Building your own team buys you the most control. The developers internalise your domain over time, and that accumulated context remains inside the company. The cost is time difference between flutter and react native rigidity: hiring well takes months, ramping up adds more time, and the payroll keeps running whether the roadmap is full or empty.
Full outsourcing implies the vendor owns delivery: the provider staffs the team, they manage the plan, and they carry the delivery risk. The model works when the outcome can be described and there is a decision maker with time for it. It fails when nobody on your side owns the product, as the provider will not invent your business rules.
Team extension falls in the middle: you rent capacity while keeping the planning and the management yourself. The main advantage is speed — a suitable hire laravel engineer can join almost immediately — and it winds down as quickly as it ramped up.

Third: who will maintain it in two years? Answer these three honestly and the right arrangement usually chooses itself.
