Cord of Three

Vibe-code with velocity. Launch with security.

AI gives you the speed to build. We provide the architecture to make it scale.

OUR PHILOSOPHY

Three strands of resilient software

Vision

Founder and domain expertise

You understand the product and the market. You know what the needs are, and you want to focus your time on users and customers, not infrastructure.

Velocity

AI code generation

AI models write code at unprecedented speeds. They give you the velocity to experiment and ship features in hours, not months.

Guardrails

Architecture and governance

We provide the third strand. We build the engineering guardrails, secure credential vaults, and automated verification pipelines you need to scale safely.

OUR SERVICES

Engineering guardrails

Fixed-scope engineering services designed to fit your workflow. We offer point-in-time security audits, automated interlock pipelines, and ongoing retainers.

Tier 1

Point-in-time audit

$1,499 / flat fee

A comprehensive audit of your codebase to locate and resolve critical vulnerabilities.

  • 01.
    Secrets and keysAuditing credentials, access tokens, and API key management.
  • 02.
    Logic and accessEnsuring strict isolation between user accounts and database collections.
  • 03.
    Dependency integrityDetecting and removing hallucinated or corrupted packages.

Tier 2

Continuous guardrails

$3,999 / setup

Implementation of a security interlock pipeline to permanently safeguard your codebase.

  • 01.
    CI/CD pipelineAutomated GitHub Actions workflow for pull request security checks.
  • 02.
    LLM gatekeeperAI-powered architectural review enforced before any merge.
  • 03.

Tier 3

Fractional CTO retainer

$5,000 / month

Strategic architecture, prompt-rot intervention, and security governance. Ideal for funded teams needing senior oversight without hiring full-time developers.

  • 01.
    Fractional CTO supportDedicated advisory hours to guide your architecture, review B2B questionnaires, and design system boundaries.
  • 02.
    Prompt-loop interventionDirect Slack communication when your AI models hit a wall, get caught in loops, or output conflicting logic.
  • 03.
    Security governanceContinuous checks of database rules, deployment credentials, and key safety as your application grows.

Not sure which tier matches your current stage? Answer a few questions about your product, and we will calculate the right service strand for your needs.

Configure Strategy

Select your app's current stage and primary engineering concern to view recommended guardrails.

Recommendation Reason:At the MVP stage, your primary goal is to validate your product quickly without introducing critical liabilities. A point-in-time audit provides a baseline security check on your codebase, allowing you to find, prioritize, and mitigate vulnerabilities before exposing your app to the public.
