What we do
MarsBased is an AI-augmented development consultancy of expert software engineers. Driven by our Research, Plan, and Implement methodology, we leverage advanced tools like Claude Code to supercharge our efficiency and engineering precision. Our core technical foundation is rooted in building high-quality web and mobile products using Ruby on Rails, JavaScript (in all flavours: React, Node.js, Vue.js, React Native, Angular...) and Python, effectively boosting companies at the intersection of business and technology. We started off in early 2014 as a web-only development shop using Rails and Angular because our founders Jordi and Xavi had been using these technologies in their previous companies. Over the years, we've expanded our technological horizons to new technologies, products, and modern development workflows.
Technologies & services
As a consultancy, we deal with many different clients, from all countries and all sectors. We've worked with clients from San Francisco to Singapore, from Germany to the Basque Country. As for the sectors, we've worked in fintech, we've built marketplaces, we've developed smart cities platforms, we've refactored other people's codes, we've done code audits and built dozens of web and mobile apps.
You can find a description of the technologies we use in the services pages of our website:
AI-augmented Development (using Claude Code)
The aforementioned technologies are used mostly for the web, but we also do mobile apps, just not so often. In this case, we use Ionic or React Native, but we never do native mobile development. We also do lots of e-commerce with Shopify and install and develop on the Consul/Decidim platform. Furthermore, our expertise in AI isn't new—we have been integrating AI features into client products since as far back as 2014, and today we combine that experience with our internal AI-augmented development workflows.
In 2019, we started to offer a new service: tech due diligences. A lot of VCs and M&A companies don't have the competencies, the personnel or the bandwidth to assess the status and integrity of the technology of the companies they want to invest in or acquire. We help them to audit several aspects of the technology of these companies like the infrastructure, the choice of programming languages and frameworks, scalability, security issues, code quality and much more.
Community
We spend a considerable amount of time and resources to develop community around us. Helping both the tech and startups communities in Barcelona, we have become one of the most active companies in the ecosystem.
In the Community section of our website, you will find more detail about the stuff that we do.
