How would that help precisely? You should put more effort in hiring, if you're worried about developers not understanding how to help a company grow. In the past I worked for startups and very small startups. The wannabe-corp ones have goals, the real ones don't. They want to stay afloat and grow as well, but transparency is enough motivation for devs to do their job: we need the MVP or we sink, all of us.

Genuine question: do you have experience in management with OKRs? Do you have some examples proving they helped in your career? Even made-up examples, just to understand what people expect from OKRs.
