Y Combinator announced Tuesday that it was doing away with pitch presentations from its largest cohort to date as fears about coronavirus continue to hobble young startups. The accelerator also moved the availability up to March 16 given investors' interest in speeding up the process, the company said in a blog post. The accelerator's twice-annual Demo Day is famous for its 2-minute pitches, usually delivered by founders or founding teams on stage to a room full of investors. Now, investors will have to sort through individual slides on each company on the accelerator's Demo Day website.
