[ In short ]
Lunarion Labs helps Miami companies in fintech, real estate, hospitality, trade and health build, rescue and grow their software: mobile apps, client portals, payment flows, AI assistants, automations and search visibility. We work remotely on Eastern Time, the same working day as Miami. One senior lead owns the project from first call to launch, and every project starts with a fixed-price audit that ends with a written diagnosis and a detailed, prioritized quote.
01The Miami market
Miami's economy has always looked outward. PortMiami and Miami International Airport connect South Florida to Latin America and the Caribbean, and many companies here run sales, logistics or finance across several countries at once. Tourism, cruises, hospitality and real estate remain pillars of the local economy, while Brickell has grown into a dense financial district with banks, wealth managers and a growing number of fintech and payments companies.
Over the past several years the tech scene has grown quickly, with founders and investors moving to the city and remote teams choosing Miami as a base. The ecosystem is younger and more mixed than in older tech hubs: you meet fintech startups next to family-owned real estate groups, hotel operators, import and export firms and wellness brands. Spanish is part of daily business, and a lot of companies serve customers in English, Spanish and Portuguese across the Americas.
That shapes what software has to do. Products here often need to work in more than one language and more than one currency, handle payments from different countries, and look polished enough for a demanding consumer market. Many Miami businesses grew on a patchwork of booking platforms, spreadsheets, messaging apps and a website built by a local agency. When the business scales, that patchwork becomes the bottleneck, and a proper app or portal starts paying for itself.

02Software challenges we see in Miami
Payments across borders
Collecting money from customers in several countries brings currency handling, local payment methods, chargebacks, fraud checks and compliance questions that a basic checkout never planned for. Fintech and trade companies in Miami often run on payment code assembled quickly by different contractors, with keys stored in the wrong places and nobody sure which provider handles what. Every new market makes the problem harder.
Apps that never made it to the stores
Booking, rental and property apps are common Miami projects, and many stall right before launch. The build is mostly done, but App Store review keeps rejecting it, the Google Play listing is stuck, or the developer accounts belong to the freelancer who built it. The company has paid for an app that customers still cannot download.
Bilingual products done halfway
Plenty of products here were launched in English with Spanish added later through copied pages and hardcoded strings. The result is a site or app where half the screens are translated, emails go out in the wrong language and search engines see duplicate content. Fixing it properly means real internationalization in the code, not another round of copy and paste.
Operations running on chat threads
Hospitality, real estate and trade businesses often coordinate bookings, viewings, shipments and approvals over messaging apps and email. It works when the team is small. As volume grows, requests get lost, nobody has a single view of a client, and managers spend their day asking for status updates instead of running the business.
03What we do for Miami companies
Software rescue
For a Miami fintech or payments product, rescue starts with ownership and security: moving every account and API key into the company's name, rotating exposed secrets, reviewing how card data and personal information flow, and stabilizing the checkout. For a stalled app, we take over the code, fix what blocks review and get it published, with the developer accounts registered to your business.
SaaS & business software
We build client portals and business software that fit how Miami companies actually operate: an owner portal for a property manager, a booking back office for a hotel group, a shipment and document tracker for an import business. Each one comes with roles and permissions, an admin panel, multi-currency billing where needed and integrations with the tools your team already uses.
Mobile apps
Mobile is often the main channel for consumer businesses in Miami. We build and finish iOS and Android apps for booking, rentals, memberships and wellness programs, with payments, push notifications, maps and English and Spanish built in from the start. We handle App Store and Google Play review and keep the store accounts in your company's name.
AI & agents
Bilingual businesses are a natural fit for AI assistants that answer customers in English and Spanish, qualify leads and book appointments. We build agents grounded in your own listings, policies and FAQs, with clear limits on what they can say or do, a handoff to a human when needed, and logs so you can review every conversation.
