Project details
Turn your idea into a clickable prototype in just 5 days.
With our Discovery & Prototype sprint, we align on key flows, validate UX, and deliver an interactive demo you can use for fundraising, stakeholder alignment, or early user testing.
Our process starts with a concept workshop to capture your vision, then we build UI with AI-powered tools (Lovable, v0) and refine daily with your feedback. In less than a week, you’ll get a polished prototype, annotated screens with product logic, and detailed full stack MVP specifications including user stories and backlog.
This sprint saves weeks of delays, eliminates guesswork, and helps you raise capital faster. Whether you need clarity before coding or an investor-ready demo, you’ll leave with a tangible product, tested ideas, and clear build recommendations - without wasting months on specs or half-built MVPs.

I'm a 2x founder with one exit and 14 years of experience building B2B SaaS startups. I know firsthand what it means to bet on an idea, run out of runway, and figure out product-market fit the hard way. That's why I work with founders — not as a vendor, but as a partner who's been in the same position.
I lead Gearheart and co-founded Beyond the Wow — an AI Developer and Startup MVP studio. Our full stack developer and AI Developer team specializes in SaaS MVP Development and AI Integration, helping founders go from idea to revenue-ready product in weeks. Behind me is a team of 23 senior engineers with 14 years in SaaS — together we've shipped 84+ products for 70+ clients across 7 countries.
Whether you're looking for a SaaS Developer partner, need AI SaaS Development, or want a team that understands SaaS Business Development as much as the code — we've done it from both sides of the table.

💡 WHY WORK WITH US
- Been There as a Founder: I've built, launched, and exited SaaS products myself. Our startup mvp process — and our full stack developer team — is built on real founder experience.
- Product Before Code: We ask "should you build this?" before "how do we build it?" Most AI Developer studios skip that question entirely.
- AI Speed, No Shortcuts: Our full stack developer and AI Developer team uses Claude Code, Lovable, and Cursor as real engineers. AI Integration built in by default — 2–4x faster without cutting corners.
- Offshore Pricing, Enterprise Standard: Ukraine-based SaaS MVP Development team. Competitive rates. The same quality we've held for 14 years.
Our Our engineers work across the full spectrum: Python Developer backends, React Developer frontends, REST API and API Automation layers, Machine Learning pipelines, and Twilio integrations. Whether you need a Software Developer, Web Developer, or App Developer — one team covers it all.
