A working prototype proves the concept. Production-grade software serves real customers.
The gap between a prototype and a production application is wider than it looks: error handling, security, performance at load, authentication, billing, observability, and the dozens of edge cases the prototype ignores. We build the production application your prototype was a sketch of. Fixed scope, fixed price.
A working prototype that proves the concept but lacks the error handling, security, performance, and billing infrastructure required for real customers
Prototypes are built to answer a question: "Does this idea work?" They're built fast, they cut corners, and they're not meant to be extended. A prototype that successfully answers the question creates a new problem: the business is ready to move, but the prototype can't carry it.
The specific gaps between a prototype and a production application:
No real authentication: The prototype uses a single hardcoded account, or implements authentication so basically that it wouldn't survive a security review.
No error handling: When something goes wrong in the prototype, it either crashes silently or shows a raw error message. Production applications handle every error state gracefully.
No billing: The prototype demonstrates the product. It has no mechanism for collecting payment.
No multi-tenancy: The prototype was built for one user. Production applications serve many isolated customers.
No observability: When something goes wrong in the prototype in production, there's no way to know what happened.
Performance debt: The prototype was never tested with real data volumes. The first 1,000 real customer records reveal query performance issues that didn't exist in the prototype.
Security vulnerabilities: The prototype was built to demonstrate functionality. Security wasn't a consideration.

Architecture rethink
The prototype's data model is reviewed before a single production line of code is written. The production data model is designed for the use cases the prototype revealed — not the use cases the prototype assumed.
Authentication via Clerk
Proper multi-user authentication replacing whatever the prototype used. Multi-tenancy if the product requires it.
Stripe billing
Subscription management, free trial, or one-time payment — whatever the product's billing model requires.
Error handling throughout
Every async operation has error handling. Every UI state that can fail shows appropriate error feedback. No raw stack traces in production.
Observability
Sentry for error monitoring. Vercel Analytics for performance monitoring. Alerting on error rate increases.
Security baseline
The OWASP Top 10 reviewed against the production implementation. API authorization checks on every endpoint. Dependency security audit.
One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
The scope of a prototype-to-production project is defined by the prototype: the features that exist, the gaps that need to be filled, and the infrastructure that needs to be added. Fixed price after the prototype review.

Questions, answered.
If the prototype was built in the same stack (Next.js, React), selected modules may be usable as a starting point. More often, the prototype's shortcuts create technical debt that's faster to rewrite than to fix. The decision is made prototype review — not assumed upfront.
An MVP is a minimum viable product — built from scratch to the minimum quality bar for real customer use. A prototype-to-production project takes an existing prototype concept and builds it to production quality. The output is similar; the starting point is different.
Prototype-to-production project: from $25k. Larger prototypes with complex feature sets: from $45k. Fixed-price.
