COMMUNITY FEEDBACK
Testimonials
Very, very, very positive. It helped me enter the ecosystem with an active voice. It’s not just about being a founder; it’s about being someone who can take the reins of what they are doing and have an impact on others. And the community that we are creating and helped create in the country is something we should be very proud of.
Co-Founder & CEO at Simplifyer
Usually when I am talking to someone, I end up recommending 351. And I recommend it because I truly believe people can extract value from it. Actually I have recommended 351 countless times, so maybe that means something!
Entrepreneur & Architect
It is fundamental to have these small but great experiences that open doors to the world. For Francisco [my 13-year-old son], it was the discovery of a different world, where he could talk to people from different areas and shape his profile as an entrepreneur.
