6-12 Week Sprint
Prototype-to-MVP Sprint
From clickable to chargeable.
Take a prototype to first paying users in six to twelve weeks. Real payments. Real users. Real ops.
Fixed price, set once we scope it over email. A simpler build costs less, a more complex one more.
You have a prototype. People love it. Investors are nodding. Users want it. Now you need it to actually work for real users: payments, error handling, abuse protection, monitoring, an admin tool to manage the chaos of real customers, and a way to actually get paid. That is a different sprint, and it is where most prototypes die because the founder does not know what to ask for.
In six to twelve weeks (depending on scope) you walk away with production-ready software your first 100 users can actually use. Stripe wired in. Errors monitored. Admins can see what is happening. The code is on a standard stack your next hire can maintain. The prototype becomes a real product.
I run this exact production stack on my own product: Fitly AI ships with Stripe billing, monitoring, an admin dashboard, and a ten-layer AI orchestration engine, built and operated by one engineer. Read the case study to see what production-ready looks like.
How it breaks down
What happens
Auth, error handling, monitoring, security baseline
Take the prototype from "works on the happy path" to "does not break when a real user hits it." Robust auth, error boundaries, structured logging, exception monitoring, security baseline against OWASP Top 10.
Payments, onboarding, transactional email
Stripe integration with webhooks and subscription handling. User onboarding flow that actually converts. Transactional email for signup, billing, password reset, and account events.
Admin dashboard, analytics, alerts
Admin tool so you can manage users, payments, and customer issues without filing tickets with me. Analytics that tell you what users are actually doing. Alerts for the conditions that should wake someone up at 3am.
Load testing, beta cohort, feature flags
Optional final weeks if scope warrants: load testing against realistic traffic, beta cohort onboarding tooling, feature flag system for safe rollouts.
Deliverables
What you walk away with
Production-ready application
Deployed, monitored, and ready for real paying users. Standard stack on standard infrastructure. Documented runbooks for the operational stuff: deploys, rollbacks, incident response.
Stripe payments wired and tested
Subscription billing, one-time charges, webhooks, dunning, invoices. Tested end-to-end against Stripe test mode. Real money handling that you can actually trust.
Admin dashboard
A view into what users are doing, what they are paying, and where they are getting stuck. You manage your own product without filing tickets with me for every customer issue.
Monitoring and alerts
Errors caught and surfaced. Uptime tracked. Key business metrics on a dashboard. Alerts for the conditions that actually need a human at 3am, and silence for the ones that do not.
Also included
- Deploy automation: push to main, ships to staging, promotes to prod
- Documented runbooks for common operational tasks
- Updated README with environment setup, secrets, and architecture notes
- Written handoff plus a live demo over Zoom covering ops, monitoring, and what to watch in the first 30 days
- 30-day post-launch bug-fix support window
Who it's for
This sprint is built for
Founders who finished a prototype and need it to handle real users
Companies validating a new product line and ready to start charging
Anyone whose prototype is generating real interest and they want to capture it before momentum dies
Teams who want one senior engineer to take the prototype to launch, not an agency

Agentic AI is the leverage
Hardening a prototype to MVP is mostly known patterns: auth flows, payment flows, admin patterns, monitoring patterns. Agents implement these in parallel against my specs. I review, harden, and verify each one. What used to be six months of agency work compresses to six to twelve weeks of focused engineering.
What I do vs. what agents do: Same product development cycle I have always run, just 100x faster on the build step. Agents implement; I review and QA every update. I make every architecture call, every security trade-off, every product decision. The iteration speed is what changes: I can refactor a flow, ship a new approach, and validate it in a day instead of a sprint.
AI stack used in this sprint
To get started quickly
What I need from you
- Working prototype (yours, or one I built in the Idea-to-Prototype Sprint)
- Decisions on billing model: subscription, usage-based, or one-time
- Stripe account, or willingness to set one up
- Domain you want to launch on
- Branding and design preferences (we can use what is in the prototype if you do not have changes)
After the sprint
Two paths from here
Hand it off
Run with it. The code is yours, on a standard stack, with documented runbooks. Your next hire can maintain it. No retainer needed.
Keep me on
Stay on as your Fractional CTO. I keep iterating on features with you, help you scope and ship the next thing, and help you hire and structure your engineering team when the timing is right. Monthly retainer, cancel anytime.
