Venture capital funding for life sciences startups dropped in 2012, but some investors remain optimistic. While the sector requires large investments over long periods, recent fundraising like Third Rock Ventures' $516 million shows some feel the risk is worth the potential reward. However, others note the economic slowdown has investors favoring later-stage companies over startups. There is no consensus on investment trends, as priorities vary from basic research to applied sciences that can more quickly yield results. Overall, the life sciences sector remains high-risk but could see more investment if startups can prove market traction.
