Ad Army

YCombinator

Generate, iterate, and ship AI ad creatives faster

Ad Army is an AI creative tool for brands that need a constant supply of ad creative. You build your brand's world once — characters, products, locations — each with locked descriptors and reference images. Then you generate against it: @-mention an entity in a prompt and its references are pulled into the model call, so the same product, the same face and the same location hold across images, video, and dozens of variants. Save any chain of steps as a recipe and replay it on the next campaign. We're model-agnostic by design — video, image, text and audio providers sit behind one interface, and new models land as they ship. For a full narrative spot, the same world scripts, storyboards, animates, voices, captions and exports multi-scene ads in every aspect ratio.

Real-time AI Compliance & Revenue Integrity for Medical Providers

US healthcare providers lose billions every year to denied claims, most of them traced back to documentation and coding gaps no one catches until the payer says no. Adentris is an AI revenue integrity platform that catches them first. Our AI agents read EHR and payer interfaces directly, no API integration required, across five modules: documentation, coding QA, prior authorization, appeals and denials, and discharge summaries. And for providers that don't have their own CDI or billing teams, we run billing as a service on top of the platform.

Modernizing Chip Manufacturing Infrastructure

We are building the future of chip manufacturing. Chips are more advanced than ever, and the features inside them keep getting smaller. But the cleanroom infrastructure supporting their manufacture has not scaled at the same pace. Intel, TSMC, Samsung, and others spend billions building and operating massive cleanrooms, only to isolate their most advanced wafers from the surrounding facility as much as possible. We think that architecture is backwards. Instead of making the entire building cleaner, why not make the machinery itself as clean as possible? Talos is our proprietary tool-integrated purification system. It sits directly inside semiconductor equipment and continuously destroys airborne molecular contaminants before they reach the wafer. Instead of fighting contamination by constantly flooding tools with ultra-high-purity nitrogen, Talos keeps the environment inside the machine 10–100x cleaner, without the massive purge-gas bill. Talos is powerful on its own, but it is also the foundation for a much bigger vision: the Cleanpipe. The Aerogen Systems Cleanpipe is an ultra-clean interconnect infrastructure that protects wafers as they move from machine to machine across the fab. Rather than relying on a billion-dollar cleanroom to protect every cubic foot of factory space, Cleanpipe creates a controlled environment only where cleanliness actually matters: around the wafer. Talos cleans the tools. Cleanpipe connects them. Eventually, we delete the cleanroom and build more advanced chips, at greater scale, with radically less infrastructure. With cleanpipes connecting tools, chip fabs can exist anywhere.
