You could think about skills development in a T-shape form where your employees can acquire more depth in their skillset or go broad. More depth would mean developing their technical ability, going from junior developer to architect of smaller size applications to massive applications or developing mastery in certain technologies. More breadth would mean providing them with a path that lets them develop their managerial skills, technical or non-technical, eventually equipping them with skills to run their own technical teams, driving sales, become partners in the business, etc. A consideration would also be to have an honest conversation with your team and where do they want to grow their careers. Though they might churn to startups or enterprise companies, treating them well could result in referral business.
