An in-house team buys you the deepest product knowledge. The engineers absorb your domain in a way no external team will match, and that knowledge sits with you. The cost shows up as time and rigidity: filling a senior mvp development cost role is slow, getting someone productive takes several more weeks, and the cost continues through the quiet quarters.
Project outsourcing means someone else is accountable for shipping: they staff the roles, they manage the plan, and they absorb the staffing risk. This works well when the work is a defined project and your side has an available product owner. It fails when there is no one to answer questions, since the provider cannot guess what the business wants.
Hiring individual contractors is the middle option: you rent capacity while keeping the planning and the management in-house. The main advantage is speed — a suitable engineer is often available almost immediately — and it scales down as easily as it scales up. The catch remains that your engineering managers have to have the capacity to direct the work. If that capacity is missing, you are paying for hours, not results.
Most of the time, companies blend them. A frequent arrangement holds architecture, product decisions and core domain code in-house, while a partner handles discrete features, migrations or mobile clients. The principle is simple enough: retain what differentiates you, and outsource what is well understood.
A few questions usually settle it. Start here: is this software development company in london central to how you make money, or a cost centre? Then: over what horizon will you need this capacity — a quarter or a decade? Finally: who will maintain it in two years? Work through them with real answers and the right arrangement is normally clear.
