Full-Stack Web Applications
GenosAI builds production-grade web apps built for scale — auth, APIs, databases, and deployment all included. From MVPs shipped in weeks to enterprise platforms built to last years.
What GenosAI Builds
- →SaaS MVPs — Core product loop, auth, billing, and onboarding. Enough to validate, acquire users, and raise a round.
- →Internal tools & portals — Employee portals, vendor management systems, and workflow tools that replace Notion hacks and spreadsheets.
- →API-backed web platforms — REST or GraphQL APIs with documented endpoints, rate limiting, and webhook support.
- →Multi-tenant SaaS platforms — Org-level isolation, team management, custom roles, and usage-based billing at scale.
- →Marketplace & directory apps — Two-sided platforms with listings, search, booking, payments, and review systems.
Who This Is For
Right fit if you:
- Have a validated idea and need an MVP built fast without technical debt
- Are running manual processes that need a proper software layer
- Have an existing product that needs new features or a full rebuild
- Need a technical co-founder equivalent without the equity conversation
- Want code you own and can hand to an in-house team later

Frequently Asked Questions
What tech stack do you use?
We default to Next.js (App Router), TypeScript, PostgreSQL via Supabase, and Vercel for deployment. We adapt to your existing stack if needed — Node/Express, Python/FastAPI, AWS, or GCP.
Do you handle authentication and payments?
Yes. Auth via Clerk or Supabase Auth (email, Google, SSO). Payments via Stripe — subscriptions, one-time charges, usage-based billing. Both are included in production tier and above.
Can you build on top of an existing codebase?
Yes. We audit your existing code first, identify what to keep and what to refactor, and work within your repo. We do not require greenfield projects.
Who owns the code when the project is done?
You do — fully. All source code is yours from day one. We transfer the repo, infrastructure credentials, and all assets on handoff.
How much does a full-stack web app cost?
MVPs start at $5,000. Production web apps with auth, payments, and admin panels run $8,000–$15,000. Enterprise multi-tenant platforms start at $15,000.
