The MVP Development Agency for the Vibe Coding Era
Greta builds your MVP in 4–8 weeks. We are 20x faster and 100x cheaper than a traditional agency. Production-ready from day one. Maintenance included. No technical co-founder needed.
What is an MVP development agency?
An MVP development agency builds the first working version of your software product. MVP stands for Minimum Viable Product — the simplest version of your idea that real users can actually sign up for, use, and give you feedback on. You can read the full plain English guide to what an MVP is if this is your first time building software.
Most founders try to build an MVP themselves, hire a freelancer, or go to a traditional agency. Each path has a problem: DIY takes too long, freelancers leave you holding the technical debt, and traditional agencies charge $100,000+ and take a year.
A new category of agency emerged in 2024 and 2025 — the vibe coding agency. These agencies use AI-assisted development to build faster, cheaper, and with smaller teams. Greta is the leading vibe coding development agency. We build what traditional agencies charge $100,000+ for, at a fraction of the cost, in weeks instead of months.
Why traditional MVP agencies are broken
Most development agencies were designed for a different era. They hire large teams of developers. They run long discovery phases. They charge by the hour. The result: a simple MVP takes 9–12 months and $80,000–$200,000.
By the time your product launches, competitors have shipped three versions. Investors have moved on. Your market has shifted.
The other problem is what happens after launch. AI-built and vibe-coded apps accumulate technical debt 10x faster than traditionally built ones. Most agencies hand you the code and disappear. That leaves you with a product that works today but falls apart in six months.
Greta is different on both counts: we build fast AND we maintain what we build.
Why Greta?
20x faster
Traditional agencies take 6–12 months. Greta delivers a working MVP in 4–8 weeks. That is not a marketing claim — it is the result of using our own AI platform instead of a large developer team.
100x cheaper
We do not need large dev teams or long timelines. Our AI platform does the heavy lifting. The savings go directly to you — not to a team of $150/hour developers.
Production-ready from day one
We handle what most vibe coders skip: security, compliance, scalability, and performance. Your MVP is built to handle real users from the moment it launches — not just demos.

Our build process
- 01
Discovery call
One hour. We learn your idea, your users, and your goals. No jargon. No templates. No hard sell. Just an honest conversation about what you need.
- 02
Scope and compliance review
We map exactly what to build and identify which compliance requirements apply to your industry — PCI-DSS, HIPAA, GDPR, FERPA, or others. You get a clear written scope.
- 03
Design and prototype
Clickable mockups so you can see and feel the product before a single line of code is written. Fast feedback rounds — usually 24 to 48 hours.
- 04
Build
Our AI-assisted platform builds your MVP at a pace traditional teams cannot match. You get weekly updates and a private staging environment to review as we go.
- 05
QA and security
We test every user flow, run security checks, and verify that compliance requirements are met before anything goes live. No cutting corners.
- 06
Launch and handover
Your product goes live. You get full code ownership, documentation, and a handover call. If you want ongoing maintenance, we offer that as a service — no lock-in.

What founders ask us about MVP development
What is an MVP development agency?+
An MVP development agency builds the first working version of your software product. MVP stands for Minimum Viable Product — the simplest version of your idea that real users can sign up for and test. An agency handles the full build so you do not have to.
How long does it take to build an MVP in 2026?+
With Greta, most MVPs are delivered in 4 to 8 weeks. Traditional agencies typically need 6 to 12 months for the same scope. The difference is our AI-assisted build process, which removes the slowest parts of traditional development.
How much does MVP development cost in 2026?+
Traditional agencies charge $50,000–$200,000 for an MVP. Greta delivers the same quality at a fraction of that cost — typically 10x to 100x cheaper — because we use our own AI platform instead of large developer teams. Book a free call for a real number within 48 hours.
What is the difference between an MVP and a full product?+
An MVP includes only the core features needed to test your idea with real users. A full product has every feature you ever wanted. The point of an MVP is to find out which features actually matter before spending big. Most products that skip the MVP stage waste money building things users do not want.
What industries does Greta build MVPs for?+
Greta builds MVPs across fintech, edtech, healthtech, insurtech, SaaS, ecommerce, and more. Every vertical has different compliance requirements — Greta handles whichever apply to your project.
Does Greta provide maintenance after launch?+
Yes. AI-built apps accumulate technical debt faster than traditionally built apps. Greta offers ongoing maintenance as a service — patches, updates, and refactoring included — so your product stays healthy after launch.
