Studio vs in-house developers: the true cost of building your own team

Build an in-house team when software is the core of your business, the roadmap is continuous, and you have someone able to hire and lead engineers. Use a studio when you need to ship sooner than you can hire, need skills you cannot justify full-time, or want to prove the product before committing to permanent salaries. Many companies end up doing both, in that order: a studio builds and launches the first version, then hands it to the team you hire once there is a real product to own.

The decision is often made on salary alone, which understates the cost of employing people and ignores the time it takes to hire them. This guide sets out the full picture for founders, CTOs and operations leaders: what an in-house team really involves, how long hiring takes, what employment costs beyond salary, why retention and management matter as much as recruitment, and when each option is genuinely the better choice.

What ‘an in-house team’ actually means

One developer is not a team. A product that real customers depend on needs a range of skills, and a single hire rarely covers them all well. A minimum viable product team usually needs, at least part-time:

• Technical leadership: someone who makes architecture decisions, reviews code and sets standards. Without this, every other hire is harder to manage and assess.
• Product and design: someone who turns business goals into a prioritised backlog, and someone who designs the user experience and interface.
• Frontend and backend engineering: for web or mobile interfaces, APIs, data and integrations. For iOS and Android apps, add mobile skills.
• Quality: test automation and release checks, often shared across engineers but owned by someone.
• Infrastructure and operations: hosting, deployment pipelines, monitoring, backups and security. Often part of a senior engineer's role in small teams, but it has to be someone's job.
• Cover: holidays, illness and departures mean a team of one or two has gaps. Someone has to be able to fix production while the usual person is away.

This is why the honest comparison is rarely ‘one developer’s salary versus a studio’. It is ‘the smallest team that can build, run and evolve this product safely’ versus a studio that already has those roles.

Time to hire: longer than the job advert suggests

Recruitment takes time even when it goes well. SHRM's most recent recruiting benchmarking, drawn from more than 4,600 organisations, puts the median time to fill a nonexecutive position at 39 calendar days. That is the general market across roles; senior and specialised engineering roles can take longer, and the clock usually stops at acceptance, not at the first day of work.

Add the stages that sit outside that number:

1. Defining the role. Writing a credible job description for a product that does not exist yet is hard, and getting it wrong attracts the wrong candidates.
2. Notice periods. Experienced engineers are usually employed. Their notice period can add weeks or months before they start, depending on the country and contract.
3. Onboarding. New hires need time to learn your domain, tools and codebase before they work at full speed. If there is no codebase yet, they need time to set one up.
4. Building the rest of the team. Each additional role repeats the cycle, and the first hire often needs to be involved in interviewing the next.
5. Failed hires. A hire that does not work out restarts the process, and the cost of discovering it is months of reduced progress.

A studio is not instant either: there is usually a scoping phase and a start date that depends on its capacity. But it can typically begin delivery within weeks, with the full set of roles in place from the start.

The true cost of an employee

Salary is the largest cost of an employee but far from the only one. The US Bureau of Labor Statistics' Employer Costs for Employee Compensation for June 2026 shows benefits making up 30.0% of total compensation costs for private industry workers, with wages and salaries the other 70.0%. In the UK, employers pay Class 1 National Insurance at 15% on earnings above £5,000 a year for most employees, according to HMRC's rates for 2026 to 2027, on top of pension contributions and any benefits. Other countries have their own payroll taxes, social contributions and statutory benefits.

Then come the costs that do not appear on a payslip:

• Recruitment: agency fees, job board listings, assessment tools and, above all, the hours your team spends reviewing applications and interviewing.
• Equipment and software: laptops, licences, development tools, cloud accounts for development and testing, security tooling.
• Workspace and travel: office space or remote-work stipends, plus travel for team gatherings.
• Learning: courses, conferences and the time to attend them, which strong engineers expect.
• Management: a manager's time for one-to-ones, planning, performance reviews and career development. If the manager is a founder, that time comes out of running the company.
• Idle and ramp-up time: weeks of onboarding at reduced output, and periods where the roadmap has less work than the team has capacity.
• Exit costs: notice, statutory obligations and the knowledge that leaves with the person.

None of this means in-house is expensive in absolute terms; for a company with a long, continuous roadmap it is often the most cost-effective option over several years. It means you should compare a studio's price against the fully loaded cost of the team you would need, over the same period, rather than against a salary.

Retention: the cost that arrives later

Hiring is only the start. Engineers move between jobs, and the Stack Overflow 2025 Developer Survey found that 45.6% of respondents were not looking for a new role, while 28.8% were somewhat considering a move and 14.8% were strongly considering one. Gallup estimated in 2019 that the cost of replacing an individual employee can range from one-half to two times the employee's annual salary.

For a small team, the bigger risk is concentration. If one person built most of the system and leaves, the knowledge leaves too. Documentation, code review, tests and shared ownership reduce that risk, and they are worth insisting on whether your engineers are employees or a studio's team.

Salary is the price of an engineer. The cost of a team is salary plus the time it takes to find, onboard, manage and keep the people, and the work that stops when one of them leaves.

Management: the question that decides most cases

Who will lead the engineers? This is the question that matters most, and it is often skipped. A non-technical founder hiring a first developer faces three problems at once: judging technical candidates, setting architecture direction and managing technical work day to day. Without someone who can do those things, the first hire carries the whole technical strategy alone, often before they have the experience to do it.

If you have a strong technical co-founder or CTO, in-house becomes much more attractive, because the hardest role is already filled. If you do not, your options are to hire a senior technical leader first (the hardest and slowest hire to make), to engage a fractional CTO or adviser, or to work with a studio that brings technical leadership with it while you learn what the product needs.

