Luis Valdich, an MD at Citi Ventures, the VC arm of Citigroup, says the market for startup funding has been changed by the emergence of SoftBank's Vision Fund. VCs now have to move quickly to invest in attractive startups given the heavy competition from funds like SoftBank and others. Despite the "tricky dynamic," Valdich sees possibilities in the sector as the fund looks to support different businesses within Citigroup.
