A buzzy insurance technology startup is pushing back against accusations that it built its product on someone else's code.

According to TechCrunch, Corgi — an insurtech startup backed by the prominent accelerator Y Combinator — became embroiled in controversy after a company called Papermark accused it of stealing its open source software. Corgi says it did not.

The denial, TechCrunch reports, raises new questions about "vibe coding," the loose term for building software quickly with heavy reliance on AI assistance. When code is generated rapidly and assembled from many sources, it can become harder to say with confidence where a given piece of software actually came from — and whether borrowed open source work was used in ways its creators didn't intend.

Open source software is code that is published publicly and free for others to use, but typically under licenses that set conditions on how it can be reused, copied, or commercialized. An accusation of "stealing" open source generally means those terms were allegedly ignored, not that anything was taken in secret.

The dispute pits a smaller player, Papermark, against a startup that carries the credibility and visibility that comes with Y Combinator's backing. Per TechCrunch, the core facts remain contested: Papermark has leveled the accusation, and Corgi has flatly denied wrongdoing.

Why it matters: As AI-assisted "vibe coding" makes it faster than ever to ship software, this fight is an early test of how the tech industry will sort out credit, ownership, and the rules of open source when code can be spun up in a hurry.
