Claybird's AI Agents Script the Ad for Coca-Cola and Walmart

The YC-backed startup is betting that brands will trade weeks of human production for 72 hours of AI-generated video, using models like Sora.

About Claybird

Published

The brief is simple: a 30-second spot for a new mattress, targeting young professionals who work from home. You type a few lines about comfort and quiet into a text box. Seventy-two hours later, a video lands in your inbox. It has a script, a voiceover, and a sequence of shots showing a person sleeping peacefully while a laptop glows, ignored, on a nightstand. The lighting is soft, the cuts are clean. It looks, for all intents and purposes, like an ad. This is the promise of Claybird, a San Francisco startup that is trying to become the first full-stack AI agent for video advertising. The company, founded in 2025, takes a marketer’s prompt and claims to handle the entire production pipeline,planning, scripting, generating video with models like Veo or Sora, editing, and delivering a final cut,in under three days [Reforgers, 2025]. Their early client list, which includes Coca-Cola, Walmart, and Eight Sleep, suggests some brands are already willing to test the premise [Reforgers, 2025]. The bet is not just on faster video, but on a new kind of creative supply chain, one where the brief goes directly to the render farm.

The Wedge Against AI Slop

Claybird’s founders, Saad Jamal and Abdullah Nauman, are positioning their tool against what the industry has started to call “AI slop”,the uncanny, low-quality output from generic text-to-video tools. Their wedge is a claimed focus on studio-quality output, achieved by chaining together specialized AI agents. One agent might handle script reasoning, another might manage shot composition using Neural Radiance Fields (NeRFs) for consistent 3D scenes, and another could evaluate the final edit [Reforgers, 2025]. The goal is to inject a layer of creative direction and technical polish that raw model output lacks. For a brand manager, the appeal is obvious: speed and cost. A traditional video ad shoot can take weeks and cost tens of thousands of dollars. Claybird’s SaaS model promises to collapse that timeline and expense into a subscription service, enabling rapid iteration for A/B testing or localized retargeting campaigns [Fondo, 2025]. The company’s backing from Y Combinator’s Fall 2025 batch provides a strong early signal, though the seed round amount remains undisclosed [Y Combinator, 2025].

The Team Building the Creative Assembly Line

The founders bring a mix of technical and applied AI experience to the daunting task of automating a creative field. Saad Jamal, the CEO, worked on machine learning infrastructure for Tesla’s Autopilot system and, notably, trained reasoning models with Ashish Vaswani, a lead author of the seminal “Attention Is All You Need” paper that underpins modern AI [Y Combinator, 2025]. This background in high-stakes, real-world AI systems suggests a focus on reliability and evaluation. Abdullah Nauman, the CTO, has previous roles at Google and the University of Michigan, rounding out the technical foundation [RocketReach, 2026]. The team is small, reported at just four employees, which is typical for a YC company at this stage but underscores the ambition of their automation goal [Y Combinator, 2025].

Where the Render Might Stutter

The risks for Claybird are as vivid as the opportunity. The entire model rests on the rapidly evolving but still imperfect foundation of generative video AI. While Sora and similar models produce stunning clips, they struggle with consistency, physics, and brand-specific details like accurate logos or product colors. A brand like Coca-Cola has meticulously guarded visual assets; an AI hallucinating a slightly wrong shade of red or a wobbly script logo could be a non-starter. Furthermore, the competitive landscape is crowded with well-funded players aiming at different parts of the same problem.

  • The incumbents. Tools like HeyGen focus on AI avatars and spokesperson videos, while others like Icon or Arcads offer templated ad creation. Claybird’s differentiation is its end-to-end, agentic approach, but it must prove its output is qualitatively better, not just faster.
  • The in-house option. Large brands with deep pockets could simply license the same underlying video models from OpenAI or Google and build their own internal pipelines, cutting out the SaaS middleman.
  • The creative ceiling. The most potent risk is aesthetic. Can an AI agent, no matter how well-chained, truly replicate the nuanced creative decisions of a human director and editor for a brand’s flagship campaign? For now, Claybird may find its strongest product-market fit in performance marketing,retargeting ads, social media clips, and other high-volume, lower-stakes video needs where speed and cost trump cinematic perfection.

The next twelve months will be about proving that the brands on its roster are moving beyond experimentation to production. The questions are practical: What is the actual throughput? What is the renewal rate? The company has successfully framed its ambition. Now it must demonstrate that its assembly line doesn’t just produce video, but produces ads,assets that move product and build equity. The deeper question Claybird is asking, one that extends far beyond its own dashboard, is whether the craft of persuasion can be systematized. It’s betting that for an increasing share of the video economy, the answer is yes, so long as the system is fast, cheap, and just good enough to not look like it came from a machine.
