Marianna Novellino, MIT Masters in Systems Design & Management 2015

BonBillo helped increase my network… The network that BonBillo offers on mentorship, presenters, people that help you build your team and work on your soft skills as a leader. It’s something that you don’t find everywhere.

BonBillo was an opportunity to apply an approach and get some good feedback to see if there is viability in an idea. This is about whether there is commercial viability for a startup.

Rhea Advani, Founder of Indriya

It’s really difficult to get so many experts together over a short period of time and learn so much from them. It was really valuable information we got with a lot of real life examples. It was great to have people tell you this is how it’s done – we’ve all been through it and there’s a way to structure it no matter where you are in the process.
