Xside

Xside is a Buenos Aires-based development firm founded over 18 years ago by engineers Hernan Klein (CEO) and Osvaldo Olmos (CTO). The company works on product development, AI integration, cloud infrastructure, and Industry 4.0 projects, primarily for startups and mid-market clients across the Americas. They've shipped projects ranging from insurance-focused accident detection apps to book-sharing platforms and remote infrastructure monitoring systems.

The firm positions itself around three core practices. Intelligent Transformation uses AI, predictive analytics, and custom models to solve operational challenges—their accident assist case study (completed in 10 weeks for a US insurance company) shows this in action: a mobile app with LLM+RAG algorithms that evaluates accident severity and damage from images and data. Product Development covers end-to-end builds from concept to launch, applying Lean and agile methodologies. Their book-sharing app (launched 2023) hit thousands of downloads with built-in scanning, geolocation, and chat; the wellness app MVP (2023) shipped in three weeks using low-code tools. A third area, Digital Archaeology, involves studying existing codebases to support technical and business evolution.

Services and capabilities

Xside explicitly offers Generative AI work, Cloud Engineering & DevOps, Low-code development, and what they call "Intelligent Transformation." The accident assist app showcases AI depth: they handled LLM and RAG on AWS infrastructure with Flutter mobile clients. The digital twin platform (2024) combined WebGL rendering with AWS geospatial visualization for drone-fed infrastructure data—a project addressing remote preventive maintenance for a telecom operator in Argentina.

Low-code appears as a deliberate capability. The wellness app used FlutterFlow and Firebase to hit a three-week MVP deadline. This positioning suggests they see speed-to-market as a real constraint for their startup client base and have tooling to address it. Cloud infrastructure is recurring across projects: AWS appears in three of four case studies, paired with mobile frameworks (Flutter, FlutterFlow) and backend integrations.

Their stated methodology emphasizes proof of concept before full builds. Both the accident assist and digital twin projects opened with POC phases to validate feasibility and tool choices. Testing and validation appear rigorous—the accident app passed "rigorous validation testing by the client, confirming the accuracy of the results," and the digital twin was deployed through "rigorous testing to ensure its functionality and accuracy."

Notable work

The four published projects show breadth across verticals. The accident assist app (USA insurance company, 2024) combined AI model work with iOS/Android shipping. Xside assembled a specialized team—AI engineers, backend developers, mobile engineers—and shipped a production app in 10 weeks. The client's satisfaction centered on "the successful integration of AI and the usability of the application." The app now has market interest for expansion into other insurance products.

The book-sharing mobile app (Argentina startup, 2023) launched with image recognition (capturing book covers, auto-identifying via ML), geolocation, and chat. It hit "thousands of downloads" and "high retention rate" within months, becoming a functional reading community. The team worked within budget constraints by adopting an "agile and efficient development strategy."

The digital twin platform (Argentina telco, 2024) addressed infrastructure in hard-to-reach areas. Xside built an interactive WebGL viewer consuming drone-sourced imagery and geospatial data. The output: operators could perform remote preventive maintenance without site visits, reducing cost and risk. The client noted "precision and functionality."

The wellness app (Argentina startup, 2023) was a rapid MVP: content sharing, chat, AI-assisted search, built in three weeks on FlutterFlow and Firebase. It shipped on time and budget and received positive user feedback on ease of use.

How they work

Xside appears to run time-and-materials or fixed-scope engagements, with emphasis on speed and budget discipline. The wellness app case study explicitly highlights meeting a "three-week" deadline and delivering "within the allocated budget." They assign specialized teams to projects—separate AI, backend, mobile, and UX/UI specialists—rather than generalist pools. Communication patterns aren't detailed on the site, though case studies mention "close collaboration" between UX/UI experts and development teams, plus "usability testing" and "agile methodology" with "rapid iterations and continuous adjustments based on immediate feedback."
