Is there an alternative to IT outsourcing in Healthcare?

Hello everyone I have a question. Maybe someone has faced such a problem? Our team has an MVP Medical product, but to create a more scalable version in the shortest possible time, we need to hire additional developers. This is very expensive, since it's not just about their salaries, but also about the search process itself. It's a very long time. Outsourcing teams are one of the options that come to my mind. But without micromanagement, I am afraid that they will not fully understand the idea of the product or there will be people in their team who do not understand the medical field. Developing with the current squad is a matter of time. Competitors may overtake or even worse motivation may disappear. What are the options for solving such a problem?
