We are not a national agency with a Miami landing page. Appsurd is one squad at 2125 Biscayne Blvd, shipping production software every 48 hours for teams that can walk to our office — and for the ones that will only ever meet us on Zoom.
Search "app development Miami" and most of what you'll find are national firms running the same page in forty different cities, each with a coworking address and a city name swapped into the headline. It's a legitimate way to run a marketing funnel. It is not the same thing as being in Miami.
Appsurd operates from 2125 Biscayne Blvd, in the corridor between Downtown and the Design District. That's the only address we have. When a client in Brickell wants to sit in a room and argue about a data model, that happens in person, usually the same week. When a founder in Wynwood needs someone in the building for an investor demo, we're twelve minutes away.
The practical difference isn't sentiment, it's latency. We work Eastern time, which means a question asked at 9am is answered at 9am — not overnight, and not at the end of a nine-hour offset. Over a three-month build, that difference compounds into weeks.
We are also honest about the other half: most of our clients are not in Miami, and the work is remote-first by design. The reason the local piece matters is that somebody on your project is accountable in your time zone and reachable at a real address. That is a low bar that a surprising number of agencies do not clear.
Miami's software market doesn't look like Austin's or Seattle's, and building here as though it does is the most common expensive mistake we see.
The capital is real. South Florida startups raised $4.13 billion across 376 deals in 2025, a 49% jump on the year before, taking 71% of all venture dollars in Florida, with an average deal size of $11 million, according to the eMerge Americas Insights Report. The Miami-Dade Beacon Council counts more than 2,000 startups supporting roughly 90,000 jobs and six active unicorns in the region.
But the composition is unusual in three ways that change how you should build.
It's a services and trade economy first, tech second. The largest software budgets in this city sit inside real estate, hospitality, marine, logistics, healthcare and legal firms — not inside software companies. That means most Miami app projects are internal tools, operations platforms and customer portals for established businesses, and they are judged on whether they replace a spreadsheet and a WhatsApp group, not on whether they look like a Bay Area consumer app.
It's bilingual and cross-border by default. A product launched here frequently needs Spanish at parity with English on day one, Latin American payment rails, and content that reads as native rather than machine-translated. Retrofitting that after launch costs several times what building for it costs.
Hiring is expensive and competitive. The average Miami tech salary is around $95,000, and that's an average, not what a senior mobile engineer costs. Add benefits, equipment, recruiter fees and the three-to-six months it takes to hire and ramp, and a two-person in-house team is a six-figure quarterly commitment before a single feature ships.
Miami is not one market. The brief changes noticeably depending on which part of the city it comes from.
Fintech, private banking, crypto, LatAm treasury. Compliance and audit trails are usually the hard part, not the interface. Expect security review to be a project phase in its own right.
Consumer brands, creative agencies, hospitality concepts, marketplaces. Design bar is unusually high and the deadline is normally tied to a launch event, so the schedule genuinely cannot move.
Professional services, legal, healthcare admin, property management. Almost always integration work: the app is the friendly surface over a system nobody wants to replace.
Established firms, family offices, multinational Latin American HQs. Procurement is formal, decisions are slow, and the winning proposal is the one with the clearest maintenance story.
Marine, yachting, private clubs, members-only services. Offline-first behaviour matters more than anyone expects — connectivity on the water is not a rounding error.
Logistics, freight forwarding, import/export, trade. Barcode scanning, driver apps, customs paperwork and the reality that warehouse phones are three OS versions behind.
Small business, food, community services. Spanish-first, budget-real, and usually better served by a tight MVP than by a platform.
Hotels, restaurants, nightlife, events. Seasonal traffic spikes are the engineering problem — the system has to survive Art Basel and Formula 1 weekend, not an average Tuesday.
Ranked roughly by how often the brief lands in our inbox, not by which sounds most impressive.
