Product studio · Since 1994

Products people use, designed and built end to end.

Citruslab is a product studio with thirty years of design and engineering behind it and a select network of specialists around it. We work with the best tools of the moment, AI agents included, and direct them with the judgment that only comes from shipping. Original, robust products, delivered fast.

Approach

Creative, solid, fast.

Creativity

A point of view comes first

Every project starts with a concept, an interface and a brand worth remembering. Generic is easy to produce; distinct takes taste, and that part is never delegated.

Functionality

Engineering you can build on

Architecture is set by people who have shipped production apps on their own. You receive a product that holds up in real use, and a codebase your team can read, extend and trust.

Efficiency

The pace of a much larger team

A small senior team, working with AI agents under close direction, covers the ground of a far bigger one. You see working software early and talk directly to the people making the decisions.

Citruslab, since 1994

One studio, from first sketch to shipped product.

Citruslab has built for every wave of interactive media since 1994: the early web, broadcast and motion graphics, e-commerce and enterprise systems, digital publishing, and native apps for iPhone, iPad and Mac. The tools change with every wave. The standard stays the same.

The studio is led by Alejandro Ramos Galdo, original founder of Sogni AI and the developer behind the CoinMarketCap iOS app. He has carried products from first sketch to the App Store on his own, and brings that range to every project: strategy, UX and UI, brand, native development and launch.

Around him is a select network of designers, engineers and media specialists, brought in as each project demands. Clients work directly with senior people, and the team stays as small as the problem allows.

The standard comes from more than software. Alejandro is a music producer with four albums and five EPs released as The Sudden, a skydiver with more than 12,000 jumps, a world record and R&D contributions to the sport, and a former Pan American karate champion.

Based in the United States. Has lived and worked in Italy, Spain, Australia, Costa Rica and Venezuela, and works in English, Spanish and Italian.

Native apps & platforms

iOS and macOS in Swift and SwiftUI, React Native, AI model integration, real-time data, and the web systems behind them.

Product design

UX and UI from concept to pixel-level polish: prototyping, onboarding, and design systems.

Brand, motion & media

Identity, marketing sites, motion graphics, music and launch material that match the product.

Zero to one

New products taken from idea to launch: strategy, roadmap, first release, and the iterations after it.

AI-accelerated delivery

Agent workflows directed and reviewed by senior people, for shorter timelines without giving up craft or code quality.
