Ask HN: Is 25 too old to get your first job at a startup?

I live in Los Angeles and I don't have a ton of prior work experience. I worked at a PE type shop for ~8 months and then started pursuing a skillset in technology. I have a BS in Economics and minors in Marketing & Biz Admin (so not tech related at all). I taught myself html/css/sass and am pretty capable with JS and JQuery. I am doing a 3 month bootcamp so I can polish my skills and learn Ruby and about a few different databases. When people come out of these bootcamps they end up working at small web dev shops and frankly that isn't very compelling to me. I want to work for a start up but am worried I am too old for entry level and possibly won't have the right skillset. Anyone have experience interviewing or hiring someone like this?
