Mobile engineering, outsourced
Flagship Mobile Engineering is the mobile team you don’t have to hire. We design, build and ship production iOS and Android apps — and the cloud backends behind them — and we prove your product strategy with real market data before a line of code is written.
Time to first release
Recruit, onboard, architect, build, stabilize.
Senior team on day one. Weekly builds you can install.
Typical build

The problem
01
Months of recruiting before a single line ships — and a team that’s hard to scale back down when the launch is done.
02
iOS, Android and the backend each want their own specialists, process and release train.
03
Legacy apps get rewritten alongside feature work, so the new version is always a quarter away.
04
Engineers who don’t listen ship the wrong thing — then you pay for the rework and lose another quarter.
Strategy validation with marketing science
Plenty of apps are built well — for the wrong thing. Before engineering starts, we test your product bet against the real market, so you walk into the build with evidence, not opinions.
Live ads and landing pages measure who actually clicks, signs up or pre-orders.
Clickable prototypes in front of your real users to find what confuses or sells.
A/B tests on positioning and pricing, so launch day isn’t your first experiment.
Build it, change it, or drop it — with the data behind the decision.
How it works
Step 1
We talk to your engineering lead about the product, the systems it touches and the deadline.
Step 2
Marketing science tests demand, messaging and the riskiest features with real users first.
Step 3
A written architecture, milestone plan and price — so you know scope and cost before work starts.
Step 4
Installable builds every week, demoed to your leaders and reviewed with your team. No black box, no surprises.
Step 5
We ship to the App Store and Google Play, document everything, and hand off — or stay on to run it.
What we build with
The math
| In-house team | Flagship Mobile Engineering | |
|---|---|---|
| Time to first release | 2–3 years for a full rebuild | A few months |
| Cost model | Salaries, recruiting, benefits, management overhead | Priced milestones, typically $200k–$500k |
| Who builds it | Whoever you can hire this year | Senior mobile engineers, start to finish |
| Where the team is | Wherever you can recruit | All in-house and US-based, in Utah — no overseas contractors |
| Platforms | Separate iOS and Android teams | Flutter or fully native — your call — plus the backend |
| Strategy validated first | Rarely — the roadmap is the bet | Marketing science proves demand before the build |
| Built to your intent | Depends on who you hired | Weekly demos to leadership; course-correct in days |
| Code ownership | Yours | Yours, in your repo from day one |
From the field
~$3M a year.
Three years.
That’s what we’ve watched one enterprise mobile rebuild cost at a billion-dollar company. A focused senior team could have shipped it in a few months, for well under half the spend. That gap is why we started this firm.
Recent work
Enterprise scale
Mobile engineering for a platform now valued at over a billion dollars.
Financial services
Mobile work held to the security and reliability bar of a global card network.
On-demand marketplaces
Several multi-sided apps: customers, drivers and businesses, real-time tracking, dispatch and payments.
We built three connected apps — one for the business, one for its technicians and one for its customers — plus the cloud backend behind them. Customer intake is now fully automated and nearly all client onboarding runs on its own, which let the business 10x its growth.

“We’d been quoted more than a year for our apps. Flagship built all three in two weeks. Intake and onboarding now run themselves, and it’s let us 10x our growth.”

Engagements
A new iOS + Android app and its backend, from architecture to the stores.
Replace a legacy or two-codebase app with one modern app — without freezing your roadmap.
Marketing science on its own: prove the product bet before you commit the engineering budget.
FAQ
Senior engineers who don’t need ramp-up, architecture patterns we’ve already proven at scale, and no recruiting or long-term headcount on your books. The savings hold whether we build in Flutter or fully native.
Before we build, we run small, fast experiments — live ads, landing pages, clickable prototypes and pricing tests — to show whether customers want what’s on the roadmap. You get the data and a clear recommendation before committing the engineering budget.
We write the plan back to you in plain language, demo working software to your leaders every week, and treat your feedback as the spec. Misunderstandings get caught in days, not at launch.
We start with your systems, auth and compliance needs, and write the architecture down before we build. Your team reviews every pull request.
Every engineer and employee is US-based and works in-house out of Utah. We don’t use overseas contractors — the work is done by our own team, start to finish.
You own the code and docs. We can hand off to your team, train them, or stay on for ongoing releases.
Both. Flutter when one shared codebase fits your product; pure native Swift and Kotlin when you need deep platform features, already have a native codebase, or that’s your team’s standard. Either way, about half the cost of building it in-house.
Thirty minutes with a senior engineer. Bring your roadmap — you’ll leave with an architecture sketch, a timeline and a price range.