Three situations, three answers

Studio vs in-house team side by side

When an in-house team is the better choice

There are strong reasons to build your own team, and a studio that pretends otherwise is not serving you. In-house wins when:

• Software is the product. If your company's value is the software itself, the knowledge of how it works is a core asset and belongs inside the company.
• The roadmap is continuous. A steady flow of work for years keeps a team fully used and lets it build deep domain expertise.
• You can lead engineers. A capable technical leader is already in place or is your first hire.
• Speed of iteration matters daily. Engineers who sit with customers, sales and support can ship small improvements continuously without any contract in between.
• Confidentiality is extreme. Some work, for regulatory or competitive reasons, is better kept within employees under direct control.
• You can afford the time. If there is no pressing launch date, hiring carefully is better than hiring fast.

When a studio is the better choice

• You need to launch before you can hire. A funding round, a pilot customer or a market window will not wait for recruitment.
• The product is not yet proven. Committing to permanent salaries before you know what customers want is a large bet. A studio lets you learn first.
• You need skills for a phase, not forever. Mobile, AI features, a security review, a cloud migration or a redesign may need specialists for months, not years.
• You lack technical leadership. A studio brings architecture, review and delivery management while you decide who to hire.
• Your workload is uneven. Bursts of work followed by quieter periods suit a variable cost better than a fixed one.
• You want a clean starting point for a future team. A well-documented, tested product on a mainstream stack is a much easier place for a first hire to start than a blank page.

The hybrid path that keeps both options open

For many companies the best answer is a sequence. A typical pattern looks like this, in weeks and team shape rather than money:

1. Scope the first version. A short discovery phase defines what must be in the first release and what can wait. Our guide to scoping an MVP covers how.
2. A studio builds and launches it. A small senior team builds in repositories and cloud accounts you own, with regular demos so you see progress and learn the product.
3. Learn from real users. With the product live, you discover which skills you actually need in-house: perhaps a product-minded full-stack engineer, perhaps a mobile specialist.
4. Hire against real requirements. The job description is now concrete, candidates can see the codebase, and the first hire has a working system rather than a blank page.
5. Overlap and hand over. The studio works alongside your new engineer for a period, pairing on changes and transferring knowledge, then steps back to support or leaves entirely.

This only works if the handover is designed in from the start. Ask any studio to show you what it hands over on a past project, and insist on the essentials:

• Architecture and data model documentation that a new engineer can read in a day.
• Automated tests that run on every change, and a deployment pipeline with a staging environment and rollback.
• Monitoring, alerting and a short runbook for common incidents.
• Every account, domain, credential and secret already in your name.
• A mainstream technology stack that is easy to hire for in your market.
• A record of significant decisions and the reasons behind them.

Our guide to software maintenance and support covers what keeping a product healthy after launch involves, whoever does it.

A worked example in weeks and team shape

Consider a company that wants a customer portal with a web app, an iOS and Android app and an admin dashboard, connected to its existing billing system. Assume the build needs roughly the same engineering effort whoever does it: a product designer, two or three engineers covering web, mobile and backend, and a senior lead, for a few months.

Route one: hire first. The company recruits a lead engineer, which takes several weeks to fill plus a notice period. The lead then helps hire a mobile engineer and a backend engineer, each with their own recruitment cycle and notice. Design is contracted separately. Real building starts once enough of the team is in place, and the first months include setting up tooling, pipelines and conventions. The team is fully owned and will carry deep knowledge forward, but the first release lands months later than the build effort alone would suggest, and the company pays salaries throughout recruitment and ramp-up.

Route two: studio first. After a short scoping phase, a studio team with the same shape starts in the company's own accounts, with design, engineering and quality working together from the first week. The first release lands after roughly the build effort. Meanwhile the company recruits one product-minded engineer against a live system, who joins before launch, pairs with the studio and takes over day-to-day ownership. Further hires follow when the roadmap justifies them.

Neither route is right for everyone. Route one makes sense when timing is flexible and the company is sure of a long roadmap. Route two makes sense when the launch date matters or the roles are still unclear. The useful exercise is to draw both timelines for your own situation, week by week, before choosing.

Hidden costs on both sides

Estimate each of these in hours for your situation and add them to the obvious costs. Our cost calculator can help size the build itself, which is the same work whoever does it.

Questions to ask before you decide

Questions for yourself

• Is there enough work to keep a full team busy for the next two years, or is this a launch followed by occasional changes?
• Who will interview, lead and develop engineers? Do they have the time and experience?
• What date does the first version need to be live, and can recruitment realistically meet it?
• Which skills does the product need permanently, and which only for a phase?
• What happens to the product if your one or two engineers leave?

Questions for a studio

• Who exactly will work on the project, and will I speak to them directly?
• Will the code, hosting and accounts be in my name from the first day?
• Can you show me a handover pack from a previous project?
• How would you work alongside an in-house engineer if we hire one during the project?
• Which technologies do you use, and how easy is it to hire for them in my market?
• What do support and evolution look like after launch, and can we stop at any time?

How Authect approaches this

Authect is a founder-led software development studio. You talk to the founders who develop your project, never a salesperson or account manager, and every project is led by a senior engineer. Teams are small, and we use AI to accelerate delivery with an engineer reviewing every line. Conversations start online, and we meet in person later in a project where it helps.

We build web and desktop SaaS platforms and iOS and Android apps, and cover what comes after launch through fixed-price projects, monthly sprints, and support and evolution. Clients own the code, infrastructure and designs from day one, which is what makes hiring your own team later straightforward: nothing has to be transferred because it was always yours. We are happy to build a first version and then help your first engineer take over, or to work alongside a team you already have. Read what founder-led delivery changes, or tell us where you are.
