AI integration

Useful AI, wired into your business.

We design concrete AI tools connected to your data and existing software: private RAG, business assistants, tool-using agents, conversational analytics and production guardrails.

  • ROI-led use cases

    We prioritize workflows where AI truly improves productivity, quality or customer experience.

  • Private RAG on your data

    Docs, tickets, code and procedures become reliable, cited and traceable answers.

  • Agents connected to tools

    Assistants can create, qualify, summarize or check with audit logs and human validation.

  • Production & governance

    Evals, permissions, latency, cost, security and guardrails are designed before launch.

Word of mouth

Founders, CTOs and VPs on what changed.

Real partners, real platforms in production.

  • It was a real pleasure working with Bluesquare. The team was very reactive and close to our needs. We have been able to implement a sleek and easy to use co-mentoring platform in record time.

  • As an investment firm, we’re often looking for independent experts that can perform a quick due diligence on the digital products or softwares of the startups we’re investigating. Bluesquare made themselves available and performed a thorough assessment of the tech team and products in a limited time frame. Michel gave us the insights we needed on the strengths and weaknesses of the investment target in a clear and concise manner.

  • Bluesquare took charge of a full revamp of our platform, both on the front-end and back-end. Only a few months after go-live, it was already obvious that the revamp was a big success! Bluesquare helped us in taking the right technical decisions and structure our project so we can sustain our continuing growth. We continue and will keep working with them.
