Think Jerry is awesome?
Vouch for them.

Shrad Rao
They're my investor  •  CEO, Wagepoint and CEO, Synapp6.
Jerry is the definition of the phrase 'one smart cookie'. His advice is well thought out, logical and generally on point. He takes time to l ... isten and understand before giving you his point of view. He also understands that you might not implement all his suggestions, given your own understanding of the situation, and that lack of ego (esp. in his position) makes him pretty awesome as far as Mentors go.
Connell McGill
They're my friends  •  Co-Founder, CEO, Enertiv. Previously Co-Founder & CEO at Enertiv, Techstars..
I am the co-founder and CEO of a leading hardware company focused on energy management in NYC. Jerry is an advisor, investor and a friend wh ... o has been instrumental in the growth of my company. He's a life long entrepreneur who loves what he does, and he impresses that on everyone around him, along with helpful feedback and insights for first-time entrepreneurs. I definitely would vouch for Jerry as an excellent advisor and entrepreneur - I meet with him regularly to bring him up to speed with the challenges that I am facing, and he's seen it all before and provides excellent suggestions.
