Custom AI Development

Bespoke AI models, API integrations and custom pipelines tailored exactly to your specific business needs — when off-the-shelf solutions don't cut it. Price: €3,000–20,000.

What is custom AI development?

Custom AI development is the creation of bespoke AI solutions built from scratch or on top of existing infrastructure. Unlike standard platforms (Make, n8n, chatbot builders), custom development delivers exactly what your business needs.

Custom development is typically chosen when business requirements are too complex for no-code tools, data is sensitive and cannot flow through third-party platforms, or maximum accuracy for a specific domain is required.

What solutions do we build?

Custom AI agents

LangChain or custom-built AI agents that autonomously perform multi-step processes — browse, analyse, make decisions — without human intervention.

Domain-specific models

AI models trained on your industry data — medical diagnostics, legal document analysis, financial forecasting — tuned for maximum accuracy.

Legacy system integrations

An AI layer that bridges modern AI tools with old ERP/CRM systems that lack modern APIs — no need to replace existing infrastructure.

Custom NLP solutions

Text classification, sentiment analysis, information extraction from unstructured text — built to your specific schema and requirements.

Computer vision and image analysis

Visual solutions: product quality control, anomaly detection, automated inventory counting from photos or video feeds.

Recommendation engines

Custom recommendation algorithms for e-commerce, content platforms, or SaaS products — personalised based on user behaviour.

Frequently asked questions

How much does custom AI development cost?+

API integration + custom logic — €3,000–6,000. Custom AI agent — €6,000–12,000. ML model with deployment — €12,000–20,000. Support — €500–1,500/month.

When should I choose custom development over platforms?+

Custom development is right when standard tools don't provide the required accuracy, data is sensitive and can't go through third parties, deep integration with legacy systems is needed, or the process logic is genuinely unique.

How is an AI developer different from a regular developer?+

AI developers have specialist skills: ML/DL fundamentals, LLM APIs (OpenAI, Anthropic, Google), vector databases, prompt engineering, and AI agent architecture. Not every backend dev has this knowledge.

How long does custom AI development take?+

Simple project — 3–5 weeks. Mid-size — 6–10 weeks. Complex with ML models and deployment — 10–20 weeks. Exact timeline depends on requirements complexity.
