Frequently Asked Questions

What's the difference between Free, Professional, and Expert?

Free unlocks 4 foundation tracks (SQL, dbt, Python, Data Modeling) and 2 foundation projects fully (dbt warehouse, API ingestion) — plus a Phase 1 preview of every Pro track and project. Professional ($29/mo or $299/yr) adds all 4 Pro tracks (Batch, Streaming, Data Quality, Platform) and 17 Pro production projects — 19 projects accessible total when you count the 2 foundation projects you keep from Free. Pro also includes all 5 career paths, a Phase 1 preview of Expert tracks/projects, 1 senior code review per month, and a verifiable certificate. Expert ($49/mo or $499/yr) adds both Expert tracks (AI & Vectors and Staff Engineering) — covering RAG, agentic, LLM pipelines, MLOps, vector DBs, system design, product thinking, and technical leadership — plus all 11 Expert projects (30 projects total), 1 senior code review per month, and 1 × 45min 1:1 mentor session per month with a staff/principal engineer.

How does this compare to bootcamps?

Our Expert plan ($499/year) gives you 30 production-ready projects with full source code for 1/12th the price of traditional bootcamps ($6,000–10,000). You get 80% of the practical value at 8% of the cost — and you keep your projects forever.

Can I try before I buy?

Yes. Free includes 4 foundation tracks (SQL, dbt, Python, Data Modeling) and 2 starter projects fully unlocked, plus a Phase 1 preview of every Pro and Expert track + project. No credit card required.

What's included in the projects?

30 projects total across 7 tracks, each with 4 progressive parts covering real-world production scenarios. Free unlocks 2 foundation projects fully. Professional adds 17 Pro production projects across the 4 Pro tracks (Iceberg, Spark, Flink, Kafka, Airflow, dbt) — so 19 accessible at Pro. Expert adds 11 more Expert projects — AI capstones (RAG, LLM eval, agentic, LLM ingestion, predictflow, AI inference, AI cost) and Staff Engineering capstones (event routing, A/B testing, access control, staff engineer playbook) — for 30 projects total. Every paid project ships with full source code and deployment guides.

Can my employer expense ai-de.net?

Yes — Professional and Expert subscriptions are designed to be expensable. We send a monthly receipt and a learning-budget letter you can attach to your reimbursement. If you need an annual invoice or different format, contact support.

Can I cancel anytime?

Yes. Cancel anytime in one click. You keep access through the end of your billing period, and any projects you've shipped remain in your account permanently.

Do you offer team or enterprise plans?

Yes. Volume discounts kick in at 5+ seats. At 20+ seats we set up private cohorts with a dedicated reviewer and custom project tracks aligned to your stack (AWS / GCP / Azure / Snowflake / Databricks). At 50+ we add custom curriculum and an on-site workshop. SSO (SAML / Okta / Google Workspace), centralized billing, and a named reviewer are included on all enterprise plans. Use the Talk to us button above to start a conversation.

What payment methods do you accept?

All major credit cards (Visa, Mastercard, Amex), Apple Pay, and Google Pay through Stripe. Enterprise plans support invoicing and ACH/wire transfer.

Do you offer student discounts?

Yes — students get 20% off Professional and Expert. Contact support with your .edu email or student ID for a discount code.
