I am not certain, but I have been interviewed by several companies for internships lately (not sure if the hiring process for jobs are the same for internships) but the interviewer always seemed more interested in my projects outside of class than my school work and grades. So, it would seem that they would be highly impressed by attempting a startup regardless of failing or succeeding.
