It sounds like you’ve got a product that shows potential but needs more validation. I’d say keep testing with more users to get a clearer sense of demand. Even if growth is slow, if people are coming back and paying, it’s a good sign. Your strengths—speed, customer service, and customization—could be what sets you apart from competitors. It might take a bit longer in the B2B space, so don’t rush to scale too quickly. Just keep gathering feedback, fine-tuning, and testing. If it still feels right, keep pushing; if not, maybe it’s time to pivot. One more thing, the founder should not only be technical but also have domain expertise. This will help in understanding and building a product that people need.
