An attitude towards 'failure' is very important and often determines how the society accepts innovation all together... In many successful places failure is like a shevron of experience - and that's how it should be. So you are much better off after your first startup failed.
But if you know that your audience is seeing it differently, then better not to approach them right away. Otherwise you will be caught in discussions 'how is this one is better than that other one'... And this is a waste of time:(
