Hi, I'm Facundo

AI legal assistant that helps law firms work faster with their documents. Firms upload case files (PDF/DOCX/TXT) and the system processes them automatically — making everything searchable through natural language and keyword queries combined. Lawyers chat with AI that answers questions citing the exact source documents, with different AI models handling different tasks (Claude for deep analysis, GPT-4o for quick questions). Full SaaS product with Stripe billing and usage limits per plan, background document processing, per-user data isolation, and production-grade security. Reduced document processing time by 70%.

Personal fiscal operations app built for Spanish freelancers under the Beckham Law regime. Manages the full invoicing lifecycle — create, edit, track, and export invoices as PDF. Tracks deductible expenses with automatic VAT calculation per quarter, estimates annual IRNR (model 151), and generates a personalized tax calendar with reminders for quarterly VAT filings (models 303/390) and Social Security deadlines. Single-user, local-first architecture with zero cloud dependency.

All-in-one SaaS for creators and marketing teams to plan, generate, and publish content from a single place.

Includes a unified asset gallery, a credit-based billing system tied to Stripe, and a publication queue that prevents duplicates. Replaces the chaos of juggling 8 separate tools.

Decision OS for founders that turns operational noise into actionable product decisions. Captures signals from users, feedback, and team intuitions, then uses AI to synthesize them into problems, generate hypotheses, and suggest experiments to validate them. Includes a "feature graveyard" that automatically detects zombie features worth killing. An AI copilot with tool-calling helps throughout the workflow. Supports team collaboration with roles and invitations, Stripe billing with free/pro/team tiers, and generates executive video reports with Remotion.
