You aren't hiring a dev agency that gets paid whether the app succeeds or fails. We operate on a shared revenue model. We absorb the initial engineering costs and technical risk, meaning we only win if the product actually converts your audience into paying users.
Anyone can prompt an AI to build a simple app today, but scaling is different. Backed by years of experience building for European unicorns, we engineer scalable architecture that won't crash when your audience floods the servers.
We don't just hand over an app and walk away. We provide the complete product framework—from the core user experience and monetization strategy to the exact content angles you need to naturally integrate the product into your existing channels.
We move fast, but we don't rush. We compress the timeline to a revenue-generating MVP without sacrificing quality. No endless development cycles or bloated feature sets—just precise execution to get a high-quality product into your audience's hands quickly.
Great products don't happen by accident. As a digital product design agency, we help startups grow through smart strategy, solid UX, and scalable development from day one.
Define the business logic, core features, and the exact audience pain points the app will solve.
Visualize the user journey with high-fidelity design concepts before a single line of code is written.
Tailored go-to-market strategy to naturally integrate the app into your existing content channels.
From scattered concept to a live, production-ready product. No fragile, duct-taped code.
AI features implemented where they actually add value — not bolted on for show.
You stay in the driver's seat. Your requests and vision are actively incorporated during the build phase.
Fully automated subscriptions, invoicing, and secure payment gateways ready to accept users on day one.
Track your active user base, subscription metrics, and revenue from an easy-to-read dashboard.
Architecture that won't crash when your audience floods in. Built from experience with European unicorns.
Zero agency fees. We absorb the initial engineering costs and risk. We only win when your product converts.
Ongoing maintenance, bug fixes, and feature updates based on real user feedback — not billed by the hour.
Dedicated engineering arm for the long run. You focus 100% on content creation and community growth.
From idea to live product in under 30 days: pitch, align, build, launch—so you always know what stage we're in and what happens next.
We come with a specific opportunity built around your audience—business plan, design previews, monetisation model. You don't need to know what to build. We've done that work already.
We align on your audience's needs, your vision, your preferences. This is a co-founding conversation—not a client brief.
Enterprise-grade MVP in 2–4 weeks. Weekly updates. Zero technical knowledge required from you.
Your dashboard shows users, revenue, and growth in real time. You keep making content. The product keeps making money.
Same attention can fund a flat fee, a launch cycle, or recurring software. We focus on the model that compounds—then we engineer it with you.
You sell attention. They get a recurring customer. You get a flat fee.
