In recent years, quantitative hedge funds have made a killing in public markets with their data-first approach (coronavirus aside). But skeptics say the strategy makes less sense for venture capital, where public financial reports are nonexistent. Six-year-old venture firm SignalFire is among those seeking to challenge that assumption. The firm, which tends to invest in the seed stage, says it is using a plethora of data to source deals and help portfolio companies find early employees. The firm raised $500 million for a pair of funds in December.
