MVP development for startups, from prototype to production
Built a prototype with an AI tool or a freelancer? We make it ready for real users: secure, tested, monitored and built to grow. Starting from an idea? We build the MVP properly from day one and launch it in weeks, not months.
Two Ways In
Founders reach us from one of two places. Each has its own first step.
You already have a prototype
You built it with Lovable, Bolt, Cursor or Replit, or a freelancer built it for you. Early users like it, and now it has to hold up under real users, real data, a security review or investor due diligence.
- Security, data access rules and tests fixed
- Monitoring, backups and a deploy you control
- Keep what works, refactor the risky parts
You are starting from an idea
You know the problem and the users, but there is no product yet. You want the MVP built properly from day one, so the version you validate is the one you grow.
- Scoped to the essential slice
- Security, tests and monitoring from day one
What Breaks When a Prototype Meets Real Users
Prototypes are built to prove an idea, not to hold real users’ data. Veracode’s 2025 GenAI Code Security Report found that AI-generated code introduced security flaws in 45% of its test cases. These are the gaps we look for first.
Auth and secrets handling
API keys sit in front-end code or the repo, sessions and password resets were never tested, and admin pages are open to anyone who finds them.
What we do: We move secrets server-side, rotate any that leaked, and put auth, sessions and roles on a proven library with tests around them.
Users seeing other users’ data
Database access rules are missing or too loose, so changing one ID in a request can return someone else’s records.
What we do: We write and test access rules for every table, so each query is scoped to the right user or team.
No tests, so every change is a gamble
Nothing checks the core flows, so fixing one screen quietly breaks another and you find out from a customer.
What we do: We add automated tests around sign-up, billing and your core workflow first, and run them on every change.
No logging, monitoring or backups
When something fails, a user tells you. There are no logs to show what happened and no tested way to restore lost data.
What we do: We add error tracking, logs, uptime alerts and automated backups, then test that a restore actually works.
An architecture that cannot grow
Everything runs in one place: no background jobs for slow work, no database migrations, and business logic scattered through the front end.
What we do: We move the risky parts into a proper backend with migrations and job queues, refactoring step by step instead of rewriting.
Unclear code ownership and lock-in
The code lives in someone else’s account, deployment depends on a single tool, and nobody can say who owns what.
What we do: We move the code into your repositories and cloud accounts and document how it deploys, so you can run it without us.
MVP Development Services
Hardening the prototype you already have, or building the first version properly from day one, with the same production checks either way.
Prototype Hardening & Takeover
We take over the app you built or a freelancer’s codebase and make it safe for real users: auth, secrets and data access rules fixed, tests around what works, and the risky parts refactored instead of starting over.
- Auth, sessions and tested data access rules
- Secrets moved server-side and rotated
- Tests, background jobs and migrations
- A documented deploy you control
MVP Scoping & Roadmap
We turn an idea into a tight, buildable first version (the smallest slice that tests your riskiest assumption) plus a roadmap for what comes after.
- Core problem and assumption mapping
- Must-have vs later feature cut
- Launchable v1 scope and roadmap
Web & Mobile MVPs
A launchable web app, or iOS and Android app, that real users can sign up for and use, built on a mainstream stack that holds up as you grow.
- Onboarding and the core user flow
- APIs, data model and auth
- Deployed and ready for real users
AI-Enabled MVP
An MVP with one genuinely useful AI capability built in (search, chat, drafting or automation), grounded in your data rather than bolted on.
- One core AI feature, done well
- Grounded in your own data
- Honest scoping of what AI can do
Launch, Run & Iterate
Once real users arrive, we iterate on what the data shows, keep dependencies and security current, and scale the parts that need it.
- Measure, learn and prioritize
- Improvements shipped in short cycles
- Dependencies and security kept current
Best Fit For
- founders with an AI-built or early-stage app heading into real users, a security review or investor due diligence
- founders validating a new idea who want the MVP built properly from day one
- teams that want scope cut to the essential slice instead of an oversized first version
- products that have to scale after launch, on code and infrastructure you own
Not the Right Fit When
- large builds with broad scope from day one, where a full product team is the better fit
- teams that want every feature in version one (that is the opposite of an MVP)
- throwaway experiments with no real users or data yet, where the AI builder alone is enough
- a cosmetic pass on a prototype when the real gaps are security and data access
For a larger build beyond a first version, see Product Engineering, or for a subscription product with tenants and billing, SaaS Development.
Keep Building in the AI Tool, Harden It, or Rebuild?
The honest version of the trade-off, so you only rebuild when hardening will not do.
Keep building in the AI tool
The fastest way to test flows and show an idea to early users, with no engineers involved.
Security, data access rules and tests are easy to skip, and each new change can quietly break something that worked yesterday.
Pick while you are still validating, before real users, real payments or real personal data are involved.
