Who exactly are we?

Our story is the one of a group of Cloud and technology enthusiasts who always had a clear goal : make things much easier for tech companies. Since no one was really stepping up to fill that gap in Spain’s Cloud sector, we figured—why not build our own product?

We started small, and now we’re over 130 people and still growing. Today, Jotelulu’s products are used in thousands of offices and businesses in retail, construction, industry, hospitality, transportation, and more, across over 8 countries in Europe and the Americas.

Every step we take is driven by the desire to do things better, bring something new, and shake things up—because that’s the only way innovation truly has meaning.

What are we up to these days?

After years of growing and iterating on our current product, we’re now at a really exciting turning point. Soon, we’ll start envisioning Jotelulu 2.0—the reinvention of our product—and we’d love for you to lead that change from a design perspective, working closely with our product and tech teams.
