Outsource when the work is well-specified, temporary, or you lack engineering management. Build in-house when engineering is your core product, the roadmap is continuous, and you have someone to lead it. Most mid-sized companies end up hybrid: a small in-house core with outsourced capacity around it.
The comparison is usually framed as cost, which is the least interesting variable. The decision turns on whether you have someone who can manage engineers.

Where most land
Outsourced: one to two weeks. In-house: two to four months to hire, then months to ramp.
In-house is a fixed cost that is difficult to reduce. Outsourced is variable and stops on notice.
In-house accumulates deep context over years. This is the strongest argument for it.
Both need direction. In-house also needs career development, performance management and retention work.
In-house keeps it, unless people leave. Outsourced keeps it only if documentation is contractual.
Outsourced scales both directions on notice. In-house scaling down means redundancies.
| In-house (US senior) | Outsourced studio | |
|---|---|---|
| Monthly cost | $12,000 – $18,000 loaded | $3,500 – $6,500 |
| Recruitment | 15–25% of salary | None |
| Time to productive | 5–9 months total | 2–3 weeks |
| Ramp cost | $48,000 – $80,000 | Minimal |
| Scaling down | Severance and process | 30 days notice |
| Management overhead | High — reviews, growth, retention | Moderate — direction only |
| Context after 2 years | Excellent | Good if documented |
The cost gap narrows over years as in-house context compounds. It is widest in the first twelve months, which is exactly when most companies are least certain about the roadmap.
When software is the product, the roadmap is permanent, and you have an engineering leader.
Most mid-sized companies land here: one or two in-house engineers who own architecture, product context and code review, with outsourced capacity for delivery volume. The in-house people are the memory; the outsourced team is the throughput.
Not inherently — it varies by vendor exactly as it varies by hire. What genuinely differs is context: an outsourced team knows your codebase but not the three years of decisions behind it. Documentation and code review close most of that gap.
Whatever your contract required. Make documentation, architecture records and a handover session contractual deliverables rather than good intentions, and the risk is manageable.
Yes, and it is often the best sequence — outsource to keep moving while you recruit, then transition with an overlap period. It removes the pressure to make a rushed hire.
When the roadmap has been continuously full for a year, when you have someone who can manage engineers, and when the total outsourced spend approaches loaded salary for the same capacity.

Comparison
A 30-minute call, then a written proposal with scope, price and timeline within two to three working days. No retainer required to get a real number, and no obligation if the answer is that we are not the right fit.