Harden what you have (what we do most)
Keeps everything users already like, fixes security, data rules, tests and monitoring, then refactors the risky parts.
Only works if the core data model is sound. The audit tells you whether it is before you spend on fixes.
Pick when the prototype works, users are arriving, and its structure can carry the next stage of the product.
Rebuild on a solid foundation
A clean architecture, data model and test suite sized for where the product is going, reusing the screens, flows and rules worth keeping.
Takes longer before users see a change, so it only makes sense when patching the prototype would cost more than replacing it.
Pick when the prototype’s structure cannot carry the product, or every fix breaks two other things.
Starting From an Idea? How We Build the MVP
The order matters: find the core problem and cut scope first, build with production checks from day one, then learn from real users.
Find the Core Problem
We pin down the real problem and the riskiest assumption to test: the one thing the MVP has to prove. Everything else waits.
Cut Scope to the Essential Slice
We cut to the smallest version that delivers real value to a real user. Fewer features, shipped, beat a big plan that never launches.
Build It Production-Ready
We build the slice with AI-assisted delivery, with auth, data access rules, tests and monitoring in from the first sprint.
Launch, Measure, Iterate
We launch to real users, watch how they behave, then build only the features that earn their place.
Start With a Production-Readiness Audit
A fixed-scope first step on the prototype you already have. You see what has to change before real users arrive, with a fixed estimate for the work, before you commit to more. Starting from an idea instead? We scope the essential slice and build the MVP with the same checks in from day one.
Production-Readiness Audit
We review the prototype you already have and tell you plainly what must be fixed before real users arrive, and what can wait.
- Security review of auth, secrets and data access rules
- Code, test and architecture review
- A fix list in priority order, and a launch plan
Fix & Launch
We work through the fix list in priority order, then launch with real users on a setup you can watch and roll back.
- Fix list worked through, riskiest items first
- Tests and monitoring in place
- Launch with real users
Run & Improve
Keep the product secure and moving as real usage shows you what to build next.
- Iterate on real usage
- Dependencies and security kept current
- Scale when the numbers call for it

Frequently Asked Questions
Straight answers to what founders ask us before taking a prototype to production or building an MVP.
Can you take over an app built with Lovable, Bolt, Cursor or Replit?
Yes. We take over apps that founders built in Lovable, Bolt, Cursor, Replit or v0, and codebases a freelancer handed over. We start with a Production-Readiness Audit of the code, the database and how logins and secrets are handled, then fix what matters most first. These apps are often a React front end on a hosted PostgreSQL database, a mainstream stack for our team, so we keep the parts that work instead of starting over.
What does a Production-Readiness Audit include?
It is a fixed-scope review of the prototype you already have. We check how authentication, secrets and database access rules are set up, review the code, test coverage and architecture, and hand you a prioritized fix list with a launch plan. You see exactly what has to change before real users arrive, with a fixed estimate for the work, and then decide whether we do it, your team does, or both.
What is an MVP?
An MVP, or minimum viable product, is the smallest version of a product that delivers real value to early users, enough to validate demand and learn from actual usage before investing in a full build. It is deliberately narrow but genuinely useful, focused on the single most important thing your users need. A prototype can prove the idea; an MVP also has to be safe for real users and their data.
How fast can you launch an MVP?
It depends on scope, and the scoping step ends with a fixed estimate. We keep it short by scoping the essential slice first: the one workflow that proves the idea, with everything else on a roadmap for later. For an existing prototype, the timeline depends on what the audit finds, and the fix list separates what must be done before launch from what can follow.
How do you keep MVP scope tight?
We start from the riskiest assumption the product needs to validate and cut everything that does not directly test it. During scoping we separate must-have-for-launch features from later-roadmap ones, push back on anything that can wait, and define a single clear first version. Shipping fewer features that work beats a large plan that never launches.
What drives the cost of an MVP?
Scope and starting point drive it. For a new MVP: the number of core workflows, how many third-party systems you integrate, web only or web and mobile, the depth of any AI feature, and how much custom design the first version needs. For an existing prototype: how much of the code can be kept, how sensitive the data is, and how far the security and data access fixes reach. Keeping the first version tight is the most effective way to control both cost and time, and the audit or scoping step ends with a fixed estimate.
Do you use AI to write code too?
Yes. Our engineers use AI tools for scaffolding, code generation, tests and review, which shortens delivery. Every change still goes through an experienced engineer’s review and automated tests before it reaches your users, because unreviewed AI-written code is exactly the problem a prototype runs into when real users arrive.
Is the code ours?
Yes. You own all source code and intellectual property we produce, committed to your repositories as we build, with no lock-in, so you can bring the work in-house or move to another team at any time. If your prototype depends on a hosted builder today, we map what it takes to move it onto infrastructure you own.
