Jennifer P. Hopp — Managing Partner, ATO Ventures

Welcome to Valid Startup

"During the pandemic, many aspiring entrepreneurs attempted to start companies, only to discover that it was not nearly as easy as some influencers like to make it sound. There is plenty of information online telling you WHAT to do, but there isn't enough information on HOW to do it. 

As a successful entrepreneur and experienced startup investor, I knew that this was a problem I could help solve.  I built Valid Startup as an interactive step-by-step program based on my 25+ years of experience starting, running and investing in startups in Silicon Valley. It is designed to help you avoid the costly mistakes most entrepreneurs make when not doing enough validation work before launching."

Additionally, Jennifer holds an MBA with certificates in Entrepreneurship and in Management of Technology, also from the University of California at Berkeley.

"Jennifer possesses the qualities we look for in a GP. She has a powerful, unique investment thesis and is rigorous in her vetting process. What makes Jennifer stand out, though, is how well respected she is by, not only the entrepreneurs in her portfolio, but also the entrepreneurship community at large." ~Lo Toney, MP, Plexo Capital

At ATO Ventures, she helped us with customer discovery, validating product-market fit, and making our business more attractive for other investors, which resulted in us closing a multi-million dollar, oversubscribed round last year. She has been always a great resource and helped us think outside the box and think of unique business opportunities. She also connected us to resources inside PR that will facilitate our go to market." ~Maryam Ziaei, CEO, iSono Health
