How do you build the call graph? Is it language agnostic? I have a tool - https://carrick.tools - that works just in the Typescript space and extracting and reliably constructing the call graph has been a really complex problem in the TS/JS space.
Are you getting much traction within the cross-repo space? From personal experience, I know that the vast majority of products are poly-repo setups with often a monorepo core plus APIs, SDKs etc that sit outside that, but that means selling directly into B2B without any bottom up adoption which is challenging.
