Multi-Family Office

Updated:

Bloc

Bloc is a San Francisco-based multi-family office founded in 2018 by Bobby Lee and Yishan Zhu, investing in early-stage software and crypto.

Bloc

Bloc was founded in 2018 by Bobby Lee and Yishan Zhu, two operators with backgrounds in technology and finance. Lee previously held roles at companies including Coinbase and Airbnb, while Zhu's experience spans venture capital and product leadership. The firm was structured to consolidate the investment activity of multiple families, each contributing capital to a pooled vehicle for direct investments. Bloc's strategy covers venture-stage equity, growth equity, and selected crypto token investments. The firm has made public investments in companies including Skiff (a privacy-focused productivity platform) and Syndicate (a blockchain-based investment protocol). Bloc focuses primarily on US-based companies but has also deployed capital into European and Asian opportunities. Asset classes include private equity, digital assets, and select public equities. The firm operates with a lean team of fewer than 15 professionals, based solely in San Francisco. Bloc has not disclosed any philanthropic vehicles or separate operating businesses. In October 2023, the firm co-led a $10M seed round for Skiff alongside other family offices (per Crunchbase, October 2023). Bloc's structural differentiator is its platform model — it functions neither as a traditional single-family office nor as a closed-end fund. Instead, it aggregates deal flow and due diligence for a consortium of families, charging management fees on committed capital. This hybrid structure allows families to access institutional-quality deal sourcing without building their own in-house teams.

How does Bloc source proprietary deal flow?

Does Bloc maintain philanthropic structures, and how are they separated?

What is Bloc's known posture on co-investments alongside external GPs?
