In addition to the excellent advice here:

Take a moment and feel really good about the work you did, even if the company didn't succeed. Celebrate that you probably contributed a lot to making a small startup survive for as long as it did. Acknowledge that was in some part due to you, and then write down the things you felt most proud of.

Keep that paper with you every time you interview, so you are reminded that you did good work, and have a positive story about why you will bring a lot of value to your next role
