Tecto AI is my favourite, as it forms the "AI for AI" ouroboros. Outrove also sounds confusing, because doesn't Salesforce already purport to have their own native AI features? And when I look them up, it seems they're just AI for recruiting, which is also what VoiceOS purports to do.
Looking up the founders is fascinating too. So many of them seem to have graduated and immediately started trailing what appear to be a string of back-to-back failed businesses, rarely with more than a year of staying power per attempt. It's hard to tell if that's "failing quickly" (desirable) or "frantically trying to get-rich-quick" (undesirable and what I run into in Melbourne most often).
