Vibe Coding for Startups: AI-Native Development with Security Built In
Ship production platforms using Cursor, Claude Code, and MCP workflows with security testing built in from day one. We apply 15 years of production engineering to AI-assisted development so you iterate faster without accumulating security debt.
Most teams vibe code prototypes, then rewrite everything for production. We ship production-grade platforms on the first pass-Next.js with auth, billing, monitoring, and security testing-because the LLM handles boilerplate while we architect guardrails, test harnesses, and deployment pipelines.

Ship your AI platform in weeks, not months
Share your MVP requirements in a 30-minute session. I’ll map AI-assisted development workflows, security checkpoints, testing automation, and deployment architecture-so you know exactly what we can vibe code safely and what requires traditional review.
What is vibe coding?
Practical explanation for founders
Vibe coding means using AI assistants (Cursor, Claude Code, IntelliJ IDEA Ultimate + Codex) to generate boilerplate, scaffold features, and accelerate implementation-while you focus on architecture, security, and business logic. It's not “let the AI write everything.” It's pairing deep production experience with LLM-powered acceleration to ship faster without cutting corners.
When you should vibe code
- You're building a greenfield MVP on modern stacks (Next.js, TypeScript, Supabase).
- You need rapid iteration with investor demos every 2-4 weeks.
- Your team has production experience but wants 10x faster scaffolding.
- You're comfortable with automated testing and security reviews.
When you should NOT vibe code
- You're working on legacy codebases (Rails 4, Drupal 7, Java EE).
- You need formal compliance audits without dedicated security review capacity.
- Your team lacks production engineering experience to review generated code.
- You're building life-critical systems (medical devices, flight control).
Use cases we build
Why production expertise matters with vibe coding
AI coding tools like Cursor make implementation accessible to everyone. But implementation isn't the hard part—architecture, security, and scale patterns are. Here's what we've learned from shipping production platforms using vibe coding.
Vibe coding tools democratize implementation, not expertise. LLMs generate clean code for single features, but they don’t architect auth boundaries, design multi-tenant data isolation, or prevent the subtle bugs that compound into security incidents months later.
Security gaps you won't see until audit
Cursor generates auth middleware that looks secure but leaks tenant data through missing RLS policies. You ship to 10 customers before discovering User A can query User B's records. Fixing this post-launch costs 10x more than architecting it correctly from day one.
Production patterns LLMs don't know
AI generates database queries without indexes, API calls without rate limiting, and background jobs without dead-letter queues. Your MVP works fine at 10 users. At 1,000 users, PostgreSQL melts down and you’re debugging prod at 2am because the LLM never learned about connection pooling.
Investor diligence failures
Series A investors hire security firms to audit your platform. They find hardcoded API keys, missing audit logs, and SQL injection vectors—all from vibe-coded features that “worked” in demos. The round stalls for 8 weeks while you remediate findings that shouldn't exist.
Technical debt that compounds
Every vibe-coded feature without tests creates debt. Six months in, you can't add new features without breaking existing ones. Regression bugs slip through because nobody architected a test harness. You spend more time fixing bugs than shipping features—exactly what vibe coding was supposed to prevent.
Cost overruns from rework
Rebuilding auth, migrating to proper multi-tenant architecture, and adding observability post-launch costs multiples more than doing it right initially. Bringing in a senior engineer later means full-time compensation, onboarding, and lost time. Our 8-week engagement bakes in security so you keep velocity and own the IP.
Unreliable systems lose customers
Your vibe-coded platform crashes during a customer demo because the AI didn't implement circuit breakers for third-party APIs. You lose the deal. It happens again, and the “cheap” DIY approach turns into hundreds of thousands in lost pipeline and churned revenue.
The real choice
DIY vibe coding
- Learn production patterns by making mistakes
- Discover security gaps during investor diligence
- Rebuild features when architecture doesn't scale
- Spend time debugging instead of talking to customers
Best for: founders with 6-12 months to learn production engineering while building.
Expert-led vibe coding
- Ship with security architecture from day one
- Pass investor diligence without remediation cycles
- Automated testing prevents regressions
- Focus on customers while we handle infrastructure
Best for: founders who need to ship fast without cutting corners on security.
We compress 15 years of production mistakes into an 8-12 week engagement. You can absolutely learn this yourself—but the tuition costs more than hiring someone who's already made (and fixed) these mistakes.
How Security-First Vibe Coding Works
Most teams vibe code MVPs, then panic when security reviews find issues. We wire testing, observability, and security checkpoints into the development workflow-so audits pass on the first attempt.
Production-Grade Vibe Coding Stack
We use AI assistants to accelerate implementation, but the stack underneath is battle-tested production infrastructure-not experimental frameworks.

Engagement flow
- 1. Feasibility assessment. Review requirements, stack preferences, and security needs. Determine what to vibe code vs. manually architect.
- 2. Security scaffolding. Set up auth boundaries, data isolation, logging, and test harnesses before feature development.
- 3. Vibe coding sprints. Use Cursor/Claude Code to implement features with automated testing and code review on every commit.
- 4. Hardening & launch. Penetration testing, load testing, documentation, and staged rollout to production.
What you get
- Production-ready Next.js platform with auth, billing, and AI features.
- 800+ automated tests (E2E, unit, integration) for regression safety.
- Penetration test report showing security posture before launch.
- PostHog dashboards tracking adoption, performance, and costs.
- Deployment pipeline with preview environments and rollback procedures.
- Handover documentation and runbooks for your team.
- Simple MVP (auth + core feature): 3-4 weeks including security review.
- Multi-tenant SaaS with AI: 6-8 weeks including RAG, billing, and pen testing.
- Platform migration: 8-12 weeks depending on codebase size and complexity.
- Internal tools: 2-4 weeks for single-tenant applications with SSO.
Timelines assume clear requirements and stakeholder availability for weekly reviews. Complex integrations or compliance requirements may extend schedules.
Vibe Coding Security Architecture
The risk with vibe coding isn't the AI-it's shipping generated code without verification. We add security checkpoints at every stage so fast iteration doesn't create vulnerabilities.
