From the article: I decided to leave Intuit and fundamentally improve communication in a way that would obsolete notebox.

Sounds like notebox and CompanyLine are two different products that don't necessarily share code.

The two product are not related. Every VC/Angel so far has asked about that topic. Thanks for reading the post!

It sounds as if CompanyLine was the product "you really needed at your previous employer". This is exactly what PG recommends for startup ideas. Good luck!

How can you tell? All I can find on the website that even comes close to explaining what it is/does is:

"CompanyLine is fundamentally improving the way companies communicate."

and the even less helpful:

"CompanyLine enables conversations that solve real business problems."

What does that even mean?
