Generative AI development services for technology. Build copilots, RAG, and production-ready AI workflows with secure integration and evaluation by Logiciel.
We combine applied AI engineering, software development, data integration, and testing to build useful generative AI for SaaS products, developer tools, support platforms, and multi-tenant applications.
mapping user goals, workflow steps, required context, failure cases, and measurable outcomes before selecting a model
connecting models to product documentation, account-approved records, code-adjacent knowledge, and tenant-scoped application context with appropriate retrieval and access boundaries
selecting and integrating models, prompts, structured outputs, and orchestration based on quality, latency, and cost requirements
implementing entitlement checks, structured validation, and human approval for consequential product actions
testing tenant isolation, feature completion, answer grounding, output validity, latency, and cost per useful request with representative scenarios
building APIs, services, retrieval, tool connections, and workflows around SaaS platforms, developer tools, product APIs, support systems, and existing engineering workflows
adding observability, fallback behavior, release controls, usage monitoring, and continuous improvement after launch
AI, software, data, UX, and QA engineers work across discovery, architecture, integration, evaluation, deployment, and improvement.
Specialists strengthen your team across model selection, RAG, workflow integration, evaluation, security boundaries, and production engineering.
A focused engagement builds one copilot, document workflow, AI product feature, knowledge application, or bounded agent against agreed acceptance criteria.
We assess user needs, business value, data readiness, failure risks, and integration requirements across SaaS products, developer tools, support platforms, and multi-tenant applications.
We build application services, model interfaces, prompts, orchestration, structured outputs, conversation state, and the product experience around the workflow.
We connect models to product documentation, account-approved records, code-adjacent knowledge, and tenant-scoped application context using ingestion, retrieval, metadata, permissions, and source visibility where appropriate.
We engineer tenant-scoped context retrieval, model access, quotas, feature flags, tracing, and product API integration for SaaS applications.
We implement data boundaries, identity, tool permissions, auditability, and entitlement checks, structured validation, and human approval for consequential product actions.
We test tenant isolation, feature completion, answer grounding, output validity, latency, and cost per useful request, including edge cases and failures before release.
We implement logging, traces, usage and cost tracking, fallback behavior, model and prompt versioning, regression checks, and production support.
A method for ranking use cases by user value, data quality, integration effort, failure impact, and ability to measure outcomes.
A way to decide which responsibilities belong to the model, knowledge retrieval, deterministic application logic, tools, and human review.
A framework for checking tenant boundaries, evaluation coverage, latency, usage cost, fallback behavior, and rollback before rollout.
We review the target workflow, users, product documentation, account-approved records, code-adjacent knowledge, and tenant-scoped application context, permissions, dependencies, and business outcomes.
We define model access, context, retrieval, APIs, structured outputs, evaluation, access controls, fallbacks, and acceptance criteria.
We develop the application, connect SaaS platforms, developer tools, product APIs, support systems, and existing engineering workflows, and implement model, retrieval, validation, and review logic.
We evaluate tenant isolation, feature completion, answer grounding, output validity, latency, and cost per useful request, plus missing context, invalid outputs, restricted data, and integration failures.
We release with observability and operational ownership, then improve quality, latency, costs, and workflows using real usage signals.



Teams that needed to ship fast, and did. Here's what partnering with Logiciel felt like from the inside.
They involve designing, building, integrating, testing, and operating applications that use generative models for tasks such as summarization, drafting, retrieval-based assistance, structured extraction, and workflow support.
Custom development connects models to your applications, knowledge, identity, business rules, and evaluation requirements. A packaged chatbot may be sufficient for simpler use cases but may not fit complex integrations or controls.
Usually not. Many workflows can use an appropriate existing model with application logic, RAG, structured outputs, and evaluation. Fine-tuning or custom training should be justified by the task and data.
RAG is useful when responses require current, private, domain-specific, or source-verifiable knowledge. It should be designed around permissions, source quality, retrieval relevance, and answer evaluation.
We design data flows, identity and access checks, retrieval permissions, logging, tool boundaries, and deployment choices around the sensitivity and requirements of the specific workflow.
We test representative tasks for grounded answers, output validity, task success, failure behavior, latency, cost, and workflow-specific risks rather than relying on model demos alone.
We enforce tenant and user permissions in identity, retrieval, application services, and tool access before context reaches the model, then test cross-tenant leakage scenarios.
Tell us what you want to improve across SaaS products, developer tools, support platforms, and multi-tenant applications. We will help define the data, architecture, controls, and engineering plan to build it.
