# MarsBased

> MarsBased is a senior-only, fully-remote software consultancy founded in Barcelona in 2014. We build, scale, and rescue complex web applications for CTOs and technical founders, running an AI-augmented Research–Plan–Implement workflow on every project. We are engineering-first: no branding, no body-shopping, no low-budget websites.
