🚀 ABOUT US

In 10 years, all companies will operate a non-financial system. As we see it, it's either Dcycle or bust.
Sustainability should not be a cosmetic exercise. 🍃 Dcycle is the startup born to make that happen.

Amidst the regulatory, financial, and technical maze that has attempted to equate sustainability with Non-Financial Statements, the industry has made access to information more complex. When faced with a black box, the keyholder becomes indispensable. In this context, the only way to elevate sustainability to the level it deserves is by adding transparency and eliminating all the bullshit.

At Dcycle, we are determined to fulfill a mission: giving companies control over sustainability.

And we are building an amazing team to make it happen.

HOW WILL YOU DO IT?

At Dcycle, we take inspiration from models like La Masía at FC Barcelona, one of the most prestigious and recognized football academies in the world. La Masía is much more than just a training facility; it is a true talent factory that has shaped some of the greatest legends in football.

Its success lies in a holistic approach that combines a clear playing philosophy, an innovative methodology, and a long-term commitment to the technical, tactical, and personal development of its players. Beyond football, La Masía also prioritizes the education and well-being of its talents, shaping well-rounded individuals prepared for challenges both on and off the field.

At Dcycle, we embrace a long-term vision and a comprehensive development philosophy. We are not just looking for immediate results, but for people with the potential and determination to make a difference. We prioritize professionals who share our mission: giving companies control over sustainability.

We don't just evaluate technical skills or past achievements; we focus on individuals with curiosity, critical thinking, and a commitment to continuous learning. We want people who don't just complete their tasks but challenge ideas, bring new perspectives, and drive change. With this approach, we create an environment where personal and professional growth go hand in hand, and every challenge becomes an opportunity to innovate and make an impact.

The people who belong in Dcycle are:

• Nº1 - Willing to pay the price to become better, passionate about what we do, energetic, and hungry for challenges.

• We fix what's broken → with ownership, autonomy, and responsibility.

• We take humor seriously → spending time together is a pleasure.

• Intelligent → we learn quickly, are versatile, and technically brilliant at something.

The people who belong in Dcycle act:

• With confidence → whether acting autonomously or seeking opinions and getting involved; we value feedback as the only way to grow.

• Guided by metrics → we rely on key metrics to evaluate our efforts.

• Close to the customer → we maintain constant, iterative conversations with our customers and prospects to learn from our experiments (both about the problems and the solutions we create).

• By taking risks → we understand that failure is the price of learning.
