Founder's GPT is a virtual tool designed to act as a mentor for startups. Leveraging the capabilities of OpenAI's language model, ChatGPT, it provides structured, stage-wise guidance for companies, from the ideation phase through to scaling operations. The objective of this tool is to offer critical support to entrepreneurs, especially those at the early stages of their startup journey. Users can reach out to Founder's GPT with a wide range of inquiries, indicative of the prompts made available: 'Need startup advice?', 'Facing a challenge?', 'Growing your business?', and 'Seeking funding tips?'. These prompts provide a starter point, encouraging interaction and facilitating the process of seeking advice and suggestions. In this way, Founder's GPT effectively serves as a ready source of business mentorship, providing insights that would typically be gained from a program like Y Combinator. Potential founders can obtain strategic support that can aid in avoiding common pitfalls and capitalizing on opportunities. It should be noted that access to this tool requires a subscription to ChatGPT Plus.
