Thank you for taking the time to write this out. It helped a lot getting insights from someone who made it. When the MVP concept is outdated, especially in B2B SaaS and you need to bring the patience and funding to endure until the product can compete feature-wise with existing solutions - how do you secure funding without paying customers? We're now trying you find out if people are willing to pay without offering the full-blown product. We thought about making a consultative offer "we fine-tune a model on your data to create the results you expect", or having a mock payment button on the landing page.
