LeanXcale is founded on years of in-depth research in distributed systems and data management. Professors at the Distributed Systems Laboratory of the Polytechnic University of Madrid decided to discard more than 15 years of previous research and start from scratch to build a radically different transactional manager that would be able to scale without limits. The result: a first version of what would become the LeanXcale scalability algorithm, which solved one of the main bottlenecks of relational databases in the last decades.

With the support of European R&D funding, a patent on scaling query processing was filed in 2010 and another patent was filed in 2011 to protect the invention on ultra-scalable transactional management. Both were granted.

It was then that one of the researchers, PhD. Ricardo Jiménez-Peris, began to conceive the idea of building a complete database based on these algorithms.

He spent a week in Silicon Valley giving some talks at leading technology companies such as HP, Microsoft, Salesforce-Heroku and EMC-Greenplum (now EMC-Pivotal). From the excellent feedback he received in the cradle of technology, he decided to prepare himself for the mission of bringing this new disruptive technology to the market. He received training in entrepreneurship from the Polytechnic University of Madrid, an institution very active in the creation of startups through its entrepreneurship program ActuaUPM (which creates more than 20 startups a year).

In 2014, the LeanXcale project was submitted to the EIT Digital Idea Challenge, where it won one of the main awards in the Future Cloud category.

In mid-2015, Dr. Ricardo Jiménez, left his teaching and scientific career to become CEO of the company. Helping LeanXcale in its first steps was Glenn Osaka, a successful Silicon Valley entrepreneur and former VP of several large technology companies (HP, Cisco, Juniper Networks) and also a member of PayPal's first advisory board.

EIT Digital advised LeanXcale during 2015 by providing valuable assistance and hosted LeanXcale's offices. At this stage, the new company continued to work on its database and additional innovations, with the support of the European Framework Programme.

In 2017, LeanXcale was selected by Red Herring as one of the top 100 European startups of the year.

In 2018, deep-tech investment fund Bullnet Capital became the first private investor.

After almost 10 years since this journey began, LeanXcale continues to meet milestones and position itself as the best technological solution to the challenges it faces.
