Stateless is a Hong Kong-registered, founder-led mobile studio for teams that need senior mobile execution before a full-time app hire or large vendor bench makes sense. React Native by default, native modules when needed, weekly demos, and store-launch discipline.

No long sales process. You’ll get a direct read on scope, risk, timeline, and whether Stateless is a fit.

Get a direct mobile risk reply, usually within one business day: what to build, what to cut, and what could block launch.

WHICH PROBLEM ARE YOU SOLVING?

Start from the actual business blocker.

Stateless is easiest to buy when the engagement is tied to a launch outcome: keep delivery moving, unblock release, scope a V1, or give your agency a credible mobile delivery lane without hiring app staff.

Ship While You Hire

Hiring mobile talent?

Your roadmap may not wait for a 6–10 week hiring cycle. Stateless adds senior React Native / native mobile capacity, release support, code review, and handover while your full-time hire is still in progress.

From HK$48k/month · 2-month minimum

App Rescue Sprint

App blocked or hard to release?

For apps stuck in technical debt, release delays, App Store friction, unstable React Native builds, native module issues, or unclear architecture.

From HK$28k · 5–10 days

Store-Ready V1

Need a focused V1?

Scope, design what is needed, build, QA, and support submission for a tight mobile V1 without a bloated delivery process. Weekly demos and strict scope control.

WHAT YOU GET

Senior mobile execution,
without a large-agency process.

The useful parts are concrete: clear scope, playable progress, release blockers surfaced early, and a handover your team can actually use.

Scope that survives launch

We cut the V1 down to the core loop, document decisions, and keep the build aligned with timeline and budget.

React Native plus native depth

React Native is the default for speed. When platform APIs, background behavior, or store policies require native work, we flag it early.

Weekly playable demos

No black-box development. You see progress weekly and make decisions before risk compounds.

Store launch and handover

QA, release prep, App Store / Google Play support, repo handover, and a practical next-step backlog.

HOW IT WORKS

Risk. Scope.
Demo. Release.

This is the typical full V1 path. Rescue work is shorter, and any larger native or backend risk is surfaced before the build starts.

Risk & Scope

We identify the core loop, technical constraints, launch blockers, and what should be cut from V1.

Days 1–5

Design for buildability

Flows are designed around the business action and implementation reality, not decorative mockups.

Days 3–10 / Week 1–2

Build with weekly demos

Senior mobile execution, React Native / native modules as needed, and a playable build reviewed every week.

Weeks 2–6

Release & handover

QA, store submission support, production basics, repo handover, and a next-step backlog.

Final week / Weeks 6–8
FIT

Built for focused teams,
not vague app ideas.

The strongest engagements start with a real business pressure: hiring lag, release risk, a pilot window, or an agency client that needs mobile delivered properly.

Good fit

  • Product teams hiring mobile talent but needing delivery now.
  • Founders with a serious V1 deadline, funding conversation, pilot, or launch window.
  • Agencies that need mobile delivery under referral or white-label terms.
  • Teams with an app that is blocked, fragile, slow to release, or hard to maintain.

Not a fit

  • HK$10k app ideas.
  • Feature-heavy marketplace concepts with no budget or validation.
  • Enterprise RFPs that need a large vendor bench.
  • Teams that want to micromanage hourly output instead of owning a launch outcome.
  • Projects unwilling to cut scope.
PROOF

Proof: complex mobile constraints
shipped to store.

The public proof point is intentionally specific. RaiSecure shows the native edge cases, store-policy constraints, and weekly decision-making this studio is built for.

FAQ

The questions that decide deals.

Straight answers to reduce risk and remove ambiguity.

Who actually builds the app?
Stateless is founder-led. You work directly with Lucas, a senior mobile engineer. For larger scopes, pre-vetted independent specialists may support UX or QA with your approval, but the engagement remains senior-led and tightly controlled. No junior-heavy outsourcing model.
Are you based in Hong Kong?
Stateless is a Hong Kong-registered company operating in GMT+8. Delivery is remote-first. Hong Kong workshops or stakeholder meetings can be arranged by appointment when the project requires it.
What does a serious V1 cost?
Most serious V1 builds start around HK$128k and increase with integrations, native modules, backend complexity, compliance, and release constraints. If the scope is unclear, start with a V1 Scope Sprint.
Can you help if we are hiring a mobile developer?
Yes. The Ship While You Hire model gives you senior mobile capacity while your full-time hire is still in progress, then hands over cleanly when they join.
Can you rescue an existing app?
Yes, if there is access to the repo, release history, and enough context to identify blockers. The App Rescue Sprint is designed for this.
Do we own the code?
Yes. You own the code and assets produced for your project under contract. Stateless provides repo handover and documentation.
React Native vs native?
React Native is the default for speed. If platform APIs, background behavior, performance, or store policies require native Swift/Kotlin work, Stateless flags it early and scopes it explicitly.
What happens after launch?
You get release support, handover, and a V2 roadmap. Ongoing support can be scoped, but the first job is to launch a focused V1 or unblock the app without hiding future risk.
