The Origin of ColabEdu

From a Real Problem to an Open Standard

ColabEdu was not born in a corporate software lab or in the offices of a tech giant. It was born at home, driven by the urgent need to solve a real, daily problem in the trenches of elite education.

The “Patient Zero”: The International Baccalaureate (IB)

It all began by observing the frustration of a frontline educator. My wife, Spanish, a former entrepreneur and current IB Spanish (International Baccalaureate) teacher in the San Francisco Bay Area (Silicon Valley), faced the monumental challenge of evaluating her students daily.

The IB curriculum is one of the most demanding in the world. It requires the use of hyper-complex rubrics, constant formative assessments, and a level of detail in the feedback that consumes countless hours of a teacher’s personal life. Generic educational AI tools or simple “chatbots” were not sufficient; they lacked the rigor, consistency, and strict alignment with standards required for high-level assessment.

We needed something better. We needed a deterministic engine capable of assessing exactly as a teacher of the highest level of demand would, without deviating from the official curriculum.

The Technological Solution: Architecture and New Generation

With decades of experience in software engineering and systems architecture, I decided to build that engine. I designed the Open Assessment Specification (OAS) as an “assessment as code” infrastructure.

She was our “Patient Zero” and our shadow Pedagogical Director. Each iteration of the OAS standard, each definition of Rubric or Recipe in YAML, was validated against the real demands of her IB Spanish classes in California. If the system was robust, transparent, and precise enough for her, it would be capable of supporting any governmental or institutional educational system in the world.

But building a modern standard requires connecting with the future of education and technology. Therefore, the technical and conceptual development has been deeply supported by the talent of the University of California (UC). My two children, immersed in the technological and medical-research university ecosystem of UC Santa Cruz (UCSC) and UC San Diego / UC San Francisco (UCSD/UCSF), have actively collaborated on the project. They have contributed technical freshness, knowledge in algorithmic research, and the essential vision of the new generation of students who demand transparent, fair, and cutting-edge tools.

Pioneers in Open Source and Public Administration (Andago and LinEx)

Our vision of building open technological ecosystems is not new. Years ago, from Andago Ingeniería —the technology consultancy my wife and I founded— we participated in the development and deployment of pioneering Open Source projects in Spain, such as the historic LinEx (gnuLinEx) project.

That project demonstrated that public administration and education could rely on free software to guarantee technological sovereignty, democratize access to technology, and avoid vendor lock-in (dependence on proprietary providers). Today, with the advent of Artificial Intelligence, the challenge is exactly the same, but on a much larger scale. The lessons learned building open infrastructures for the State decades ago are the foundations upon which we now build the OAS standard.

A Global Bridge: Spain, Hispanic America, and Silicon Valley

We are Spaniards based in the Bay Area. This position grants us a unique strategic advantage: we deeply understand the regulatory context of our country (from LOMLOE to the sovereignty of co-official languages), and at the same time, we operate in the global epicenter where foundational AI models are developed.

Added to this is an extensive track record directing and deploying IT projects in the vast majority of Hispanic American countries. This direct technical experience on the ground provides us with a deep understanding of the region’s reality, and it is what underpins our absolute commitment to technologically standardizing education throughout the Spanish-speaking world.

Today, ColabEdu represents the union of three fundamental pillars:

1. Enterprise-Level Systems Engineering (Deterministic and scalable architecture).
2. Elite Pedagogy (Real-world validation under the rigor of the International Baccalaureate).
3. University Research and Talent (The University of California network).

The “Concierge” Teacher Network

The adoption of a new technological architecture in classrooms requires human support. For our initial pilot projects, we have deployed a network of Concierge Teachers: master’s students in Bilingual Education in Spain and Mexico.

The role of these Concierge Teachers is vital: they act as pedagogical engineers who automate OAS specifications, refine AI-generated exercises to ensure their quality, and provide direct technical and methodological support to lead teachers in their classes. This network allows us to rapidly iterate the technology in real environments, and our goal is to aggressively expand this model to a growing number of countries.

We are not here to sell a canned product; we are here to offer an open technical standard (OAS) backed by human talent, which will allow governments, institutions, and educators to audit, share, and automate formative assessment with the utmost guarantee of sovereignty and pedagogical rigor.
