Javi Santana

Early life, education and programming

Santana was born in 1981 in the province of Valladolid, Spain. A 2018 El Progreso interview identifies him as “Valladolid, 1981,” while a 2026 CEEI Valencia profile says he grew up in a small village in the province. He has described a family background in agriculture; a 2016 elDiario.es profile reported that he had helped his father and grandfather with farm work and that, in 2005, he chose an agricultural topic for his university final project. That project became the basis for Agroguía. ^{[29] [2] [1]}

An older curriculum vitae preserved on Santana's website lists a Technical Telecommunications Engineering qualification in electronic systems from the University of Valladolid (1999–2003), followed by a Telecommunications Engineering degree completed in 2006. It gives the final-project title as “Sistema de ayuda al guiado de maquinaria agrícola mediante GPS bajo plataforma Pocket PC” (“GPS-based assistance system for guiding agricultural machinery on the Pocket PC platform”). ^[6] primary source

His archive also documents a parallel interest in graphics, games, demoscene programming and low-level software. A September 2005 development diary for MakeFight, a vehicle-building fighting game submitted to the ArtFutura 2005 competition, describes using Python, OpenGL and a C-based physics library. A 2024 retrospective says that his entry into 3D programming was prompted by seeing a real-time graphics demo while participating in programming IRC channels when he was around twenty. ^{[7] [8]} primary sources

Early technical career

Before CARTO, Santana's self-published résumés describe a mix of embedded systems, game technology, web development and applied engineering. One résumé says that while studying he did freelance development and worked as a television engineer, including database-migration software, control software for center-pivot irrigation and technical work for a regional television broadcaster. It later lists work at M2DEV on real-time 3D architectural visualization, at Unkasoft on game-development tools and mobile games, and at Wellness Telecom on Python/Django web systems. ^[9] primary source

A second archived CV additionally lists R&D work at Algor on distributed systems for embedded Linux and at GMVending on embedded Linux, touch interfaces, C/C++, Python, JavaScript, Qt and OpenGL. ^[6] primary source

Agroguía

Agroguía began as Santana's university final project. The system used GPS and a mobile computer to show agricultural operators which parts of a field had been covered, particularly during tasks such as spreading fertilizer or applying pesticides. Santana wrote in January 2007 that he had started selling early units experimentally, reinvesting the proceeds in product improvements and targeted advertising. ^[10] primary source

Independent reporting later described the product as a GPS guidance system installed in tractors, with emailed reports showing treated areas, elapsed time and gaps. By 2016, elDiario.es reported that Agroguía had around 2,000 customers and had been profitable for most of its existence. The same article described its online-sales model and the close relationship between Agroguía and CartoDB technology. ^[1] independent

A 2013 CARTO article described Agroguía using CartoDB for real-time statistics and mapping, and identified Santana as the product's originator. It also connected the project to his family's agricultural background in Valladolid. ^[11]

Santana continued experimenting around the product. In 2009 he wrote that an augmented-reality prototype, which combined GPS with a camera view for farmers, had won the industry category of a 3M competition. ^[12] primary source

In a 2017 farewell post, Santana said that Agroguía had run for more than twelve years and that the business was transferred to SmartRural on 3 July 2017 after he and his collaborators had devoted less time to it in its later years. He described the product as deliberately narrow, technically simple and maintained for years without unnecessary rewrites. ^[13] primary source

CARTO / CartoDB

Santana's connection to CartoDB grew directly out of Agroguía. In the 2016 elDiario.es profile, he recalled that Javier de la Torre contacted him after becoming interested in agricultural data collected by Agroguía. The initial project did not continue, but the relationship led to other collaborations, including work for Google, and Santana subsequently joined CartoDB. The article identified him as the company's CTO at the time. ^[1]

Santana's present-day site summarizes his CARTO period as 2012–2018, “founding engineer to CTO,” and says the company grew from zero to $8 million in annual recurring revenue during that period. The revenue figure is Santana's own retrospective claim and is therefore not treated here as independently verified. ^[3] primary source

The period coincided with CartoDB's transition from a small geospatial technology company into a venture-backed software business. In 2016, elDiario.es reported clients including NASA, the United Nations and Twitter and noted the company's $23 million financing round. Santana's own 2015 post about that funding emphasized the operating pressure attached to venture capital rather than treating it as personal wealth. ^{[1] [14]}

His blog from the CARTO years increasingly shifted from graphics and embedded development toward data systems, APIs, geospatial infrastructure, enterprise software, technical-team scaling and production reliability. The site's index includes posts on vector tiles, local search, on-premise software, engineering-team growth and, in 2018, a farewell entry titled “Adiós CARTO”. ^[3]

BBVA

After CARTO, Santana worked at BBVA as Data Services Lead. This role is stated in his public speaker biography and in a 2026 CEEI Valencia profile. ^{[2] [15]}

In later personal writing, Santana characterized the bank period as a short corporate interlude before starting Tinybird. His 2019 introduction to Tinybird says that he left a comfortable corporate 9-to-5 role because he valued choosing how to work and working with people with whom he shared a strong professional affinity. ^[16] primary source

Tinybird

Santana co-founded Tinybird, a real-time data infrastructure company. His current website dates the project from 2018, while a September 2019 essay gives one of the earliest detailed public descriptions of its model: a product for exposing large datasets through fast APIs, combined in the early phase with data-analytics consulting as a way to understand customer problems. ^{[3] [16]}

Santana's 2019 and 2020 technical essays show the early architecture taking shape around Python, C++ and ClickHouse, with an emphasis on minimizing dependencies, understanding the lower layers of the stack, keeping the development environment simple and allowing technology choices to follow the needs of the business. In 2020 he described a stack that also used Redis, ZooKeeper, Nginx and Ansible, while arguing that unavoidable system complexity should be understood rather than hidden behind additional abstractions. ^{[17] [18]}

