Delve faces open-source fork allegations

Y Combinator-backed compliance startup Delve is facing new allegations that it repackaged an open-source tool as its own product without proper license attribution, according to TechCrunch. An anonymous whistleblower known as “DeepDelver” claims Delve pitched a no-code product called Pathways that closely matched Sim.ai’s open-source agent-building tool SimStudio, and later presented alleged evidence that Pathways was a fork of SimStudio with minimal changes. Sim.ai CEO Emir Karabeg told TechCrunch there was no license agreement with Delve and that Sim.ai had tried unsuccessfully to sell Delve an agreement.

If the allegations are accurate, the issue is not that Delve used open source—open source is designed to be reused—but that it treated the legal obligations as optional. TechCrunch notes the code in question is under the Apache license, which typically requires preservation of copyright notices and attribution and includes conditions around notices and modifications. For a company selling “compliance” as a product, the accusation is unusually specific: the business is meant to reduce customer audit and governance risk, yet its own product development may have created exactly that kind of risk.

The second-order problem is supply-chain contamination. Startups increasingly ship fast by assembling products from existing repositories, SDKs, and templates, then layering a UI and sales motion on top. When a vendor fails to comply with open-source terms, downstream customers can inherit the mess: they may deploy software with unclear provenance, face takedown demands, or be forced into rushed rewrites during procurement reviews. That is particularly acute in compliance and security tooling, where buyers expect clean documentation, repeatable builds, and defensible IP posture.

The Delve-Sim.ai relationship also underlines how incentives work inside accelerator ecosystems. TechCrunch reports that Sim.ai was a Delve customer—money flowed from Sim.ai to Delve—while Delve allegedly used Sim.ai’s open-source code without a commercial agreement. In a tight network where alumni sell to each other, reputational damage can spread faster than formal enforcement. TechCrunch also reports that references to the Pathways tool and other pages appear to have been scrubbed from Delve’s site, and that Delve did not respond to a request for comment; the media inquiries address on its website no longer works.

The whistleblower alleges the behavior preceded a $32 million Series A led by Insight Partners, and TechCrunch says it contacted the firm about its diligence process. An investment blog post cited by TechCrunch was briefly unavailable.

The license dispute is now being litigated in public, while the product pages vanish.
