Operand considers everything—competitor pricing, ad strategy, inventory, and more—to ensure businesses maximize profit. And unlike other AI solutions, every Operand result is verified by human experts, including ex-MBB consultants, so you get actual impact, not just AI hype.

Promptless integrates directly with your organization’s entire knowledge ecosystem – issue trackers, internal knowledge bases, support ticket systems, and more – leading to holistic doc updates without expensive coordination between product, engineering, and support teams. With Promptless, documentation becomes a strategic advantage for growth, not a bottleneck or a liability.

    Rocketable is building a large portfolio of wildly profitable software businesses by acquiring existing products and replacing human teams with AI agents. Today’s foundation models already possess enough intelligence to automate most of the tasks required to run a profitable software business. In the functions where agents aren’t yet intelligent enough to replace humans, they will be soon. When every human function required to operate a software product has an AI agent equivalent, the next step will be within reach: operating an entire company with a team of AI agents instead of humans. But superintelligent agents within each function won’t be enough. To operate a software company with 0 human employees, the agents will need to be directed towards common goals, integrated to collaborate across functions, tuned with feedback loops connected to product metrics, and trained to make resource allocation decisions. We are creating the tools needed to replace the entire org chart of a software company with a team of AI agents. We are developing these tools by owning the products that we automate, because we know from 10+ years of experience building automated systems with AI/ML that integration is the key to unlocking superhuman performance.

    We are building generative simulations of the world powered by fast world models. Instead of using a physics or game engine with hard-coded rules to render each frame and decide how the environment reacts, this is done end-to-end through a neural network. Unlike text-to-video models, our world models generate frames conditioned on actions, enabling real-time interaction with any environment. Users can explore, manipulate objects, and shape their experience through natural gameplay. We trained a model to emulate Minecraft that runs smoothly on consumer hardware (1B param model runs at 25fps on an nvidia 4090 gaming gpu while other Minecraft world models run at <3fps). Our advantage in speed comes from aggressive latent compression (128x) that allows us to encode every frame into only 15 tokens while others traditionally use 256. We are now training on real-world footage and are building a general-purpose universe simulator to power the next generation of video games and reinforcement learning gyms for robotics.