Miami's defining industry, and the most consistent source of software work. Broker portals, HOA and condo management, tenant and resident apps, showing and inspection tooling, construction progress tracking. The recurring technical problem is MLS and property-data integration, where the data is messy, licensed, and rate-limited.
Booking, ordering, loyalty, guest messaging, staff scheduling. The differentiator here is peak-load behaviour and POS integration — a reservation system that degrades gracefully at 8pm on a Saturday in season is worth more than one with a nicer interface.
Brickell's specialty and the most regulated work we do. KYC and AML flows, cross-border payments, custody interfaces, LatAm remittance rails. We plan for security review, penetration testing and audit logging from the architecture stage, because bolting them on afterwards means rewriting.
A genuinely Miami vertical that almost no national agency thinks about. Charter booking, fleet and maintenance management, crew coordination, marina operations. Offline-first sync is mandatory, not a nice-to-have, because the vessel leaves cell coverage and the app still has to work.
Miami is the LatAm trade gateway, and Doral runs on it. Driver and warehouse apps, shipment visibility, customs documentation, EDI. The apps have to run on cheap Android hardware in a metal building with bad signal, which rules out a lot of fashionable architecture.
Patient intake and scheduling, telehealth, remote monitoring, clinic operations, concierge medicine. HIPAA shapes the whole build — data handling, logging, vendor selection, even which analytics tools are allowed near the app.
Client portals, intake automation, document workflow, matter management, and increasingly retrieval over document sets. Our work for the Supreme Court of Ohio is the public version of this problem: accessibility, predictable performance and zero tolerance for a wrong answer stated confidently.
Donor engagement, program management, volunteer coordination, grant reporting. We built the donor engagement platform for the American Cancer Society, where the constraint was institutional trust rather than feature count.
Roughly a third of Miami startups are founded by Latino entrepreneurs, per the Beacon Council, and a large share of the region's commercial activity runs through Latin America. If you build here, bilingual is a starting condition, not a phase two.
The mistake is treating it as translation. Real parity means the copy is written twice, not translated once; that layouts survive Spanish strings running 20–30% longer than English; that dates, currency and address formats switch with the locale; that push notifications and transactional email arrive in the user's language; and that support content, App Store listings and screenshots exist in both.
There's a technical tail too. Latin American payment methods — Pix in Brazil, SPEI in Mexico, local card networks and cash-voucher rails — behave differently from a US card charge, with different failure modes and settlement times. Phone number and tax ID validation vary by country. So does what "a valid address" means.
We build this in from the schema up, because the cost of retrofitting localization into a shipped product is routinely several times the cost of designing for it. Half our squad works bilingually, which is less a selling point than a requirement for doing this properly.
Real ranges from real engagements, not a calculator designed to capture your email address. Every range assumes design, engineering, QA and deployment — not engineering alone.
| What you're building | Typical range | Time to launch | When this is the right scope |
|---|---|---|---|
| Validation MVP | $15k – $35k | 4 – 8 weeks | One core workflow, one platform, real users. The goal is a decision, not a product. Most Miami founders should start here and most want to skip it. |
| Production mobile app | $45k – $120k | 3 – 5 months | iOS and Android, accounts, payments, notifications, an admin surface, store submission handled. The most common brief we get. |
| Internal operations platform | $60k – $180k | 3 – 6 months | Replacing spreadsheets and WhatsApp for a real operating business, integrated with the systems you already run. Where most Miami software budget actually goes. |
| Regulated build (fintech / health) | $120k – $400k+ | 5 – 12 months | KYC/AML or HIPAA, audit logging, penetration testing, formal security review. The compliance work is a real fraction of the cost, and pretending otherwise is how these projects fail. |
| AI feature inside an existing product | $25k – $90k | 4 – 10 weeks | Retrieval over your own content, agent workflows, document processing. Priced separately because it usually lands on top of software that already exists. |
| Productized squad (retainer) | From $4,995/mo | First delivery in 48 hrs | Continuous product work with shifting priorities. Unlimited requests, pause anytime, no change orders. Cheaper than one senior hire in this market. |
| Ongoing maintenance | $1.5k – $6k/mo | — | OS and store policy updates, dependency and security patches, monitoring, small changes. Not optional: iOS and Android both ship breaking changes yearly. |
Three things that move a Miami number more than anything else. Integrations — every third-party system, especially MLS, POS and legacy ERPs, adds cost proportional to how badly it's documented. Compliance — HIPAA or financial regulation can add 30–50% to a build, and it is not a line item you can defer. Bilingual parity — cheap if designed in, expensive if added later.
