Founder Testimonials

“Jeff’s experience as both a founder and seasoned operator have been very helpful to ChemDirect. He’s a great listener, with a knack for asking incisive questions that advance my, and our teams, thinking. Equally important, he’s a practical business builder and problem solver.  For example, whenChemDirect had a growing order volume but lacked sufficient cash reserves to support the transactions, we didn’t know what levers to pull, but Jeff quickly understood our challenge and calmly engaged his network to help us find a solution. Within the week, we had a direct connection with an executive who underwrote the transactions via a line of credit. This was a very big deal for the company.”

“Jeff is a highly-valued investor, board advisor and strategic partner for our business. He’s a ‘roll-up-your-sleeves’ investor that has actively helped across multiple dimensions of the ChemDirect business: fundraising, financing, recruiting, product, strategy, etc. His depth of fundraising and marketplace building experience are particularly noteworthy, and have already added a great deal of value. Because he was a founder prior to becoming an investor, Jeff has a great perspective on tough decisions and an empathy for the challenges of building a great company, especially in the earliest innings when so much still needs to be figured out. He has also seen “hypergrowth” and been part of scaling large marketplaces; these insights are directly relevant for us as we make key decisions to grow the ChemDirect marketplace. ”

“Jeff has been an invaluable support for Ceresa. Not only was Jeff eager to support us financially with his investment, but he has been supportive and hands-on helping us with introductions to other investors (angels and funds alike). Critically, Jeff also understands that one of the most important things for any early stage company is sales.To that end, he has actively made multiple introductions that have led to deals for Ceresa. For me personally, I love having Jeff as a sounding board - he is someone who understands tech, but also has gone through the founder and operator journey himself. We have barely scratched the surface on how Jeff can add value to us - and I'm excited to continue tapping into his wisdom and experience as the Ceresa journey continues. Plus, Jeff is just a stellar human being, so great to have on your side. ”

“Jeff is consistently among the most responsive and supportive  investors on our cap table.  He has been an amazing investor and partner to Glacier, helping us work through multiple business challenges that are unique to building a robotics company. This particular expertise is both rare and hugely valuable.  For example, Jeff proactively brought to our attention and helped us think through how debt financing could be an important, non-dilutive lever to to support our commercial roll-out – a tactic that none of our other investors had thought through.  The next generation of entrepreneurs solving important real world problems will benefit tremendously by having Jeff in their corner. ”

“I've known Jeff for 15+ years; as colleagues at Better Place, as friends and fellow travelers in tech, and now—much to my delight and to the benefit of our company—as an investor in Modern Treasury. His intellect, collective set of experiences, work ethic, and extensive network will meaningfully alter the odds of success for any company that Jeff chooses to get involved with.”
