Corgi, the buzzy Y Combinator-backed insurance tech startup, says it didn’t steal an open source product

Y Combinator-backed insurance tech startup Corgi has become embroiled in controversy after Papermark, maker of open source data room software, accused it of stealing its software. The allegations, made by Papermark co-founder Marc Seitz on X earlier this week, claimed that Corgi’s newly released Dataroom product copied Papermark’s source code and violated its license. Corgi denies the accusation, stating that no code was used from Papermark.
Corgi, a two-year-old insurtech company, launched Dataroom as a secure document sharing tool for startups to share materials during fundraising and due diligence. Papermark provides a similar open source product. Seitz’s post included screenshots showing identical language for the same features, word for word, leading him to call Corgi’s product copyright-infringing and “fraud.” The post quickly gained traction on social media.
Corgi’s CEO Nico Laqua responded on X with a full denial, showing that the code differed between the two products. He admitted that the design was “vibe-coded,” meaning it replicated existing products’ style without copying code. A Corgi spokesperson told TechCrunch that the offending visual elements were isolated to two peripheral settings pages and have been immediately updated. They emphasized that no code was copied.
The incident raises thorny questions about vibe coding, where AI tools can replicate the look and feel of another product without copying lines of code. Legally, copyright infringement requires copying of the code itself, so this case may not meet that threshold. Morally, however, the ambiguity is significant. Dan Barrett, YC alum and founder of OpenProse, noted that as bots can trivially reproduce structure, traditional IP law may be inadequate.
Laqua accused Papermark of making the accusations because Corgi offers a mostly free product that competes with Papermark’s SaaS. “I get that this stings since we’re putting out something mostly free that competes with his SaaS. I’d be mad too,” he wrote. Seitz did not respond to a request for comment. Corgi has sent a cease-and-desist letter to Seitz demanding removal of the tweet. Separately, a coffee shop competitor received a cease-and-desist for a joking tweet about the controversy.
This is not Corgi’s first legal conflict. In May, competitor Matcha accused it of bullying, and the startup has sued former employees. The company now works to mitigate reputational damage. As vibe coding becomes more prevalent, the tech community watches how intellectual property norms evolve. Startups may need clearer guidelines on acceptable design inspiration versus infringement in an AI-driven development environment.