For comparison: a single senior developer in this market costs roughly $95,000 a year on the Beacon Council's average and materially more at senior level, before benefits, equipment and recruiting. That is the arithmetic on the comparison page, and it's the reason the retainer exists.
Most Miami teams come to us in one of three situations. The engagement model follows the situation, not a rate card.
The productized squad: engineers, designers, a PM and QA on a flat monthly fee, unlimited requests, first delivery inside 48 hours of kickoff. From $4,995/mo, pause or cancel anytime.
Best when you have a roadmap and no team, or a team that is already at capacity.
Staff augmentation: our engineers embed in your repo, your standups, your Jira. You keep ownership of architecture and process; we add throughput without a 3–6 month hiring cycle.
Best when the product direction is settled and the constraint is delivery capacity.
Advisory and AI implementation: a fixed-scope audit that ends in an architecture, a build plan and a real number — not a slide deck. From $4,995.
Best when the decision is still open and an expensive wrong turn is the actual risk.
All three are covered by a 30-day money-back guarantee, with no lock-in contract and no exit fee. If it isn't working, you leave. See all services or the side-by-side comparison against hiring in-house.
The same sequence whether you're in Miami or three time zones away. The timelines are the ones we actually hold ourselves to.
Thirty minutes. We map the problem, the constraint you're actually up against, and whether we're the right shape for it. If we're not, we say so — we'd rather refer you out than run a bad engagement.
Day 0 · 30 minutesYou get the build shape, the stack, the risks we can see, and a real cost range in writing. No pressure to sign, and the document is yours whether you hire us or not.
Within 2 business daysRepo, CI, staging, error tracking and analytics stood up on day one. You get access to everything from the start — there is no black box and no "we'll show you at the end."
Day 1Something real and reviewable inside 48 hours of kickoff. Not a wireframe — deployed, clickable work on a staging URL you can send to a stakeholder.
Within 48 hoursNew work lands every two days for the length of the engagement, each increment reviewable on staging. Priorities can change between any two deliveries; that's the point of the cadence.
OngoingApp Store and Play Store submission handled, monitoring wired up, documentation written for whoever maintains it next. If that's your team, we do a live handover; if it's us, we move to a maintenance retainer.
At releaseDeliberately boring choices at the infrastructure layer, aggressive ones at the AI layer. Boring infrastructure is what lets a small team maintain a large surface area.
| Layer | What we use | Why this and not something else |
|---|---|---|
| Mobile | React Native (Expo), Swift / SwiftUI, Kotlin | React Native when one codebase should serve both stores — most business apps. Native when the product depends on the camera, Bluetooth, background location, or hardware the bridge handles badly. |
| Web | Next.js, React, TypeScript, Tailwind | Server rendering matters for anything that needs to be found in search, and TypeScript catches at compile time the class of bug that otherwise shows up in a store review. |
| Backend | Node / TypeScript, Python for ML paths, Postgres | One language across client and server means one team can own the whole feature. Postgres because relational data is still relational, and because it will outlive whatever is fashionable this year. |
| Infrastructure | Vercel, AWS, Supabase, Cloudflare | Managed platforms until scale genuinely demands otherwise. Paying for infrastructure you can't operate is a slower failure than paying for one you can. |
| AI layer | OpenAI, Anthropic, embeddings + retrieval, agent orchestration | As an official OpenAI partner we build retrieval and agent workflows as first-class product features, not a chatbot bolted onto a finished app. |
| Delivery | GitHub, CI on every commit, staging per branch, Sentry | Every increment is deployed and reviewable, which is the only way a 48-hour cadence stays honest instead of becoming a demo. |
The full picture, including how we evaluate a new tool before it touches client work, is on the stack page. How we handle client data and access is documented on the security page.
