Harmatrix is an independent software studio. We design, build, and run custom products for companies in Uruguay and abroad — from mobile applications to AI‑powered data platforms — with senior engineering on every line of code.
Full products from first sketch to production: web platforms, internal tools, APIs, and the integrations that tie a business together. We own scope, quality, and delivery.
iOS and Android apps with native-grade quality — built, signed, and shipped to the App Store and Google Play, with over-the-air updates and release engineering handled for you.
LLM-powered features that survive contact with production: retrieval pipelines, agents, evaluation harnesses, embeddings, and the data engineering underneath them.
Resilient services on AWS: containers and serverless, infrastructure as code, encryption, observability, and the operational discipline to keep systems healthy at 3 a.m.
No hand-offs to junior teams. The engineer you talk to is the engineer who writes, reviews, and ships the code.
Working software over slideware: short cycles, weekly demos, and code that goes to real users early and often.
Straight answers in English or Spanish, honest estimates, and one accountable partner from kickoff to launch.
Harmatrix was founded in Montevideo in 2025 to do one thing well: build software that lasts, for clients who care about craft.
Led by its founding engineer — with two decades across data engineering, machine learning, and product development — Harmatrix works as a hands-on partner to startups and established companies alike, serving clients in Uruguay and exporting software services across the Americas. We keep the team deliberately small, the standards high, and the communication direct.
We typically reply within one business day. Remote-friendly across time zones; GMT–3 at home.
