Building an in-house tech team requires significant investment of time, money, and resources. It can take 50-120 days on average to hire each new employee, and salaries for full-stack developers in the US are around $115,960 annually. Factoring in hiring costs, benefits, retention costs, and the risk of poor hires, the true cost of building an in-house tech team can be substantial for startup founders. Outsourcing hiring to agencies can expedite the process but costs 15-30% of the new employee's annual salary. Overall, building a strong in-house tech team requires patience, skills, and a willingness to invest heavily in recruiting and retaining qualified software engineers.
