Lovable, Bolt, v0, Replit and Cursor get founders to a working MVP faster than ever. Then the hard part starts: every fix breaks something else, the AI goes in circles, Supabase keys or database rules may be exposed, payments fail, and nobody is sure the app will survive real users. Cosmos Studio picks up AI-built MVPs at this stage and finishes them properly.
One senior team covers what founders usually cannot do alone: code review and security, backend and database, authentication and payments, cloud setup on AWS or Vercel, and the product and UX thinking that turns a prototype into something people pay for. Frontend and design are done in-house; backend, cloud and security work is done with senior engineers we work with on every project.
If two or more of these sound like your project, it is time for a senior team to take a look.
You ask the AI to fix one bug, and two features that worked yesterday stop working.
The code base has grown so large and tangled that every new prompt feels like a risk.
API keys in the front end, open database tables or missing Supabase row-level security, and no one has checked.
Sign-up, password reset, Stripe subscriptions or webhooks fail for real users, not in the demo.
Pages slow down as data grows, hosting costs climb, and there is no proper deployment, backups or monitoring.
You are raising or onboarding your first big customers, and you need to know the product will pass a technical review.
We keep what works, fix what is risky and rebuild only what has to be rebuilt. These are the areas AI-built MVPs need most.
We review the code and database for exposed API keys and secrets, missing row-level security, open storage buckets and unsafe endpoints, then fix them in order of risk.
We clean up the data model, migrations and API logic generated by AI tools, move business logic to the server where it belongs and add tests, so new features stop breaking old ones.
We harden login, sessions, roles and password reset, and fix Stripe subscriptions, webhooks and edge cases such as failed payments and plan changes.
We set up environments, CI/CD, backups, logging and monitoring on AWS, Vercel or Supabase, and fix performance so the app stays fast as data and users grow.
AI tools copy generic interfaces. We rethink flows, onboarding and the design system, and give your product a look that earns trust with users and investors.
You keep ownership of your code and your product. We work in your repository and explain every decision.
In 1–2 weeks we review the code, database, security, infrastructure and UX, and show you what is safe, what is risky and what it will take to fix.
Most AI-built MVPs do not need a full rewrite. We decide together what to keep, what to refactor and what to rebuild.
Security holes, data leaks and broken payments come first, before any new features.
We complete missing features, clean up the UX and UI and add tests, so the product is ready for real users.
We set up production hosting, monitoring and backups and stay with you through launch.
You get clean, documented code your team can work with, or we keep building with you as your product team.
Projects that show the level of design and engineering we bring to every product we take on.
We designed and built the SerenX website in-house, from first concept to production code. Before launch, SerenX shared it with around 100 prospective government customers and defense partners.

We used AI tools for images and video and built a scroll-based storyboard website in custom HTML and JavaScript, optimized so the cinematic experience stays smooth in the browser.

Together with Obriy Design Büro, we designed the product logic, UX and UI of an AI-native CRM that keeps complex sales funnels easy to work with.

We're not a freelancer who disappears after delivery. Not a 200-person agency where you'll never meet a senior. We're a boutique, embedded design team and the longer we work together, the sharper we get.
Remote-friendly team growing fast
We focus on quality over quantity
Sounds like your team?
Book a Discovery CallYou only need a quick one-line bug fix, a budget below $2,000, or someone to keep prompting the AI for you.
Every rescue starts with an audit. The audit starts at $2,000 and takes 1–2 weeks, depending on the size of the product and its backend. After the audit you get a fixed scope and estimate for the fixes, and hourly rates start at $50.
Usually not. Most AI-built MVPs have a lot worth keeping. We refactor what can be saved, rebuild only the parts that are unsafe or cannot scale, and explain every decision.
We work with apps built in Lovable, Bolt.new, v0, Replit, Cursor, Windsurf, Base44 and similar tools, usually on React or Next.js with Supabase, Firebase or Node.js on the backend.
Yes. We leave the code base in a state where you and your team can keep using AI tools safely, with tests, clear structure and documentation.
You do. We work in your repository and accounts, sign an NDA from the first call, and hand over everything at the end.
Yes. That is what makes Cosmos Studio different from pure development shops. Our senior designers rethink flows, onboarding and the design system, so the product is ready for real users and investors.
