listed construction company). We’ve 2500sqft of space in Singapore where we have over 20 team members, and 1200sqft of space in Czechia where we have our software team.

QuantrolOx, a University of Oxford spinout, is the developer of Quantum EDGE software for automated bring-up, characterisation and tuning of quantum chips. Quantum EDGE qubit automation software has set a new benchmark for speed and ease of use for qubit bring up, characterisation and testing with over 100x speed up compared to current industry benchmarks, thereby removing a major bottleneck in the rate of development quantum processing units (QPUs) and accelerating the path to developing practical quantum computers. It is the only quantum software company whose software is developed and tested 24/7 on a uniquely configured quantum computer ensuring that our software works “out of the box” to 70% of the solid-state quantum computers in the world. Quantum EDGE is designed to seamlessly integrate with the workflow of the QPU development and production processes in academia, research organisations and companies developing quantum chips. We envision a world where the bring-up, characterisation and tuning of every quantum chip will be fully automated enabling quantum scientists to spend less time testing and tuning qubits and more time advancing quantum computing, thereby accelerating the path to practical quantum computers. Quantum EDGE integrates with major quantum hardware providers by building on open-architecture principles enabling organisations to select the best components for their quantum systems.

The first US federally regulated exchange where you can trade on the outcome of any event. Kalshi’s historical regulatory approval from the CFTC enables it to offer a new asset class called “event contracts,” which allow traders to take positions on whether a future event will happen or not. Kalshi aims to enable investors to trade on almost anything with economic relevance from Covid numbers to whether a bill will pass in Congress, broadening the historical definition of what a commodity derivative is and paving the way for the futures market to catch up to the novel risks facing the economy today. Kalshi is backed by Sequoia, Henry Kravis, Charles Schwab, and Y Combinator.
