Ask HN: What are some good startups that a CS grad student should intern at?

My thinking on what could make a particular startup a good place to intern would be - 1. It has a strong engineering team, so the internship provides good learning and an opportunity to build good network. 2. The product is exciting and requires strong CS skills (as opposed to one that requires stronger marketing) 3. The startup is doing good, so there's a possibility of future full-time job.
