AI CTO as a Service: GenAI, Multi-Agent & RAG Expertise to Accelerate Your Transformation

AI CTO as a Service: Strategic and Technical Expertise On-Demand

Our CTO as a Service provides access to C-suite level expertise in generative artificial intelligence, multi-agent systems, RAG (Retrieval-Augmented Generation), and AI digital transformation — without the constraints of permanent recruitment.

What is an AI-Specialized CTO as a Service?

An AI CTO as a Service is a senior externalized technical director who:

• Defines your AI strategy aligned with your business objectives and product roadmap
• Leads your GenAI projects end-to-end: multi-agent systems, intelligent chatbots, RAG automation
• Selects and optimizes your tech stack (LLMs, frameworks, cloud infrastructure)
• Scales your technical teams by recruiting, training and leading your AI developers
• Manages your tech ecosystem (vendors, offshore providers, technology partners)
• Optimizes your R&D costs via CIR/CII schemes (Research & Innovation Tax Credits)

Unlike a traditional consultant who delivers a report then disappears, our CTO as a Service integrates into your organization and takes operational responsibility for your AI initiatives.

GenAI, Multi-Agent and RAG Expertise at the Core of Our Offering

Multi-Agent Systems: AI That Acts, Not Just Responds

Multi-agent systems represent the major evolution of 2025. Unlike basic chatbots, these AI agents:

• Plan their actions to achieve complex objectives
• Use tools (APIs, databases, web search) autonomously
• Collaborate with each other to solve multi-step business problems
• Continuously improve through reinforcement learning

Concrete use cases:

• Customer support agent that analyzes context, consults technical documentation, and proposes personalized solutions
• Sales prospecting agent that identifies qualified leads, enriches CRM data, and generates personalized emails
• Compliance validation agent that automatically verifies regulatory compliance by cross-referencing contracts, laws and operations

Enterprise RAG Architecture: Transform Your Data into Competitive Advantage

RAG (Retrieval-Augmented Generation) allows your LLMs to leverage your proprietary data to generate accurate and contextualized responses, without hallucinations.

Our RAG expertise covers:

• Intelligent vectorization of your documents (250+ employees, millions of pages)
• Optimized Elasticsearch architecture with high-availability clusters
• Custom embeddings for ultra-precise semantic search
• Commercial proposal generation systems powered by your business knowledge
• Multilingual conversational chatbots with contextual memory

Result: Your teams instantly access the company's collective knowledge via a conversational interface, with 95%+ accuracy.

FAQ: AI CTO as a Service

What's the difference between a CTO as a Service and an AI consultant?

An AI consultant analyzes your situation and delivers recommendations. A CTO as a Service takes operational responsibility for your AI projects: pilots, recruits, manages, codes, deploys and optimizes.

How long does it take to see results?

We target a Quick Win in production within 30 days. Deep transformations (multi-agent systems, enterprise RAG) generally take 3-6 months to reach full maturity.

Does my current technical team need to be replaced?

Absolutely not. Our role is to train, supervise and upskill your existing teams. We only recruit complementary profiles if necessary.

What happens if I want to stop the collaboration?

Our commitments are flexible (monthly or quarterly depending on option). You can adjust or stop with one month's notice. All code and documentation belong to you.

Will AI replace my employees?

AI augments your employees' capabilities, it doesn't replace them. Our systems aim to eliminate repetitive and time-consuming tasks so your teams can focus on high-value activities.

How do you handle our data confidentiality?

We sign strict NDAs and apply security best practices (GDPR, ISO 27001). Your data is never shared with public LLMs without your explicit consent.

Can you work with our existing technical providers?

Yes, we're used to coordinating complex ecosystems of providers, agencies and technology partners. Our role is to orchestrate and align everyone.

What's the minimum company size for this service?

We primarily work with SMEs from 20 employees and mid-sized companies up to 2000+ employees. The key criterion isn't size but AI transformation ambition.
