LawTech turns 20+ years of Brazilian public court decisions — STJ, STF, CARF, TRFs — into defensible, explainable outcome intelligence for tax litigation teams.
Brazilian tax law firms face a crippling information asymmetry. Jurisprudence shifts without warning — a single STJ or CARF reversal can transform a bulletproof claim into a losing one overnight.
Senior associates spend 10–15 hours per case manually researching precedent, unable to deliver the defensible, quantified risk assessments their managing partners need to make go/no-go decisions.
"We need numbers, not opinions. No black box allowed — the analysis has to hold up in front of the managing partner."— Validated in 22/22 primary market research interviews
STJ, STF, and CARF decisions shift precedent unpredictably. Firms have no systematic way to track exposure across their entire active docket in real time.
Generic AI tools exist — but without citation trails, confidence intervals, and reasoning traces, lawyers cannot defend AI-assisted analysis to partners or clients.
10–15 hours per case on manual precedent research. At 6–12 active cases per senior associate, this is a structural capacity constraint — not a workflow problem.
Without quantified outcome probability, firms systematically over- or under-price risk at intake — costing clients and the firm alike on case selection.
Our proprietary pipeline continuously ingests and indexes decisions from STJ, STF, CARF, TRF 1–6, and state tax tribunals — structured, searchable, and mapped to legal doctrine in real time.
A tax-litigation-specific embedding and prediction model — not a generic LLM — outputs outcome probability, expected duration, and present-value claim economics calibrated to Brazilian legal Portuguese and doctrine.
Every prediction comes with a full citation trail, reasoning trace, and confidence interval. The output is designed to be cited in an internal risk memo — defensible to a managing partner or opposing counsel.
When a major STJ or CARF decision reverses precedent, LawTech automatically runs a portfolio-impact assessment and delivers a 48-hour brief on which active matters are affected — and how.
Beyond win/lose probability, LawTech outputs expected case duration, NPV of the claim under multiple outcome scenarios, and suggested settlement ranges — replacing gut-feel with model-backed economics.
Named-user SaaS, invoiced to firm CNPJ via boleto or card. LGPD-compliant public-data architecture — no privileged client data enters the system. IT/InfoSec pack included at onboarding.
We start with mid-size tax law firms in São Paulo — 11 to 30 lawyers — where the pain is sharpest, the DMU is fastest, and the willingness to pay is highest.
From that beachhead we execute a disciplined bowling-pin expansion: solo firms, large firms, corporate in-house tax departments, then adjacent modules (labor, customs) and LatAm markets (MX, CO, AR).
We are currently onboarding lighthouse partners — mid-size São Paulo tax law firms willing to run a 90-day pilot in exchange for preferential pricing and direct product input.
