The biggest risk for any startup is spending 6 months building something nobody wants. We help founders cut through feature bloat, build the core validated value proposition, and launch to real paying users in weeks instead of quarters.
3 to 5 Week Launch Sprints • Fixed-Price Guarantee • Built to Scale to Series A
Groooh builds production-grade MVPs for early-stage founders in 3 to 5 weeks. We lock a fixed scope around one core user problem, build with modern Next.js/React Native starter primitives and AI-assisted workflows, and deliver working software demos weekly at ~20% below standard agency rates.

The biggest risk for any startup is spending 6 months building something nobody wants. We help founders cut through feature bloat, build the core validated value proposition, and launch to real paying users in weeks instead of quarters.
No open-ended hourly billing traps. We define the scope, agree on a fixed fee, and commit to an exact launch date in writing.
We don't use clunky no-code hacks that break at 1,000 users. We build with clean TypeScript, React, and PostgreSQL architectures that scale seamlessly to your Series A round.
You see working software every 7 days on a live staging URL. No guessing, no surprises, just relentless engineering velocity.
Scoping sprint, core flow wireframing, clickable Figma prototype, and fixed-price technical specification.
Repository setup, database architecture, user auth, and primary frontend layout with live deployment.
Building the primary value workflow, Stripe billing, API integrations, and weekly live demos.
End-to-end QA testing, analytics instrumentation, cloud deployment, and full code handoff.
We combine battle-tested modular primitives with modern AI-accelerated workflows to launch startup MVPs in 3 to 5 weeks at ~20% below standard agency rates:
Clickable Interactive Prototype & Scoping Sprint (1 to 2 weeks): $3,800 to $7,500 (complete Figma UX prototype, investor-ready demo, fixed technical spec)
Core Functional Web or Mobile MVP (3 to 5 weeks): $15,000 to $32,000 (production app, user auth, Stripe billing, database, cloud deployment, analytics)
Multi-Platform or AI-Powered Startup MVP (5 to 7 weeks): $28,000 to $48,000 (web + mobile iOS/Android or custom LLM/agent integration, full production launch)
Every MVP includes 100% intellectual property ownership, zero vendor lock-in, and 30 days of post-launch warranty support.
| Capability | Standard / Stack |
|---|---|
Frontend | Next.js 15, React 19, TypeScript, Tailwind CSS, Shadcn UI |
Mobile | React Native, Expo EAS (single codebase for iOS & Android) |
Backend & Database | Supabase, PostgreSQL, Node.js, Prisma ORM, Redis |
Payments & Auth | Stripe Checkout & Billing, Clerk Auth, Supabase Auth |
Analytics & Host | PostHog, Vercel, AWS, Sentry error monitoring |
A focused MVP with one core workflow, authentication, and billing takes 3 to 5 weeks. We eliminate unnecessary feature fluff so you can get into the market and gather real customer feedback fast.
Our rates run ~20% below traditional dev agencies because AI-assisted workflows cut routine setup time in half. A clickable prototype costs $3,800 to $7,500; a full production MVP costs $15,000 to $32,000. Every quote is fixed-price.
No. Unlike fragile no-code builders (Bubble/Webflow), we build with modern, enterprise-standard TypeScript, Next.js, and PostgreSQL. The code is modular and clean, ready to scale seamlessly through your Seed and Series A rounds.
We lock a fixed core scope at kickoff to protect your launch date and budget. If you discover new feature ideas along the way, we log them into a prioritized 'V2 backlog' to ship immediately after the initial launch.
We build both. For web, we use Next.js; for mobile, we use React Native so you launch on both Apple App Store and Google Play from a single codebase.
Yes. Every production MVP includes full Stripe integration (subscriptions, one-time payments, or usage billing) so you can charge customers on day one.
You own 100% of the code, repositories, designs, and credentials from day one. There is zero agency lock-in.
We give you access to a shared Slack channel, private GitHub repository, and host a weekly live demo where you test the latest working build on a staging environment.
Yes. Many of our recent MVPs incorporate AI features: custom LLM prompts, streaming text generation, vector embeddings, and automated agent workflows.
We provide 30 days of free bug-fix warranty support. After that, we can continue as your fractional engineering team or help hand off the codebase to your first full-time hire.
