Mobile App Development in Austin, TX
Austin is a founder town. The SaaS pipeline along MoPac, the venture money that followed Tesla and Oracle, the East Austin coffee shop full of pre-seed builders — they share one specific problem with mobile. They need a mobile client that ships alongside the MVP, scales with the product, and does not lock them into a vendor's UI kit the moment they hit Series A.
The problem with off-the-shelf mobile in Austin
Most pre-seed Austin founders get pushed into a mobile shop that wants $250,000 up front, or an offshore team that produces a codebase the in-house engineers cannot maintain. Senior-engineering, fixed-scope, full-source-handoff at a real pre-seed budget is rare. That is the gap we sit in.
A custom mobile build puts the data model, the UI, and the platform layer around how you actually operate. No vendor SDK tax. No per-seat ratchet. For Austin operators specifically, that means mobile shaped for SaaS startup MVP mobile — not a generic template.
What we ship for Austin companies
MVP-grade React Native client
What investors want to see in week one — clean code, real backend, no demoware.
Self-serve + sales-assisted hybrid
Product-led growth signals (sign-up, activation, expansion) fired from the mobile client into your CRM or sales tool.
Stripe Billing + usage-based pricing
Plan, seats, usage, and dunning state visible inside the mobile app — no exporting CSVs to figure out which user is on which plan.
Postgres-native event capture
Mobile analytics fire into your own Postgres, not a vendor SaaS — founder-readable dashboards on SQL views, not Amplitude seats.
Tech stack
Hosted on Vercel, AWS, or your own infrastructure. PostgreSQL is the source of truth; the mobile client defers to it.
Reference builds
J5 Sales OS is our reference SaaS-founder build — a sales operations platform with contact deduplication, outreach presets, dual-mode lead flow, and embedded reporting whose mobile surface lets AEs work pipeline from the road. We dogfooded the platform on our own sales motion before shipping the pattern. Same architecture works for an Austin pre-seed building a CRM-first mobile MVP or a Series-A SaaS shifting from a SaaS mobile vendor to in-house.
Reference work: J5 Sales OS, Northcrest Fence, and Bridgepointe Painting.
How we work remote from Georgia
QUANT LAB USA is founder-led from Macon, Georgia. William Beltz runs every engagement from kickoff through handoff — no agency middleman, no offshore handoff at the framework boundary. Discovery happens over a structured video session; weekly demos run on the same cadence; staging is live from week two so you can put a real mobile build in your team's hands before final delivery.
For Austin clients, that means full Eastern-time overlap, fixed-scope contracting against milestones, and on-site work when the engagement warrants it. Book a scope call to walk through your workflow and get a written estimate.
Pricing for Austin mobile builds
Austin mobile engagements typically scope between $35,000 and $95,000 for a production-grade MVP with backend, sized to actual runway. Fixed-fee per phase, milestone-based delivery.
We quote fixed-fee scope after a 30-minute discovery call. Engagements include the mobile client, the backend, the API surface, Stripe and payments wiring as scoped, and App Store and Play Console submission. Source-code handoff is included at delivery — no platform fees, no per-seat charges, no vendor lock-in. See our parent mobile service page for the broader engagement model.

Austin mobile FAQ
Will you work with pre-seed Austin founders?
Yes — most of our SaaS mobile engagements are pre-seed through Series A. We size the build to your actual runway, not a notional enterprise price.
Can the mobile client grow into a product-led growth motion?
Yes. We model self-serve signups, activation events, and expansion signals alongside the traditional pipeline from day one — no rip-and-replace at scale.
Do you have East Coast or Central time overlap?
Georgia HQ — full ET overlap, which lines up cleanly with Austin's CT working hours. Most calls land 9-3 CT.
Will the app survive a Series A code review?
Yes. Senior-engineering, TypeScript everywhere, audit trails, and clean module boundaries. Your future CTO can grep it without wincing.
iOS first or Android first?
Depends on your buyer. Most Austin SaaS pre-seeds default to iOS for ICP fit; we are equally comfortable shipping Android first when the market demands it.
Who owns the source code?
You do. Full repository handoff at delivery — no vendor lock-in.
