I have come across several statements such as: a single person cannot raise money on their own (you need to be in a team of at least 2 people), it is not worth it because there is pressure on you, etc.

• What is your experience with raising money?

• What did it give you, and who did you raise it from?

• What do you think helped you to a large extent to get the raise?

me and my co-founder are building an AI agent because at our last startup we just couldn t keep up with support.

we tried every chatbot out there. they all felt robotic. customers hated it.

hiring more people was too slow + too $$$

so we put together this ai chatbot (think intercom fin but deeper) that trains on your old tickets, learns your tone, doesn t hallucinate, and can actually answer stuff like a real support rep.
