Full-stack product work, senior-only.

When you need to ship product, not just AI features. Next.js, TypeScript, Postgres, everything modern. We plug into your team or run the engineering end-to-end. No juniors on client work.

Make your AI cheap enough to ship at scale.

LLM cost optimization, inference caching, eval pipelines, vector DB tuning, observability. The unsexy work that makes the difference between a demo and a production feature.

// Why VertCode

The AI team you'd hire if you could.

Production, not proofs-of-concept

Every AI feature we ship runs in production at scale. Users at that scale don't care about your demo. Neither do we.

Senior-led engagements

Every project is architected and reviewed by an engineer who has shipped production systems at 7M+ user scale. Our full team executes, never juniors left unsupervised.

Transparent cost and timeline

Fixed-scope proposals with real delivery dates. No hourly games. No 'AI is hard' excuses. Shipped in weeks, not quarters.

We don't sell AI. We ship systems that happen to use AI. The difference matters in production.

// FAQ

Questions founders ask us.

Why hire you instead of hiring an in-house AI engineer?

Senior LLM engineers in the US take 4-6 months to hire and cost $250k+ loaded. You can have us shipping your AI feature in under two weeks. When you're ready to hire in-house, we hand off cleanly.

Do you work with companies outside Europe?

We're an EU company. Most of our clients and partners are US-based, and we operate with overlap on US East Coast hours. Most of our delivery is async, which works well across time zones.

How do you price projects?

Fixed-scope fixed-price for defined work. Monthly retainer for ongoing engineering. No hourly billing. You'll know the number before we start.

What's the smallest engagement you take?

A two-week paid architecture and feasibility sprint. We deliver a technical spec, cost model, and working prototype. From there, you decide whether we build the full thing.

What industries do you work in?

B2B SaaS is our focus. We've shipped at scale in EdTech and gaming analytics. We don't take on EdTech competitors, healthcare (HIPAA complexity), or crypto.

// Let's work together

Tell us what
you're shipping.

We take on a small number of clients each quarter. If you're a SaaS company that needs to ship AI features, or you've started and gotten stuck, tell us what you're working on. We usually reply within 24 hours with a concrete next step.
