About Rho Ventures
We invest across most high growth sectors of today’s economy and have developed deep expertise and relationships in Information Technology, Communications, New Media, Healthcare and New Energy.Since 1981, Rho Ventures has been investing in innovators that redefine the status quo. Rho’s investment philosophy does not fit a conventional model,much like the visionary innovators we back. We believe that formulaic approaches to investing lead to risk averse strategies that stifle innovation and differentiation. We actively avoid restrictive boundaries around ideas, growth opportunities and entrepreneur profiles. To find extraordinary opportunities, we are not bound by a particular stage of investment and do not shy away from contrarian ideas.We believe that great companies take root in unconventional places and that successful entrepreneurs frequently break the mold. The ideas we back come from a variety of sources: an MBA student who is trying to change new media advertising practices; an experienced entrepreneur seeking to commercialize a disruptive biofuels technology; or an executive looking to spin out and develop an abandoned asset developed by a pharmaceutical company. We are seasoned investors who have backed more than 200 companies through multiple cycles. Identifying interesting opportunities and providing capital is just the beginning. We offer deep-sector expertise in today’s high-growth markets, but we do not let any one area of knowledge guide our overall investment strategy.Ultimately, we look for entrepreneurs who we can help make very big waves, not just stir the waters and move on to the next venture.
