Monthly iteration
New features, improvements and experiments shipped in regular releases from a prioritised backlog. Each cycle starts with an agreed plan and ends with a written summary and working software.

Product engineering
for the months after launch.
Most of a product’s life happens after the first release. BBR works as a continuing engineering partner: a small senior team on a monthly plan that ships improvements, keeps the product healthy, and can take over an existing codebase or work beside your own engineers, without you having to recruit and manage a department.
What the partnership coversA standing team,
A standing team,
without the hiring project.
Product engineering is continuing development of a live product by the same people month after month. You get design and engineering capacity that knows your codebase and your users, working from a roadmap you control.
Codebase takeover
When the original developer has left or the previous agency relationship has ended: an audit, recovery of access and build processes, stabilisation, then a normal delivery rhythm.
Maintenance and reliability
Dependency and security updates, OS and store-policy changes for mobile apps, monitoring, backups, bug fixes and performance work. The unglamorous tasks that keep a product sellable.
Roadmap and technical direction
Estimates before you commit to a feature, options with trade-offs, technical-debt decisions explained in business terms, and architecture guidance when the product outgrows its first design.
Who this is for
Companies with a product and no spare engineers.
- Startups after their first release that have users and feedback, need to keep shipping, and are not ready to hire a full in-house team.
- Founders who have lost their developer. A freelancer has moved on, an agency relationship has ended, or a technical co-founder has left, and the product still has customers.
- Small in-house teams with a roadmap larger than their capacity, who want a partner to own one area or absorb a period of heavy work.
- Businesses whose product is mature and mostly needs dependable maintenance with occasional features.
How this differs from our project work
| MVP development | Custom software | Product engineering | |
|---|---|---|---|
| Goal | First release of a new product | A system for your own operations | Continuous improvement of a live product |
| Scope | Fixed and written down | Fixed per project or phase | Rolling backlog, re-prioritised monthly |
| Commercial model | Fixed price, milestone payments | Fixed price per phase | Monthly capacity |
| Ends when | The product launches | The system is in use | You move it in-house or no longer need it |
Many clients move from the first column to the third: a fixed-price first release, then a monthly plan once real users start generating real priorities.
The processUnderstand it.
Understand it.
Steady it.
Then ship.
For a product we did not build, the first weeks are about earning the right to change it safely. For one we did build, the first two steps are already done.
How we work in detail ↗Audit and onboarding · 1–3 weeks
We review the repository, architecture, dependencies, infrastructure, deployment process and open issues, and get the product running locally and on staging. Output: a written assessment with risks ranked by severity and a proposed first-quarter plan.
Stabilisation · 2–6 weeks, where needed
Access and credentials moved into your company’s accounts, repeatable builds and deployments, error tracking, backups with a tested restore, critical dependency updates and the most damaging bugs. Healthy codebases skip most of this.
Monthly delivery cycle · ongoing
Plan agreed at the start of the cycle, work delivered to staging continuously, releases when ready, a demo and written summary at the end. A share of every cycle is reserved for maintenance so that debt does not pile up unseen.
Quarterly review
A step back from the backlog: what moved the product’s numbers, where the architecture is straining, whether the monthly capacity is right, and what the next quarter should aim for.
Handover, whenever you choose
If you hire in-house engineers, we help with the transition: documentation, walkthroughs, and a period of overlap. We can also assist with technical interviews for your first hires.
Technology approach
Your stack first. Rewrites last.
With a live product the technology is already chosen, and the default answer to “should we rewrite it?” is no. We work within the existing stack where we are competent in it, improve it incrementally, and recommend replacing a component only when we can show that keeping it costs more.
| Area | Where we work confidently | Notes |
|---|---|---|
| Web front end | React, Next.js, TypeScript, Tailwind | Including incremental migration from older JavaScript front ends |
| Backend | Node.js, PostgreSQL, REST APIs | Background jobs, webhooks, third-party integrations |
| Mobile | React Native (Expo), Capacitor | Store releases, OS updates, in-app purchases, push, ads |
| Managed platforms | Firebase, Supabase | Including products that have outgrown a first no-code or low-code build |
| Payments | Stripe-style subscription billing, store billing | |
| Infrastructure | Docker, cloud and VPS deployment, CI/CD | Always in accounts you own |
| AI features | Hosted language model integration | See AI development |
Outside our stack. We do not maintain Flutter apps, fully native Swift or Kotlin codebases, or Python machine-learning systems. If your product is built on those, a team that specialises in them will serve you better, and we would rather say that in the first call than in the third month.
Pricing factors
What sets the monthly cost.
An ongoing engagement is priced as monthly capacity, not per feature. The size of that capacity depends on:
- Pace of the roadmap. Maintenance with occasional small features needs a fraction of the capacity that a startup shipping weekly does.
- Breadth of the product. A web app alone, or web plus iOS plus Android plus an admin system. Each surface needs upkeep even when no features are added.
- State of the codebase. A tested, documented product absorbs change cheaply. One with no tests and manual deployments makes every change slower until that is fixed.
- Design involvement. Whether new features need interface design from us or arrive designed.
- Response expectations. Business-hours support on a best-effort basis costs less than agreed response times for production incidents.
- Who else is on the team. Working beside in-house engineers changes the split of product management, review and QA work.
