Corgi Denies Open-Source Code Theft After Marc Seitz Accuses Dataroom Copying

Y Combinator-backed insurtech startup Corgi became embroiled in an open-source plagiarism controversy after Papermark co-founder Marc Seitz accused Corgi on X of taking credit for its Dataroom product and releasing it under its own brand.

Corgi denied to TechCrunch that it copied Papermark’s code, telling the outlet “No code was used from Papermark,” while acknowledging that AI-assisted development led to page designs that were too similar to existing products.

TechCrunch reported that Seitz’s post “shared screenshots showing Corgi’s product using the same language for the same features as Papermark’s, word for word,” and Corgi’s co-founder and CEO Nico Laqua said the underlying code was not identical.

Laqua also admitted that the team relied on “vibe coding” during development, which he said resulted in high similarity in visual language and certain features, and a Corgi spokesperson told TechCrunch that the problematic elements were changed.

Corgi said the issues were isolated to visual elements on two peripheral settings pages and that they were “immediately updated,” while the company also sent a cease-and-desist letter to Seitz demanding removal of the relevant posts.

In response to Seitz’s accusations, Corgi issued a follow-up statement and told TechCrunch it had reviewed the code and found that the underlying code of the two products is not identical.

Laqua argued that “stealing code and copying a design style are two different things,” while also posting that “Looking back, we should’ve leaned more into our own language and visual choices instead of taking cues from existing products in the space, and that’s on us,” according to TechCrunch.

TechCrunch framed the dispute around a new question raised by vibe coding: if tools can replicate structure, interface, and functionality without copying every line, how much does it matter whether the source code is identical.

Dan Barrett, described by TechCrunch as a fellow YC alum and founder of the agent operating system OpenProse, weighed in on X by asking, “what makes one unacceptable and the other not? existing IP law, incidental to the old world? is there not some greater principle at work here?”

TechCrunch also reported that Corgi confirmed it issued a cease-and-desist letter to Seitz demanding he take down the tweet, and that the founder of Hello World Cafe said he received a similar letter after joking about the controversy.

While the open-source dispute played out online, Corgi’s fundraising momentum and valuation climbed quickly, with KuCoin’s report saying the company completed a $106 million Series B1 funding round last month and that its valuation increased to $2.6 billion.

KuCoin also said Corgi “Just announced a $160 million Series B funding three weeks ago,” adding to the pressure around how fast the startup was moving while the Dataroom controversy escalated.

TechCrunch reported that Corgi was “vigorously trying to clean up any reputational damage” and confirmed it had issued a cease-and-desist letter to Seitz demanding removal of the tweet.

The TechCrunch account also said Corgi had a growing reputation for being litigious, noting that Laqua said the startup had already sued various former employees.

In parallel, TechCrunch described how Laqua went viral on Harry Stebbings’ podcast for expecting employees to work seven days a week, quoting him as saying, “Whatever you can get done in five days, I promise you, you’ll get more done in six and seven,” as the company faced broader scrutiny.
