2 reviews for Gustavo Grieco SL
What was the objective behind your collaboration?Gustavo Grieco SL and Earthical Innovations partnered to build a platform that enables people to sponsor meaningful global actions instead of giving physical gifts. For example, users can plant corals in the oceans of Bali as a birthday gift. The Earthical Innovations platform allows people to fund these initiatives seamlessly from anywhere in the world. The product was successfully launched across India, Spain, and the United States.
What did you enjoy the most during your collaboration?The strong technical guidance and clear direction from the team stood out. They handled the complexities of a global launch exceptionally well, including managing diverse action types and integrating Stripe for payments. This made it possible to move quickly and launch the platform efficiently.
Are there any areas for improvements?None. Given the global nature of the launch, there were initial challenges with time zone differences between Barcelona and the United States. However, the team adapted quickly and was highly accommodating, making collaboration across regions smooth and effective.
