Diego Partida

I build production software for money, property and factories — the systems that break loudly when they are wrong.

01About

I build the systems money moves through. Invoicing that answers to the SAT, payment rails that reconcile themselves, and shop floors that finally left the spreadsheet behind.

Two years shipping SaaS that real businesses depend on: Next.js and TypeScript front ends over Node.js services, with the unglamorous parts done properly — CFDI 4.0 issuance and cancellation, SPEI transfers landing against the right contract, a part's whole lifecycle auditable down to the serial number.

I like the problems where correctness is not a matter of taste. A tax stamp is either valid or it is not. A balance either reconciles or someone loses money. That constraint is the interesting part.

Products I own

Three companies I am building — as founder, as co-founder, and as the person on call when they break.

01Founder · 2026

Caudare

Tu caudal, claro.

Personal finance for Mexico without handing over your bank password. You upload a statement PDF, it is parsed in memory and never stored, and every transaction lands in one of 150+ categories. Accounts, investments, crypto, property, receivables and business P&L roll up into a single net-worth figure.

CourtValue

Stop betting on hunches. Start betting on numbers.

A quantitative tennis model that prices a match before the market does. Surface-adjusted Elo feeds a Barnett–Clarke serve simulation, calibrated out-of-sample, and the result is compared against sportsbook odds to surface genuine edges across ATP, WTA, Challenger and ITF. Every forecast is logged pre-match and graded in public.

Brisa

Every message becomes a lead.

A WhatsApp-first CRM. A voice note, a photo or a single line of text becomes a structured, AI-enriched lead on its own, so sales teams stop losing deals inside a chat thread. Built solo end to end — product, architecture, billing and go-to-market.
