Corgi, a YC-backed insurtech startup, is embroiled in an open-source plagiarism controversy over its newly launched Dataroom product. The company denied to TechCrunch that it copied Papermark’s code but acknowledged that, during AI-assisted development, certain pages’ visual and functional designs were too similar to existing products.
The dispute arose with the launch of the Data Room.
Marc Seitz, co-founder of the open-source data room software Papermark, accused Corgi on X of taking credit for its product and releasing it under its own brand. He further claimed that this practice involves copyright and license violations, and even constitutes "fraud."

Corgi's co-founder and CEO, N, issued a follow-up statement saying the company has reviewed the code and found that the underlying code of the two products is not identical. He emphasized that whether code was copied is a separate issue from whether a product's design style was inspired by existing products.
The company acknowledges that the page design is similar.
Laqua also acknowledged that the team relied on "vibe coding" during development, resulting in high similarity in visual language and certain features. He stated that the team should have relied more on their own creative expression rather than drawing excessive design inspiration from similar products.
A Corgi spokesperson stated that the issues were primarily focused on visual elements on two edge setting pages, which have been immediately corrected. The company reaffirmed that no code from Papermark was used internally.
AI programming sparks new controversy
The controversy has continued to escalate not only because the two companies have been blaming each other, but also because it raises a real issue in AI-assisted development: when tools can rapidly replicate the structure, interface, and functionality of another product, is different code enough to draw a clear line?
The report notes that, from a legal standpoint, whether the code is identical remains the key criterion, making this case distinct from the 2024 PearAI incident, which involved direct cloning of open-source projects. However, on an industry ethics level, similar disputes may become increasingly common.
Corgi has sent a legal notice.
To mitigate reputational impact, Corgi has sent a cease-and-desist letter to Seitz, demanding the removal of the relevant posts. Meanwhile, the company has continued to attract external attention due to comments about its intense work culture, as well as consecutive rounds of fundraising and rapid valuation increases in a short period.
- Completed a $106 million Series B1 funding round last month.
- The company's valuation has increased to $2.6 billion.
- Just announced a $160 million Series B funding three weeks ago.
