Mobile App Development
for Bay Area Startups

Appverra is a mobile app development company that builds iOS and Android apps for San Francisco startups, SaaS companies, and funded founders across the Bay Area. We have shipped 150+ apps for 700+ customers. Our apps have millions of downloads collectively. Bay Area startups move fast and expect production-quality code — not agency theater. Three co-founders write your code. Flutter, React Native, Swift, Kotlin. Fixed-bid pricing from $7,997. MVPs ship in 6 weeks.

Why SF Founders
Hire Appverra

San Francisco and the Bay Area remain the global epicenter of venture-backed startups. The region raised over $60 billion in VC funding in 2025. But Bay Area engineering talent costs $180K-$300K per engineer, and local agencies charge $250-$400/hour. Early-stage founders face a math problem: they need production apps but cannot afford SF-rate engineering teams until Series A. That is where we fit.

Silicon Valley Quality, Fixed-Bid Price

SF agencies charge $250-$400/hour. A typical MVP costs $150K-$350K. We charge fixed-bid: $14,997 for Launch tier. Same Flutter, same Swift, same Kotlin. The difference is three founders instead of 50 employees with a SoMa office lease.

Ship Before Your Next Board Meeting

You have 18 months of runway. Your board wants to see product-market fit signals, not wireframes. We ship MVPs in 6 weeks — real apps in the App Store with real users before your next quarterly update.

Code Your CTO Will Inherit

Bay Area founders hire a CTO at Series A. That CTO will inherit our codebase. We write clean, documented, testable code in mainstream frameworks (Flutter, React Native, Swift, Kotlin) with deep talent pools. No proprietary frameworks. No vendor lock-in.

Built for SaaS Mobile Companions

Your web SaaS is growing. Users are asking for a mobile app. We build the companion — synced state, push notifications, offline mode, biometric auth — without touching your existing backend. Your API stays yours.

AI-Ready Architecture

Bay Area startups are AI-first. We build mobile apps with AI integration — Claude/GPT API endpoints, on-device inference via Core ML / TensorFlow Lite, recommendation engines, and natural language interfaces. The mobile layer for your AI backend.

Same-Day Timezone Overlap

We are Eastern Time. Full overlap with Pacific from 9 AM - 6 PM ET. No overnight waits. Daily async updates. Weekly video syncs. For critical milestones — demo day, investor pitch, launch — we fly to SF.

What We Build for
Bay Area Startups

SaaS Companion Apps

Your B2B SaaS works on desktop. Your users want mobile access. We build the companion app — real-time sync, push notifications, offline support, biometric login — that turns desktop users into all-day users.

Fintech and Payments

Payment apps, neobanking, investment platforms, peer-to-peer transfers, expense tracking. Stripe, Plaid, Apple Pay integration. PCI-DSS compliant architecture. We have shipped fintech apps processing real money.

Marketplace Platforms

Two-sided platforms with matching, real-time tracking, messaging, payments, and reviews. We built a live US ride-booking marketplace running in production today. Uber-for-X models are our specialty.

AI-Powered Apps

Natural language interfaces, recommendation engines, predictive analytics, computer vision, conversational AI. We build the mobile frontend for AI backends — Claude/GPT integration, Core ML inference, real-time AI features.

Developer Tools (Mobile)

Mobile dashboards for devtools, monitoring apps, admin panels, internal tooling. If your SF startup builds infrastructure, we build the mobile interface your customers access it through.

Prototype → Production

You built a prototype with Cursor, Bolt, or V0. It works. Investors liked the demo. Now you need production code — scalable, tested, App Store ready. We take your prototype and ship the real thing in 6 weeks.

SF Cost
Comparison

Option Cost for MVP Timeline Risk
Hire SF engineer ($220K/yr) $110K+ (6-mo salary + equity) 4-6 months Single point of failure
SF agency ($250-$400/hr) $150K-$350K 3-6 months Scope creep, hourly overruns
Offshore team ($30-$55/hr) $20K-$50K 3-5 months Timezone gap, quality variance
Appverra (fixed-bid) $14,997 6-8 weeks Fixed price, no overruns

Bay Area FAQ

Are you based in San Francisco?

Our headquarters is in New York City. We serve Bay Area clients with full-day timezone overlap — 9 AM to 6 PM ET covers your entire Pacific workday. For YC demo day, investor pitches, or launch events we fly to SF.

We built a prototype with Cursor/Bolt. Can you take it to production?

Yes — this is increasingly common with Bay Area founders. You validated the idea with an AI-generated prototype. Now you need production code that scales, handles edge cases, passes App Store review, and is maintainable by your future CTO. We take your prototype, extract the core logic, and rebuild it in Flutter or native in 6 weeks.

Can you integrate with our AI backend?

Yes. We build mobile frontends for AI backends regularly — Claude/GPT API integration, streaming responses, Core ML on-device inference, real-time AI features. If you have a working API, we build the mobile interface. If you need the full stack, we build that too.

We need a mobile companion for our web SaaS. How does that work?

We consume your existing API. No backend changes required. The mobile app syncs state, renders your data natively, adds push notifications and offline access, and handles platform-specific features (biometrics, camera, location). Timeline: 6-8 weeks for most SaaS companions.

What if we want to hire our own engineers later?

That is the plan. Most Bay Area startups hire engineering at Series A. We write code specifically for handoff — mainstream frameworks, clear documentation, comprehensive tests. When your CTO joins, they inherit a codebase they can read and extend, not a vendor dependency.
