Enterprise Engagements · $50K-$300K
Custom iOS + Android. Matching web. Optional paid launch.
For companies that need a real mobile product, not a wrapper around their website. One senior-led team builds the app, the marketing site, and (optionally) runs paid acquisition for the first 90 days. Chase is on every call.
NDA on request · Engagements start with discovery, not a contract · You own every line of code we write
Three tiers. Transparent ranges.
Final price depends on scope, not how the call goes. We quote a fixed range after discovery so you can compare us against any other vendor on equal footing.

Why teams pick us over a $1M dev shop
We are not for every team. We are for teams that want senior accountability, modern stack, and one bundled engagement instead of three separate vendors.
One team, one accountability surface
Most enterprise builds need a dev shop, a marketing agency, and a media buyer. We do all three. One contract, one weekly call, one person to talk to when something breaks.
Senior-engineer led
Chase is the named senior engineer on every enterprise build. No bait-and-switch where the salesperson sells you Chase and a junior dev writes the code.
You own the code
Every line ships to your repo. Every credential lives on your accounts. We do not hold your business hostage. You can fire us at any phase boundary and still own everything.
Modern stack, no legacy
Swift / Kotlin / React Native on the front, Next.js + Supabase + edge compute on the back, AI baked in where it earns its keep. Nothing here ages out in 18 months.
How a 12-week build actually goes
Every phase has a named milestone and a written sign-off. You know exactly where the work stands and what comes next.
Weeks 1-2
Discovery & architecture
Stakeholder interviews, technical scoping, user-flow mapping, and a written architecture doc you sign off on before we touch code.
Weeks 3-4
Design & prototype
High-fidelity designs in Figma, plus a clickable prototype. We do not build until you can hold the experience in your hands.
Weeks 5-10
Build sprint
Two-week sprints with public progress demos every Friday. You see exactly what you are paying for, every week.
Weeks 11-12
Beta & QA
TestFlight + Play internal testing with your team. Crash logging, performance budgets, and security review before the app stores ever see it.
Weeks 13+
Launch & 90-day support
Coordinated submission to App Store and Google Play, web launch, optional paid media kickoff, and 90 days of bug fixes and tuning at no extra charge.
Modern stack. No legacy.
We pick boring, well-supported tools that will still be maintained in 5 years, not whatever is trending on Hacker News this month.

Honest answers to the expensive questions
How is this different from hiring an offshore dev shop?+
You get a senior US-based engineer on every line of code, not a junior offshore team supervised by an account manager. The trade-off is honest: we are not the cheapest. We are the team you hire when "shipping the wrong thing" costs more than the build.
How do you compare to WillowTree, Fueled, or Designli?+
Those teams are excellent and have bigger rosters, fancier client lists, and brand recognition. They also charge $300K-$1M for similar scope and require you to coordinate separately with marketing and media partners. We bundle the whole thing for $50K-$300K and Chase is on every call.
Why not just hire a senior engineer in-house?+
A fully-loaded senior mobile engineer in the US is $200K+/year. $50K with us buys 4 months of focused output plus a designer plus a backend plus a marketing site. After year one, if it makes sense, hire them. We will hand off the codebase clean.
What does the advertising layer actually include?+
Strategy, creative production, ad account setup, daily spend management on Meta / TikTok / Google for 90 days, conversion tracking, A/B testing on landing pages, and weekly performance reviews. Ad spend itself is your budget, separate from the engagement fee.
Can you start with just the app and add the web/advertising later?+
Yes. Each tier is a clean phase boundary. You can ship Mobile App Build, see how it performs, then upgrade to App + Matching Web or App + Web + Advertising as a follow-on engagement.
How do you protect my deposit?+
Phase 1 deposit is held against signed deliverables. Each phase has named milestones and a written sign-off. If we miss a milestone, you get the deposit back per the milestone guarantee. The full terms are on the Refund Policy page.
Inside Mobile
Apps your team actually uses
iOS and Android, native or cross-platform, shipped to both stores.
| Capability | What it does for your business |
|---|---|
Ship to App Store | We handle Apple review, signing, and submission so your iPhone and iPad app goes live without the fight. |
Ship to Play Store | We package, sign, and submit your Android build so you reach the other half of your market on day one. |
Push in real time | Send instant notifications to every device so customers act on offers and updates without you buying another ad. |
Work offline | Your app keeps working with no signal and syncs when it reconnects, so field teams never lose progress. |
Track every tap | In-app analytics show where people click, drop off, and convert, so you fix the leaks and grow what works. |
