BIGU

What BIGU does

BIGU Group is a Hong Kong-headquartered professional services firm providing corporate compliance, audit, tax, payroll, pre-IPO advisory, trademark registration, outsourced accounting, and ESG and advisory services. Operating from Suite 309, 3/F, Chinachem Golden Plaza, 77 Mody Road, Tsim Sha Tsui East, Kowloon, the firm reports an active client base of over 2,000 across Hong Kong, Mainland China, and international jurisdictions including the Greater Bay Area, Macau, the British Virgin Islands, and the Cayman Islands. Its client segments include SMEs, listed companies and large enterprises, pre-IPO companies, and cross-border enterprises requiring multi-jurisdictional corporate services.

The firm's service portfolio is designed to cover the full corporate lifecycle — from incorporation and company secretarial filings through annual audit and tax compliance, MPF and payroll administration, pre-IPO restructuring, and ongoing listed-company governance support including ESG reporting and transfer pricing. Core technical capabilities include Hong Kong Companies Ordinance audit work, MPF setup and employer tax return filing, Hong Kong and China trademark registration through IPD and NIPA, and pre-IPO readiness work covering financial transparency, internal control optimization, and compliance system building. The firm does not develop proprietary technology platforms and operates on a traditional professional services delivery model grounded in practitioner expertise and regulatory knowledge rather than software or AI systems.

BIGU Group runs a sales-led, direct-engagement go-to-market, with client acquisition driven by website inquiries, professional network referrals, and direct outreach to enterprise and mid-market buyers. It maintains a trilingual website (English, Simplified Chinese, Traditional Chinese) and a presence on Facebook, Instagram, LinkedIn, and WeChat, and publishes a media section covering Hong Kong tax, listing rule, and Web3/stablecoin regulatory developments. Revenue is generated through professional service fees on a per-engagement or recurring retainer basis; the firm is privately held, with no disclosed revenue, headcount, funding rounds, ownership structure, or named customers.
