Have an app idea? In 7 days, know exactly what to build, what it costs, and how it makes money. Then our in-house team builds it for web, iOS and Android at a fixed price.
Built on a production-grade stack
From app idea to launch in three steps, with a fixed price before you commit to a build.
In 7 business days: the 3 to 5 features your MVP actually needs, a fixed build price and timeline, and a plan for how your app makes money. Delivered on time or a full refund, and 100% credited to your build.
Custom app development for web, iOS and Android by our in-house team of senior engineers, in 4 to 8 weeks. The price is locked from your Blueprint. You pay per milestone, never for one you haven't approved, and you own 100% of the code.
30 days of post-launch fixes are included with every build, backed by our 30-day money-back guarantee. After that, optional monthly support keeps your app running smoothly as you grow.
30-day money-back guarantee
If you don't like your product within 30 days after launch, you get all your money back.
We do this because we believe in our team and the products we build.
100% of what you paid for development, not a credit or a discount.
Use the live product with real users before you decide.
Your 30 days of post-launch fixes are included either way.
Why Synaptix
Most agencies build what you ask for and send you off to figure out the rest. That's why most apps never make a dollar. We know what users will pay for, what makes them stay, and what kills a launch. Then we build your app around that from day one, across web, mobile and AI.
You're not hiring developers. You're hiring a team that knows what it takes to make an app profitable.
Modern, scalable web apps built with Next.js, React, and cloud infrastructure
Cross-platform mobile apps for iOS and Android using React Native
Custom AI chatbots and assistants powered by LLMs for your business
Retrieval-augmented generation systems for intelligent document processing
Workflow automation and process optimization solutions
Autonomous AI agents integrated into production web applications
Technical MVP Blueprint
They start coding immediately. Six months later, they realize they built the wrong product for the wrong market with the wrong tech stack. A minimum viable product (MVP) only works when it's built around what users will actually pay for.
Our Technical MVP Blueprint prevents this. In 7 business days you get:
100% credited to your build
Most founders waste 6 months and $50k building the wrong thing. Our blueprint prevents this for the cost of a single developer day.
Money back guarantee: delivered in 7 business days or a full refund

High-level system design, technology choices, and scalability considerations, so you never pay for a rewrite
How your app makes money: the revenue model, what to charge, and the path to profitability