Automation
We replace manual chains with automations: a new booking that creates the invoice, updates availability and notifies the team; a property inquiry routed to the right agent with its history attached; shipment documents collected and filed without anyone forwarding emails. We use custom integrations or tools like n8n, Make or Zapier, depending on what is reliable for your volume.
SEO & AI visibility
Miami is crowded in hospitality, real estate and wellness search, and competition happens in two languages. We fix technical SEO, set up proper English and Spanish versions with correct language tags, build pages around what customers actually search in each language, and work on AI visibility so assistants describe your business accurately when people ask them for recommendations.
04Typical situations in Miami
- A Miami vacation rental company paid for an app that is finished on paper but has been rejected by App Store review several times. The developer stopped replying, and the Apple developer account is in his personal name.
- A payments startup in Brickell is about to sign a larger partner who sends a security questionnaire. The team needs an honest review of how keys, logs and customer data are handled, and a plan to close the gaps.
- A trading company that sells into Latin America manages orders across spreadsheets, email and messaging apps. They want a portal where customers place and track orders in Spanish or English, connected to their accounting system.
- A wellness brand wants an AI assistant on its website and messaging channels that answers in English and Spanish and books appointments. They need it to follow their policies and never invent prices or treatments.
05How a project runs, step by step
- Fixed-price audit. We review the code, access, hosting and contracts, then deliver a written diagnosis with a prioritized, costed plan.
- Secure. Every account and the repository are moved into your company's name, backups are in place and exposed secrets are rotated.
- Fix and build. We stabilize what is fragile, refactor step by step and build what is missing, on a copy of your product.
- Launch and hand over. We publish only after checking, then hand over documentation any senior engineer can pick up.
06How we work with Miami teams
Miami is on Eastern Time, the same as our working day, so calls, reviews, releases and urgent fixes all happen within your hours. We work remotely and do not run a local office; what you get instead is one senior lead who owns your project from the first call to launch and keeps you informed through the Lunarion client app. We work in English and French, and Spanish-language features and content can be built into your product.
We never experiment on your live product. Work happens on a copy or staging environment and is published only after checking, so customers keep booking and paying while we improve things. We refactor step by step rather than starting over. Code, domains, repositories, cloud, app store and payment accounts all end up in your company's name, documented at handover. We can sign an NDA before you share anything.
07What shapes the scope of a Miami project
We do not publish prices: every project is different, and the audit is what sets the quote. These are the factors that weigh most:
- The number of languages, currencies and countries the product has to support
- The payment providers involved and the security and compliance requirements around them
- Whether the app already exists and needs finishing, or must be built from the start
- How many outside systems must be connected, such as booking engines, accounting or listing platforms
- The amount of account and code ownership that must be recovered from previous vendors
08Frequently asked questions
Do you work with Miami companies on Eastern Time?
Yes. Miami is on Eastern Time like us, so calls, releases and urgent fixes follow the same working day. We work remotely, and you can follow progress, decisions and open questions in the Lunarion client app between calls.
Can you build an app in English and Spanish?
Yes. We build internationalization into the code from the start, so screens, emails, notifications and store listings can exist in both languages. We work with you in English or French, and the Spanish content itself can come from your team or a translator you trust.
Our app keeps getting rejected by the App Store. Can you help?
Yes, that is a common rescue. We read the rejection notes, review the code and store listing, fix what Apple or Google flagged and resubmit. We also make sure the developer accounts belong to your company, not to whoever built the first version.
How does a project start?
With a fixed-price audit of your code, access, hosting and contracts. You receive a written diagnosis and a detailed, prioritized quote. It tells you what works, what is risky and what to do first, before you commit to a larger project.
Who owns the code and the accounts?
Your company does. We move code, repositories, domains, cloud, app store and payment accounts into your company's name and document everything at handover. You are never dependent on us, or on anyone else, to access your own product.
Can you sign an NDA before reviewing our fintech product?
Yes. We can sign an NDA before seeing any code, data or documents. For payment and financial products we also limit access to what the audit actually needs and work on copies rather than production data whenever possible.