The initial audit is a small fixed-price piece of work, and you keep the written assessment whether or not you continue with us. For a sense of baseline upkeep costs for a live app, see our guide to app maintenance costs. For a well-defined larger feature, we can still quote a fixed price inside an ongoing relationship.
Common mistakes
Where products stall after launch.
Spending the whole budget on version one
The first release tells you what users actually do. If no money remains to act on that, the launch was the end of the project, not the start of the product.
Treating maintenance as optional
Dependencies age, operating systems change, app stores raise their requirements and certificates expire. Skipped maintenance does not disappear; it arrives later as an emergency, usually at a bad moment.
Rewriting because the code is unfamiliar
Every new team is tempted to start again. A rewrite freezes features for months and reintroduces bugs that were fixed years ago. Most inherited codebases can be improved in place, one module at a time, while the product keeps shipping.
One person holds all the knowledge
If a single freelancer controls the repository, the hosting account and the store listing, the business is one resignation from a crisis. Accounts belong to the company, and the deployment process belongs in a document.
Changing teams every few months
Each switch costs weeks of re-learning. When comparing partners, weigh continuity and communication as heavily as rate. Our list of questions to ask a development agency includes the ones that reveal how a team handles long-running work.
A backlog with no owner
An outside team can estimate, advise and build. It cannot decide what your business needs most. Someone on your side has to own priorities and be available to answer questions, or the month gets spent on the wrong things.
FitWhen BBR is the right partner,
Good fit Not a fit
When BBR is the right partner,
and when it is not.
We are a small, senior, independent studio. For a long-running engagement that means the people who learn your product are the people who stay on it, and it also sets a ceiling on how much we can take on.
We are likely a strong match if
- You have a live product, or one close to launch, and need steady development capacity
- The stack is JavaScript or TypeScript based: React, Next.js, Node.js, React Native or Capacitor
- You want continuity from the same small team over many months
- Someone on your side can own priorities and answer questions each week
- You want all code, infrastructure and accounts in your company’s name
We will probably point you elsewhere if
- You need individual contractors placed under your own management (staff augmentation)
- You need ten or more engineers, or round-the-clock on-call coverage
- The codebase is Flutter, native Swift or Kotlin, .NET, Java or Python ML
- You need someone on-site
- You have one small fix and no ongoing need; a freelancer is more economical for that
Why use a partner instead of hiring
A team is more than a developer.
Keeping a product moving needs backend, front-end or mobile, design, QA and release skills, but rarely a full-time person in each. A single in-house hire covers one of those well, takes months to recruit, and leaves you exposed when they are on holiday or move on. A studio on a monthly plan gives you the spread of skills in the proportion you actually use, with continuity that does not depend on one individual.
The balance shifts as a company grows. Once the product is the core of the business and the roadmap can keep several engineers busy indefinitely, building an in-house team is usually right, and many companies run a hybrid for a while: internal engineers own the core, a partner owns a defined area. We go through the decision in in-house vs outsourced software development, and the hiring route in how to hire developers for a startup.
BBR maintains its own published products on Google Play, so store-policy changes, SDK updates, billing and advertising integrations, and live user feedback are part of our regular work. The Live Gold & Silver Prices and Grow.io case studies describe those products and the decisions behind them.
QuestionsFrequently asked
Frequently asked
questions.
How is this different from MVP development or custom software development?
MVP development is a fixed-scope project to reach a first release. Custom software development is project work on systems that run a business’s own operations. Product engineering is the continuing relationship after a product is live: a monthly capacity, a prioritised backlog, regular releases and maintenance, with priorities that change as you learn.
Can you take over a product another team or freelancer built?
Yes. We begin with a paid audit of the code, infrastructure, dependencies and deployment process, and give you a written assessment: what is sound, what is risky, and what we would fix first. We then stabilise access, builds and deployments before taking on feature work. Occasionally the honest finding is that part of the system should be rebuilt, and we explain why with evidence.
What is the minimum commitment?
Ongoing work is planned in monthly cycles, and notice periods are set in the contract. Continuity matters more than contract length: a team that holds the context of your product is far more productive than one that re-learns it every few months. We agree the monthly capacity with you and review it as needs change.
How are priorities set each month?
You own the roadmap and the priorities. We keep a shared backlog with estimates, propose a plan for each cycle that balances features, fixes and maintenance, and you approve it. At the end of the cycle you get a written summary of what shipped, what did not and why.
Can you work alongside our in-house developers?
Yes. We join your repository, your pull-request review process, your issue tracker and your communication channels. Typical arrangements are taking ownership of one area, such as the mobile app or integrations, or adding capacity for a period of heavy roadmap work. Clear ownership boundaries make this work well.
Who owns the code, and what happens if we stop?
You own the code and deliverables under the contract, and the repository, infrastructure and third-party accounts are in your company’s name throughout. If you move the work in-house or to another team, we hand over with documentation and a transition period. There is no proprietary framework or hosting that ties the product to us. See how we work.
How do time zones work with a team in Istanbul?
Istanbul is UTC+3 all year. That gives an overlap of most of the working day with the UK and Europe, a few hours with the US East Coast morning, and a shorter window with the Australian late afternoon. We agree fixed meeting windows and rely on written updates between them. The country pages for the US, UK, Canada and Australia go into the practical details.
