Change of business idea under startup to Innovator Founder

Hello Everyone,

Has anyone changed their business while in the Startup route and have applied under new business criteria for the Innovator founder route through a legacy endorsing body? Please let me know what questions are being asked by the Home Office.

My first startup endorsed through the legacy body failed and did not take off, so I had to switch to another Idea and apply under New business criteria under the Innovator founder route also supported by the legacy body.

Do you all know what questions are asked by the Home office for the same?

What I can think of are as follows

1.) Why do you think the new idea will work? Any data that represents the same?
2.) Reasons for failure for the 1st Idea.
