RapidDev builds custom mobile and web apps in Miami, typically shipping a production MVP in 6–12 weeks for a fixed $13,000–$25,000. That is a fraction of the cost of hiring an in-house team in South Florida (roughly $430,000 a year for two engineers) or commissioning a Miami agency ($120,000–$400,000 per build). One team ships the iOS app, the Android app, and the web app on shared infrastructure, and the founder owns all of the code.
One team for your iOS, Android, and web build. We help Miami founders go from Figma or a Lovable prototype to a production app your users — and your investors — actually trust, whether you're serving the US or scaling into Latin America.
Miami is the fastest-maturing tech ecosystem in the country, and it doesn't play by Silicon Valley's rules. The metro pulled in more than $2 billion of venture capital in the first half of 2025 alone — one of its strongest years on record — and Startup Genome now ranks it among the top ten US ecosystems and 22nd in the world. Fintech and crypto dominate deal flow, but proptech, health tech, and logistics are all real categories here. The thing no other US city can copy is geography: Miami is the commercial gateway between North American capital and Latin American markets, and roughly two-thirds of funded Miami startups already sell across borders. We build for that reality — payments that clear in multiple countries, apps that pass a fintech security review, and the polish that survives a raise.
Miami is the single busiest bridge between US capital and Latin American markets, and around 65% of funded local startups already report international customers. If your app needs multi-currency payments, Spanish and Portuguese support, or cross-border compliance, that has to be architected in from the start — not bolted on later. We've built exactly this kind of border-spanning product.
Fintech is South Florida's most-funded sector by a wide margin, and it drags the whole ecosystem's security expectations up with it. A wallet or payments app that can't pass a security review is dead on arrival with Miami investors. We build with real row-level security, Stripe done correctly, and an architecture that survives technical diligence.
eMerge Americas draws 20,000+ attendees from 60 countries and functions as the connective tissue between Miami founders, investors, and global partners — with dedicated hubs for health tech, fintech, and AI. Launching around that calendar means your product has to be demo-ready on a hard date, and we build backward from deadlines like it.
Miami's engineering bench is growing fast but is still thinner than SF or New York, and senior mobile talent is in real demand. Hiring two strong engineers can take months and cost north of $400K loaded in year one. Bringing us in lets you ship your v1 now and hire deliberately later, from a position of traction rather than urgency.
South Florida by the numbers
Who we build for in South Florida
Payments, neobanking, and cross-border money apps — the single most-funded sector in Miami — that need Stripe, real compliance, and LatAm rails from day one.
Wallets, on-chain dashboards, and exchange apps for the city that rebranded itself around crypto — with the wallet UX and security users expect.
Real-estate, short-term-rental, and property-management apps for a market where proptech is one of the busiest funding categories in South Florida.
HIPAA-aware patient and provider apps for Miami's fast-growing medtech corridor, spotlighted every year at eMerge Americas.
Freight, customs, and supply-chain apps built for the Port of Miami and the largest US–Latin America trade gateway.
High-polish iOS and Android apps for hotels, restaurants, events, and tourism — the businesses that never stop in a 24/7 city.
RapidDev builds native and cross-platform mobile apps, Next.js web apps and dashboards, full MVP-to-scale product builds, and production AI features for Miami founders — mobile and web ship from one team on shared infrastructure, with LatAm payments and compliance built in when you need them.
No stitching together an app shop and a web agency. We scope and ship your iOS, Android, and web product on shared infrastructure — so everything actually works together.
One codebase, both stores. We build React Native and Expo apps that pass App Store and Play Store review the first time, with the native feel your users expect — in English, Spanish, or Portuguese.
Fast, SEO-ready web apps on Next.js. From investor-facing marketing sites to the logged-in product itself — dashboards, admin panels, and customer portals.
The whole thing, mobile and web, on shared infrastructure. Ideal when you're moving off a Lovable or Bubble prototype that's hit its ceiling and need production code that raises well.
Ship the AI feature your product actually needs — chat, search, or agents — wired to your data with streaming, evals, and cost controls, not a demo that falls over.
You see a working, deployed build every single week. Here's the exact path from a first call to a launched app — five steps, no surprises.

Building a custom app in Miami costs anywhere from $13,000 with RapidDev to over $400,000 with a large agency, depending on who builds it. Here is the honest math on the four realistic paths — with real 2025 South Florida numbers, not a vendor's guesswork.

| Miami / US agency | $120K – $400K+ | 4–9 months |
| Offshore / freelance | $25 – $50 / hr | Highly variable — often 2–3x quoted |
| RapidDev | $13K – $25K | 6–12 weeks to a live, submitted app |
The numbers behind this, sourced
For the price of two to three months of two Miami engineers' loaded salaries, RapidDev ships your entire app — mobile, web, and backend — in 6 to 12 weeks.
App development in Miami with RapidDev costs a fixed $13,000–$25,000, quoted before any code is written rather than billed by the hour. A focused single-platform MVP starts at $13,000; a full mobile-plus-web product with payments and AI features runs up to $25,000.
You get a fixed price before we write a line of code — quoted, not billed by the hour. Every Miami build lands in the $13K–$25K range depending on scope.
