I transitioned into cancer immunotherapy research after Computer Science grad school. Biology is a mess and it will take several years to get up to speed on any one research area. The best options are either grad school or finding a job which doesn't initially require a lot of bio background but provides the opportunity to learn. It's also worth checking out local biohacker spaces, they can teach some basic techniques but you'll hit a ceiling quickly. To really "start a biotech company" you'll really need to spend a long time outside your comfort zone.
