Project details
You've got the idea. Now you need something real to put in front of customers.
This takes you from product clarity to a clickable, testable prototype in 5 days — without hiring a dev team or burning through your runway. We start with a focused 2-hour strategy session to lock in your core hypothesis and define exactly what to build. Not everything. The right thing.
From there, we write a clean requirements doc and build a working prototype using Lovable or Replit — functional enough to validate with real users, fast enough to not slow you down.
No bloated sprints. No 3-week discovery phases. No agency overhead.
This is for founders who are past the "should I build this" stage and ready to answer: "will people actually use it?" — with evidence, not assumptions.
The output isn't just a prototype. It's a validation-ready artifact with a defined hypothesis you can test immediately.

As a two-time founder with one exit, I know the biggest risk in building a product isn't technical — it's building something nobody wants. That's the problem I help founders avoid.
I'm CEO of Gearheart and Co-Founder of Beyond the Wow. As an AI-native MVP developer team, we take domain expert founders from idea to revenue-ready Minimum Viable Product in weeks, not months. Before writing a single line of code, we make sure we're building the right thing. Then we move fast.
Our SaaS development standard comes from 14 years of enterprise product work at Gearheart:
SmartSuite — a B2B SaaS development project built from scratch. Reached $1.2M ARR in 4 weeks post-launch, raised $38M, trusted by Capital One.
Globalli — an HR SaaS platform powering payroll across 125+ countries, raised $15M+, SOC2 Type II certified.
Our team is made up of senior Full Stack developers who have shipped production-grade SaaS products at enterprise scale. At Beyond the Wow, we bring that same depth to early-stage founders who need MVP development speed without the technical debt that comes from cutting corners.
WHAT I CAN HELP YOU WITH
Founder Briefing
Before touching code, we help you define your ICP, challenge your value proposition, and confirm whether this Minimum Viable Product is worth building at all — saving you months of work in the wrong direction. ICP definition, value proposition challenge, PMF signal check, monetization logic.
Discovery & Prototype
For founders with product clarity, we turn your knowledge into a clickable prototype in 5 days, ready to validate with real customers. Core hypothesis and scope definition, requirements doc for MVP development, clickable prototype built with Lovable or Replit.
Rescue Diagnosis
Built something on Lovable, Replit, or Base44 but it's breaking in production? We audit the technical and product gaps and give you a clear path forward. Full code review by a senior MVP developer, QA and security audit, product gap analysis, sprint plan and cost estimate.
MVP Development & Landing Page
Validated idea, early customers, ready to invest? We deliver a production-ready Minimum Viable Product with landing page in 3–4 weeks. One core use case, built right. AI-assisted SaaS development (Claude Code, Lovable), database and API integrations, user authentication and onboarding flow, product design components, production-ready deployment.
Sprint Subscription
Ongoing SaaS development support — ship new features and improvements at a regular sprint pace.
MVP DEVELOPMENT SPEED
Legal document analysis SaaS platform with AI chatbot — built in ~2 months.
AI Receptionist for SMBs with CRM integration — MVP development completed in weeks.
Referral System for Dental Clinics, B2B SaaS referral automation — Minimum Viable Product shipped in 3 weeks.
Medical device industry SaaS platform — ICP defined, PMF validated, MVP shipped in 2 weeks.
WHY WORK WITH ME
Been There as a Founder: I've built, launched, and exited SaaS products myself. I work as a partner, not a vendor.
Product Before Code: We ask "should you build this?" before "how do we build it?" Most MVP developer studios skip that question entirely.
AI Speed, No Shortcuts: We use Claude Code, Lovable, and Cursor as real engineers — faster SaaS development without sacrificing the production readiness your first customers need.
Offshore Pricing, Enterprise Standard: Ukraine-based MVP development team. Competitive rates. The same quality we've held for 14 years.
