Ask HN: Any companies offering tech internships to high schoolers?

Hi HN, I'm in high school right now and am looking for a (preferably tech-related, as that's my main current skillset that would be of interest to a company) internship for this summer. I did find a couple from "major companies": google, microsoft, and facebook, but I'm for various reasons ineligible for those programs. Does anyone know of companies offering internships I might be able to apply to? Preferably in/near san fransisco, as I have a relative there I can stay with.
