Delve accused of forking Sim.ai's open-source SimStudio and selling it as Pathways

Delve, a Y Combinator-backed compliance startup, faces new allegations that it forked an open-source tool and sold it as its own product without proper attribution or licensing. According to a TechCrunch report based on whistleblower claims, Delve pitched a no-code tool called Pathways to a prospect who later became the whistleblower known as DeepDelver.

Key allegations from the source

The whistleblower DeepDelver recognized that Delve's Pathways tool looked similar to Sim.ai's open-source agent-building product called SimStudio. When asked if Pathways was based on SimStudio, Delve representatives reportedly claimed they built it themselves. DeepDelver then presented evidence suggesting Pathways was actually a modified fork of SimStudio, changed just enough to be passed off as Delve's own work.

If true, this would violate the Apache software license, which requires proper attribution to the original developer. Sim.ai's founder and CEO Emir Karabeg confirmed to TechCrunch that Delve had no license agreement with Sim.ai. "We knew they planned to use Sim for something and later tried unsuccessfully to sell them an agreement," Karabeg said. "I didn't realize they were going to sell it out of the box as a stand-alone solution."

Additional context from the source

• Sim.ai was actually a Delve customer, with both companies being Y Combinator alumni
• Delve allegedly used these methods preceding its Series A funding round led by Insight Partners
• Insight Partners' 2025 blog post about its $32 million investment in Delve was temporarily unavailable from the VC firm's website
• Mentions of the Pathways tool on Delve's site appear to have been scrubbed
• Delve did not respond to TechCrunch's request for comment, and the media inquiries address on its website no longer works

This situation highlights the importance of proper open-source license compliance, particularly for companies selling compliance solutions. The Apache license requires attribution when using or modifying open-source software, and failure to comply can damage both technical and business reputations.
