In addition to capital, the start-ups are supported with simplified market access (world market leaders from the Heilbronn/Southwest Germany region). We support young, innovative technology companies with capital, know-how and contacts in medium-sized industry. With the project "Move2Grow" we enable international startups for the first time to participate in the development of the economic region Heilbronn-Franken beyond our investment horizon and to settle in this highly dynamic environment. Our goal is to further develop Heilbronn into one of the most successful technology locations in Europe.

Visionaries Club is a Berlin-based early stage VC fund backed by leading European digital founders and family business entrepreneurs.

Visionaries Club is divided into two micro funds: A (pre) seed stage fund leveraging its unicorn and digital founder LP network for very early and exclusive access to the most promising entrepreneurs across Europe. A second, separate Early Growth fund leveraging especially the fund's industrial LP network is intended to support the most promising European B2B companies in their early growth stage from Series B onwards with global reach and scale.

Zenda Capital is a thesis-driven, tech investment firm led by operators investing their own money. Our team started and exited three companies, and helped build the foundational team that scaled Twilio to $60Bn in market cap. We win by investing in category-dominant, B2B tech companies before they're obvious. We apply the same approach through which we’ve built a track-record of outperformance (7.5x MOIC, +110% IRR*) We partner with founders in the U.S. and LATAM as early as the formation stage, and support them through early-growth. Our first checks range from $250k to $1.5M, sometimes as co-founders of companies. We operate as business owners, and not just investors. Our focus is on helping founders solve problems for which there are no playbooks, but where our capital, operating experience, and network can help. 🔥 Our Mission We believe entrepreneurship is one of the greatest expressions of purpose by mankind. We look to find the best, overlooked, B2B entrepreneurs and be the first to invest in them. Our background as B2B founders and operators gives us an edge in connecting with these entrepreneurs and helping them win. 🧭 Guiding Principles Principle 1: Courage to be authentic → looking for opportunity where others don't, **and **believing first, when it’s non-obvious, is our path to greatness.
