    Synergy Ventures seeks seed and early stage investment opportunities in U.S. medical device startups, with typical funding levels of $250K to $1M in its initial investment. The firm looks for start-up opportunities that can demonstrate clinical efficacy of their product or technology early on and create strong potential for partnership and acquisition. Synergy assists its portfolio companies in developing corporate partnerships in Japan at the appropriate time, which can provide significant strategic and economic benefits. The firm's sister company Synergy Partners International helps clients develop investment and strategic partnering relationships between U.S. medical technology companies and Japan corporations interested in expanding their medical business segments. Synergy's primary investment interests are in start-up companies developing medical device and diagnostic products that address major diseases and conditions prevalent in industrialized countries as the population ages (such as cancer, cardiovascular and neurological diseases, orthopedic problems, respiratory conditions, and gastrointestinal disorders). The firm has participated in over $1 billion in equity and other financial transactions for private U.S. medical technology companies.
