YZi Labs, the family office founded by Binance co-founder Changpeng "CZ" Zhao, may open up to external investors, the Financial Times reported on Tuesday. "There’s always a lot of external investors interested and we will eventually consider turning it into an external-facing fund," Zhang said. "We're forming our team, when we have that expertise...we'll be open to external investors," she said. Family offices are not open to external investors as they manage the wealth of a single family, so do not raise money from outside sources. YZi Labs did not respond to CoinDesk's request for comment.
