Build with us
like you'd build in-house.

Hire mobile app developers who join your team, your repo, and your standups — backed by a 180-engineer mobile app organization that ships across every mobile stack — and helps you pick the right one. Native iOS + Android for OS-level depth, Flutter for one codebase across platforms, RN for JS-team velocity, KMP for shared logic.

On your team, day 1

Engineers join your Slack, your Jira, your sprint board. No layers, no PM filter — they pair with your mobile app team like senior in-house hires.

Direct git access

They open PRs straight into your repo. You see every commit, every screen, every test, every release branch.

You manage the work

You set product priorities and sprint goals. We handle hiring, retention, payroll, benefits, upskilling, and laptops.

Hiring Process

From "we need a mobile app dev"
to onboarded — in 2 weeks.

4-step process pulled straight from how we work. 48 hours to first profile. 2 weeks to a mobile app developer joining your standup.

01
Day 1-2

Requirement Analysis

We begin by understanding your business goals, technical requirements, project scope, and timelines to ensure the right mobile app development approach for your team.

02

Start an Interview

Interview the selected mobile app developers to assess their technical expertise, communication skills, and project fit before final selection. Live coding, system-design — your call.

04
Day 11-14

Onboarding

Once approved, the developer is onboarded quickly and starts working as part of your team with complete transparency and regular updates. First PR by day 14.

FS
Founder, travel startup
"

They run our entire mobile engineering — 14 engineers across iOS, Android, Flutter. ASO + CI + analytics all in one pod. We don't have a single in-house mobile hire.

CO
COO, ride-hailing

★★★★★

Their mobile DevOps engineer set up our CI from scratch. Builds in 12 minutes, phased rollout templates, ASO weekly reports. Wish we'd hired him two years ago.

Frequently Asked Questions

Everything you need
to know before hiring.

What mobile stack should I use?
It depends on (1) team skills, (2) OS features needed, (3) time-to-market, (4) future support model. Native for OS-level depth (Live Activities, Wear OS); Flutter for one codebase across iOS+Android+Web; RN for JS-heavy teams; Capacitor for web-tech-only teams. We give you a written recommendation on the discovery call — free.
Can you run our entire mobile engineering, not just hire one dev?
Yes. Many of our clients have zero in-house mobile hires — we run product strategy, design, engineering, CI, ASO, analytics, and store releases. You bring product vision, we run the rest.
What does the 14-day SLA actually mean?
From discovery (day 1) to a mobile developer being onboarded and shipping their first TestFlight + Play Internal build by day 14.
How does the replacement guarantee work?
5 business days notice, 2-3 replacement profiles within 48 hours.
Do you handle ASO and store releases?
Yes. Keyword research, screenshot + preview video, listing copy, A/B tests on Play Console + App Store, phased rollout, response to negative reviews. Bundled with delivery pods or available standalone.
Can you ship to App Store + Play Store in 6 weeks?
For a focused MVP — yes. We've done it 18 times in the last 3 years. Realistic scope (1 happy path, 1 monetization model, 1 launch market), Flutter or RN front, Firebase/Supabase back. Larger apps take 12-20 weeks.
What about IP, NDAs, and source code?
100% source code authorization. App Store Connect + Play Console memberships transferred on request. Standard MSA assigns IP day 1.
How do you vet mobile developers?
5 steps: resume + App Store + Play portfolio screen, technical screen with our mobile tech director, live coding test (90 min) in the relevant stack, system-design round (60 min) on store release strategy + mobile architecture, culture-fit + references.
