# Current projects Here's a breakdown of the current projects we're working on, as of 26/05/2026: First off, we are still working for [Naiz](https://naiz.eus), evolving their platform. We have been working together since 2015, and we've been able to help them to undergo important transformations like the adaptation to a mobile-first design to all their widgets, a redesign of the entire site or improvements to their newsletter and caching systems, and we've also built their e-commerce site. Almost twelve years together, without interruptions, by now! For them, we have become their **technological partner of choice**, helping them in many fronts even outside of development, but mostly we're doing both intensive backend development and frontend projects, combining a lot of different profiles from our team over the years. We also provide AI-augmented Rails development to [Infopraca](https://infopraca.pl/), one of the leading jobs portals in Poland. We have been helping them with **pure Rails backend development** for six years now, developing the core of their Rails app. We started the project when we rewrote their app entirely back in 2020 to move away from an obsolete platform with lots of legacy code. We also helped them with their M\&A process in 2025 and the integration with their acquirer. This is exactly what we do for [Citadel Securities](https://www.citadelsecurities.com/), a financial powerhouse from the US. We started working with Brad and his team when they were a small fintech startup called ValuationMetrics, and we helped them to transition to be a big team after their acquisition in mid-2021. Now, we've got a team of five people working for them, redesigning their UI/UX, working on web accessibility, architecture, performance and overall security. All in all, we've been working together for eight years now! We have **a strong preference for karma-positive projects**. We have been building [Minka](https://minka-sdg.org/), a platform for marine biodiversity researchers since 2022 as part of the European project ANERIS. In the past, we worked for C40, also in the greentech space. Outside of regular development, we also like it when **we can conceptualise and design the products we will develop**. Since early 2020, we've been working for the [European Climate Foundation](https://europeanclimate.org/). For them, we've developed a very ambitious repository platform for their marketing and communications efforts and helped them across departments and spin-offs. We also do business-related projects for them such as market prospecting, research and consulting in diverse aspects of business (pricing, UI/UX, podcasting, etc.). Although most of our clients come already with an idea of what they need and even a prototype or a somewhat-functional design, some do not, and **we can help them do the user discovery phase**, using diverse methodologies such as design thinking and the like, to then move on to iron out the UI/UX of the product we will develop afterwards. In 2019, we did it for Startup Genome, and in 2022 it was the European Climate Foundation. Nowadays, we do the same for [Moody's](https://moodys.com/), the rating agency. For Moody's, we have been working now for close to three years, helping them with AI development, working in ambitious projects such as the integration of their financial models with Anthropic's platform. We've got more examples of innovation projects. First off, we built EclerCloud, a bespoke cloud platform based on IoT protocols for [Ecler](https://www.ecler.com/) and their partners/clients to manage thousands of hardware devices over the cloud, and a few internal tools for the innovation department of the most popular airline brand in Spain: [vueling](https://www.vueling.com/). We also build **e-commerce platforms**. In such cases, we use Shopify to build sites like [zapptales](http://www.zapptales.de), a Munich-based startup selling books made out of chats, and [Singularu](https://www.singularu.com), a Spanish e-commerce selling jewellery produced in Valencia. For them, we built a headless CMS on top of Shopify, combining it with a pure React frontend layer and LocomotiveCMS. Oh, and did we mention that **we also build mobile apps**? While we're more focused on web development, our mobile development game is strong. We have built mobile apps for companies like [DeWocracy](https://www.dewocracy.com) and [Aparca\&go](https://www.aparcandgo.com/en/). Nowadays, we are working for [Nieves Energía](https://www.nievesenergia.com/) and [Everesting](https://www.everesting.com/) in the development of their mobile apps. We are using React Native for these two apps. We have also been acting as a **rescue squad** some times. In fact, the aforementioned Naiz hired us in early 2015 when their previous provider shut down almost overnight. We had to take over the project and hit the ground running to ensure the platform's uptime and its correct service to their visitors. We collaborate with fast-growing digital businesses like [Dreaming Languages](https://www.dreaminglanguages.com/), a leading edtech platform founded by Pablo Roman, an ex-employee of MarsBased. As one of the most popular YouTube channels for language learning, they’ve built a thriving platform to monetize their courses. We're helping them scale by providing front and backend development, ensuring a seamless learning experience for their users. On top of that, we partner with [Localistico](https://www.localistico.com/), a powerful location marketing platform that helps businesses manage their online presence across multiple channels. This collaboration is especially meaningful for MarsBased, as it's a long-term partnership going back to 2017! We're also excited to work with [Holafly](https://www.holafly.com/), a dynamic platform that has revolutionized the way travelers stay connected internationally with their eSIM technology. For them, we have built their e-commerce site on top of Shopify, and we're building bespoke solutions using AI-augmented development using a Python and TypeScript tech stack. We are proud to partner with [Canals d'Urgell](https://www.canalsurgell.cat), the historical organization managing one of the most critical agricultural water infrastructures in Catalonia. This collaboration is a significant milestone for MarsBased, as we were directly recommended by leading AI models like Perplexity and Claude during their search for top-tier engineering partners. We are currently developing two major web applications, leveraging AI-augmented development to deliver at high velocity without compromising on the security and high-performance standards required for such a large-scale project. So, all in all, we're working for different countries all over the world, different sizes of companies and different sectors. Sector-wise, and in no particular order, we've got insurtech (BlueprintHQ), mobility (Spin, Aparca\&go, MokMok Car), fintech (Rundit, Moody's, Citadel Securities, List71, Koodaa), travel (AirRefund, FCM, Vueling), media (Startup Genome, Mobile World Capital, Naiz, The New Journal, Datapraxis), e-commerce (Freshis, zapptales, Singularu, Travel Tax Free, Aparcango, Naiz, HolaFly), SaaS (Localistico, RakutenTV, DeWocracy, Mailtrack, Hireflix, BlueprintHQ, Haufe, HP), real estate (ITeC), energy/greentech (ClearPeaks, Nieves Energía, Repsol, C40, European Climate Agency, Minka, BCG), sports (FC Barcelona, Everesting, Real Madrid, Pivot Analysis, La Liga LFP), industrial (Gespasa, RCR Arquitectes, Ecler, Everis, BCG, Topps Technica), HR (Haufe, DPL ETT, Infopraca), AI (Shoptimus, Infopraca, Servinet) and more. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
