Why Rebelled
NYC has more startups per square mile than almost anywhere on the planet. It also has some of the most expensive dev agencies in the world. Manhattan shops routinely charge $200k+ for an MVP, and a lot of that money goes to office rent on Park Avenue, not to building a stronger product. Too many NYC founders burn through their seed round on a partner who hands over code and disappears.
We work differently. Our process starts with validation before we write a line of code. We stress-test the idea, design the product, and build it properly. Then we stay in the game through launch. We are based in Melbourne, Australia, which means you get a dedicated team at a fraction of what a comparable NYC agency would charge, with no compromise on quality.
New York's strength in fintech, media, health tech, and marketplace businesses creates a perfect environment for consumer app founders. If you are building in any of those spaces, you need a partner who understands both the user experience standards your market expects and the commercial pressure to ship something that works. We build products that hold up when investors look under the hood.

What we build
We build across mobile, web, and cross-platform. The technology choice is driven by your users and your goals, not by what our team happens to prefer.
Built for speed and scalability. We scope precisely so you launch fast without burning runway on features your first users don't need yet. NYC moves quickly, and your build process should too.
Fast, focused, and built to validate. We scope ruthlessly so you launch with what matters, get real user feedback, and build from a position of knowledge rather than assumption.
Payments, savings tools, lending platforms, and financial dashboards. New York is the financial capital of the world, and we build fintech products that meet the bar your users and investors expect.
Subscription software with clean architecture. Built to retain users, grow MRR, and scale without a complete rewrite when you hit traction.
How it works

Before we build anything, we make sure it is the right thing to build. We validate your strategy, design your brand from scratch, and create a hi-fidelity prototype that looks and feels like the finished product.
What you get

What you get
Phase three
You have users, you are making money, and you are ready to scale. We coach you through growth until you know exactly what to do next.
Industries
New York's economy spans finance, healthcare, media, and tech. These are the sectors where we work most often with NYC founders and understand the landscape.
Payments, lending, savings, and financial management tools. With Wall Street around the corner, NYC founders building in fintech need products that meet institutional-grade expectations from day one.

Manhattan agencies regularly charge $150,000 to $300,000+ for an MVP. Rebelled delivers quality apps in the $30,000 to $150,000+ range depending on scope and complexity. Our Inception phase (strategy, branding, and hi-fidelity design) starts at $7,200 and takes 2 to 4 weeks, so you validate before committing to a full build. Our cost guide breaks down what drives the price.
Our three-phase process runs Inception (strategy and design), Invention (development), and Ascension (launch and growth). From first call to live app, most founders are looking at 12 to 16 weeks for a quality MVP. Any timeline significantly shorter usually means scope cuts you will regret.
We work across time zones every day. Our team overlaps with US East Coast hours in the morning (your time), and we run weekly video demos, async Slack communication, and a process designed for distributed collaboration. Most of our international founders say the time zone actually works in their favour because they wake up to overnight progress.
No. We specifically work with non-technical founders. Our job is to make the technical side invisible so you can focus on your business, your users, and your growth strategy. You will understand what is being built at every stage without needing to read a single line of code.
NYC agencies carry some of the highest overheads in the world, and that cost gets passed directly to you. We deliver the same calibre of product at a smarter price point because our cost base is different. You get a dedicated team, weekly demos, and a proven process, without the Manhattan markup. We also build founders, not just apps. You get the strategy, the growth playbook, and the ongoing support to turn your product into a real business.
Yes, and we insist on it. Our Inception phase pressure-tests your idea against real user needs before we write a line of code. This protects your investment and gives you the confidence to build knowing you are solving a problem people will actually pay for.
