4 sections · 11 lessons
Define the customer ask in retrieval terms, then translate it into measurable objectives, constraints, and data readiness criteria.
2 lessonsDesign ingestion, segmentation, indexing, retrieval, reranking, and grounding controls so the model uses evidence safely and cites it well.
3 lessonsBuild customer-specific evaluation, production guardrails, and debugging methods, then apply them in a compliance-heavy case study and post-launch feedback loop.
5 lessonsConsolidate the core decisions into a durable mental model for customer-specific RAG design and future FDE delivery.

Customer-specific RAG in an FDE engagement starts with a customer request, messy data, and a need to ship something reliable. This course shows how to turn that situation into a retrieval system with clear requirements, grounded answers, customer-shaped evaluation, and production guardrails. It is aimed at forward-deployed engineers, product teams working with embedded customers, and anyone who needs to make RAG work in a specific environment rather than in a demo.
The course covers requirements discovery, data inventory, indexing strategy, retrieval and reranking, answer grounding, and evaluation against customer definitions of correctness. It also addresses deployment architecture, monitoring, debugging hallucinations and misses, a healthcare prior auth case study, and post-launch iteration with customer feedback.
From project managers and operators to founders, analysts, and teams adopting AI, Fenzo is for people who want to get better at the work they already do.
Anything from using AI for project planning and analysis to improving workflows, decision-making, communication, and delivery. If you can describe the skill or task, Fenzo can build a course around it.
Yes. Tell Fenzo what you do, what you’re trying to accomplish, and where you’re stuck, and Fenzo will shape the course around your role, your goals, and the work you actually have to do.
No. Fenzo adapts to your starting point, so you can begin with the fundamentals or jump straight into more advanced work.
Yes. Fenzo for Business puts the whole team on one plan — shared seats, courses you can assign, and reporting on who has finished what.
See Fenzo for BusinessYou start by describing your goal or taking a short skill benchmark. Fenzo uses that context to identify gaps and shape the learning experience around them.

What the science says
Students in lecture-only classes are 1.5× more likely to fail.
How Fenzo does it
Every Fenzo lesson is interactive. No passive reading or watching, ever.

Skill retention over time · with vs. without practice
What the science says
Offloading thinking to AI erodes the very skills you’re trying to build.
How Fenzo does it
Fenzo makes you do the thinking — guided, but never done for you.

Long-term recall · retrieval vs. re-reading
What the science says
Recalling information beats re-reading it for building durable understanding.
