The AI assistant landscape is vast, with over 122 identified agents categorized into B2C generalized agents like Instinct and Muse, and more specialized ones for travel (Sora, Meso) or email. B2B workflow assistants also exist, functioning as executive assistants.
“So we have a bunch of long tail solutions out there. I think I'd categorize them into two groups. You have the B2C, consumer-facing generalized agents. That's like the Instinct or Muse, some of the longer tail ones.”
“And then we can break that down even further into a little more specialized within that. So you can have travel specific ones like Sora or Meso. You can have email specific ones.”
“The other side of the spectrum is going to be more of your B2B workflow type assistants. And those are anyone from Taelom to Tech to Vellom. And they're all essentially doing the same thing, right? They're your, like, more of an executive assistant, not the consumer-facing approach to it.”
“So far to my knowledge, there are 122 different ones across all the categories. Wow.”
