Custom AI Development

Custom AI builds for when off-the-shelf isn't enough.

We design and ship production AI software, RAG systems, knowledge bases, and custom ML models in 8–16 weeks, for mid-market teams across Europe and the US who've outgrown what they can buy.

How we build

Three things that make it production-grade.

01

Data Foundation

We architect retrieval, embeddings, and access controls so the system has the right context to draw from.

02

Production Engineering

Logging, evals, retries, and monitoring built in, so it holds up under real load.

03

Handover

Full code, documentation, runbooks, and test suites, your team owns and runs it.

  1. 01

    Scope

    1–2 weeks

    A fixed-price proposal with a clear timeline, written against your data and stack.

  2. 02

    Design

    2–4 weeks

    We architect retrieval, model, and API, then prove a working prototype before we scale it.

  3. 03

    Build

    4–10 weeks

    Production-ready code with evals, monitoring, and retries, engineered to hold up.

  4. 04

    Handover

    1 week

    Full code, documentation, runbooks, and training. Your team owns and runs it.

What we build

Systems built for your data and stack.

From retrieval to bespoke models, production software, not prototypes.

RAG Systems

Search and chat over your private data, documents, support tickets, contracts, code, anything text-based.

Enterprise Knowledge Base

A single source of truth your team can query in plain language.

Custom ML Models

Classification, prediction, scoring, and ranking, trained on your data.

Production AI Agents

Autonomous systems that take action across your stack.

AI-Powered Pipelines

Bulk processing, classification, enrichment, and routing at scale.

Axel Dekker, founder of What's Next

Ship the AI build your team can't.

Bring the problem off-the-shelf tools can't solve. We'll scope it in weeks.
