Local context
Wellington business context
Wellington is shaped by the Winter Equestrian Festival, which runs for 13 weeks from January to March. A study reported by the Wellington Town-Crier put the 2025 festival's economic impact at $538.2 million for Palm Beach County, though that is a county-wide estimate, not Wellington alone. Outside the season the village is a residential community served by Wellington Regional Medical Center and local retail.
Major local employers
- Wellington Regional Medical Center. About 1,360 employees.
Sources: Business Development Board of Palm Beach County, Top Employers (figures updated by employers, January 2024); Town-Crier: Study, 2025 WEF delivered $538.2 million in economic impact.

Questions
Frequently Asked Questions
Can we meet in person in Wellington?
No. App369 works remotely and asynchronously from Miami, with written updates and shared progress builds. There are no standing meetings; live calls are available at $100 per 15 minutes.
Do you have experience building equestrian software?
No. App369 has not built an equestrian product that we can point to, and we will not claim it. What we can offer is general booking, scheduling and communication software built on Flutter and Firebase, scoped around what your business does.
Can software be ready before the January season starts?
Possibly, if scope is small and work starts early. A small fixed-price piece can take weeks; larger app timelines depend on scope, so start well before the season and ask for a written estimate.
How long does a typical project take?
It depends on scope. As a rough guide, a marketing website takes 4-8 weeks, a web application 2-4 months, and a mobile app 3-6 months. Every Wellington project starts with a written scope and milestone plan, so you know the timeline before any build work starts.
Do you provide ongoing support?
Yes. After launch we offer maintenance that covers bug fixes, iOS and Android OS updates, security patches, dependency upgrades and small feature work, so your Wellington app keeps working as the platforms change.
What's your pricing model?
App369 uses project-based pricing with a 50/50 payment structure: 50% upfront and 50% on completion. Current ranges are published on our fee structure page, and smaller fixed-price packages are available for well-defined work.
Can you work with existing projects?
Yes. We take over existing codebases, especially Flutter and Firebase apps, for code audits, bug fixes, new features and migrations. Wellington businesses with an app that stalled or a developer who left can start with an audit before committing to a larger build.