The honest version. There are situations in each of these columns where the other option is the right call, and we'll tell you when we think you're in one.
| Appsurd | Local dev shop | Offshore agency | Hiring in-house | |
|---|---|---|---|---|
| Time to first shipped work | 48 hours from kickoff | 2–6 weeks after contract | 3–8 weeks including onboarding | 3–6 months to hire and ramp |
| Cost model | Flat monthly, unlimited requests | Hourly or fixed-bid per change | Low hourly, billed by headcount | Salary, benefits, equity, overhead |
| Team you get | Engineers, design, PM, QA in one squad | Usually engineers only | Assigned pool, rotates | Whoever you can hire and keep |
| Overlap with your working day | Full US business hours, Miami time | Local hours | Partial, often a 9–12 hour offset | Full |
| Changing direction mid-build | Between any two deliveries, no change order | Change order and re-quote | Change order, often a re-scope | Free, but capacity-bound |
| Exit | Cancel anytime, code and docs are yours | Contract term, sometimes an exit fee | Notice period, IP terms vary | Severance and lost knowledge |
Two things worth saying plainly. If your build is genuinely a one-week fix, a flat monthly squad is the wrong instrument and an hourly contractor is cheaper. And if you have a stable roadmap five years out, hiring in-house wins on cost eventually — the reason to use us is speed and optionality, not price alone. We put the arithmetic on the comparison page rather than hiding it.
Public, named engagements — the kind you can verify rather than take on faith. Every one of these went to production.
A donor engagement platform for one of the largest health nonprofits in the country, where the constraint was trust: donation flows, accessibility and data handling all had to hold up to institutional review.
A dealer operations portal used by staff who have no patience for software — which makes it a good test of whether an interface actually works under time pressure.
An AI-native learning platform built with retrieval over institutional content, in an environment where a confidently wrong answer is worse than no answer.
A public legal portal, which means accessibility compliance and predictable performance for the whole public, not just users on new phones.
An operations dashboard where the requirement was uptime and clarity under load, in a procurement and security environment with no tolerance for improvisation.
Appsurd is the productized squad built by Bolder Apps, our parent company, which has been shipping production software since 2019 across 25+ brands and organizations.
A Miami engagement usually starts with a thirty-minute call, in person if you're nearby and on Zoom if you're not. We'd rather spend it on the constraint you're actually up against than on a capabilities deck.
Within two business days you get a written scope: the shape of the build, the stack, the risks we can see from here, and a cost range. That document is yours whether you hire us or not, and several people have used it to brief someone else. That's fine — an accurate scope is worth more to this city than a signed bad one.
If you go ahead, kickoff is day one and the first deployed increment lands inside 48 hours. You'll have the repo, the staging URL and access to everything from the start. Whether we're the right fit is usually obvious by the end of week one, which is the entire point of running it that way instead of asking you to trust a proposal.
Yes — 2125 Biscayne Blvd, Miami, FL 33137, and it's the only office we have. You can call +1-645-444-1069 and reach the team that would do your build.
It's a fair question to ask any agency ranking for this search, and the answer is often a virtual address in a coworking space serving forty other city pages. Ask for the street address and ask who sits there.
A validation MVP runs $15k–$35k, a production mobile app $45k–$120k, an internal operations platform $60k–$180k, and a regulated fintech or healthcare build $120k–$400k and up. Our productized squad starts at $4,995/mo with unlimited requests.
