Exclusive: Data Collective raises $125 million for ‘opportunity’ fund by Dan Primack @FortuneMagazine December 22, 2014, 10:53 AM EST E-mail Tweet Facebook Google Plus Linkedin Share icons Data Collective, a Silicon Valley venture capital firm focused on big data startups, has quietly raised $125 million for its first-ever “opportunity fund,” which will focus exclusively on later-stage rounds for existing investments. This is nearly as much money as DCVC raised for its third general fund ($140m) earlier this year, and is part of a broader trend whereby early-stage VCs raise funds for the purpose of preventing dilution in large follow-on financings for their most promising portfolio companies.
