Job Description

Front-end Developer - Join our Madrid (Spain) team!

Company Introduction

We are disrupting the Venture Space. We looked at today's startup ecosystem and came up with a plan to solve a systemic flaw: while investment qualification continues to improve, first-time entrepreneurs continue to burn funds, and waste time solving the same major problems over and over again. Our superpower comes from our ability to offer entrepreneurs 'out-of-the-box' solutions to these problems, empowering them to focus on growing their ventures.

We are based in Boston Massachusetts and Madrid Spain.

Our focus is on the future of business hospitality. Building the smartest spaces for the best human experience.