The three factors that move those numbers most are integrations with systems you already run, compliance requirements, and whether bilingual parity is designed in from the start or bolted on later. Full breakdown is in the cost table above.
Yes, and at parity rather than as a translation layer. Copy gets written twice, layouts are tested against longer Spanish strings, locale-specific dates, currency and validation are handled, and store listings ship in both languages.
We also handle Latin American payment rails where the product needs them, which behave differently from US card processing in ways that matter for failure handling and settlement.
Kickoff is typically within a week of a signed scope, and your first deployed, reviewable increment lands inside 48 hours of kickoff. After that, new work ships every two days.
Compare that to hiring: three to six months to find and ramp a senior engineer in this market, assuming the search succeeds first time.
Yes. Clients in Brickell, Wynwood, Coral Gables and the Beach regularly come to Biscayne Boulevard, or we come to you. Kickoffs and hard architecture arguments are better in a room.
Day-to-day delivery is still remote and asynchronous, because that's what a 48-hour cadence requires. We're not going to pretend standing meetings make software faster.
Most of our clients are outside Miami — across the US and internationally, all remote-first. The location pages exist because local context genuinely changes a brief, not because we bill by zip code.
We also cover the rest of South Florida: see all locations.
React Native for most business apps — one codebase serving both stores, which halves the maintenance surface and matters more than people expect over three years.
Native Swift or Kotlin when the product depends on hardware the bridge handles poorly: sustained camera work, Bluetooth peripherals, background location, or heavy on-device processing. Marine and logistics briefs in this region tip native more often than average because of offline sync and hardware integration.
We handle it, including store listings, screenshots, privacy declarations, and the review back-and-forth. Both stores reject builds for reasons that have nothing to do with code quality, and knowing the current rules saves weeks.
For bilingual products we submit localized listings in both languages, since store search is per-locale.
Often, yes — it's a common brief here, usually after an offshore engagement or a solo contractor stalled. We start with a fixed-scope audit of the existing codebase and tell you plainly whether it's worth continuing or cheaper to rebuild.
We'll give you that answer even when it's the one that makes the engagement smaller. A half-finished codebase you can't hire against is a worse outcome than an honest restart.
Appsurd is the productized AI-native squad built by Bolder Apps, our parent company, which has shipped software since 2019 across 25+ brands and organizations. Same people, different commercial shape.
Bolder Apps, Synergy Labs and Ever Tech Solutions are sister companies under the same ownership. We disclose that rather than presenting them as unaffiliated alternatives — see our about page.
You do, in full, from the first commit. The repository is yours, hosted under your organization where you prefer it, and you have admin access from day one.
There is no clause that keeps a component library or a framework we wrote hostage. If you cancel, you keep everything, including the documentation and the deployment configuration.
You keep the code, the repos, the credentials and the docs. There is no exit fee, no notice period and no clawback of work already delivered.
There is also a 30-day money-back guarantee at the start, which exists because the honest way to prove a 48-hour cadence is to run it, not to describe it in a pitch.
By people, using AI tooling deliberately and reviewing everything before it merges. Nothing reaches your repo without a named engineer accountable for it.
The reason we talk about it at all is throughput: agentic tooling is why a small squad can hold a 48-hour cadence. It is not a substitute for engineering judgment, and we don't pretend it is.
Yes, on a maintenance retainer — OS updates, store policy changes, dependency and security patches, and monitoring. Mobile apps are not finished at launch; iOS and Android both ship yearly changes that break things.
If you'd rather your own team took it over, we do a live handover and write the documentation for it. Either answer is fine; being unclear about which one is happening is not.
Yes. Send yours and we'll sign it, or we'll send ours. Either way it happens before the scoping call, not after.
We work across South Florida. Pick the market closest to you, or start at the locations index.
Thirty minutes, no deck. Bring the problem; leave with a shape, a range, and a timeline you can take to your board.
