Raging Bull

Ivan Lee, the founder, leads investment decisions. Lee brings an operator's perspective rather than a traditional finance background, having built the ThaiExpress restaurant group to $100 million in revenue before its acquisition. The firm does not list additional investment partners, suggesting Lee functions as the sole decision-maker or lead under a concentrated structure.

The firm draws on Ivan Lee's network as a serial entrepreneur in consumer and technology sectors across Asia. Raging Bull's website indicates a broad sourcing model that includes both inbound founder relationships — such as its deal with the crowdfunding platform New Union — and active scouting across mobile, internet, and healthcare verticals. There is no evidence of a formalized co-investor circle or proprietary database-driven origination process.

Raging Bull operates as a private investment fund structured more like a venture capital firm than a traditional family office. Ivan Lee deploys personal capital from his ThaiExpress exit, but the fund actively invests across seed to growth stages, participates in syndicated rounds alongside other institutional investors, and maintains a diversified portfolio — behavior that blurs the line between a family office and a generalist PE/VC manager.

The firm targets early-stage seed rounds, expansion, and growth-stage companies. Portfolio examples span the full spectrum — from seed-stage commitments in food-tech platforms to growth rounds like the $17 million Autolotto raise and the $10 million Tabsquare AI expansion. This stage-agnostic approach allows the fund to continue backing companies as they scale rather than concentrating exclusively on initial inception capital.

The firm's website does not publish explicit negative screens. Its stated focus covers technology, mobile, the internet, and healthcare, while its disclosed portfolio includes assets in crowdfunding, live streaming, gaming, electronic records management, and food delivery. Hard-tech, industrial, and traditional energy or infrastructure sectors appear absent from the public portfolio, suggesting a deliberate emphasis on digitally enabled, consumer-facing business models.

The capital originates from Ivan Lee's 2009 sale of the ThaiExpress restaurant group, which he founded and expanded across multiple Asian and Australasian markets. The exit generated $100 million, which Lee subsequently reallocated into technology and healthcare investments through Raging Bull. No external limited partners or co-investment vehicles are disclosed, indicating the fund remains a proprietary balance-sheet vehicle.

There is no publicly available information suggesting Raging Bull operates a linked philanthropic foundation. Ivan Lee's entrepreneurial honors — including the Singapore Youth Award for Entrepreneurship — reflect recognition for business achievement rather than charitable initiatives. The website lists no donor-advised funds, operating charities, or impact-investing carveouts.
