4.1 Brazilian law

A model fine-tuned for Brazilian law (CF88, CLT, CDC, STJSTF case law) with RAG over up-to-date case law. Market ~R$160bi/year. Feasible for a small team with a law-firm partnership.

• Base: Qwen2.5-14B or Llama 3.3-70B; pipeline SFT → DPO → daily case-law RAG; B2B

  SaaS product (R$2–10klawyermonth).

4.2 Finance

An LLM fine-tuned for Brazilian sector fundamental analysis, CVM/BACEN compliance, or personalized wealth management — feasible and valuable.

4.3 Education

An ENEM/college-entrance tutor fine-tuned with RAG over exam notices + a historical question bank. Market: ~5M entrance-exam candidates/year.

4.4 The pattern that repeats

In all of them: the domain's proprietary data (case law, regulatory series, question bank) is the defensible advantage; the foundation model is a commodity. The partnership with whoever holds the data (firm, brokerage, prep course) is the asset — exactly the thesis of Part V, doc 07-kode-case-study.kmd.

Data as the bottleneck: in applied and scientific domains, data — not compute nor architecture — is the bottleneck. Your strategic advantage starts there.
