Is it agism? I don't know for sure even though I'm old (>30). There are various scenarios I've seen. Startups want people with little to no experience so they can work ungodly hours as they don't have families. These in my experience tend to have a young CEO who doesn't like being contradicted or challenged from more experienced folk.
Things like web development is such a copy & paste factory that I equate that like working fast food. You get years of experience so become too expensive. They only want to hire more folk with limited experience cheaply. There's no call for too much experience as that is aged quickly when new techs come along.
Some larger companies have older folk there and it's easier to get into those type roles. In my experience their non-web related mostly where specialization is needed. I think there are roles for older folks when they move from the web centric factory roles.

All just my experience.
