Founders should tell something about development. How do you consider its potential and whad do private investors think about process in general? To my mind you have good concept , but lack of development.
I would share more proofs. Do you have github with updates?
Why did you decide that the team stopped its work and does not develop the project? Sometimes the implementation of a single point of the Roadmap can take a lot of time. Behind the scenes work continues.
It happens differently. I remember one small team that had few people in the team. And when they conducted ISO, they rarely gave answers to the questions they left in the forum topic. But they very quickly created their product and began to work in the market. And for each of their steps, they did not report to investors.
