You can copy/paste that into any Mermaid renderer to see it visually. Pretty wild how a British car brand ends up tracing back to Shanghai's government.Happy to run lookups for other companies if anyone's curious what their ownership looks like!
We found that going both up the chain and down / sideways in the chain was too much for the agent to handle - they are two distinct operations. The #1 use case was customers trying to understand the ultimate parent, so we decided to focus on that first.
We have something roughly working on subsidiaries, but it's not ready for prime time yet. It would likely be a separate API.
HN posts are such hit and miss. Do not be discouraged, this looks great.
As an example of HN hit and miss, I just posted a link to a reddit post regarding Claude Code, that could collectively save HN users many millions of dollars in the next week, and it has three upvotes at time of writing:
Regarding the product, I'm open to any and all feedback for your use case. Trying to follow the adage of "if you are not embarrassed by the first version of your product, you’ve launched too late".
And wow - just read your reddit post. I'm going to look into that for us too.
Your API, while using your MVP UI as teaching tool, is the #1 topic at my next meeting. The lesson about shipping early is so hard for me to execute, even though I know better. So, great job!
Also commenting so I can come back.
We actually haven't explored the big consulting firms yet. I know they are often contracted to do this sort of research for companies.
