# Stack3 Labs

> Stack3 Labs is a production engineering studio that rescues vibe-coded prototypes built with Lovable, Cursor, Bolt, v0, Replit and Claude Code, and ships them to production in 30 days — fixed price, fixed scope, live in 30 days.

## About
- Positioning: We finish what AI coding tools start. We do not compete with Lovable, Cursor, Bolt or v0 — we come in after them.
- Tagline: You vibe-coded it. We make it real.
- Service area: United States and Canada (primary), global remote.
- Delivery: Senior LATAM engineers working in US time zones.
- Code ownership: Clients own 100% of the code, the repo and every credential from day one.
- Equity policy: No equity. Vendor partner only.
- Capacity: 2 rescues per month. When the calendar is full, founders join the waitlist or get a vetted referral.

## Who we serve (ICP)
- **Primary ICP**: Pre-seed or self-funded founders ($200K–$1.5M raised or $30K–$80K of personal runway) who shipped a prototype with an AI coding tool (Lovable, Cursor, Bolt, v0, Replit, Claude Code) and need to get to production in weeks, not months. Prototype is typically 50%+ done. They are non-technical or semi-technical, have no CTO, will not trade equity for engineering, and are stuck on deploys, auth, Stripe, Supabase RLS or AI features in production.
- **Not a fit**: founders without a prototype yet; native mobile / hardware / DeFi / token-launch projects; founders shopping for the cheapest hourly rate; pure design or branding work.

## What we fix
- Stripe webhooks that fire twice or never; ghost subscriptions; missing receipts
- Auth sessions that leak, password reset that never arrives, OAuth that drops state
- AI agents that hallucinate, leak system prompts, loop forever or refuse easy answers in front of paying users
- Supabase RLS holes, missing grants, schema drift, no backups
- Deploys that break randomly with no logs, no error tracking, no monitoring
- AI coding tools that have hit their ceiling and now break more than they fix

## Our four engagements

### Vibe Code Audit — Free (48-hour turnaround)
A senior engineer reviews your repo, database and deploy path. You receive a Loom walkthrough of every production gap (auth, payments, AI, infra, security, observability) and a written 30-day plan that ranks issues by risk and effort. Yours to keep even if you never hire us. No pitch. No sales theater.

### 30-Day Rescue & Launch — Fixed price, live in 30 days
- **Lite — $14,997**: Prototype 50%+ done. Hardening of auth, payments and deploy. 1 AI feature with evals + guardrails. Up to 5 user flows. 30 days of Stewardship included.
- **Standard — $24,997** (most popular): Full hardening + missing features. Up to 2 AI features. Up to 10 user flows. Complete observability. Investor-ready demo video at launch. 30 days of Stewardship included.
- **Pro — $39,997**: Rebuild of fragile pieces + significant new scope. Multi-agent or advanced RAG. Up to 15 polished flows. Load tested to 1K concurrent. White-glove handoff.

### Stewardship — Post-launch monthly care

- **Care — $2,997/mo**: Everything in Watch + 15h/mo of dev work (features, perf, AI prompt iteration) + AI change review before risky changes hit production.

### Evolution Retainer — Productized engineering retainer
- **Pod 1 — $8,997/mo**: 1 dedicated senior engineer with AI tooling leverage. Weekly demo + async standup. Direct Slack channel.
- **Pod 2 — $14,997/mo** (most popular): 2 dedicated senior engineers + part-time PM. Weekly demo + sprint planning.
