Hi People. I'm curious to know about few things. If you are a founder building a saas / service business & figured out the product market fit then, How did you validate your idea? ( I'm not asking validating using LLMs ) Are there any frameworks you used for this? How did you fill the business model canvas with the right details. How did you find your 1st few (5) customers. Really curious about these things and i think it will help someone as well. So, please answer ...