In a year-end 2020 review, Santana wrote that Tinybird had grown to eleven people and had handled a project processing 12 trillion rows in a single day. A later Tinybird engineering article described the same Black Friday workload and connected the team's experience with earlier high-load projects at CARTO. ^{[19] [20]}

Tinybird subsequently raised a $3 million seed round in 2021, a $37 million Series A in 2022 led by CRV and Singular Ventures, and a $30 million Series B in 2024 led by Balderton Capital. TechCrunch reported in 2024 that the company had tripled revenue over the previous year and named Vercel, Canva and FanDuel among its customers. ^{[21] [22]} independent

Tinybird's current author page identifies Santana as a co-founder and shows continued technical writing on ClickHouse, ingestion, data engineering and real-time systems through 2026. ^[23]

Podcasts, interviews and public appearances

Santana has been interviewed repeatedly about software engineering, entrepreneurship, CTO work, data infrastructure and product development. Taken together, these recordings provide a substantial first-person oral history of his career: the earliest items focus on the developer-to-CTO transition at CARTO, while later appearances revisit Agroguía and BBVA and document the formation, architecture, product model and management philosophy of Tinybird. Because statements made by Santana in interviews remain primary-source testimony, this draft attributes them to the relevant conversation when they are not independently corroborated.

Long-form interviews and podcast appearances

What the interviews add to the biography

The interviews make several career transitions much clearer than résumé-style biographies do. In K Fund's 2018 episode, Santana describes the move from individual developer to CTO as a change in kind rather than merely a promotion: recruiting, onboarding and organisational communication become part of the technical job. Four years later, K Fund's CTO roundtable revisits the same theme after Tinybird, explicitly discussing how the role must change as a company scales. ^{[28] [33]}

The 2023 SeedRocket and Datola conversations provide the clearest spoken bridge between Santana's successive products. He recounts Agroguía as a practical commercial project rather than an attempt to “be an entrepreneur,” describes how that work connected him with the people behind Vizzuality/CARTO, contrasts the startup environment with his BBVA period, and then explains Tinybird's founding around large-scale data problems and customer work. These are first-person accounts, but they align in broad chronology with the earlier independent reporting on Agroguía and CARTO. ^{[34] [35] [1]}

By 2024–2025, the interviews shift from “how the company was started” to “how the company should operate.” The Product Leaders episode documents Tinybird's unusual decision to distribute product responsibility broadly rather than rely on a conventional product-management department; the Manfred interview extends that operating philosophy to AI-assisted development and hiring; and the Crane interview shows an analogous shift in go-to-market thinking from explaining technical mechanisms to explaining customer value. ^{[40] [42] [43]}

The two-hour JuegoConSentido interview is useful as a map of topics to verify elsewhere because it covers parts of the biography that shorter company profiles omit, including burnout, the BBVA transition and personal interests. Claims made there—especially numerical claims about fundraising—are not automatically treated as verified facts in this page unless supported by independent reporting. ^[38]

Selected conference talks and technical sessions

Writing and public technical archive

Santana's personal site functions as both a blog and a technical archive. The public GitHub repository contains a _posts directory whose earliest visible files are dated 4 August 2003. The current site index numbers 678 entries through 2026, while the repository also includes older CVs, experiments, project pages, talks, source material and a dedicated photo directory. ^{[3] [4] [5]}

The archive makes it possible to follow changes in Santana's interests over more than two decades: early C/C++, Python, OpenGL and game-development experiments; GPS and embedded systems; building and selling Agroguía; software-team practices; geospatial and data infrastructure at CARTO; and later databases, ClickHouse, real-time analytics, product strategy and LLM-assisted development.

Engineering and product ideas

Across his writing, Santana repeatedly treats software engineering as a product discipline rather than a separate technical function. In the 2020 Tinybird architecture essay he wrote that product and technology form a single system in an early-stage company, and he argued for conservative, understandable technology where possible. ^[18]

His Tinybird writing also emphasizes fundamentals, small technical teams, low dependency counts, performance and direct contact with customers. The 2019 technology-selection essay argues that technical sophistication should follow validation of the business problem, while the original Tinybird essay presents consulting as a form of intensive user research rather than as a failure to build a software product. ^{[17] [16]}

A similar pattern appears much earlier in the Agroguía archive. In 2007 Santana wrote that targeted advertising, customer trust and refusing unsuitable sales mattered more than simply maximizing the number of units sold. His 2017 farewell to Agroguía praised narrow scope and long-lived “working code” over fashionable rewrites. ^{[10] [13]}

Selected chronology

Wikipedia sourcing assessment

A standalone Wikipedia article would need to be built primarily from significant, independent coverage about Santana himself—not from his own blog, Tinybird's site, speaker bios or company announcements. The strongest biographical source located for this draft is the 2016 elDiario.es feature, which covers his background, Agroguía and CartoDB in depth. The 2026 CEEI profile/interview adds recent career context, while TechCrunch provides strong independent coverage of Tinybird as a company. ^{[1] [2] [21] [22]}

The personal archive is exceptionally useful for finding leads—project names, dates, talks, awards, technologies, company transitions and historical claims—but most of those details should be upgraded to independent sources before being placed in an actual biography of a living person.

The podcast/interview archive is similarly useful for chronology and for Santana's own account of decisions, but an interview does not become an independent source merely because it is hosted by a third party. Xataka and El Progreso provide editorially framed independent interviews; most podcast episodes are best treated as primary testimony and used with attribution. ^{[26] [29]}
