Mentor Testimonials

  • “I feel privileged to be in a position to bring an outside perspective to other business builders; JVMS created a selfless, supportive, and focused platform for mentors to genuinely feel they are a part of something bigger than themselves.” – Rony Sellam
  • “My experience with JVMS as a mentor has been incredibly rewarding and has added a new dimension to my professional career that has been missing for many years. As business owners and entrepreneurs it is easy to lose ourselves in the initiatives that consume us and our businesses day in and out. When a business gets to a level of maturity, we sometimes forget the passion and energy that we brought to it in the founding days and deal with more mundane, although important issues. Engaging with JVMS has allowed me to put my entrepreneur hat back on and has given me a path to re-engage with the community and give back by sharing my experience to assist new companies in accelerating their business plans and processes and hopefully help avoid some of the mistakes I made when in the same position. It has not been a one way relationship. I have also benefited from the energy and passion that I see with the ventures we are mentoring and have brought some it back to my own businesses and re- energized our teams to be more creative and forward thinking.” - Alex Beletsky
  • “I had the privilege of participating in a few mentoring meetings, and was very impressed with the high caliber mentors JVMS has been able to bring to the table; as well as the enthusiastic, creative and passionate entrepreneurs that we have been able to meet with. JVMS is the right framework to bring these mentors and entrepreneurs together, and help these great minds in our community get their ideas to the next level.” – David Benaim
