Digital product engineering
Launch new products, modernize complex systems, and strengthen engineering operations with transparent progress and measurable outcomes.
Rat Labs works with product companies, private teams, and high-growth innovators to launch new products, evolve complex systems, and strengthen engineering operations.
Our teams are built for real-time collaboration. We align on your roadmap, culture, and communication so decisions move faster, feedback loops stay tight, and execution stays efficient.
The portfolio spans new product development, platform consolidation, application modernization, and sustained engineering, accelerated by reusable AI workflows and delivery-tested patterns. Every engagement embeds the tools, guardrails, and operating habits that persist after we leave.
We deliver side by side with client teams. Dedicated pods integrate AI across the software development lifecycle for measurable impact on velocity, quality, and innovation.
We do more than engineer products. We engineer forward.
Core services
Design, build, and sustain digital products that perform reliably and securely. Modern architectures, intelligent automation, and AI-enabled workflows across the full engineering lifecycle.
Ship predictably with transparent progress and measurable outcomes. Build products, modernize legacy systems, and sustain engineering velocity with AI woven through the lifecycle.
Engineer speed and reliability into every platform. Optimize performance, security, and operations with automated delivery and measurable confidence.
Build confidence into every release. Turn testing into an intelligent quality approach that connects evidence to action across delivery.
Bring the right level of AI automation to every body of work. Reusable prompts, agents, templates, and reference architectures proven in delivery, not theory.
Capabilities
The same capability map clients expect from a full product-engineering partner, delivered by senior people who still ship.
Cloud platform engineering, migration, systems integration, DevOps engineering, and site reliability engineering.
Backend, full stack, web, and mobile development with product-minded visual design when the surface matters.
Automated QA (SDET), manual QA where judgment is required, and release readiness that leadership can trust.
Data platform engineering, business intelligence, machine learning products, and forward-deployed AI and LLM workflows.
Technical product management, technical program management, engineering management, and business analysis.
Embedded teams with owned outcomes: feature delivery, modernization, sustainment, and reliability.
Products
Apps and platforms we build and lead. Real systems in production.
Consumer product
Daily lessons, spaced-repetition flashcards, and native audio for Valencian, Catalan, Galician, and 20+ more. Built and operated by Rat Labs on Go and Rust/Leptos.
AI commerce
Technical strategy, architecture, and delivery from infrastructure through storefront integrations and the agent layer that lets sellers run their business in natural language.
Internal product
Turns a raw idea into a live landing page in minutes and measures real demand, so founders get market signal early and avoid building the wrong thing.
What sets us apart
The same bar as a mature product-engineering partner: measured delivery, AI-enabled depth, and continuity you can plan around.
Modern architectures, intelligent automation, and AI-enabled workflows inside frameworks built for complex product programs.
Refined models that balance agility with accountability. Scalable delivery for modernization and sustainment.
Teams work in your hours, embedded with client teams for faster iteration, tighter loops, and shared accountability.
Low churn on the people who know your system. Stability across programs, anchored by a culture that keeps shipping at a high bar.
Reusable workflows, agents, and blueprints that cut engineering lift and keep compounding after the first engagement.
Tools, guardrails, and operating habits your team can own after the engagement ends. The system is the product.
