# Internet Engineering | Software Agency for Founders

> Internet Engineering is a software agency for founders that designs and ships complete products: brand, web, mobile, and agentic AI. Netherlands-based, working worldwide.

## What Internet Engineering does

Internet Engineering turns ideas into complete products: brand identity, web apps, mobile apps, and agentic AI. We also rescue vibe-coded and AI-generated prototypes and harden them into production software you can sell. Engagements are flat-fee projects or monthly partnerships from EUR 2,000. Email hello@internet-engineering.com to start.

## When to hire Internet Engineering

- You have an idea and nothing else. We take it from there: brand, product, web, mobile, and AI.
- You vibe-coded an app that will not survive real users. We keep what works, and harden the rest into production.
- Your product needs AI that actually works. We ship agents and MCP integrations we already run ourselves.

## Selected work

- [Vesselspro](https://internet-engineering.com/case-studies/maritime-saas-development): Internet Engineering built Vesselspro as a maritime SaaS platform on Next.js with fleet tracking, cargo and crew workflows, AIS ingestion via a Bun/Elysia service, Drizzle on Neon, Better Auth, and companion iOS and Android apps.
- [Integrate](https://internet-engineering.com/case-studies/mcp-api-integration-development): Internet Engineering built Integrate so developers connect GitHub, Gmail, Slack, Linear, and more to AI agents through MCP with a TypeScript SDK, Go MCP server, OAuth PKCE, and less than 20 lines of setup for frameworks like the Vercel AI SDK.
- [aiassure](https://internet-engineering.com/case-studies/financial-due-diligence-saas-development): Internet Engineering built aiassure as a multi-tenant financial due diligence workspace where CPAs run QoE, working capital, concentration, tax, and legal modules with deterministic calculations, audited mutations, and an AI deal copilot that accelerates extraction and review without replacing sign-off.
- [Individu](https://internet-engineering.com/case-studies/agentic-ai-saas-development): Internet Engineering builds Individu as an agentic AI SaaS where users delegate work across connected apps, using Next.js, AI SDK (Bedrock), structured json-render responses, Better Auth, Drizzle, and native desktop and mobile wrappers.

## FAQ

### What does Internet Engineering do?

Internet Engineering designs and builds complete software products for founders: brand identity, web apps, mobile apps, e-commerce, and agentic AI features. One team covers strategy, design, engineering, and launch, so your product ships as one coherent ecosystem instead of disconnected parts.

### Can Internet Engineering fix my vibe-coded or AI-generated app?

Yes. We audit AI-built and vibe-coded prototypes, keep what works, and rebuild what doesn't: architecture, security, performance, and design. You keep your momentum and validation; we make it production-ready and maintainable so it can grow into a real business.

### Who should hire Internet Engineering?

Founders and product teams who want a senior partner, not a ticket queue. Typical clients are launching a new product, adding agentic AI or integrations to an existing one, or turning a fragile MVP into software they can sell and scale.

### Does Internet Engineering build AI software?

Yes. We build agentic AI products and features using the Vercel AI SDK, MCP servers, and modern model providers. We created Individu and Integrate in-house, so the AI patterns we ship for clients are ones we run in production ourselves.

### How much does it cost to work with Internet Engineering?

Scoped projects are quoted as a flat fee after a free discovery conversation. Ongoing product partnerships start from EUR 2,000 per month. Email hello@internet-engineering.com for a free, no-obligation estimate.

### How fast can Internet Engineering ship a product?

In the AI era, a branded, working product across web and mobile can go from idea to first release in weeks, not quarters. Speed never replaces discipline: everything we ship includes real architecture, testing, deployment, and handover.

### Where is Internet Engineering based?

Internet Engineering is registered in the Netherlands (KVK 97860891, VAT NL005293287B03) and works with founders across Europe and worldwide in English.
