API development & AI integrations
Plugging AI into a product already in production, without starting over: that's the heart of enterprise AI integration. OpenAI and Anthropic connection, custom API development, RAG and embeddings wired to your existing data, from prototype to production in under two weeks.
How do you integrate AI into a company without technical debt?
Enterprise AI integration means wiring artificial intelligence into your tools and data so it serves your teams every day, not stays stuck in a demo. We connect major language models (OpenAI, Anthropic, Mistral) and the AI services you already adopt (ElevenLabs, HeyGen, Cursor…) to your CRM, your applications or your internal processes, through clear, lasting custom API development. You get concrete features, controlled costs, and the ability to grow your stack over time without rebuilding everything.
Why does AI stay in demo instead of serving your teams?
Your data, your processes and your third-party services aren't connected to artificial intelligence. Without API integration, AI stays a demo, never wired into what actually runs your business.
AI disconnected from your data
CRM, ERP, internal docs, customer databases: without API integration, models can't see your context. AI can't enrich your products or inform your decisions.
Processes still manual
Summaries, follow-ups, routing, updates between tools: your teams bridge the gaps by hand. Every manual step slows the business and multiplies errors.
Isolated AI services
OpenAI, ElevenLabs, HeyGen, business tools: each in its own corner, with no bridge to your app or workflows. You're paying for APIs that nobody actually uses day to day.
A reliable, measurable, lasting AI API integration
We build a custom API development layer and wrap every AI call with guardrails, cost tracking and fallback. No magic: maintainable code your teams can take over.
We start from the concrete use case
No AI integration for its own sake. We identify where it actually unlocks measurable ROI.
Clean, scalable architecture
A single API integration layer, clear contracts, end-to-end observability.
Costs and quality monitored
Tokens consumed, latency, error rate: everything instrumented from day one.
Enterprise AI integration wired in, measured, scalable
We go beyond the POC: your product actually uses AI in production, at controlled cost and without accumulated technical debt.
From POC to production
We industrialize your demo: tests, monitoring, error handling, automatic scaling.
Controlled API costs
Per-user quotas, caching, the right model for each case: the bill follows the value delivered.
Interchangeable providers
An abstraction layer: we switch from OpenAI to Anthropic or Mistral without rewriting the custom AI API integration.
GDPR compliance ensured
Sensitive data, anonymization, European hosting if needed: compliance is scoped from the start.

Contact usWe first identify the use case with the fastest ROI, then build a custom API layer that connects the chosen model (OpenAI, Anthropic, Mistral) to your existing systems. Enterprise AI integration doesn't require rebuilding everything: 80% of projects plug AI into a product already in production in under two weeks.
Custom AI API integration means building a software layer that connects an LLM (OpenAI GPT-4o, Claude, Mistral) or third-party AI services (ElevenLabs, HeyGen, Gemini…) to your infrastructure: database, CRM, ERP or existing application. The goal: enrich a product already in production with new use cases, voice synthesis, content generation, automation, without rebuilding everything. It includes credential management, cost tracking, error handling and the ability to switch providers if needed.
The development depends on the complexity of the API integration: a simple OpenAI connection takes one to two weeks, a full RAG project four to eight weeks. The recurring cost depends on the token volume: we estimate it upfront and optimize it after launch through caching, model choice and batching.
Not necessarily. We can route via Azure OpenAI, Anthropic Bedrock or host an open-source model on your infrastructure. For sensitive data, we scope GDPR compliance and European hosting from the start.
Models evolve, prices drop, more powerful new versions come out regularly. We handle the follow-up and migrate when it's worthwhile, without you having to manage the dependencies yourself.
