To build a SaaS product from scratch, I start by identifying a problem that needs to be solved in the market and conducting research on the target audience.
Then, I create a minimum viable product (MVP) to test the idea with potential customers and gather feedback. From there, I continue to iterate and improve the product based on customer feedback.
I also prioritize building a strong team with diverse skills and expertise, as well as creating a solid business plan and marketing strategy to reach potential customers.
As for tips, I would suggest being open to feedback and continuously adapting the product to meet the needs of the target audience.
