How we work.

What we do

We invest at an early stage where the risk can be most challenging for a founder, but also the most rewarding for partnering and building long-term relationships with founders on their journeys.

For our financial partners, our investments provide the opportunity for better returns outside the public markets. We apply a rigorous approach to evaluating opportunities, prioritizing founders and teams with inquisitiveness and grit—attributes that also set Z2Sixty Ventures apart.

Because we recognize and empathize that building and running a company is challenging, we identify thinkers and doers and help them dig deep to become leaders who inspire others, communicate a clear vision, and create high-performing teams and businesses.

How we do it

We are super-connectors with strong, relevant industry relationships, and a world-class network at the ready. Frequent conversations with close contacts at large corporate, venture capital, private equity, angel networks, universities, and service providers are instrumental in our deal origination, operational support, due diligence, and ability to maximize exits.