Solo founders and pre-seed teams validating one core flow with real users.
Seed-stage startups shipping a fundable v1 to the App Store and the web.
Series A teams replacing a no-code MVP or adding cross-border payments and AI.
A few of the builds we've shipped for Miami founders. Details generalized to protect client confidentiality.
Challenge: A Miami founder had a Lovable prototype for a cross-border payments app but couldn't pass the security review to onboard their first LatAm banking partner.
What we shipped: We rebuilt the backend on Supabase with real RLS, moved payments to Stripe with multi-currency support, and shipped native iOS + Android — clearing the partner's security checklist.
Challenge: A short-term-rental startup's Bubble MVP couldn't handle real listing volume, and every new feature broke booking flows for their Miami and Latin American hosts.
What we shipped: We migrated their data into a proper Postgres schema and rebuilt the product on Next.js with role-based access and a real payments layer, so they could finally scale listings.
Challenge: A medtech team showing at eMerge Americas had a demo that worked on stage but no HIPAA-aware backend and no way to onboard real providers.
What we shipped: We shipped a compliant patient-and-provider app with secure auth, audit logging, and a Supabase backend — ready for their first paying clinics after the conference.
190+ people across 17 countries, a 4.9 rating on Clutch, and 600+ apps shipped. Here's the leadership standing behind your build.
CEO & Founder
Founder of RapidDev, a global software firm whose team has delivered 1,000+ client projects. He helps founders cut through the hype and ship practical, production-grade software — fast.
Columbia University · Harvard Business School · U.S. Navy veteran · 1,000+ client projects
Matt on LinkedInCOO
Runs operations across RapidDev's 190+ person, 17-country team — the person making sure your build ships on time and on scope.
CTO
Owns the technical bar for every build: the architecture, code quality, and security review that has to survive investor diligence.
Dev Lead
Leads the engineers who ship your weekly builds across iOS, Android, and web on shared infrastructure.
Both — that's the whole point of working with us instead of stitching two vendors together. We build your mobile app (iOS and Android from one React Native codebase) and your web app on shared infrastructure, so your data, auth, and payments live in one place instead of three.
Yes — it's one of the most common reasons Miami founders come to us. We architect multi-currency payments, Spanish and Portuguese language support, and cross-border compliance from the start rather than bolting them on later. Roughly two-thirds of funded Miami startups already sell across borders, and we build products that clear payments and pass reviews on both sides.
Yes, and it's very common here. No-code prototypes are great for validation but hit a ceiling on security, scale, and hiring — especially for fintech and payments apps. We migrate your data into a real database and rebuild the product in production-grade code you own, usually without losing any of your existing data.
Most builds land between $13,000 and $25,000, quoted as a fixed price before we start — not billed by the hour. After a free 45-minute scope call we send a concrete feature list, price, and timeline. The band depends on scope: a focused single-platform MVP sits near the bottom, a full mobile + web product with payments and AI features toward the top.
Typically 6–12 weeks from kickoff to a live, submitted app. A focused MVP can ship in 4–6 weeks; a full mobile + web product with AI or cross-border payments runs closer to 9–12. You get a working, deployed build every week, so you're never waiting months to see progress.
No — we work with Miami founders remotely and asynchronously. You'll have a dedicated point of contact, weekly demos, and a shared board. Our team's timezones overlap well with both Miami and Latin America, so if you prefer a video kickoff or working sessions we're happy to schedule around you.
You do — completely. The code lives in your GitHub, the App Store and Play Store listings are under your accounts, and we hand over full documentation at launch. We never hold your product hostage, and you're free to bring the work in-house or hire your own team whenever you want.
That's a big part of what we do for seed and Series A teams here. Miami investors expect a real product, not a clickable mockup — so we prioritize the flows that demo well, ship App-Store-quality polish, and make sure the architecture holds up to technical diligence. Many of our clients raise on the version we ship, including around events like eMerge Americas.
Absolutely — most of the founders we work with are non-technical or first-time technical founders. We handle every technical decision, explain trade-offs in plain English, and give you a product you can maintain or hand to a future CTO. You focus on customers and fundraising; we handle the build.
It comes down to structure, not corners cut. We scope a fixed set of features up front, so there is no open-ended hourly meter. A small, senior-only team does the work directly — you are not paying for account managers, sales overhead, or junior engineers learning on your budget. And we reuse hardened production patterns for auth, payments, and infrastructure instead of rebuilding them each time. An in-house team in Miami carries roughly $140K–$145K base salaries each, plus benefits and months of ramp-up before anything ships; an agency layers overhead on top of the build. We simply do not carry those costs.
Every build includes a 30-day bug-fix window after launch — if something we shipped breaks, we fix it at no extra cost. Beyond that, you can keep us on an optional monthly support retainer for ongoing fixes and new features, or take the code in-house and maintain it yourself. You own the code either way, so you are never locked in.
Small adjustments within the agreed scope are just part of the weekly sprint — you review a working build every week and give feedback we fold in. If you want to add or swap something bigger that changes the scope, we handle it with a simple change order: we tell you the price and timeline impact before doing the work, you approve it, and only then do we build it. No surprise invoices, and no silent scope creep.
